Description

Technical Field

[0001] The present invention relates to the technical field of molds, and particularly to a quick-release pressure-holding jig head for a pressure sensor and a pressure-holding device having the same. Background Art

[0002] In the manufacturing process of various intelligent devices, such as smart phones, cameras, tablet computers, and smart bracelets, etc., it is often necessary to press and fix two of the components constituting their structures together flatly with adhesive. For example, it is necessary to press and fix the display screen or the back glass decorative panel of a smart phone flatly with adhesive to its frame housing.

[0003] Conventionally, when pressing and fixing two corresponding components, generally a workpiece fixing seat is set to fix one of the components, and an adhesive layer is provided on the upper surface of one of the corresponding components, and a workpiece pressing jig head for fixing the other component is provided above the corresponding workpiece fixing seat. The workpiece pressing jig head drives the other component fixed thereon to move downward and press onto the corresponding adhesive layer. When the corresponding adhesive layer is heated to a molten state, it can bond the two corresponding components together.

[0004] However, in specific implementation, the downward pressure applied by the corresponding workpiece pressing jig head to the corresponding adhesive layer must be precisely limited. When the downward pressure applied is too large, it is easy to damage and crush the two corresponding components. When the downward pressure applied is too small, the other component fixed thereon cannot closely adhere to the corresponding adhesive layer, resulting in a poor fitting and fixing effect between the two subsequent corresponding components and easily generating defective products.

[0005] Therefore, at present, a pressure sensor is usually provided inside the bottom of the corresponding workpiece pressing jig head to detect the downward pressure applied. When the corresponding workpiece pressing jig head is frequently used, the pressure sensor used will be continuously pushed upward by the reaction force of the applied force, making it easy to break down and need to be frequently replaced. However, since it is provided inside the bottom of the corresponding workpiece pressing jig head, it is necessary to disassemble the entire corresponding workpiece pressing jig head to take it out, which makes the operation troublesome, time-consuming and laborious, greatly increasing the manual disassembly and assembly cost, and making the corresponding workpiece pressing jig head unable to be assembled quickly for emergency use.

[0006] Therefore, based on work experience, the inventor of this patent designed this application to solve the related technical problems. Summary of the Invention

[0061] The quick-release pressure-holding fixture head 1000 of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0062] Embodiment 1

[0063] Refer to Figures 1 to 5As shown, the quick-release pressure-holding fixture head 1000 for a pressure sensor according to an embodiment of the present invention includes a power board 10, a pressure sensor 20, a pressure-relieving member 30, a pressure table 40, and a pressure table supporting member 50 for supporting the pressure table 40.

[0064] Among them, a lifting mechanism (not shown) for driving its up and down movement is provided on the power board 10; the pressure sensor 20 is detachably mounted on the bottom of the power board 10; the pressure-relieving member 30 abuts between the pressure sensor 20 and the pressure table 40; the pressure table supporting member 50 is connected between the power board 10 and the pressure table 40.

[0065] Based on the above, it is clear that in specific implementation, this application is mainly used as the quick-release pressure-holding fixture head 1000 for a pressure sensor.

[0066] During actual operation, in combination with Figure 6 and Figure 7 As shown, two workpieces to be pressed and fixed together are correspondingly installed on a workpiece fixing seat 2000 and the bottom of the pressure table 40, and an adhesive layer is provided on the upper end surface of the workpiece fixed on the corresponding workpiece fixing seat 2000. The lifting mechanism (not shown) drives the power board 10 together with the pressure table 40 to move downward, and the workpiece fixed on the pressure table 40 can be pressed and attached to the adhesive layer on the upper end surface of the workpiece fixed on the workpiece fixing seat 2000. In this way, the pressing and fixing between the two corresponding workpieces can be completed.

[0067] The main improvement of this application is that the traditional workpiece pressing fixture head is disassembled into the power board 10, the pressure sensor 20, the pressure-relieving member 30, the pressure table 40, and the pressure table supporting member 50 for supporting the pressure table 40, and they are fixed together through the above connection relationship.

[0068] On the one hand, the provided pressure sensor 20 is detachably mounted on the bottom of the power board 10. Thus, when it breaks down, it can be directly removed from the bottom of the power board 10 without disassembling the whole application, making the operation simple, time-saving and labor-saving, greatly reducing the manual disassembly and assembly cost, and enabling this application to be installed quickly for emergency use.

