Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a ball sliding pressure-maintaining fixture. Background Art

[0002] In the manufacturing process of various smart devices, such as smartphones, cameras, tablet computers and smart bracelets, it is often necessary to fix two workpieces that constitute their structure together by smooth pressing with glue. For example, small parts such as the camera and lighting that constitute a smartphone need to be fixed to its back panel by smooth pressing with hot melt glue.

[0003] Conventionally, when pressing and fixing two corresponding workpieces, a hot pressing device including a jig table and a workpiece pressing jig located directly above the corresponding jig table is generally set up, and the workpiece heating support plate of the corresponding jig table is used to fix the large workpiece, and the small workpiece is fixed by applying hot melt adhesive on the upper surface of the corresponding large workpiece, and an elastic hot pressing column that can float up and down is set in the corresponding workpiece pressing jig. When the corresponding workpiece pressing jig moves downward for a certain stroke to press down the corresponding large workpiece, the elastic hot pressing column can press the small workpiece downward for a certain period of time, and when the corresponding hot melt adhesive is melted, the corresponding large workpiece and the corresponding small workpiece are pressed and fixed together.

[0004] The bottom surface of the conventional workpiece pressing fixture has a guide groove upwardly provided to realize the clamping of the elastic hot pressing column, and the elastic hot pressing column can move up and down in the corresponding guide groove.

[0005] Although the workpiece pressing fixture of the above-mentioned structure is widely used, the inventor of this patent found in actual work that it still has certain defects and shortcomings in use.

[0006] Specifically, on the one hand, since the elastic hot pressing column is a multi-layer structure, when its outer wall frequently rubs up and down with the inner wall of the guide groove, it is easy to rub and damage its own multi-layer structure and the corresponding guide groove. When they are all worn, the elastic hot pressing column is prone to jamming when it moves up and down, resulting in a short service life of the entire workpiece pressing fixture. On the other hand, the elastic hot pressing column also includes a pressure sensor for measuring pressure. When the elastic hot pressing column is stuck when it moves up and down, the pressure measurement of the pressure sensor used is unstable, so that in actual use, the downward pressure of the elastic hot pressing column on the small workpiece cannot be accurately controlled, resulting in poor reliability and stability in the use of the entire workpiece pressing fixture.

[0007] In this regard, the inventor of this patent combined his work experience, conducted in-depth thinking on the problems encountered in the work, read a large amount of scientific research materials and literature, and through retrieval and novelty search, gradually conceived and designed this application to solve the relevant technical problems.

[0077] The ball sliding pressure-maintaining fixture 1000 according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0078] Reference Figures 1 to 7 As shown, the ball sliding pressure-maintaining fixture 1000 provided according to the embodiment of the utility model includes a power plate 10, a workpiece pressing head 20, a pressing head supporting member 30, a top pressure spring A40, a ball sliding member 50 and a heat pressurizing column 60 for pressing a part of the workpiece;

[0079] There are a plurality of press head support members 30, which are evenly fixed downward on the outer periphery of the power plate 10, and the lower ends thereof are respectively and horizontally provided with support blocks 301 facing inward; the workpiece press head 20 is limited to be directly below the power plate 10, and is supported by the plurality of support blocks 301, and the workpiece press head 20 is provided with a press hole 201 penetrating the upper and lower end surfaces thereof;

[0080] In addition, the bottom surface of the power plate 10 is upwardly provided with a guide groove 101 facing the pressure hole 201; the top pressure spring A40 is vertically clamped in the upper part of the guide groove 101, and its lower end is connected to the upper end of the heat pressurizing column 60; the lower end of the heat pressurizing column 60 is exposed in the pressure hole 201, and the upper end is limited in the guide groove 101, and can slide up and down along the guide groove 101 when being pressed upward;

[0081] There are multiple ball sliding members 50 , which are evenly arranged vertically on the inner wall of the guide groove 101 and abut against the outer wall of the heat pressurizing column 60 .

