Description
Technical Field
[0001] This utility model relates to the field of hot melt technology, and in particular to a force-controlled hot melt equipment suitable for the production of 3C products. Background Technology
[0002] In the production process of 3C products, hot melt equipment is usually required to melt the hot melt column to form the desired mushroom head. In existing hot melt equipment, the displacement of the hot melt head is determined by the set stroke of the motor. The stroke of the hot melt head is fixed each time it presses down, and it travels to a fixed point to melt the hot melt column to form the mushroom head.
[0003] Existing equipment has the following technical defects: differences in product assembly and assembly tolerances can cause significant variations between hot-melt products. Therefore, the hot-melt pressure should vary irregularly with these assembly differences. However, the fixed stroke and displacement of the hot-melt head keep the pressure constant, which cannot adapt to the different pressure requirements caused by product differences. This results in poor consistency of the hot-melt effect and large fluctuations in product quality.
[0004] Therefore, it is necessary to provide a hot-melt device that can accommodate product differences while ensuring consistent hot-melt effects, in order to solve the above problems. Utility Model Content

In this embodiment, the top of the heating block 131 is fixed to the third adjustment block 123 of the adjustment assembly 120, and the hot-melt head 133 is provided at the bottom of the heating block 131.

The heating tube 134 is preferably a tubular heater, and two heating tubes 134 are provided. The temperature sensor 135 is preferably a K-type thermocouple with a temperature detection range of 200℃ to 1000℃ and a detection accuracy of 0.75%. It is understood that the model and quantity of the heating block 131 and the temperature sensor 135 are not limited to those in this embodiment.
[0048] The following is combined Figures 3-5As shown, in one embodiment of this utility model, the lifting assembly 110 further includes a lifting plate 112 and a guide shaft 113. The guide shaft 113 is fixedly installed, the lifting plate 112 is slidably connected to the guide shaft 113, and the upper and lower ends of the lifting plate 112 are respectively fixedly connected to the telescopic end of the driver 111 and the thermoforming assembly 130.

Figure 4 As shown. In this way, when the driver 111 extends and retracts to drive the lifting plate 112 to rise and fall along the four guide shafts 113, the connecting plate 124 of the adjusting component 120 drives the hot melt component 130 to rise and fall. The four guide shafts 113 make the lifting plate 112 rise and fall more smoothly, thereby realizing the smooth rising and falling and precise docking of the hot melt component 130.
[0049] In one embodiment, the driver 111 is preferably a servo motor and an electric cylinder that work together. The telescopic end of the electric cylinder is fixed to the upper end of the lifting plate 112. The servo motor and the electric cylinder work together to provide a short feedback response time and a small delay displacement, thereby enabling precise pressure control.
[0050] Combination Figures 2-5 As shown, in one embodiment of this utility model, the hot-melt equipment 100 further includes a frame 180, which has a horizontally arranged top plate 181. The structure of the other parts of the frame 180 is a conventional structure.

Four guide shafts 113 are respectively fixedly mounted on the bottom of the top plate 181.
[0051] Combination Figure 1 As shown, the frame 180 is also provided with a housing to enclose the various components of the hot melt equipment 100. The housing is a conventional configuration in the art and will not be described in detail.
[0052] The following is combined Figure 2-3 , Figure 9As shown, in one embodiment of this utility model, the hot-melt equipment 100 further includes a linear drive assembly 160, which is installed below the lifting assembly 110 and the hot-melt assembly 130 and extends along the X-axis or Y-axis direction. In one specific embodiment, the linear drive assembly 160 extends along the Y-axis direction. The base of the pressure sensing assembly 150 is installed on the linear drive assembly 160, and the linear drive assembly 160 drives the pressure sensing assembly 150 and its fixture assembly 140 to reciprocate between the loading / unloading position, the barcode scanning position, and the hot-melt position, thereby reciprocatingly transferring the product on the fixture assembly 140 between the loading / unloading position, the barcode scanning position, and the hot-melt position.
[0053] See Figure 9 As shown, in this embodiment, the linear drive assembly 160 is preferably a ball screw module. The seat of the pressure sensing assembly 150 is mounted on the slider of the ball screw module, and is driven by the ball screw module to slide and reciprocate in a linear direction, thereby driving the pressure sensing assembly 150 and the fixture assembly 140 to reciprocate. The structures of other parts of the ball screw module are conventional results in the art and will not be described in detail.
[0054] Understandably, the linear drive assembly 160 is not limited to a ball screw module. Other drive mechanisms can also be used, such as a motor, a lead screw, and a lead screw nut, which can also drive the pressure sensing assembly 150 to move back and forth in a straight line.
[0055] The following is combined Figure 1-3 , Figure 14 As shown, in one embodiment of the present invention, the hot melt equipment 100 further includes a barcode scanning component 170, which is installed on the side of the linear drive component 160 and located between the loading / unloading position and the hot melt position, for scanning the product fed into the hot melt position.
[0056] In this embodiment, the barcode scanning assembly 170 includes a barcode scanner 171, a support pole 172, and a mounting block 173.

The barcode scanner 171 is adjustablely mounted on the pole 172 via the mounting block 173, as... Figure 14As shown, the height of the barcode scanner 171 can be adjusted via the mounting block 173. The barcode scanner 171 is also electrically connected to the controller. In this embodiment, the scanning window of the barcode scanner 171 faces the linear drive assembly 160, meaning the scanning direction of the barcode scanner 171 is perpendicular to the moving direction of the linear drive assembly 160. The position facing the barcode scanner 171 is the scanning position. When the linear drive assembly 160 drives the pressure sensing assembly 150 and the fixture assembly 140 to the scanning position, the barcode scanner 171 scans the product on the fixture assembly 140.
[0057] The following is combined Figures 9-11 As shown, in one embodiment of this utility model, the base of the pressure sensing assembly 150 includes a base plate 152 and a top plate 153 disposed opposite to each other. The pressure sensor 151 is fixed between the base plate 152 and the top plate 153.