[0069] On the other hand, initially, the pressing table 40 is lifted by the pressing table supporting member 50. When the power plate 10 together with the pressing table 40 moves downward until the workpiece fixedly arranged at the bottom of the pressing table 40 fits onto the adhesive layer on the upper end surface of the workpiece fixed on the workpiece fixing seat 2000, the pressing table 40 will not hard press the two corresponding workpieces that are fitted together at this time. When the power plate 10 together with the pressing table 40 continues to move downward, the pressure relief member 30 will be compressed, so that the buffer of the downward pressure can be carried out to play a role of pressure relief, so that the two corresponding workpieces that are fitted together are not easily damaged instantaneously, and the reliability of the application is good.

[0070] Furthermore, the application has strong practicability and good use effect.

[0071] In addition, according to the pressure sensor quick-release pressure-holding jig head 1000 of the above embodiment of the present invention, a card slot 101 is opened upward at the bottom of the power plate 10, and a sensor access port 102 communicating with the card slot 101 is opened on the side surface of the power plate 10; the pressure sensor 20 is detachably clamped in the card slot 101 through the sensor access port 102.

[0072] As described above, it can be foreseen that during the specific implementation of the present application, since the pressure sensor 20 is detachably clamped in the card slot 101 through the sensor access port 102, thus, by reverse operation, that is, the pressure sensor 20 of the present application can also be taken out from the card slot 101 through the sensor access port 102, making its disassembly and assembly really convenient, really time-saving and labor-saving. When it is clamped in the card slot 101 during use, it is not easy to shift, making the use stable and reliable.

[0073] Further, in contrast Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, the present application further includes a sensor fixing member 60; the sensor fixing member 60 is detachably clamped in the card slot 101 through the sensor access port 102, and a cavity 601 penetrating its lower bottom surface is opened on the upper end surface of the sensor fixing member 60, and the pressure sensor 20 is detachably accommodated in the cavity 601.

[0074] Because the size of the simple pressure sensor 20 is relatively small, it is not easy to take and place, so the sensor fixing member 60 is designed to sleeved the pressure sensor 20. When it is pulled out from the card slot 101 through the sensor access port 102, it is convenient to take out the pressure sensor 20 sleeved therein for replacement. By reverse operation, when it is inserted into the card slot 101 through the sensor access port 102, it is convenient to insert the replaced pressure sensor 20 sleeved therein into the card slot 101 for replacement.

[0075] Further, according to an embodiment of the present invention, a wire groove 602 communicating with the cavity 601 is formed on the outer side surface of the sensor fixing member 60, and the wire groove 602 has a wire passing opening 603 penetrating through the upper end surface and / or the lower bottom surface of the sensor fixing member 60.

[0076] Thus, the signal wire connected to the pressure sensor 20 from outside to inside can be placed in the wire groove 602 through the wire passing hole, so that it is integrally disposed inside the sensor fixing member 60. When the sensor fixing member 60 is inserted or pulled out, the signal wire connected to the pressure sensor 20 from outside to inside is not easily broken, making the application more stable and reliable.

[0077] Preferably, in this embodiment, a cavity 601 penetrating through its lower bottom surface is formed near the inner end of the upper end surface of the sensor fixing member 60. A fixing ear 605 is provided on each of the two outer ends of the sensor fixing member 60. Fixing holes 606 facing the inner end of the sensor fixing member 60 are respectively formed on the two fixing ears 605. Threaded holes 104 facing the two fixing holes 606 are respectively formed on both sides of the sensor access opening 102. The sensor fixing member 60 is fixed to the power board 10 by screwing fastening bolts into the fixing holes 606 and the threaded holes 104 at corresponding positions, so that its inner end extends into the card slot 101 through the sensor access opening 102.

[0078] In this way, the sensor fixing member 60 has good fixing performance, so that the pressure sensor 20 sleeved inside it has good fixing performance and is not easily displaced after being fixed.

