Description

Technical Field

[0001] The utility model relates to the technical field of temperature measuring equipment, in particular to an embedded precise temperature measuring tool. 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 constituting their structure together by smooth pressing with adhesive. For example, it is necessary to fix the glass back panel constituting a smartphone to the rear surface of its back shell by smooth pressing with hot melt adhesive.

[0003] Conventionally, when pressing and fixing two corresponding workpieces (workpiece A and workpiece B), a pressure-maintaining device is generally required. The pressure-maintaining device generally includes a fixture table for fixing workpiece B and a pressing fixture head for pressing workpiece A. During operation, after workpiece B is fixed, hot melt adhesive is applied to the upper surface of workpiece B to prepare for bonding the corresponding workpiece A. The corresponding pressing fixture head is heated and moved downward for a preset stroke to press the corresponding workpiece A for a certain period of time. When the corresponding hot melt adhesive is heated and melted, the corresponding workpiece A can be pressed and fixed to the upper surface of the corresponding workpiece B.

[0004] Before using the above-mentioned pressure-maintaining device, a temperature detection fixture is also used to measure and calibrate the pressing temperature of the corresponding pressing fixture head. The temperature detection gauge used traditionally mainly includes a supporting plate suitable for being placed on the corresponding fixture table and a temperature detection component fixed on the corresponding supporting plate. During operation, the corresponding pressing fixture head is moved downward by a certain stroke to press down the corresponding temperature detection component. When the temperature value of the lower end of the corresponding pressing fixture head detected by the corresponding temperature detection component is equal to the set value, the heating of the corresponding pressing fixture head is stopped. At this time, the heating parameters of the corresponding pressing fixture head for the corresponding hot melt adhesive are calibrated. When the above-mentioned corresponding pressure-maintaining equipment is used subsequently, the temperature detection gauge used can be removed, and the workpieces A and B to be pressed can be fixed. Then, the corresponding pressing fixture head can be used to heat the corresponding hot melt adhesive according to the corresponding calibrated heating parameters, and the workpiece A and workpiece B to be pressed can be moved downward by a certain stroke to press down the corresponding workpiece A for a certain period of time. In this way, the corresponding workpiece A can be pressed and fixed to the upper surface of the corresponding workpiece B according to the calibrated temperature value.

[0005] However, the inventor of this patent discovered during work that the above operation has certain defects and shortcomings.

[0006] Specifically, in actual applications, since the hot melt adhesive and the downward pressing fixture head with heating function are separated by the workpiece A, there will be a certain error between the actual heating temperature value of the corresponding hot melt adhesive and the calibrated heating temperature value, making its heating temperature value not accurate enough, so that it cannot be heated according to the ideal calibrated temperature value to achieve a better hot melting effect.

[0007] In this regard, the utility model author of this patent combined actual work experience, thought about 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.

[0059] The following describes in detail the built-in precision temperature measuring fixture 1000 according to an embodiment of the present utility model with reference to the accompanying drawings.

[0060] Reference Figures 1 to 5As shown, the embedded precise temperature measuring gauge 1000 provided according to the embodiment of the utility model is used to measure the temperature inside the workpieces to be pressed, and the workpieces include workpiece A and workpiece B stacked from top to bottom.

[0061] Based on this, the present application includes a lower support plate 10 and a plurality of temperature detection lines 20;

[0062] Among them, a clamping groove 101 for clamping the workpiece A and the workpiece B is opened downwardly in the middle of the upper end surface of the lower support plate 10, and a wire arrangement groove 102 and a wire passing groove 103 connected with the wire arrangement groove 102 and passing through the clamping groove 101 are opened downwardly at the periphery of the upper end surface of the lower support plate 10; the first ends of multiple temperature detection wires 20 are fixedly installed in the wire arrangement groove 102, and the second ends are correspondingly fixedly installed in multiple wire passing grooves 103 and all extend into the clamping groove 101 so that they can be clamped between the lower bottom surface of the workpiece A and the upper end surface of the workpiece B.

[0063] Based on the above, it can be clearly seen that when the present application is implemented, it is mainly used as an embedded precision temperature measuring instrument 1000.

[0064] Specifically, when applying the present application, the present application is assembled according to the above-mentioned structure, and the present application is placed on the fixture table of the pressure-maintaining equipment as described in the background technology. Then, the workpiece B (the upper surface does not contain hot-melt adhesive) that needs to be pressed and fixed or the mold whose size and structure are completely equivalent to the workpiece B is first fixed into the clamping groove 101 opened on the lower support plate 10 described in the present application, and then the second ends of the multiple temperature detection lines 20 are all extended into the clamping groove 101 so as to be attached to the upper surface of the workpiece B (the upper surface does not contain hot-melt adhesive) to be pressed and fixed or the upper surface of the mold whose size and structure are completely equivalent to the workpiece B. Then, the workpiece A that needs to be pressed and fixed or the mold whose size and structure are completely equivalent to the workpiece A is fixed into the clamping groove 101 opened on the lower support plate 10 described in the present application so as to be stacked on the workpiece B (the upper surface does not contain hot-melt adhesive).