[0082] Based on the above, it can be clearly seen that when the present application is implemented specifically, it is mainly used as a ball sliding pressure-maintaining fixture 1000.

[0083] When applying the present application, the present application is assembled according to the structure described above, and a large workpiece (such as a mobile phone back panel, etc.) is fixed in advance using a workpiece heating supporting plate of a jig table, and then hot melt adhesive is applied to a preset position on the upper end surface of the fixed large workpiece, and the small workpiece to be pressed and fixed is applied on the corresponding upper surface of the hot melt adhesive. Subsequently, the present application is used again and controlled to move downward by a preset stroke to make the workpiece pressing head 20 press the fixed large workpiece. Synchronously, the heat pressurizing column 60 can press the fixed small workpiece and heat the corresponding small workpiece and the corresponding hot melt adhesive. When the corresponding hot melt adhesive is hot-melted and the corresponding small workpiece and the corresponding large workpiece are pressed and fixed for a preset time, the present application can be used to press and fix the corresponding large workpiece and the corresponding small workpiece that are bonded together.

[0084] The use of the above-mentioned application will obviously have the following technical effects:

[0085] First, since the present application is provided with a plurality of the ball sliding members 50, which are evenly arranged vertically on the inner wall of the guide groove 101 and abut against the outer wall of the heat pressurization column 60, when the heat pressurization column 60 is movably mounted in the guide groove 101, the heat pressurization column 60 can move up and down smoothly without getting stuck, and the heat pressurization column 60 itself is not easily damaged by friction, and the guide groove 101 is also not easily damaged by friction, so that the present application has a long service life.

[0086] Secondly, when the heat pressurized column 60 also includes a pressure sensor for measuring pressure, the heat pressurized column 60 is not prone to jamming when moving up and down. Therefore, the pressure measurement of the pressure sensor used is stable, so that in actual use, the downward pressure of the heat pressurized column 60 on the small workpiece to be pressed and fixed can be accurately controlled, so that the entire application has good reliability and stability.

[0087] Third, since the pressure spring A40 is provided at the upper end of the heat pressurizing column 60, the downward pressure is elastically buffered by the pressure spring A40, so that the heat pressurizing column 60 will not press the small workpiece to be pressed and fixed downward, so that the small workpiece to be pressed and fixed is not easily damaged, making the application more reliable.

[0088] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0089] Furthermore, in the specific implementation, Figure 2 and Figure 3 As shown, according to an embodiment of the present invention, a plurality of slots 102 are evenly opened vertically outward on the inner wall of the guide groove 101 , and a plurality of the ball sliding members 50 are correspondingly detachably mounted in the plurality of slots 102 .

[0090] Therefore, by providing a plurality of the card slots 102 , a plurality of the ball sliding members 50 can be correspondingly card-mounted, so that the plurality of the ball sliding members 50 are not easily displaced, so that the reliability and stability of the use are good.

[0091] Preferably, in this technical solution, Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, according to an embodiment of the present invention, each of the ball sliding members 50 includes a fixed clamping plate 501 and a plurality of balls 502;

[0092] Among them, the fixed card plate 501 is evenly provided with a plurality of clamping holes 5011 penetrating the inner and outer end surfaces thereof from top to bottom, and the plurality of balls 502 are correspondingly rotatably clamped in the plurality of clamping holes 5011, and the inner ends of the plurality of balls 502 are all extended into the guide groove 101 to abut against the outer wall of the heat pressurization column 60.

[0093] Therefore, when the plurality of balls 502 are correspondingly rotatably mounted in the plurality of mounting holes 5011, they are not easily displaced circumferentially, and when their inner ends are extended into the guide groove 101 to abut against the outer wall of the heat pressurization column 60, they can provide better rolling guiding properties, so that the heat pressurization column 60 can slide smoothly when sliding up and down in the guide groove 101.

