pressing device

Abstract

The application discloses a pressing device, which comprises a support, a bearing platform, a lifting piece and a pressing piece. The bearing platform is arranged on the support and is configured to bear a workpiece, and the workpiece is stacked with materials. The lifting piece is arranged on the support in a vertically movable manner. The pressing piece is arranged on the lifting piece in a vertically movable manner and is located above the bearing platform. The lifting piece drives the pressing piece to move vertically relative to the support, so that the pressing piece is stacked on the materials. The pressing piece can move vertically relative to the lifting piece freely, so that the pressing piece can press the materials to the workpiece by using its own gravity. The pressing piece uses its own weight to apply force to the materials, and no external energy source is needed. When the weight of the pressing piece is constant, the pressing force of the pressing piece on the materials is also constant, and the risk of pressure deviation caused by fluctuation of the external energy source can be reduced. In the processing of batch products, the same pressing piece is used to press the materials to the workpiece one by one to obtain multiple products. The pressing force of the pressing piece on the materials is consistent, so that the quality control of the multiple products is stable.

Description

Technical Field

[0001] This application belongs to the field of electronic manufacturing technology, and specifically relates to a pressing device. Background Technology

[0002] In the packaging and securing of electronic products (such as components for mobile phones and tablets), polyester film is typically used to adhere one side of the workpiece to protect it. In related technologies, a power source (such as pneumatic, hydraulic, or electric) is usually employed to apply force to the polyester film against the workpiece surface via a pressure component, ensuring a stable, bubble-free, and warp-free adhesion. However, the power source is susceptible to energy fluctuations (such as gas / liquid volume fluctuations, voltage instability, etc.), which can easily lead to deviations in pressure, affecting the consistency of pressure application and consequently causing product quality control instability. Utility Model Content

[0003] This application provides a pressure-reducing device designed to improve the problem of unstable product quality control caused by deviations in pressure magnitude.

[0004] This application provides a pressing device, including a support, a bearing platform, a lifting member, and a pressing member; the bearing platform is disposed on the support and configured to bear workpieces, on which materials are stacked; the lifting member is vertically movable on the support; the pressing member is vertically movable on the lifting member and located above the bearing platform; the lifting member can drive the pressing member to move vertically relative to the support, so that the pressing member is stacked on the materials; the pressing member can move freely vertically relative to the lifting member, so that the pressing member can press the materials onto the workpieces by its own weight.

[0005] In the aforementioned pressing device, the lifting component moves vertically relative to the support, thereby causing the pressing component to move vertically relative to the supporting platform. This adjusts the vertical position of the pressing component, allowing it to be placed on top of the material. The pressing component can also move vertically relative to the lifting component, allowing it to descend under its own weight, pressing the material onto the workpiece. This causes the material to adhere to the workpiece, resulting in the desired product. The pressure exerted by the pressing component on the material is equal to the weight of the pressing component itself. By adjusting the weight of the pressing component, the pressure applied to the material can be adjusted, making the pressure controllable and suitable for different products.

[0006] The pressing component applies force to the material using its own weight, requiring no external energy. Since the weight of the pressing component remains constant, the pressure exerted on the material remains constant, reducing the risk of pressure deviations caused by fluctuations in external energy. In batch processing, the same pressing component is used to press the material onto the workpiece one by one to obtain multiple products. The consistent pressure exerted by the pressing component on the material ensures stable quality control across multiple products.

[0007] In some embodiments, the pressing device further includes a first guide and a second guide. The first guide is disposed on the bracket and connected to the lifting member, and is used to guide the lifting member to move vertically relative to the bracket. The second guide is disposed on the lifting member and connected to the pressing member, and is used to guide the pressing member to move vertically relative to the lifting member.

[0008] Guided by the first and second guide members, the movement path of the lifting and pressing components is restricted to the vertical direction, which is conducive to the smooth vertical movement of the lifting and pressing components and can also prevent the lifting and pressing components from shifting horizontally during the movement, so as to ensure that the pressing components can be accurately and reliably stacked on the materials after the movement.

