Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but only represents the selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0041] Please refer to Figure 1 , which is the structural diagram of the high-temperature hot-melt device 100 provided by the present invention. The high-temperature hot-melt device 100 provided by the present invention can first press two semi-finished products, then perform pre-fixing by melting and welding, and finally perform connection by melting and welding, avoiding the situation of product offset during the melting and welding process, being able to improve the production yield, without the need for manual pressing or fixing of the product, reducing the working intensity of personnel, and ensuring personnel safety.

[0042] Please refer to Figure 2 and Figure 3, The high-temperature hot-melting device 100 is used to weld and connect the first workpiece to be welded 101 and the second workpiece to be welded 102. The first workpiece to be welded 101 and the second workpiece to be welded 102 can be any two semi-finished products that need to be welded and connected. Generally, a hot-melting film is provided on the first workpiece to be welded 101. The hot-melting film is located between the first workpiece to be welded 101 and the second workpiece to be welded 102. After being heated at a high temperature, the hot-melting film melts and can bond the first workpiece to be welded 101 and the second workpiece to be welded 102 together. After cooling, the two are welded and connected. In this application, taking the first welded part 101 as a foamed heat-insulating cotton and the second welded part 102 as a heater as an example, the foamed heat-insulating cotton has an inner circular groove, and a layer of hot-melting film is placed in the groove. After the heater is placed in the groove, high-temperature hot melting is carried out. After the hot-melting film is melted by high temperature and cooled, the foamed heat-insulating cotton and the heater can be welded together to achieve the welding connection between the two.

[0043] The high-temperature hot-melting device 100 includes a workbench 10, a fixed pressing mechanism 20, a driving mechanism 30, a spot hot-melting mechanism 40, and a forming hot-melting mechanism 50.

[0044] Please refer to Figures 4 to 6 , The fixed pressing mechanism 20 is arranged on the workbench 10 and the fixed pressing mechanism 20 is connected to the driving mechanism 30. The driving mechanism 30 is used to drive the fixed pressing mechanism 20 to move on the workbench 10. Specifically, the driving mechanism 30 can include a driving member and a guide rail. The driving member is connected to the fixed pressing mechanism 20. The guide rail is arranged on the workbench 10. The fixed pressing mechanism is arranged on the guide rail. The driving member can drive the fixed pressing mechanism 20 to slide on the guide rail so that the fixed pressing mechanism 20 is located directly below the spot hot-melting mechanism 40 or the forming hot-melting mechanism 50.

[0045] The spot hot-melting mechanism 40 and the forming hot-melting mechanism 50 are arranged above the workbench. The spot hot-melting mechanism 40 and the forming hot-melting mechanism 50 can be arranged side by side. Specifically, a frame 11 is arranged on the workbench 10. The spot hot-melting mechanism 40 and the forming hot-melting mechanism 50 are arranged on the frame 11 in sequence, for example, arranged in sequence from left to right. A cabinet 12 can also be arranged on the workbench 10. The fixed pressing mechanism 20, the driving mechanism 30, the spot hot-melting mechanism 40, and the forming hot-melting mechanism 50 are all arranged in the receiving space of the cabinet 12.

[0046] The dot hot melting mechanism 40 includes a plurality of dot heating heads 401 arranged at intervals. The dot heating heads 401 can press against a local position of the second workpiece to be welded 102 during welding and heat the pressed local position (such as heating in a dot matrix form). After cooling, the two workpieces to be welded can be locally fixed, that is, the second workpiece to be welded 102 and the first workpiece to be welded 101 can be pre-fixed by melting. Setting a plurality of dot heating heads 401 can fix multiple local positions of the two workpieces to be welded, improve the fixing strength of the pre-fixing by melting, and avoid the position offset of the product.

