Description

Technical Field

[0001] The utility model relates to the field of electrical component manufacturing, in particular to a tool for assembling workpieces. Background Art

[0002] Electromagnetic Interference (EMI) is often found on printed circuit boards (PCBs), which is caused by electromagnetic radiation and mutual induction between various components and wires. EMI may affect the normal operation of electronic devices, causing signal interference, data loss, or device failure. Using a shielding cover on the PCB is an effective measure to reduce or eliminate these interferences.

[0003] The shielding can not only block or weaken the electromagnetic radiation emitted by the components on the PCB to prevent these radiations from interfering with other circuits or devices, but also prevent external electromagnetic waves from interfering with sensitive circuits and components on the PCB to ensure their normal operation. In addition, the shielding can also help maintain the integrity of the signal by reducing electromagnetic interference, reducing signal noise and bit error rate.

[0004] The shield can be securely mounted on the PCB by mechanical means. Choosing the right fixing method is crucial to ensure that the shield can is stable and not easily displaced after installation, and also to facilitate future removal and maintenance. Common mounting methods include using snap-on fixing or interference fit, which are widely used due to their simplicity.

[0005] In order to further improve the accuracy and efficiency of shielding cover installation, special tools are usually used. Using these tools can reduce human errors, ensure the correct fit between the shielding cover and the PCB, and also improve the installation speed and repeatability. However, the current tools still need to be improved in terms of ease of operation and installation accuracy. Utility Model Content

[0030] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] As mentioned above, in the field of electronic manufacturing, technicians have generally used professional tools to assist in the installation of shielding covers to improve the accuracy and efficiency of installation. These tools are designed to achieve a snap fit or interference fit between the shielding cover and the underlying PCB by applying vertical pressure to the shielding cover. However, conventional tools have certain limitations in practical applications.

[0032] First, during the process of applying pressure, conventional tools may not ensure that the shielding cover continues to be precisely aligned with the predetermined installation position on the PCB, increasing the risk of assembly errors. Moreover, if the shielding cover is offset during the installation process, it may not only cause the shielding cover to be installed improperly, but may also cause damage to the shielding cover or the PCB, or even breakage, affecting product quality and reliability. Furthermore, due to alignment issues and potential damage risks, conventional tools may not meet the needs of high-efficiency production, requiring additional time and cost for correction and quality inspection.

[0033] In view of the above situation, the embodiment of the utility model is expected to provide a tool for assembling workpieces. By using the tool, the workpieces can be assembled in a controllable and accurate manner, thereby improving the assembly efficiency and the quality of the assembled product.

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] See also Figure 1 , which shows a tool 1 for assembling workpieces provided by some embodiments of the utility model. The tool 1 comprises: a first accommodating portion 11 and a driving portion 12. The first accommodating portion 11 is used to accommodate a first workpiece W1 to be assembled. The driving portion 12 is used to drive the first accommodating portion 11 to move along the assembly direction and drive the first accommodating portion 11 to press fit the first workpiece W1 accommodated in the first accommodating portion 11 to the second workpiece W2 to be assembled.

[0036] exist Figure 1 In the embodiment shown in FIG. 1 , the tool 1 is configured to press the first workpiece W1 onto the second workpiece W2 from directly above the second workpiece W2 so as to assemble the two together.

[0037] In order to ensure that the first workpiece W1 does not move in directions other than the assembly direction during the assembly process, the first receiving portion 11 can be configured to drive the first workpiece W1 to move along the assembly direction. It should be noted that in each embodiment of the present invention, the assembly direction refers to the direction in which the first workpiece W1 moves when the first workpiece W1 is assembled to the second workpiece W2. Figure 1 In the embodiment shown in FIG. 1 , the assembly direction is the vertical direction.

[0038] In some embodiments of the present invention, Figure 1As shown, the first accommodating portion 11 may be formed with a recess 111 on its lower surface that matches the shape and size of the outer peripheral portion of the first workpiece W1, so that the first workpiece W1 can be partially inserted into the recess 111 and form an interference fit or transition fit with the recess 111. Therefore, the first accommodating portion 11 and the first workpiece W1 can move integrally by means of the friction between the two, and will not fall from the first accommodating portion 11. In other words, the first accommodating portion 11 and the first workpiece W1 can remain stationary relative to each other, and the first accommodating portion 11 can drive the first workpiece W1 to move together.