[0009] In some embodiments, the first guide member is configured as a vertically extending first guide rod, which is fixed to the bracket and passes through the lifting member, allowing the lifting member to move along the first guide rod; the second guide member is configured as a vertically extending second guide rod, which passes through the lifting member and is movable relative to the lifting member; the pressing member includes a counterweight and a pressing head, the counterweight being connected to the top end of the second guide rod and the pressing head being fixed to the bottom end of the second guide rod; the lifting member can carry the counterweight to drive the pressing member to move vertically relative to the bracket; when the pressing head is stacked on the material, the lifting member and the counterweight are spaced apart, and the counterweight can apply force to the pressing head, causing the pressing head to press the material down onto the workpiece.

[0010] Both the first and second guide members are set as guide rods to facilitate the movement and guidance of the lifting and pressing parts.

[0011] In some embodiments, the first guide member is configured as a vertically extending first guide rail, the first guide rail is fixed to the bracket, and the lifting member is slidably connected to the first guide rail; the second guide member is configured as a vertically extending second guide rail, the second guide rail is fixed to the lifting member, and the pressure member is slidably connected to the second guide rail.

[0012] Both the first and second guide components are designed as guide rails, resulting in a simple structure and easy assembly.

[0013] In some embodiments, the pressing device further includes a positioning member fixed to the first guide rod, the positioning member being configured to abut against the lifting member when the lifting member and the counterweight are spaced apart.

[0014] When the lifting component and the counterweight are spaced apart, the counterweight can apply downward pressure to the material through the pressure head. The positioning component positions the lifting component to limit the end point of the lifting component's downward stroke, ensuring that the position of the pressure component relative to the lifting component is consistent each time the pressure component presses down on the material, thus ensuring the consistency of multiple products.

[0015] In some embodiments, the pressure member includes a mounting frame, a counterweight, and a pressure head. The mounting frame is connected to the lifting member, the counterweight is detachably connected to the upper part of the mounting frame, and the pressure head is connected to the lower part of the mounting frame and is used to press material down onto the workpiece.

[0016] The pressure component is detachably connected to the counterweight via a mounting bracket, allowing for the replacement of counterweights of different weights. This alters the pressure exerted by the pressure component on the material, making the pressing device suitable for various materials and workpieces.

[0017] In some embodiments, a flexible element is provided on the side of the pressure head facing the support platform, and the flexible element can elastically deform when pressing against the material.

[0018] When the flexible component presses against the material and workpiece, it undergoes elastic deformation through compression to adapt to the surface shape of the material. This allows the flexible component to press the material against the workpiece softly and stably, reducing the formation of air bubbles when the material adheres to the workpiece. Furthermore, compared to rigid contact, the flexible component provides gentler pressure to the material, preventing damage to both the material and workpiece when pressing against them, thus protecting both.

[0019] In some embodiments, the pressure member further includes a ball bearing, which is embedded between the mounting frame and the pressure head; a plurality of elastic elements are connected between the mounting frame and the pressure head, and the plurality of elastic elements are distributed around the outer periphery of the ball bearing; when the pressure head presses against the material, it can tilt relative to the mounting frame around the ball bearing and elastically compress the elastic elements.

[0020] If the workpiece and material are set at an angle, when the pressure head presses against the material, the pressure head can tilt relative to the mounting frame around the ball so that the lower surface of the pressure head fits against the upper surface of the material. This helps to distribute the pressure applied by the counterweight through the pressure head evenly on the upper surface of the material.

[0021] In some embodiments, the pressing device further includes a drive member disposed on the bracket and connected to the lifting member, the drive member being configured to drive the lifting member to move vertically relative to the bracket.

[0022] The drive unit provides an upward pulling force when the lifting component rises to improve the automation level of the pressing device and reduce the labor intensity of the operator; the drive unit provides an upward pulling force when the lifting component falls to prevent the lifting component and pressing component from falling rapidly under the action of gravity and impacting and damaging materials and workpieces.

[0023] In some embodiments, the carrying platform is connected to a lifting member, which is located on a support and is used to drive the carrying platform to move vertically relative to the support.