[0047] The forming hot melting mechanism 50 includes a forming heating head 501, and the forming heating head 501 has the same shape as the second workpiece to be hot melted 102. That is, the forming heating head 501 can press against all positions of the second workpiece to be welded 102 during welding and heat all positions of the second workpiece to be welded 102 (i.e., forming heating). After cooling, all positions of the second workpiece to be welded 102 can be fixed on the first workpiece to be welded 101, that is, the second workpiece to be welded 102 and the first workpiece to be welded 101 can be welded and connected to complete the high-temperature hot melting process.

[0048] The fixed pressing mechanism 20 includes a fixed component 21, a transmission component 22 located on the side of the fixed component 21, and a pressing strip 23 connecting the transmission component. The transmission component 22 is used to drive the pressing strip 23 to move on the fixed component 21. Specifically, the fixed component 21 is used to accommodate the first workpiece to be welded 101 and the second workpiece to be welded 102. The transmission component 22 can adjust the position of the pressing strip 23 on the fixed component 21, so that the pressing strip 23 presses the first workpiece to be welded 101 and the second workpiece to be welded 102, preventing position offset and facilitating welding. Moreover, when the dot hot melting mechanism 40 is heating, the pressing strip 23 is located in the gap between adjacent dot heating heads 401, that is, the pressing strip 23 can avoid the dot heating heads 401 while pressing the two workpieces to be welded, which is beneficial to the pre-fixing by melting. After the two workpieces to be welded are pre-fixed by melting, there is no need for the pressing strip to press anymore. The transmission component 22 can drive the pressing strip 23 to move to the side of the fixed component 21, that is, the pressing strip 23 no longer occupies the space above the fixed component 21, avoiding the pressing strip 23 from affecting the subsequent forming hot melting process.

[0049] When the high-temperature hot melting device 100 provided in this embodiment performs high-temperature melting of the first workpiece to be welded and the second workpiece to be welded, it includes:

[0050] Fixing the first workpiece to be welded 101 in the fixed component 21;

[0051] After the second workpiece to be welded 102 is placed on the first workpiece to be welded 101, the transmission assembly 22 is used to drive the pressing strip 23 to move above the second workpiece to be welded 102 and drive the pressing strip 23 to move downward to press the second workpiece to be welded 102 and the first workpiece to be welded 101 tightly together;

[0052] The driving mechanism 30 is used to drive the fixed pressing mechanism 20 to move below the point hot melting mechanism 40. The point hot melting mechanism 40 presses down for heating and cooling and pre-fixes the welding of the second workpiece to be welded 102 and the first workpiece to be welded 101. When the point hot melting mechanism 40 is heating, the point heating press head 401 abuts against a partial position of the second workpiece to be welded 102, and the pressing strip 23 is located in the gap between adjacent point heating press heads 401;

[0053] The point hot melting mechanism 40 moves upward to reset, and the transmission assembly 22 is used to drive the pressing strip 23 to move to the side of the fixing assembly 21;

[0054] The driving mechanism 30 is used to drive the fixed pressing mechanism 20 to move below the forming hot melting mechanism 50. The forming hot melting mechanism 50 presses down for heating and cooling and welds and connects the second workpiece to be welded 102 and the first workpiece to be welded 101; when the forming hot melting mechanism 50 is heating, the forming heating press head 501 abuts against the entire position of the second workpiece to be welded 102.