[0079] Furthermore, continue to compare Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, the pressure relief member 30 includes a guide post 301 and a pressure relief spring 302;

[0080] Wherein, an outer wall of the guiding column 301 is provided with a flange 3011 around its upper end in an outer ring shape, so that the guiding column 301 is separated into an upper pressing part 301a and a lower guiding part 301b; the upper pressing part 301a extends into the cavity 601 and abuts against the lower bottom surface of the pressure sensor 20; a sliding port 604 facilitating the upper pressing part 301a to slide out of the cavity 601 is formed at a lower part of an inner end of the sensor fixing member 60; the flange 3011 is located at a lower part of the sensor fixing member 60; a guiding hole 401 into which a lower end of the lower guiding part 301b extends is formed downward on an upper end surface of the pressing table 40, and a limiting gap for limiting a descending stroke of the lower guiding part 301b is provided between a bottom of the guiding hole 401 and a lower end of the lower guiding part 301b; the slow-pressure spring 302 is sleeved outside the lower guiding part 301b, an upper end thereof abuts against a lower bottom surface of the flange 3011, and a lower end thereof abuts against an upper end surface of the pressing table 40;

[0081] At the initial stage, the pressing table 40 is lifted by a pressing table supporting member 50 connected to the power plate 10, the slow-pressure spring 302 is in a natural state, and a certain slow-pressure gap is provided between an upper end surface of the flange 3011 and a lower bottom surface of the sensor fixing member 60, and the slow-pressure gap is equal to the limiting gap.

[0082] When the power plate 10 together with the pressing table 40 moves downward until a workpiece fixedly arranged at a bottom of the pressing table 40 just fits onto an adhesive layer on an upper end surface of a workpiece fixed on the workpiece fixing seat 2000, the slow-pressure gap still exists. When the power plate 10 together with the pressing table 40 continues to move downward, the slow-pressure gap will gradually become smaller. During this process, the upper pressing part 301a of the guiding column 301 will exert an upward reaction force on the pressure sensor 20. When a corresponding upward reaction force detected by the pressure sensor 20 reaches a preset value, it will transmit a signal to the main control system, and the corresponding main control system will issue an instruction to control the lifting mechanism to stop working, so as to drive the power plate 10 to drive the pressing table 40 to stop making a downward pressing movement.

[0083] Moreover, when the power plate 10 together with the pressing table 40 moves downward until a workpiece fixedly arranged at a bottom of the pressing table 40 fits onto an adhesive layer on an upper end surface of a workpiece fixed on the workpiece fixing seat 2000, the pressing table 40 will not hard-press the two workpieces that are adhered together. When the slow-pressure gap gradually becomes smaller, the provided slow-pressure member 30 can play a slow-pressure role. When a lower end of the lower guiding part 301b abuts against a bottom of the guiding hole 401, it will not continue to move downward, so that the present application also has a pressure-holding function and will not always press the two workpieces that are adhered together through the pressing table 40, making it really not easy to damage the two corresponding workpieces that need to be pressed and fixed, and making the present application really reliable in use.

[0084] And when it is necessary to replace the pressure sensor 20, the sensor fixing member 60 is directly pulled out. The upper pressing portion 301a of the guiding column 301 is restricted by the flange 3011 and thus remains stationary. The sliding opening 604 of the sensor fixing member 60 will slide away from the upper pressing portion 301a of the guiding column 301. That is, after the upper pressing portion 301a of the guiding column 301 is inserted into the cavity 601 of the sensor fixing member 60, it does not affect the insertion and extraction of the sensor fixing member 60, making the sensor fixing member 60 of the present application reliable in use.

[0085] Furthermore, in specific implementation, continue to refer to Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, the present application further includes a locking block 70 that facilitates the disassembly and assembly of the sensor fixing member 60 and the pressure sensor 20 therein;

[0086] Wherein, a bayonet 3012 is circumferentially cut near the lower end of the outer wall of the lower guiding portion 301b; a locking opening 402 facing the lower guiding portion 301b is formed on the side surface of the pressing table 40; the locking block 70 can be taken and inserted into the locking opening 402, and a U-shaped clip 701 facing the lower guiding portion 301b and adapted to be inserted into the bayonet 3012 to lock and fix the guiding column 301 is provided at its inner end;

[0087] Thus, in implementation, refer to Figure 5 and refer to Figure 6 and Figure 7 As shown, the power plate 10 together with the pressing table 40 moves downward so that the workpiece fixed at the bottom of the pressing table 40 fits onto the adhesive layer on the upper end surface of the workpiece fixed on the workpiece fixing seat 2000. When the power plate 10 together with the pressing table 40 continues to move downward, when the guiding column 301 is pressed downward until its lower end abuts against the bottom of the guiding hole 401 and the buffer spring 302 is in a compressed state, the bayonet 3012 circumferentially cut near the lower end of the outer wall of the lower guiding portion 301b will be directly opposite to the U-shaped clip 701. At this time, the locking block 70 can be pushed inward to clamp the U-shaped clip 701 outside the bayonet 3012 circumferentially cut near the lower end of the outer wall of the lower guiding portion 301b.