[0024] The lifting mechanism drives the carrying platform to move vertically, thereby changing the vertical height of the carrying platform and the workpieces on it, which facilitates the processing of workpieces and materials to obtain products, and the unloading of products.

[0030] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] In the description of the embodiments of this application, the technical terms "first", "second", etc. are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0035] In related technologies, a power source (such as pneumatic, hydraulic, or electric) is typically used to apply force to the polyester film towards the workpiece surface via a pressure component, pressing the polyester film against the workpiece to ensure a stable, bubble-free, and warp-free adhesion. However, the power source is susceptible to energy fluctuations (such as gas / liquid volume fluctuations, voltage instability, etc.), which can easily lead to deviations in pressure magnitude, affecting the consistency of pressure application and consequently causing product quality control instability.

[0036] An embodiment of this application provides a pressing device, including a support, a bearing platform, a lifting member, and a pressing member; the bearing platform is disposed on the support and configured to bear workpieces, on which materials are stacked; the lifting member is vertically movable on the support; the pressing member is vertically movable on the lifting member and located above the bearing platform; the lifting member can drive the pressing member to move vertically relative to the support, so that the pressing member is stacked on the materials; the pressing member can move freely vertically relative to the lifting member, so that the pressing member can press the materials onto the workpieces by its own weight.

[0037] In the aforementioned pressing device, the lifting component moves vertically relative to the support, causing the pressing component to move vertically relative to the supporting platform. This adjusts the vertical position of the pressing component, allowing it to be stacked on top of the material. The pressing component can move vertically relative to the lifting component, allowing it to descend under its own weight, pressing the material onto the workpiece. This causes the material to adhere to the workpiece, resulting in the desired product. The pressure exerted by the pressing component on the material is equal to its own weight. By adjusting the weight of the pressing component, the pressure applied to the material can be adjusted, making the pressure controllable and suitable for different products. The pressing component applies force to the material using its own weight, requiring no external energy. Since the weight of the pressing component remains constant, the pressure exerted on the material remains constant, reducing the risk of pressure deviations caused by fluctuations in external energy. In batch processing, the same pressing component is used to press material onto workpieces one by one to obtain multiple products. The consistent pressure exerted by the pressing component on the material ensures stable quality control across multiple products.

[0038] The embodiments of this application will be further described below with reference to the accompanying drawings. Unless otherwise specified, the various embodiments in this application can be combined with each other.

[0039] Please see Figure 1 and Figure 2 This application provides a pressing device 100 for pressing down on materials stacked on a workpiece, causing the material to adhere to the workpiece to obtain the desired product (not shown). Exemplarily, the material is a polyester film, the workpiece is a mobile phone case, and the product is a mobile phone case with the polyester film attached. Alternatively, the material can be a mobile phone screen, the workpiece can be a mobile phone body, and the pressing device 100 is used to press the mobile phone screen against the mobile phone body, which facilitates bubble-free curing of the optical adhesive between the mobile phone screen and the mobile phone body, ensuring a satisfactory fit between the mobile phone screen and the mobile phone body.

[0040] The pressing device 100 includes a support 10, a bearing platform 20, a lifting member 30, and a pressing member 40. Both the bearing platform 20 and the lifting member 30 are mounted on the support 10. The bearing platform 20 is configured to support workpieces, on which materials are stacked. The pressing member 40 is located above the lifting member 30 and above the bearing platform 20. The lifting member 30 can move vertically relative to the support 10, and thus moves the pressing member 40 vertically relative to the support 10 as well, changing the vertical position of the pressing member 40 so that it can be stacked on top of the materials. The pressing member 40 can move freely vertically relative to the lifting member 30. After the pressing member 40 is stacked on top of the materials, the force on the pressing member 40 is separated from the force on the lifting member 30, limiting the force on the pressing member 40 to its own weight. Therefore, the pressing member 40 presses the materials onto the workpieces under its own weight; that is, the pressure exerted by the pressing member 40 on the materials is the weight of the pressing member 40 itself.