[0039] like Figure 1 As shown, the first receiving portion 11 can be connected to the driving portion 12. The driving portion 12 can not only drive the first receiving portion 11 to drive the first workpiece W1 to move toward the second workpiece W2, but also drive the first receiving portion 11 to continue to move toward the second workpiece W2 when the first workpiece W1 is in contact with the second workpiece W2, until the driving force provided by the driving portion 12 overcomes the friction force and deformation force between the first workpiece W1 and the second workpiece W2 so that the first workpiece W1 and the second workpiece W2 are assembled in place. The driving portion 12 can control the moving distance of the first workpiece W1 during the assembly process and the force and speed of the assembly to the second workpiece W2, which can significantly improve the consistency of product quality compared to manual press-fitting.

[0040] Some embodiments of the utility model provide a tool 1 for assembling workpieces, the tool comprising a first receiving portion 11 for receiving a first workpiece W1 to be assembled and a driving portion 12 for driving the first receiving portion 11 so that the first workpiece W1 is pressed into a second workpiece W2. Through the cooperation of the first receiving portion 11 and the driving portion 12, the first workpiece W1 can be accurately assembled to the second workpiece W2 with a controllable force and speed, avoiding the occurrence of incomplete assembly due to the movement of the first workpiece W1 in directions other than the assembly direction during the assembly process.

[0041] When the tool 1 is used to assemble the first workpiece W1 to the second workpiece W2, while the first workpiece W1 exerts a force on the second workpiece W2, the second workpiece W2 also exerts a reaction force on the first workpiece W1. The reaction force may cause the first workpiece W1 to move relative to the first accommodating portion 11. Figure 1As shown, when the first workpiece W1 is pressed into the second workpiece W2 in the vertical downward direction, the reaction force of the second workpiece W2 on the first workpiece W1 may overcome the friction between the first workpiece W1 and the first receiving portion 11, so that the first workpiece W1 moves relative to the first receiving portion 11 in the vertical upward direction, so that the first workpiece W1 further enters the recess 111 on the lower surface of the first receiving portion 11 in the vertical upward direction. This makes it possible that after the first workpiece W1 and the second workpiece W2 are assembled together, they may not be separated from the first receiving portion 11, that is, they are not separated from the tool 1. For example, when the total weight of the first workpiece W1 and the second workpiece W2 is less than the friction between the first receiving portion 11 and the first workpiece W1, the first workpiece W1 and the second workpiece W2 may remain connected to the tool 1. In this case, the operator is required to manually separate the first workpiece W1 and the second workpiece W2 from the tool 1. This separation process will not only affect the assembly efficiency, but may also cause the first workpiece W1 and the second workpiece W2 to be separated again due to improper operation, and may even damage the first workpiece W1 and / or the second workpiece W2.

[0042] In order to improve assembly efficiency and avoid damaging the workpiece, the tool 1 is further provided with a separation portion 13. The separation portion 13 may be provided in the first receiving portion 11 and configured to separate the first workpiece W1 from the first receiving portion 11 when the first workpiece W1 is pressed into the second workpiece W2. Figure 1 In the embodiment shown in FIG. 1 , the separation portion 13 is disposed in the recess 111 of the first accommodating portion 11, and can be configured to apply a downward force to the first workpiece W1 so as to separate it from the first accommodating portion 11. The separation portion 13 can be configured to uniformly and controllably apply a downward force to the first workpiece W1, thereby achieving efficient and stable separation of the workpiece from the tool 1, and avoiding damage to the workpiece during the separation process.

[0043] Some embodiments of the utility model provide a tool 1 for assembling workpieces. The tool includes a first accommodating portion 11, a driving portion 12 and a separating portion 13. Through the cooperation of the first accommodating portion 11 and the driving portion 12, the first workpiece W1 to be assembled can be accurately press-fitted along a predetermined assembly direction, thereby reducing the misalignment and offset of the first workpiece W1 relative to the second workpiece W2 to be assembled, and improving the assembly efficiency and accuracy. The separating portion 13 can ensure that after the first workpiece W1 is press-fitted to the second workpiece W2, the first workpiece W1 is automatically separated from the first accommodating portion 11, thereby avoiding offset or damage caused by human intervention. Therefore, for the entire assembly operation, the tool 1 can reduce the complexity and labor intensity of manual operation, improve the accuracy, consistency and efficiency of the assembly operation, and reduce the risk of damaging the workpiece.

[0044] In some embodiments of the present invention, the separation portion 13 may include a compressible member 131 disposed on the first accommodation portion 11 and capable of automatically restoring its shape.

[0045] The compressible part 131 is configured to automatically restore its original shape after being subjected to external force, so that after the first workpiece W1 is pressed into the second workpiece W2, the first workpiece W1 can be quickly and effectively separated from the first accommodating portion 11, thereby reducing the post-assembly processing time, further improving the overall assembly efficiency, and avoiding deformation and rupture of the first workpiece W1 due to long-term squeezing by the first accommodating portion 11 of the tool 1.