[0055] The high-temperature hot-melt device 100 provided by the present invention includes a workbench 10, a fixed pressing mechanism 20, a driving mechanism 30, a dot hot-melt mechanism 40, and a forming hot-melt mechanism 50. The driving mechanism 30 can drive the fixed pressing mechanism 20 to move on the workbench 10. The dot hot-melt mechanism 40 includes a plurality of dot heating heads 401 arranged at intervals. The forming hot-melt mechanism 50 includes a forming heating head 501, and the shape of the forming heating head 501 is the same as that of the second workpiece to be hot-melted 102. The fixed pressing mechanism 20 includes a fixing component 21, a transmission component 22, and a pressing strip 23. The transmission component 22 can drive the pressing strip 23 to move on the fixing component 21. When performing high-temperature welding, the fixing component 10 can fix the first workpiece to be welded 101, and the transmission component 22 can drive the pressing strip 23 to press the first workpiece to be welded 101 and the second workpiece to be welded 102 to prevent the product from shifting in position. When the dot hot-melt mechanism 40 heats up, the dot heating head 401 can abut against a partial position of the second workpiece to be welded 102 to realize pre-fixing the welding of the two welded workpieces. Moreover, the pressing strip 23 is located in the gap between adjacent dot heating heads 401. The pressing strip 23 can press the product without affecting the dot hot-melt mechanism 40 to perform pre-fixing of the weld. After the pre-fixing of the weld, the pressing strip 23 is moved away. When the forming hot-melt mechanism 50 heats up, the forming heating head 501 abuts against the entire position of the second workpiece to be welded 102, realizing the welded connection of the two welded workpieces, avoiding the situation of product shift during the welding process, ensuring the position accuracy of the product, being able to improve the production yield, eliminating the need for manual pressing or fixing of the product, reducing the labor intensity of the personnel, and ensuring the safety of the personnel.

[0056] Please refer to again Figure 4 , the fixing component 21 includes a bakelite fixture 211 and a cover plate 212, and the fixing component 21 can firmly fix the first workpiece to be welded 101. Specifically, the bakelite fixture 211 is provided with a receiving groove 218 having the same shape as the first workpiece to be hot-melted 101. The receiving groove 218 is used for receiving the first workpiece to be hot-melted 101. The cover plate 212 is movably connected to one side of the bakelite fixture 211. The cover plate 212 can rotate towards the bakelite fixture 211 and cover the bakelite fixture 211. The cover plate 212 is provided with a window 219 having the same shape as the first workpiece to be hot-melted 101. When the cover plate 212 covers the bakelite fixture 211, the window 219 is opposite to the receiving groove 218 in position.

[0057] The fixing assembly 21 further includes two elastic members 213, which are respectively located on two adjacent sides of the connection position between the cover plate 211 and the bakelite jig 212, and the two ends of the elastic member 213 are respectively connected to the bakelite jig 211 and the cover plate 212. The cover plate 212 can also be opened in a direction away from the bakelite jig 211. When the cover plate 212 is opened, the two elastic members 213 are stretched, and when the cover plate 212 is closed, the restoring force of the elastic members 213 can make the cover plate 212 close tightly.

[0058] A tower buckle 214 is provided on one side of the bakelite jig 211, and the tower buckle 214 is located on the side opposite to the connection position of the cover plate 212 and the bakelite jig 211, and the tower buckle 214 is used to lock the cover plate 212 and the bakelite jig 211 when the cover plate 212 is covered on the bakelite jig 211. A magnet 215 is fixed on the surface of the bakelite jig 211 close to the cover plate 212, and the magnet 215 is used to attract the cover plate 212 when the cover plate 212 is covered on the bakelite jig 211.

[0059] The transmission assembly 22 includes an X-axis cylinder 221, a Y-axis cylinder 222 and a downward pressure cylinder 223. The X-axis cylinder 221 and the Y-axis cylinder 222 are used to adjust the horizontal position and the vertical position of the pressure strip 23 on the plane of the fixed assembly 21. The downward pressure cylinder 223 is used to drive the pressure strip 23 to move downward. The pressure strip 23 is used to press the second part to be welded 102 and the first part to be welded 101. It can be understood that the downward pressure cylinder 223 can also be used to drive the pressure strip 23 to move upward after the pre-fixation is completed, so that the pressure strip 23 leaves the second part to be welded, and the X-axis cylinder 221 and the Y-axis cylinder 222 then drive the pressure strip 23 to move to the side of the fixed assembly, that is, to exit above the product to avoid affecting the downward pressure of the subsequent molding heating head.

[0060] A pressing block 231 is protruding from the surface of the pressure strip 23 close to the fixing assembly 21. When the pressing cylinder 223 drives the pressure strip 23 to move downward, the pressing block 231 abuts against the second hot-melt part 102. By arranging the pressing block 231 on the pressure strip 23, the second hot-melt part 102 can be more firmly abutted to prevent the second hot-melt part 102 from shifting.