[0041] Understandably, pressing the material down onto the workpiece by the pressure component 40 allows the material to adhere to the workpiece and obtain the desired product, and the adhered product is less prone to bubbles or warping.

[0042] The pressing component 40 applies force to the material using its own weight, requiring no external energy. Since the weight of the pressing component 40 remains constant, the pressure exerted on the material remains constant, reducing the risk of pressure deviations caused by fluctuations in external energy sources. For example, fluctuations in the air supply pressure of a cylinder can cause pressure changes, or aging seals in a hydraulic cylinder can lead to oil leaks, causing fluctuations in fluid volume and thus pressure changes. In batch processing, the same pressing component 40 presses the material onto the workpiece one by one to obtain multiple products. The consistent pressure exerted by the pressing component 40 on the material ensures stable quality control across multiple products.

[0043] In some embodiments, the support platform 20 is connected to a lifting member 21, which is mounted on the bracket 10 and used to drive the support platform 20 to move vertically relative to the bracket 10, thereby changing the vertical height of the support platform 20 and the workpiece and material on the support platform 20, so that the workpiece can move between the processing position and the unloading position. For example, when the workpiece is in the processing position, the pressure member 40 can press the material onto the workpiece by its own gravity to process the desired product; when the workpiece is in the unloading position, the support platform 20 can dock with the production line, allowing the product to be output through the production line for unloading.

[0044] The lifting component 21 includes multiple cylinders, which act simultaneously on the support platform 20 to quickly drive the support platform 20 to rise and fall.

[0045] Please see Figure 2 and Figure 3In some embodiments, the support platform 20 is provided with multiple support members 22, the outer surface of which is covered with urethane (not shown). Each support member 22 is used to support a workpiece. When the pressure member 40 presses the material onto the workpiece, the workpiece is pressed against the urethane. Compared to rigid contact between the support member 22 and the workpiece, contact with the workpiece through the urethane can buffer the impact force of the workpiece on the support member 22, preventing the workpiece from being damaged by rigid impact. The urethane is coated on the outer surface of the support member 22 to prevent the workpiece from being scratched or damaged.

[0046] Please see Figure 1 and Figure 2 The pressing device 100 also includes a driving member 11, which is disposed on the bracket 10 and connected to the lifting member 30. The driving member 11 is used to drive the lifting member 30 to move vertically relative to the bracket 10, thereby providing power for the vertical movement of the lifting member 30. For example, the driving member 11 is a cylinder.

[0047] When the lifting component 30 rises, the drive component 11 provides an upward pulling force to improve the automation level of the pressing device 100 and reduce the labor intensity of the operator; when the lifting component 30 falls, the drive component 11 provides an upward pulling force to prevent the lifting component 30 and the pressing component 40 from falling rapidly under the action of gravity and impacting and damaging the materials and workpieces.

[0048] Please see Figure 1 In some embodiments, the pressing device 100 includes one or more lifting members 30 and pressing members 40, each pressing member 40 being connected to a lifting member 30, and each driving member 11 being connected to a lifting member 30, so as to adjust the position of the plurality of pressing members 40 respectively. Please refer to Figure 2 In other embodiments, the pressing device 100 includes a lifting member 30 and multiple pressing members 40, all of which are connected to the lifting member 30, so that the driving member 11 can move by driving the lifting member 30 to drive the multiple pressing members 40 to move simultaneously.

[0049] Please see Figure 1 and Figure 3 The pressing component 40 includes a mounting frame 41, a counterweight 42, and a pressing head 43. The mounting frame 41 is connected to the lifting component 30. The counterweight 42 is detachably connected to the upper part of the mounting frame 41. The pressing head 43 is connected to the lower part of the mounting frame 41 and is used to press materials down onto the workpiece.

[0050] The pressure component 40 is detachably connected to the counterweight 42 via the mounting bracket 41, so as to replace the counterweight 42 with different weights, thereby changing the pressure of the pressure component 40 on the material, so that the pressing device 100 can be used for different materials and workpieces.