[0046] In some embodiments of the present invention, the compressible member 131 may be a spring, such as Figures 2 to 3 As shown. The compressible member 131 can be arranged in the first receiving portion 11 to be able to be compressed in a direction opposite to the assembly direction. When the first workpiece W1 has not yet been received in the first receiving portion 11, the compressible member 131 can be in an extended state, such as Figure 2 When the first workpiece W1 is accommodated in the first accommodation portion 11, the first workpiece W1 compresses the compressible member 131, as shown in FIG. Figure 3 As shown. The compressed compressible member 131 generates an elastic restoring force due to elastic deformation. When the first workpiece W1 and the second workpiece W2 are assembled in place and the driving unit 12 stops driving the first accommodating portion 11, the elastic restoring force of the compressible member 131 can act on the first workpiece W1 along the direction of its elastic restoration, thereby pushing the first workpiece W1 away from the first accommodating portion 11.

[0047] In other embodiments of the present invention, the compressible member 131 may be a hydraulic or pneumatic cylinder, such as Figure 4 and Figure 5 As shown. The compressible member 131 may include a cylinder 131A and a piston 131B. The cylinder 131A may be filled with liquid or gas. The cylinder 131A and the piston 131B may be configured to allow the piston 131B to move in the cylinder 131A in a direction opposite to the assembly direction to compress the liquid or gas in the cylinder 131A. When the first workpiece W1 has not yet been accommodated in the first accommodation portion 11, the piston 131B may be in an extended state relative to the cylinder 131A, and the liquid or gas in the cylinder 131A has not yet been compressed, as shown. Figure 4 When the first workpiece W1 is accommodated in the first accommodation portion 11, the force exerted by the first workpiece W1 on the piston 131B causes the piston 131B to retract into the cylinder 131A, and at the same time, the liquid or gas in the cylinder 131A is compressed, as shown in FIG. Figure 5As shown. The compressed gas or liquid causes the pressure in the cylinder 131A to increase and react on the piston 131B. When the first workpiece W1 and the second workpiece W2 are assembled in place and the driving part 12 stops driving the first accommodating part 11, the pressure in the cylinder 131A can act on the first workpiece W1 via the piston 131B, thereby pushing the first workpiece W1 away from the first accommodating part 11, accompanied by the first accommodating part 11 moving in the direction opposite to the assembly direction.

[0048] In some embodiments of the present invention, the tool 1 may include a plurality of separation portions 13 , and the plurality of separation portions 13 are evenly distributed relative to the first workpiece W1 , so as to evenly apply a force to the first workpiece W1 .

[0049] The compressible member 131 may act directly on the first workpiece W1 or may act indirectly on the first workpiece W1. Figures 2 to 5 The separating portion 13 may further include an abutting member 132 that is configured to be connected to the compressible member 131 and abuts against the first workpiece W1 when the first workpiece W1 is press-fitted to the second workpiece W2 .

[0050] In the illustrated embodiment, the abutment 132 may be plate-shaped, wherein the upper surface of the abutment 132 is connected to the compressible member 131, and the lower surface of the abutment 132 is used to contact the first workpiece W1. The abutment 132 may be arranged not to be in direct contact with the first accommodating portion 11, so as to avoid increasing the resistance that needs to be overcome for assembling the workpieces due to friction with the first accommodating portion 11. The compressible member 131 and the abutment 132 are arranged such that: before the first workpiece W1 is accommodated in the first accommodating portion 11 and before the first workpiece W1 contacts the second workpiece W2, the abutment 132 does not apply a force to the first workpiece W1, so as to prevent the first workpiece W1 from being pushed away from the first accommodating portion 11 in advance; as the first workpiece W1 contacts the second workpiece W2 and the first workpiece W1 continues to be pressed toward the second workpiece W2, the abutment 132 contacts the first workpiece W1 and moves toward the compressible member 131 under the pushing action of the first workpiece W1, thereby compressing the compressible member 131. After the first workpiece W1 and the second workpiece W2 are assembled in place, the compressible member 131 pushes the first workpiece W1 away from the first receiving portion 11 via the abutment member 132 during the process of restoring the shape.

[0051] The abutment member 132 is provided to facilitate the compressible member 131 to evenly apply force to the first workpiece W1, thereby achieving smooth separation of the workpiece from the tool.