[0094] And preferably, in this technical solution, continue to control Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, according to one embodiment of the utility model, the outer end surface of the fixed clamping plate 501 is provided with an outer enclosing part 5012 protruding outwardly from the outer periphery of the plurality of the clamping holes 5011, which is adapted to enclose the plurality of the balls 502; the inner end surface of the fixed clamping plate 501 is provided with an inner enclosing part 5013 protruding inwardly from the outer periphery of the plurality of the clamping holes 5011, which is adapted to enclose the plurality of the balls 502, and the inner enclosing part 5013 does not extend into the guide groove 101.

[0095] Therefore, by setting up a plurality of the outer enclosing parts 5012 and the inner enclosing parts 5013 to enclose and limit the plurality of the balls 502, it is difficult for the plurality of the balls 502 to slide out of the clamping holes 5011 at their positions, so that the plurality of the ball sliding parts 50 of the present application have good stability in use and a long service life.

[0096] Furthermore, in the specific implementation, Figure 2 and Figure 5 As shown, according to one embodiment of the utility model, the present application further includes a fixing block A70 and a pressure sensor A80;

[0097] The fixing block A70 is fixed between the upper end of the top pressure spring A40 and the bottom of the pressure sensor A80 ; the pressure sensor A80 is fixed at the top of the guide groove 101 .

[0098] Therefore, it can be clearly seen that the present application sets the pressure sensor A80 so that the downward pressure of the hot pressurizing column 60 on the small workpiece to be pressed and fixed can be measured in real time, so that the corresponding downward pressure can be controlled in real time.

[0099] Furthermore, in the specific implementation, continue to compare Figure 2 and Figure 5 As shown, according to an embodiment of the utility model, the present application also includes a plurality of guide columns 90; a plurality of guide holes 202 penetrating the upper and lower end surfaces are evenly opened on the periphery of the workpiece pressing head 20; the plurality of guide columns 90 are evenly fixed downward on the lower periphery of the power plate 10, and the lower ends thereof correspond to interference fit and can be movably penetrated into the plurality of guide holes 202.

[0100] Therefore, when the lower ends of the plurality of guide posts 90 are interference-fitted and movably inserted into the plurality of guide holes 202 provided on the workpiece pressing head 20, the workpiece pressing head 20 is not easily displaced in the circumferential direction, making it stable and reliable to use.

[0101] In addition, in the specific implementation, or reference Figure 2 and Figure 5 As shown, according to an embodiment of the utility model, the present application further includes a plurality of top pressure springs B100 ; the plurality of top pressure springs B100 are evenly fixed between the periphery of the lower bottom surface of the power plate 10 and the periphery of the upper end surface of the workpiece pressing head 20 .

[0102] Therefore, when the workpiece pressing head 20 moves downward through a preset stroke to press down the fixed large workpiece, the downward force is elastically buffered by the multiple pressing springs B100, so that the workpiece pressing head 20 will not press down hard on the large workpiece to be pressed and fixed, so that the large workpiece to be pressed and fixed is not easily damaged, making the use reliability of the present application better.

[0103] Furthermore, in this technical solution, still refer to Figure 2 and Figure 5As shown, according to one embodiment of the utility model, the present application further includes a plurality of fixing blocks B110 and a plurality of pressure sensors B120;

[0104] Among them, multiple fixed blocks B110 are correspondingly fixed between the upper ends of multiple top pressure springs B100 and the bottoms of multiple pressure sensors B120; the lower bottom surface of the power plate 10 is evenly opened with multiple accommodating grooves 103 corresponding to those located directly above the multiple top pressure springs B100, and multiple pressure sensors B120 are correspondingly fixed in the multiple accommodating grooves 103.

[0105] Therefore, it can be clearly seen that the present application sets up a plurality of the pressure sensors B120 so that the downward pressure of the workpiece pressing head 20 on the large workpiece to be pressed and fixed can be measured in real time, so that the corresponding downward pressure can also be controlled in real time.