[0051] For example, the counterweight 42 is a weight. By adding or removing the weights stacked sequentially, or by replacing the weights with weights of different masses, the weight of the pressure member 40 can be changed, thereby adjusting the pressure exerted by the pressure member 40 on the material. The mounting bracket 41 extends upward with two insertion posts 411. The counterweight 42 is inserted into the insertion posts 411 so that the insertion posts 411 position the counterweight 42, thereby limiting the horizontal displacement of the counterweight 42.

[0052] In some embodiments, the pressure head 43 has a flexible element (not shown) on the side facing the support platform 20. This flexible element can elastically deform when pressing against the material to adapt to the surface shape of the material, allowing it to gently and stably press the material against the workpiece, reducing the formation of air bubbles when the material adheres to the workpiece. Understandably, the elastic deformation of the flexible element adapts to minor unevenness on the material surface, ensuring that the pressure applied by the counterweight 42 through the pressure head 43 is evenly distributed across the contact surface between the material and the workpiece. This reduces air bubbles caused by insufficient local pressure when the material adheres to the workpiece, resulting in a smoother and more secure fit between the material and the workpiece, meeting product quality requirements. Furthermore, compared to rigid contact, the flexible element provides gentler pressure to the material, preventing damage to both the material and the workpiece when pressing against it, thus protecting both.

[0053] In some embodiments, the flexible element includes, but is not limited to, urethane, sponge or rubber, and is wrapped around the outer surface of the pressure head 43 to prevent materials and workpieces from being scratched or damaged.

[0054] Please see Figure 4 In some embodiments, the pressure member 40 further includes a ball 44, which is embedded between the mounting bracket 41 and the pressure head 43. Exemplarily, the upper end of the ball 44 is embedded in the mounting bracket 41, and the lower end of the ball 44 is embedded in the pressure head 43, so that the ball 44 can roll relative to the mounting bracket 41 and the pressure head 43.

[0055] Multiple elastic elements 45 are connected between the mounting frame 41 and the pressure head 43, and the multiple elastic elements 45 are distributed around the outer periphery of the ball 44. The ball 44 is located at the center of the mounting frame 41 and the pressure head 43. When the pressure member 40 presses down on the material, the elastic elements 45 are elastically compressed under force, and the ball 44 can transmit the pressure of the counterweight 42 to the pressure head 43 and act on the material.

[0056] When the workpiece and material are tilted, when the pressure head 43 presses against the material, the pressure head 43 can tilt relative to the mounting bracket 41 around the ball bearing 44, so that the lower surface of the pressure head 43 is in contact with the upper surface of the material. This helps to evenly distribute the pressure applied by the counterweight block 42 through the pressure head 43 onto the upper surface of the material. At this time, the elastic element 45 is elastically compressed. When the pressure head 43 leaves the material, the elastic element 45 rebounds, making the pressure head 43 horizontal. The elastic element 45 includes four springs, which are located at the four corners of the pressure head 43.

[0057] In some embodiments, the pressure head 43 is provided with a pressure sensor 431, which is used to sense the pressure of the pressure member 40 on the material in order to monitor the pressure of the pressure member 40 on the material.

[0058] Please see Figure 1 and Figure 2 In some embodiments, the pressing device 100 further includes a first guide 50 and a second guide 60. The first guide 50 is disposed on the bracket 10 and connected to the lifting member 30, and is used to guide the lifting member 30 to move vertically relative to the bracket 10. The second guide 60 is disposed on the lifting member 30 and connected to the pressing member 40, and is used to guide the pressing member 40 to move vertically relative to the lifting member 30.

[0059] Guided by the first guide 50 and the second guide 60, the movement path of the lifting component 30 and the pressing component 40 is restricted to the vertical direction, which is conducive to the smooth vertical movement of the lifting component 30 and the pressing component 40, and can also prevent the lifting component 30 and the pressing component 40 from horizontally shifting during the movement, so as to ensure that the pressing component 40 can be accurately and reliably stacked on the material after the movement.