[0065] Subsequently, the pressing fixture head of the pressure-maintaining equipment as described in the background technology can be used to press the workpiece A or the mold whose size and structure are completely equivalent to the workpiece A to a preset stroke and simultaneously heat the workpiece A or the mold whose size and structure are completely equivalent to the workpiece A. When the heating temperature values ​​measured by the multiple temperature detection lines 20 are basically equal to the preset values ​​set in advance that can make the hot melt adhesive achieve the best hot melting effect, the heating of the corresponding pressing fixture head is stopped. At this time, the heating parameters of the corresponding pressing fixture head are calibrated.

[0066] Finally, when the pressure-maintaining device described in the background technology is officially used, this application can be removed, and the workpiece A and workpiece B to be pressed can be fixed from top to bottom on the jig table (hot melt adhesive will be attached to the upper surface of workpiece B at this time), and then, the pressing jig head of the corresponding pressure-maintaining device is heated according to the corresponding calibrated heating parameters, and it is made to move downward for a certain distance to force it to press down the corresponding workpiece A for a certain period of time. In this way, the corresponding workpiece A can be pressed and fixed to the upper surface of the corresponding workpiece B according to the calibrated temperature value.

[0067] The use of the above-mentioned application will obviously have the following technical effects:

[0068] The heating temperature measured by the multiple temperature detection lines 20 set in the present application is the temperature of the lower bottom surface of the workpiece A and the upper surface of the workpiece B. The temperature value measured here is basically equal to the heating temperature value of the hot melt adhesive mounted on the upper surface of the workpiece B. When the temperature value measured here is equal to the preset value for the hot melt adhesive mounted on the upper surface of the workpiece B to achieve the best hot melting effect, it can be achieved to calibrate the heating parameters of the pressing fixture head of the corresponding pressure-holding device as accurately as possible, so that when using the present application, the temperature detection position is more accurate, the temperature measurement effect will be better and more reliable, so that when the pressure-holding device described in the background technology is actually used, the error between the actual heating temperature of the corresponding hot melt adhesive and the heating temperature corresponding to the calibrated heating parameters can be greatly reduced, so that its heating temperature can be as accurate as possible, so that it can be heated as much as possible according to the ideal heating temperature corresponding to the calibrated heating parameters to achieve a better hot melting effect.

[0069] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0070] Furthermore, in a specific implementation, according to an embodiment of the present invention, a second end of each temperature detection wire 20 is connected to a temperature measurement thermocouple (not shown).

[0071] In this regard, it can be understood that the connected thermocouple sheet for temperature measurement (not shown) will obviously be very thin, so that it occupies little space, is easy to use, and makes the temperature measurement reliable.

[0072] Furthermore, in the specific implementation, Figure 2 , Figure 4 and Figure 5 As shown, according to one embodiment of the utility model, the clamping slot 101 penetrates through the lower bottom surface of the lower support plate 10, and a plurality of supporting blocks 104 for supporting the workpiece A are evenly protruded inwardly from the lower periphery of the clamping slot 101, and the end of each of the supporting blocks 104 is cut downward to form a supporting step 1041 for supporting the workpiece B.

[0073] Based on this, in the present technical solution, according to an embodiment of the utility model, the second ends of the multiple temperature detection wires 20 and the corresponding multiple temperature measurement thermocouples connected thereto are at heights flush with the upper end surface of the supporting block 104; the height of the supporting step 1041 is equal to the thickness of the workpiece B.

[0074] Therefore, it can be clearly seen that when the present application is actually used, when the present application is placed on the jig table of the pressure-maintaining equipment described in the background technology, the jig table of the pressure-maintaining equipment described in the background technology will lift and support the lower bottom surface of the workpiece B that is not the lifting area of ​​the lifting step 1041. In this way, the workpiece B can be firmly lifted. At the same time, the workpiece A is stacked on the workpiece B, and is jointly lifted and supported by the workpiece B and the lifting block 104, so that the workpiece A is also firmly lifted.

[0075] Furthermore, in this technical solution, Figure 1 , Figure 2 and Figure 4 As shown, according to one embodiment of the present invention, at least one set of two lifting blocks 104 that lift the outer periphery of the workpiece A towards each other are detachably mounted with a movable clamping block 105 for pressing and fixing the outer periphery of the workpiece A downward.

[0076] Therefore, after the workpiece A and the workpiece B are stacked and fixed in the clamping groove 101, the outer periphery of the workpiece A can also be clamped by the movable clamping block 105, so that the workpiece A is fixed more stably and is not easy to shift up and down.

[0077] Preferably, in the present technical solution, a screw hole 107 is formed on the lower support plate 10, and a fixing hole 1051 penetrating the upper and lower end surfaces is formed at the end of the movable clamp block 105. The movable clamp block 105 is fixed as a whole with the lower support plate 10 by a fastening bolt A106 screwed into the fixing hole 1051 and the screw hole 107 from top to bottom. In this way, the outer periphery of the workpiece A is clamped and fixed by the end of the movable clamp block 105.