[0106] Again, in the specific implementation, or reference Figure 2 and Figure 5 As shown, according to one embodiment of the present utility model, the heat pressurized column 60 includes a copper column 601, a heat insulating block 602 and an extension column 603;

[0107] Among them, the copper column 601, the insulation block 602 and the extension column 603 are connected in sequence from bottom to top; the lower end of the top pressure spring A40 is connected to the upper part of the extension column 603; the side wall of the copper column 601 is provided with a heating channel extending into the interior thereof, a heating rod 604 extending outward thereof is fixed in the heating channel, and the side wall of the copper column 601 is also connected to the outside with a temperature detection line 605.

[0108] From the above, we can understand that:

[0109] On the one hand, the present application provides heat insulation by setting the heat insulation block 602, so that after the copper column 601 is heated, it can transfer the heat downward to the small workpiece it is pressed as much as possible, so that the hot melt glue set at the bottom of the corresponding small workpiece is heated quickly so that it can be quickly melted.

[0110] On the other hand, the present application provides the insulation block 602 for isolation, so that the components such as the pressure spring A40 provided on the upper part of the insulation block 602 are not easily deformed by heat, so that the components such as the pressure spring A40 provided on the upper part of the insulation block 602 have a long service life and stable performance.

[0111] Furthermore, by connecting the heating rod 604 to a heating component, the copper column 601 can be heated. When it is heated independently, due to its small volume and size, it is also heated quickly as a whole, and can indeed quickly conduct heat downward to the small workpieces and hot melt adhesive to be pressed and fixed at the bottom, so that the corresponding hot melt adhesive can indeed be quickly heated and melted evenly, so that a better hot melting effect can be quickly achieved, so that the corresponding small workpieces to be pressed and fixed can be well hot pressed and fixed. By setting the temperature detection line 605 to be connected to a main control device, the heating temperature of the copper column 601 can be detected in real time, so that the operator can know in real time whether the heating temperature of the copper column 601 meets the specified requirements.

[0112] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be effectively improved.

[0113] It should be added that in the specific implementation, Figure 1 and Figure 3 As shown, according to one embodiment of the utility model, a connecting seat 104 is provided in the middle of the upper end surface of the power plate 10; the connecting seat 104 is suitable for connecting to a lifting device, and the lifting device is preferably a lifting cylinder, a cylinder-driven linear module or a screw-driven linear module.

[0114] It is further necessary to add that in the specific implementation, Figure 2 , Figure 4 and Figure 5 As shown, according to one embodiment of the utility model, the lower end of the pressure hole 201 is formed as a constriction, and the outer diameter of the lower end of the copper column 601 of the hot pressurized column 60 is smaller than the outer diameter of the upper end, so that a lower supporting surface 6011 adapted to be supported by the inner wall of the constriction is formed in its lower middle part; under this optimization scheme, initially, the top pressure spring A40 and the plurality of top pressure springs B100 are in a natural state or a slightly compressed state.

[0115] Therefore, before using the present application, the lower end of the copper column 601 of the hot pressurizing column 60 is supported by the inner wall of the shrinkage, so that the top pressure spring A40 will not be pulled down for a long time due to its gravity, etc., so that the service life of the top pressure spring A40 is long; and before using the present application, the workpiece pressure head 20 is supported by the support blocks 301 of the plurality of pressure head support members 30, so that the top pressure spring B100 will not be pulled down for a long time due to its gravity, etc., so that the service life of the top pressure spring B100 is also long;

[0116] It is further necessary to add that in the specific implementation, continue to compare Figure 2 and Figure 5As shown, according to one embodiment of the utility model, the guide groove 101 and the plurality of receiving grooves 103 all penetrate to the upper end surface of the power plate 10, and the upper end surface of the power plate 10 is provided with a plurality of detachable seats 105 for correspondingly covering the guide groove 101 and the plurality of receiving grooves 103.

[0117] Therefore, when removing the multiple detachable seats 105, it is convenient to repair or replace the components such as the top pressure spring A40, the pressure sensor A80, the multiple top pressure springs B100, the multiple pressure sensors B120 and the ball sliding member 50, so that the overall maintenance of the present application is also very convenient and effortless.

[0118] Other embodiments and the like are not described here by way of example.