[0060] Please see Figure 1 In some embodiments, the first guide member 50 is configured as a vertically extending first guide rail 51, the first guide rail 51 being fixed to the bracket 10, and the lifting member 30 being slidably connected to the first guide rail 51. The second guide member 60 is configured as a vertically extending second guide rail 61, the second guide rail 61 being fixed to the lifting member 30, and the pressing member 40 being slidably connected to the second guide rail 61.

[0061] Please see Figure 2 In some embodiments, the first guide member 50 is configured as a vertically extending first guide rod 52, which is fixed to the bracket 10 and passes through the lifting member 30, allowing the lifting member 30 to move along the first guide rail 51. The second guide member 60 is configured as a vertically extending second guide rod 62, which passes through the lifting member 30 and is movable relative to the lifting member 30. The mounting bracket 41 is fixedly connected to the top end of the second guide rod 62, so that the counterweight 42 is detachably mounted on the top end of the second guide rod 62 via the mounting bracket 41, and the pressure head 43 is fixedly mounted on the bottom end of the second guide rod 62.

[0062] The lifting component 30 can support the counterweight 42 to drive the pressing component 40 to move vertically relative to the support 10. When the pressing component 40 moves to the pressing head 43 to place the material, the lifting component 30 and the counterweight 42 are separated. The counterweight 42 can apply force to the pressing head 43 through the second guide rod 62, causing the pressing head 43 to press the material down onto the workpiece. When the pressing component 40 has not moved to the pressing head 43 to place the material, the lifting component 30 supports the counterweight 42 to drive the counterweight 42, the second guide rod 62 and the pressing head 43 to move vertically together.

[0063] Please see Figure 2 The first guide member 50 includes four first guide rods 52, which are located at the four corners of the lifting member 30 to stably support the lifting member 30 and prevent the lifting member 30 from tilting.

[0064] Please see Figure 2 and Figure 3 In some embodiments, the lifting component 30 includes a top plate 31, a bottom plate 32, and a connecting rod 33 connecting the top plate 31 and the bottom plate 32. The driving component 11 is connected to the top plate 31. A first guide rod 52 passes through the top plate 31, and a second guide rod 62 passes through the bottom plate 32. The top plate 31 and the bottom plate 32 respectively connect the first guide rod 52 and the second guide rod 62, allowing for partitioned arrangement of the first guide rod 52 and the pressure component 40, preventing interference between the pressing device 100 and the lifting device during operation. The top plate 31 and the bottom plate 32 are spaced apart, providing space for the installation of the counterweight, allowing the counterweight block 42 to be positioned between the top plate 31 and the bottom plate 32.

[0065] Please see Figure 2 In some embodiments, the pressing device 100 further includes a positioning element 70, which is fixed to the first guide rod 52 and is configured to abut against the lifting element 30 when the lifting element 30 is spaced from the counterweight 42.

[0066] Understandably, when the top plate 31 moves to abut against the positioning element 70, the pressure head 43 is stacked on the material, and the counterweight 42 is spaced apart from the bottom plate 32. At this time, the counterweight 42 can apply downward pressure to the material through the pressure head 43. In the processing of batch products, the positioning element 70 positions the lifting element 30 to limit the end point of the downward stroke of the lifting element 30, ensuring that the position of the pressure element 40 relative to the lifting element 30 is consistent each time it presses down on the material. This ensures the consistency of multiple products and makes the quality control of multiple products stable.

[0067] In some embodiments, the positioning member 70 can also be fixedly disposed on the first guide rail 51 and abut against the lifting member 30 when the pressure head 43 is stacked on the material, so as to position the end point of the downward stroke of the lifting member 30. Figure 1 In the middle, the end of the first guide rail 51 acts as a positioning element 70 to position the end point of the lifting and lowering stroke.

[0068] When in use, the lifting member 30 is driven to move vertically relative to the bracket 10 until the lifting member 30 abuts against the positioning member 70, thus completing the adjustment of the position of the pressing member 40. At this time, the pressing head 43 is placed on the material, and the pressing member 40 can move vertically freely relative to the lifting member 30. The entire weight of the pressing member 40 is applied to the material, so that the material adheres to the workpiece to obtain the desired product.

[0069] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