[0061] See also Figure 7 and Figure 8 The point hot melt mechanism 40 includes a point heating component 41 and a point cooling component 42.

[0062] The described point heating assembly 41 includes a first servo motor 411, a first ball screw 412, a first connecting plate 413, a first heat insulation plate 414, a first heating plate 415, and a first heating tube 416. The first servo motor 411 is connected to the first ball screw 412. One end of the first ball screw 412 away from the first servo motor 411 is connected to the first connecting plate 413. The first connecting plate 413, the first heat insulation plate 414, and the first heating plate 415 are stacked in sequence. The first heat insulation plate 414 has a heat insulation function. The first heating tube 416 is inserted into the first heating plate 415. The surface of the first heating plate 415 away from the first heat insulation plate 414 is convexly provided with a plurality of spaced-apart point heating heads 401. The first heating tube 416 can generate heat to raise the temperature of the point heating heads 401 for high-temperature hot melting. The distance between adjacent point heating heads 401 exceeds the width of the pressing strip 23, that is, the point heating heads 401 can avoid the pressing strip 23 when heating. The first servo motor 411 is used to drive the first ball screw 412 to press a plurality of point heating heads 401 on the second workpiece to be welded 102 and perform dot matrix heating, that is, local heating.

[0063] Specifically, the point heating assembly 41 further includes a first support plate 417 and a first guide shaft 418. The first support plate 417 is arranged on the frame 11.

The forming and cooling press head 527 is used to cool the position where the forming and heating press head 501 heats the second workpiece to be welded 102 (that is, all positions of the second workpiece to be welded), so as to fix all positions of the second workpiece to be welded on the first workpiece to be welded, and further realize the fusion connection between the second workpiece to be welded 102 and the first workpiece to be welded 101.

[0073] Furthermore, for the high-temperature hot melting device 100 provided in this embodiment, when performing the high-temperature fusion welding of the first workpiece to be welded and the second workpiece to be welded, the steps are as follows:

[0074] Fix the first workpiece to be welded within the fixing assembly. Specifically, it includes: rotating the cover plate away from the bakelite jig and placing the first workpiece to be welded in the receiving groove of the bakelite jig; rotating the cover plate towards the bakelite jig to cover the bakelite jig, and the magnet attracts the cover plate; locking the tower buckle.

[0075] After the second workpiece to be welded is placed on the first workpiece to be welded, the transmission assembly drives the pressing strip to move above the second workpiece to be welded and drives the pressing strip to move downward to press the second workpiece to be welded and the first workpiece tightly together. Specifically, it includes: starting the X-direction cylinder and the Y-direction cylinder to drive the pressing strip to move to adjust the horizontal position and vertical position of the pressing strip on the plane of the fixing assembly; when the pressing block on the pressing strip aligns with the second workpiece to be welded, start the downward pressing cylinder, and the downward pressing cylinder drives the pressing strip to move downward, and the pressing strip presses the second workpiece to be welded and the first workpiece tightly together.

[0076] The driving mechanism drives the fixed pressing mechanism to move below the point hot melting mechanism, and the point hot melting mechanism presses down for heating and cooling and pre-fixes the welding of the second workpiece to be welded and the first workpiece to be welded. During heating, the pressing strip is located in the gap between adjacent point heating heads. Specifically, it includes: the driving mechanism drives the fixed pressing mechanism to move below the point heating assembly; the first servo motor drives the first ball screw to press several point heating heads on the second workpiece to be welded and perform dot matrix heating, and the point heating heads can avoid the pressing strip during heating; the first servo motor drives the first ball screw to lift the point heating heads, and the driving mechanism drives the fixed pressing mechanism to move below the point cooling assembly; the second servo motor drives the second ball screw to press several point cooling heads on the second workpiece to be welded and perform dot matrix cooling.