[0088] In this way, the guide post 301 is fixed, and the telescopic spring is kept in a compressed state. When the power plate 10 moves upward and resets to the initial state, the pressure relief gap is restored, and the guide post 301 remains fixed. During this process, the telescopic spring cannot push up the guide post 301, so that the upper end of the upward pressing part 301a of the guide post 301 does not exert a force on the pressure sensor 20. At this time, the sensor fixing member 60 together with the pressure sensor 20 sleeved therein can be withdrawn from the card slot 101 through the sensor access port 102 for replacement. During the withdrawal process, no external force is applied to its outer surface, making the withdrawal truly time-saving and labor-saving, and enabling the quick removal of the pressure sensor 20.

[0089] Furthermore, in specific implementation, according to an embodiment of the present invention, the pressing table 40 includes a workpiece pressing plate 40a, a lower fixing plate 40b, a heat insulation plate 40c, and an upper fixing plate 40d that are fixedly attached to each other in sequence from bottom to top.

[0090] Among them, a guide hole 401 is opened downward on the upper end surface of the upper fixing plate 40d, a locking port 402 is opened inward on the side surface of the upper fixing plate 40d, and a plurality of positioning posts 403 are evenly protruded upward on the peripheral edge of the upper end surface of the upper fixing plate 40d; a plurality of positioning holes 103 adapted to insert the corresponding positioning posts 403 are evenly opened upward on the peripheral edge of the lower bottom surface of the power plate 10.

[0091] Thus, by providing the positioning posts 403 and the positioning holes 103 into which the positioning posts 403 are inserted with interference fit, the power plate 10 and the pressing table 40 can move precisely in the up and down directions and are not easily displaced circumferentially, making the use effect of the present application better.

[0092] Moreover, according to an embodiment of the present invention, the pressing table supporting member 50 is formed in an L shape, and there are a plurality of them, and they are evenly fixed to the peripheral edge of the power plate 10 downward through fixing bolts and other members; the lower parts of the plurality of pressing table supporting members 50 all abut against the bottom peripheral edge of the upper fixing plate 40d to support the pressing table 40.

[0093] That is to say, in this embodiment, initially, the plurality of pressing table supporting members 50 jointly support the pressing table 40, making the pressing table 40 stably supported and safe to use without falling.

[0094] In addition, according to an embodiment of the present invention, the present application further includes an adjusting member 80 for adjusting the height position of the pressure sensor 20.

[0102] Therefore, the present application in the second embodiment provides a pressure maintaining device. On the premise of including the pressure sensor quick-release pressure maintaining jig head 1000, a workpiece is fixed on its workpiece fixing seat 2000, and an adhesive layer is provided on the upper end surface of the corresponding workpiece. Another workpiece is fixed at the bottom of the pressing table 40 of the pressure sensor quick-release pressure maintaining jig head 1000. During the downward movement of the pressure sensor quick-release pressure maintaining jig head 1000, the workpiece fixed thereon can be stably pressed and fixed to the upper end surface of the workpiece on the workpiece fixing seat 2000. During this process, as described in the first embodiment, the pressure sensor quick-release pressure maintaining jig head 1000 has a slow pressure function and a pressure maintaining function, so that the two corresponding workpieces to be pressed and fixed are not easily damaged, making the present application in the second embodiment also safe and reliable to use.

[0103] Moreover, as described in the first embodiment, the pressure sensor 20 on the pressure sensor quick-release pressure maintaining jig head 1000 can also be quickly disassembled and replaced when it breaks down, making the present application in the second embodiment also convenient and reliable to use.

[0105] Therefore, when the power plate 10 moves up and down, the up-and-down direction is oriented by the guiding columns 90, that is, the power plate 10 will not shift circumferentially. When it drives the pressing table 40 to move up and down, the pressing table 40 will not shift circumferentially either, making the pressure maintaining device of the present application have a better use effect.

[0106] Furthermore, the pressure sensor quick-release pressure maintaining jig head 1000 provided by the present application and the pressure maintaining device having it both have excellent use effects as a whole, making them suitable for popularization.