[0078] In addition, in the specific implementation, Figure 1 , Figure 3 and Figure 4 As shown, according to an embodiment of the utility model, the present application also includes a cover plate A30 for covering the cable groove 102 and the cable groove 103 , and the cover plate A30 is detachably fixed on the periphery of the upper end surface of the lower support plate 10 .

[0079] Therefore, by installing the cover plate A30 to seal and cover the temperature detection line 20 fixed in the cable groove 102 and the cable groove 103, the temperature detection line 20 is not exposed, making the application more beautiful and neat as a whole.

[0080] Furthermore, in a specific implementation, according to an embodiment of the utility model, a plurality of positioning holes A301 are evenly opened downwardly on the periphery of the upper end surface of the cover plate A30 and penetrate to its lower bottom surface, and a plurality of positioning holes B108 are evenly opened downwardly on the periphery of the upper end surface of the lower support plate 10 and penetrate to its lower bottom surface, and the plurality of positioning holes B108 are correspondingly located directly below the plurality of positioning holes A301, and the inner diameter of the plurality of positioning holes B108 is equal to the outer inner diameter of the plurality of positioning holes A301.

[0081] Therefore, when the present application is actually used, a pressing guide column will be arranged along the up and down directions on the jig table or the pressing jig head of the pressure-maintaining device. When the pressing guide column is interference-fitted through the positioning hole A301 and the positioning hole B108, the present application can be placed stably and not easily displaced circumferentially, thereby making the present application more reliable in use.

[0082] Preferably, in the present technical solution, according to an embodiment of the present utility model, a detection position mark 302 for marking the temperature detection position of the temperature detection line 20 at the corresponding position is provided on the upper end surface of the cover plate A30 corresponding to the second ends of the plurality of temperature detection lines 20 .

[0083] It should be noted here that when the present application is used to actually perform temperature detection, the temperature measurement position detected by each temperature detection line 20 will be different. When the temperature deviation measured at a certain temperature measurement position is large and abnormal, the detection position mark 302 at the corresponding position can be compared to check whether there is a problem with the temperature detection line 20 at that location, or check whether there is an abnormality at the corresponding position of the fixture table / down-pressing fixture head of the pressure-maintaining equipment used, etc., so as to trace the source and find the problem.

[0084] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be effectively improved.

[0085] It should be added that, in the specific implementation, continue to compare Figure 1 , Figure 3 and Figure 4 As shown, according to one embodiment of the present utility model, the present application further includes an operating handle 50;

[0086] Among them, the operating handle 50 is connected to the lower support plate 10 to form an integral body, and the upper end surface of the operating handle 50 is provided with a through groove 501 connected to the cable arrangement groove 102 along its length direction, and the first ends of multiple temperature detection lines 20 extend into the through groove 501 and are led out from the end of the through groove 501.

[0087] Therefore, in actual application, the operator can simply control the present application by holding the operating handle 50, making the present application convenient to use.

[0088] Moreover, in the specific implementation, it is still necessary to compare Figure 1 , Figure 3 and Figure 4 As shown, according to an embodiment of the utility model, the present application also includes a cover plate B60 for covering the through slot 501 , and the cover plate B60 is detachably fixed on the upper end surface of the operating handle 50 .

[0089] Therefore, by installing the cover plate B60 to seal and cover the temperature detection line 20 fixed in the through groove 501, the temperature detection line 20 is not exposed and the overall application is further made more beautiful and neat.

[0090] It should also be added that, in a specific implementation, according to an embodiment of the utility model, the cover plate A30 is detachably fixed to the periphery of the upper end surface of the lower support plate 10 by means of fastening bolts B40; the cover plate B60 is detachably fixed to the upper end surface of the operating handle 50 by means of fastening bolts C70, and the operating handle 50 and the cover plate B60 are both made of heat-insulating materials with poor thermal conductivity, so as to prevent burns when holding them.

[0091] Other embodiments and the like are not described here by way of example.

[0092] In summary, the embedded precision temperature measuring and checking fixture 1000 provided by the present application, in specific implementation, the heating temperature measured by the multiple temperature detection lines 20 of the present application is the temperature of the lower bottom surface of the workpiece A and the upper surface of the workpiece B. The temperature value measured here is basically equal to the heating temperature value of the hot melt adhesive mounted on the upper surface of the workpiece B. When the temperature value measured here is equal to the preset value for the hot melt adhesive mounted on the upper surface of the workpiece B to achieve the best hot melting effect, it can be achieved to calibrate the heating parameters of the pressing fixture head of the corresponding pressure-holding device as accurately as possible, so that when using the present application, the temperature detection position is more accurate, the temperature measurement effect will be better and more reliable, so that when the pressure-holding device described in the background technology is actually used, the error between the actual heating temperature of the corresponding hot melt adhesive and the heating temperature corresponding to the calibrated heating parameters can be greatly reduced, so that its heating temperature can be as accurate as possible, so that it can be heated as much as possible according to the ideal heating temperature corresponding to the calibrated heating parameters to achieve a better hot melting effect.

[0093] Furthermore, the embedded precise temperature measuring fixture 1000 provided by the present application is indeed extremely practical and has excellent use effect, which makes the present application inevitably have a good market promotion value, and the present application is also bound to be very popular and will be effectively popularized.