[0077] The point hot melting mechanism moves upward to reset, and the transmission assembly drives the pressing strip to move to the side of the fixing assembly. Specifically, it includes: the second servo motor drives the second ball screw to lift several point cooling heads; the downward pressing cylinder drives the pressing strip to move upward so that the pressing strip leaves the second workpiece to be welded; the X-direction cylinder and the Y-direction cylinder drive the pressing strip to move to the side of the fixing assembly.

[0078] The driving mechanism drives the fixed pressing mechanism to move below the forming hot melting mechanism, and the forming hot melting mechanism presses down for heating and cooling and welds and connects the second workpiece to be welded and the first workpiece to be welded. Specifically, it includes: the driving mechanism drives the fixed pressing mechanism to move below the forming heating assembly; the third servo motor drives the third ball screw to press the forming heating head on the second workpiece to be welded and perform forming heating; the first servo motor drives the first ball screw to lift the forming heating head, and the driving mechanism drives the fixed pressing mechanism to move below the forming cooling assembly; the fourth servo motor drives the fourth ball screw to press the forming cooling head on the second workpiece to be welded and cool it.

[0079] After the welding connection, it further includes: the forming and cooling assembly moves upward to reset, and the driving mechanism drives the fixed pressing mechanism to move to the loading position to take out the first workpiece to be welded and the second workpiece to be welded after the welding connection.

[0080] In the high-temperature hot-melting device 100 provided by the present invention, during actual application, an operator places the semi-finished product in the lower fixture (i.e., the fixed pressing mechanism). After the X-direction cylinder and the Y-direction cylinder adjust the position of the pressing strip, press the pressing button, and the downward pressing cylinder presses down. The pressing strip automatically presses the product tightly. After starting, the driving mechanism automatically sends the product under the spot heating head. The spot heating head is pre-heated to about 400 degrees. After pressing and heating for a certain time (the time set by the customer), it is lifted. Then it moves under the spot cooling head, presses the product and blows air to cool for a certain time and then is lifted. The downward pressing cylinder of the lower fixture rises, and the pressing strip leaves the second workpiece to be welded. The X-direction cylinder and the Y-direction cylinder drive the pressing strip to withdraw above the product to avoid affecting the downward pressing of the subsequent forming head. The driving mechanism automatically sends the product under the forming heating head. The forming heating head is pre-heated to about 400 degrees. After pressing and heating for a certain time (the time set by the customer), it is lifted. Then it moves under the forming cooling head, presses the product and blows air to cool for a certain time and then is lifted. The product is sent to the loading position, and the operator takes out the product to complete the product welding.

[0081] According to the product characteristics of the present invention: the heater needs to be fixed firmly before high-temperature hot melting, and the position of the heater cannot move during the cooling process until it reaches room temperature to be firmly bonded. The device is designed to first use multi-point hot melting to fix the heater firmly and then adopt the full forming hot-melting method. By designing the product fixed pressing mechanism of the present invention, two semi-finished products are first pressed tightly and then multi-point hot melting is performed on the product. After the welding is firm, the fixed pressing automatically withdraws, and the forming head then performs hot melting on the product. It realizes fixing two semi-finished products and welding them together by high temperature, and the position of the product will not shift. There is no need for manual pressing or fixing. The present invention replaces manual operation, avoids the uncertainty of manual operation, improves the yield and efficiency of the product, and at the same time avoids the problem of high-temperature scalding.