[0052] The second workpiece W2 can be directly placed on any flat surface, but the second workpiece W2 needs to be aligned with the first workpiece W1 in the assembly direction. In order to facilitate the positioning of the second workpiece W2 and further improve the assembly accuracy, in some embodiments of the present invention, see Figure 6 The tool 1 may further include a base plate 14 and a movable stage 15 for carrying the second workpiece W2 , wherein the movable stage 15 is configured to be movable relative to the base plate 14 so as to align the first workpiece W1 with the second workpiece W2 in the assembly direction.

[0053] The movable stage 15 may also be roughly plate-shaped and disposed on the upper surface of the bottom plate 14. The bottom plate 14 may be arranged to be stationary. The movable stage 15 may move on the upper surface of the bottom plate 14. The second workpiece W2 may be placed on the upper surface of the movable stage 15, whereby the position of the second workpiece W2 relative to the first workpiece W1 may be adjusted by adjusting the position of the movable stage 15.

[0054] As an alternative to manually dragging the second workpiece W2 to adjust its position, the position of the second workpiece W2 is precisely adjusted by utilizing the mobility of the movable stage 15 to ensure precise alignment of the first workpiece W1 and the second workpiece W2 in the assembly direction, thereby improving assembly accuracy. In addition, contamination and damage to the second workpiece W2 caused by directly dragging the second workpiece W2 is also avoided.

[0055] The shape and size of the movable carrier 15 can be adjusted according to the shape and size of the workpiece to be suitable for the assembly of different products.

[0056] In order to facilitate the control of the displacement of the movable platform, in some embodiments of the present invention, the movable platform 15 is movably connected to the bottom plate 14. As an example, the movable platform 15 can be connected to the bottom plate through a slider and a slide rail mechanism.

[0057] See also Figure 6 , the tool 1 may include a slider and a slide rail mechanism 16, wherein the slide rail portion may be disposed on the upper surface of the base plate 14, and the slider portion may be disposed on the lower surface of the movable platform 15. Alternatively, it may be the other way around, that is, the slider portion may be disposed on the upper surface of the base plate 14, and the slide rail portion may be disposed on the lower surface of the movable platform 15. The coordinated use of the slider and the slide rail may reduce friction during movement, ensure smooth movement of the movable platform 15 and accuracy of position adjustment, and provide convenience for positioning operations. Moreover, the slider and the slide rail mechanism provide a stable mechanical connection, ensuring that the movable platform 15 will not shake or deflect during movement, thereby ensuring the stability of the overall structure, and even in the case of a heavy workpiece, it can provide stable support through a strong load-bearing capacity.

[0058] It is understandable that other methods may be used to replace the slider and the slide rail mechanism, as long as the movable platform can be displaced relative to the base plate.

[0059] In order to prevent the second workpiece W2 from being displaced on the movable stage 15, especially from being displaced during the adjustment of the movable stage 15, in some embodiments of the present invention, see Figure 6 A second accommodating portion 17 for accommodating the second workpiece W2 may be formed on the movable stage 15. The second accommodating portion 17 may be formed to have a shape corresponding to at least a portion of the second workpiece W2.

[0060] like Figure 6 As shown, the second accommodating portion 17 may be a recess formed on the upper surface of the movable stage 15, in which at least the lower portion of the second workpiece W2 may be accommodated. The second accommodating portion 17 may restrict the second workpiece W2 on the movable stage 15 during the movement of the movable stage 15, so as to prevent the second workpiece W2 from shifting relative to the movable stage 15. Thus, the first workpiece W1 and the second workpiece W2 may be aligned in the assembly direction by simply adjusting the position of the movable stage 15.

[0061] In the process of the driving part 12 driving the first accommodating part 11 to move along the assembly direction, the deflection of the first accommodating part 11 relative to the assembly direction will directly affect the alignment accuracy of the two workpieces. In order to avoid such deflection, in some embodiments of the utility model, the tool 1 may further include a guide assembly 18 for guiding the first accommodating part 11 to move along the assembly direction. The guide assembly 18 can limit the movement of the first accommodating part 11 in the assembly direction, making the assembly operation simpler, easier to perform and ensuring the assembly accuracy.

[0062] Regarding the implementation of the guide assembly 18, in some embodiments of the present invention, the guide assembly 18 may include a guide column 181 formed on one of the base plate 14 and the first accommodating portion 11 and a guide hole 182 formed on the other of the base plate and the first accommodating portion 11 and matching the guide column.

[0063] like Figure 6As shown, the guide post 181 can be formed on the base plate 14, and the guide hole 182 can be formed on the first receiving portion 11. The guide post 181 and the guide hole 182 are clearance-fitted to allow the guide post 18 to move through the guide hole 182. In the embodiment shown in the figure, the guide post 181 gradually enters the guide hole 182 after the assembly operation begins. Therefore, the positions of the guide post 181 and the guide hole 182 relative to each other represent whether the first workpiece W1 and the second workpiece W2 are aligned in the assembly direction. The operator can use this as a basis for calibrating the tool 1. Once it is found that the guide post 181 cannot be inserted into the guide hole 182, it means that the tool 2 needs to be calibrated before it can continue to be used.