[0082] The high-temperature hot-melt device 100 provided by the present invention, when welding the heater to the foamed heat-insulating cotton, in the first step, place the foamed heat-insulating cotton in the fixture and arrange it neatly. In the second step, place the welding film on top of the heat-insulating cotton. In the third step, buckle the cover plate, and the magnet adsorbs the cover plate to press the heat-insulating cotton tightly, and then lock the tower buckle. In the fourth step, place the heater on the inner circle of the heat-insulating cotton, and the arrangement is completed. Start the X-direction and Y-direction cylinders to move upward above the product, and start the downward pressure cylinder. At this time, the fixed pressure head presses the heater and the welding film tightly on the heat-insulating cotton. Manually observe whether the heater is in the middle of the heat-insulating cotton. If it is not in the middle, start the cylinder to press it tightly again. Before production, the pressure head needs to be heated to about 400 degrees. When designing the position of the spot heating head, avoid the pressing strip position of the lower fixture and perform offset heating. When the product moves below the spot heating head, the servo motor drives the lead screw to press the spot heating head onto the heater, and heats for a certain period of time until the welding film melts, and then lift the spot heating head. When designing the position of the spot heating head, avoid the fixed pressure head position of the lower fixture and be consistent with the position of the spot heating head. When the product moves below the pressure head, the servo motor drives the lead screw to press the pressure head on the product, and at the same time blow air for a certain period of time to achieve the shaping and cooling effect. Before production, the pressure head needs to be heated to about 400 degrees. When the product moves below the pressure head, the servo motor drives the lead screw to press the pressure head on the product, and heats for a certain period of time until the welding film melts, and then lift the spot heating head. When the product moves below the pressure head, the servo motor drives the lead screw to press the pressure head on the product, and at the same time blow air for a certain period of time to achieve the shaping and cooling effect, and the production process of the product can be completed.

[0084] S10: Fix the first workpiece to be welded in the fixing component;

[0085] S20: After the second workpiece to be welded is placed on the first workpiece to be welded, the transmission component drives the pressing strip to move above the second workpiece to be welded and drives the pressing strip to move downward to press the second workpiece to be welded and the first workpiece to be welded tightly;

[0086] S30: The driving mechanism drives the fixed pressing mechanism to move below the spot hot-melt mechanism, and the spot hot-melt mechanism presses down for heating and cooling and pre-fixes the welding of the second workpiece to be welded and the first workpiece to be welded. When heating, the pressing strip is located in the gap between adjacent spot heating heads;

[0087] S40: The spot hot-melt mechanism moves upward to reset, and the transmission component drives the pressing strip to move to the side of the fixing component;

[0088] S50: The driving mechanism drives the fixed pressing mechanism to move below the forming hot-melt mechanism, and the forming hot-melt mechanism presses down for heating and cooling and welds and connects the second workpiece to be welded and the first workpiece to be welded.

[0089] It should be noted that all embodiments of the high-temperature hot-melt device provided by the present invention are applicable to the high-temperature hot-melt method provided by the present invention and can achieve the same or similar technical effects, which will not be elaborated here one by one.

[0090] In summary, for the high-temperature hot-melt device 100 and method provided by the present invention, the driving mechanism 30 can drive the fixed pressing mechanism 20 to move on the workbench 10. The spot hot-melt mechanism 40 includes a plurality of spaced-apart spot heating heads 401. The forming hot-melt mechanism 50 includes a forming heating head 501, and the shape of the forming heating head 501 is the same as that of the second workpiece to be hot-melted 102. The fixed pressing mechanism 20 includes a fixing component 21, a transmission component 22 and a pressing strip 23. The transmission component 22 can drive the pressing strip 23 to move on the fixing component 21. When performing high-temperature welding, the fixing component 10 can fix the first workpiece to be welded 101, and the transmission component 22 can drive the pressing strip 23 to press the first workpiece to be welded 101 and the second workpiece to be welded 102 to prevent the product from shifting in position. When the spot hot-melt mechanism 40 heats up, the spot heating head 401 can abut against a local position of the second workpiece to be welded 102 to realize pre-fixing the welding of the two workpieces. Moreover, the pressing strip 23 is located in the gap between adjacent spot heating heads 401. The pressing strip 23 can press the product without affecting the spot hot-melt mechanism 40 to perform pre-fixing of the welding. After the pre-fixing of the welding, the pressing strip 23 is moved away. When the forming hot-melt mechanism 50 heats up, the forming hot pressing head 501 abuts against the entire position of the second workpiece to be welded, realizing the welded connection of the two workpieces to be welded, avoiding the product shifting during the welding process, ensuring the position accuracy of the product, being able to improve the production yield, eliminating the need for manual pressing or fixing of the product, reducing the working intensity of the personnel, and ensuring the safety of the personnel.