[0064] According to some embodiments of the present invention, the tool 1 may further include a base 19. The first receiving portion 11, the driving portion 12, and the separating portion 13 may be connected to the base 19. Figure 1 The base 19 can be in the form of a plate-like member and can be fixed to other stable supporting structures by connecting members such as bolts, for example, it can be fixed to other workbenches, racks, walls of buildings, etc. In other embodiments not shown, the base 19 itself can be formed as a frame-type structure that can be independently placed on a flat surface such as the surface of a workbench. The specific form of the base 19 can be designed according to the circumstances of the application, and the utility model does not limit this. The base 19 is configured to have sufficient strength to withstand the weight of the various components connected thereto and the first workpiece W1, and to absorb and resist vibration and impact forces from the drive unit when the drive unit 12 is working.

[0065] In some embodiments of the present invention, see Figure 6 and Figure 7 The base 19 can be connected to the bottom plate 14 as a whole to provide a more stable support for the entire assembly operation.

[0066] According to an embodiment of the utility model, the specific implementation of the drive unit 12 can be flexibly selected. Specifically, the drive unit 12 can be driven in an automatic manner, or can be formed to be driven manually. In the automatic drive implementation, the drive unit 12 can be configured to drive the first accommodating portion 11 to move along the assembly direction according to the drive signal. In some embodiments of the utility model, the drive unit 12 may include a motor, and the received electrical signal controls the movement direction and speed of the first accommodating portion 11. In other embodiments of the utility model, a hydraulic or pneumatic system can be used instead of a motor system.

[0067] In the manual drive implementation, see Figure 6 and Figure 7The driving portion 12 may include a handle 121, and the handle 121 may be configured to drive the first accommodating portion 11 to move along the assembling direction by rotating.

[0068] Specifically, in some embodiments of the present invention, see Figure 6 and Figure 7 The driving part 12 may be connected to the base 19 and may further include a transmission rod 122 and a connecting piece 123 connecting the handle 121 and the transmission rod 122. One end of the handle 121 is used for the operator to grasp in order to apply the assembly force, and the other end of the handle 121 always abuts against one end of the transmission rod 122, and the handle 121 is rotatably connected to the base 19 at a position between the two ends and close to the transmission rod 122. The transmission rod 122 may be connected to the base 19 in a manner that it can move in the vertical direction. Figure 6 As shown, the transmission rod 122 is connected to the base 19 through a sleeve 124. The transmission rod 122 can move in the vertical direction through the sleeve 124, and the sleeve 124 also limits the transmission rod 122 so that it cannot move in other directions. The sleeve 124 is fixedly connected to the base 19.

[0069] contrast Figure 6 and Figure 7 ,exist Figure 6 In the embodiment, the handle 121 is at the highest position, the first workpiece W1 has been placed in the first receiving portion 11, but the assembly operation has not yet started; Figure 7 In the figure, the handle 121 has been rotated downward to a lower position, and the first workpiece W1 and the second workpiece W2 have been assembled together by press fitting. The two ends of the connecting member 123 are respectively hinged to the handle 121 and the transmission rod 122, so as to allow the rotational movement of the handle 121 to be converted into the linear movement of the transmission rod 122 in the vertical direction while keeping the handle 121 against the transmission rod 122. The other end of the transmission rod 122 is fixedly connected to the first accommodating portion 11, so that the first accommodating portion 11 can be pushed to move in the vertical direction, thereby realizing the assembly operation.

[0070] In order to avoid the first accommodating portion 11 and the second accommodating portion 17 from colliding with each other when the first workpiece W1 and the second workpiece W2 are pressed together, thereby causing damage to the tool 1 and the workpiece and generating excessive noise, in some embodiments of the present invention, see Figure 7 The tool 1 may further include a buffer member 20 disposed on either the first accommodating portion 11 or the movable platform 15 , and the buffer member 20 is used to provide buffering when the first accommodating portion 11 collides with the movable platform 15 .

[0071] The buffer member 20 may be provided on at least one of the lower surface of the first accommodation portion 11 and the upper surface of the second accommodation portion 17 and protrude vertically from the provided surface. The buffer member 20 may be made of an elastic material, for example, may be made of rubber.

[0072] In some embodiments of the present invention, the first workpiece W1 may be a shielding cover, and the second workpiece W2 may be a PCB.

[0073] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