The other end of the pressure sensor 151 is fixed to the base plate 152 and there is a certain gap between this end and the top plate 153. For example, the left end of the pressure sensor 151 is fixed to the top plate 153, and the right end of the pressure sensor 151 is fixed to the base plate 152. In this case, there is a certain gap between the left end of the pressure sensor 151 and the base plate 152, and a certain gap between its right end and the top plate 153, so that the deformation of the pressure sensor 151 under pressure is not disturbed, thereby enabling the pressure sensor 151 to accurately sense the pressure on the product on the fixture assembly 140. The base plate 152 is fixed to the slider of the linear drive assembly 160, such as... Figure 9 As shown. The fixture assembly 140 is mounted on the top plate 153. The pressure sensor 151 is mounted on the bottom of the fixture assembly 140, which can provide more direct feedback on the force applied to the product during hot pressing, thereby facilitating precise control of the downward stroke of the driver 111 to achieve precise control of the downward pressure.
[0058] Preferably, the pressure sensor 151 has an accuracy of 0.03% and an operating temperature of 20-80℃, thereby enabling accurate detection of the thermal stress on the product during hot melting.
[0059] Continue reading Figures 10-11As shown, in this embodiment, the pressure sensing assembly 150 further includes a fixture carrier plate 154 and a limiting member 155. The fixture carrier plate 154 is movably mounted on the top plate 153 and serves to support the fixture assembly 140. The limiting member 155 is mounted on the side of the fixture carrier plate 154 to limit its position. More specifically, a connecting post and a strip-shaped sliding hole are provided between the fixture carrier plate 154 and the top plate 153. The connecting post passes through the sliding hole, thereby enabling relative sliding between the fixture carrier plate 154 and the top plate 153, thus adjusting the position of the fixture carrier plate 154 and the fixture assembly 140. The limiting member 155 is mounted at both ends of the base along the sliding direction of the fixture carrier plate 154, limiting the movement of the fixture carrier plate 154, that is, limiting the position of the fixture assembly 140.
[0060] In one specific embodiment, the fixture carrier plate 154 is provided with a sliding hole 1541 extending along the X-axis direction, and a connecting post is fixed on the top plate 153. The sliding hole 1541 on the fixture carrier plate 154 passes through the connecting post. Simultaneously, limiting members 155 are respectively provided at both ends of the top plate 153 in the X-axis direction. Each limiting member 155 includes a limiting block 1551 and a limiting post 1552 mounted on the limiting block 1551. The limiting block 1551 is fixed to the end of the top plate 153, and the limiting post 1552 protrudes towards the center of the top plate 153. Furthermore, the limiting posts 1552 of the two limiting members 155 protrude towards each other, as shown below. Figure 10 As shown, the limiting post 1552 abuts against both ends of the fixture carrier plate 154 to limit its movement.
[0061] Combination Figures 10-13 As shown, in this embodiment, the fixture carrier plate 154 and the fixture assembly 140 are provided with matching positioning posts and positioning holes. The positioning posts and positioning holes cooperate to achieve quick alignment and installation of the fixture assembly 140. In a specific embodiment, a positioning post 1542 is also fixed on the fixture carrier plate 154, and the bottom of the fixture assembly 140 is provided with a positioning hole 1411 corresponding to the positioning post 1542. When installing the fixture assembly 140, it passes through the positioning hole 1411 at its bottom onto the positioning post 1542 to achieve quick alignment and installation.
[0062] The following is combined Figure 9 , Figure 12-13As shown, in one embodiment of this utility model, the fixture assembly 140 includes a fixture base plate 141, a contouring fixture 142, a cover plate 143, and a fastening member 144. The fixture base plate 141 has a positioning hole 1411 at its bottom, and is detachably connected to the fixture carrier plate 154 of the pressure sensing assembly 150. The contouring fixture 142 is fixedly mounted on the fixture base plate 141, and has a product receiving cavity 1421. The shape of the product receiving cavity 1421 is designed according to the specific product requiring heat melting, and is not limited here. The cover plate 143 is pivotally connected to one end of the contouring fixture 142, and the cover plate 143 can pivotally open or close relative to the contouring fixture 142. Figure 13 As shown, when the cover 143 is opened, the product can be placed into or removed from the product receiving cavity 1421; as Figure 12 As shown, when the cover plate 143 is closed, it secures the product within the product receiving cavity 1421. The fastening member 144 is detachably connected between the conforming fixture 142 and the cover plate 143. Specifically, the lower end of the fastening member 144 is pivotally connected to the conforming fixture 142, and the upper end of the fastening member 144 is detachably fastened to the cover plate 143. The fastening member 144 is used to lock the closed cover plate 143 or release it so that the cover plate 143 can be opened. Specifically, when the fastening member 144 is pivoted under force, causing its upper end to disengage from the cover plate 143, the cover plate 143 can pivotally open; when the cover plate 143 is closed, the fastening member 144 pivots again so that its upper end re-fastens to the cover plate 143 to achieve locking.
[0063] Combined again Figures 10-13 As shown, in a preferred embodiment, the fixture assembly 140 further includes a cover plate detection sensor 145, which is mounted on the fixture base plate 141 or the seat of the pressure sensing assembly 150 or the fixture carrier plate 154, and is used to detect whether the cover plate 143 is closed on the contour fixture 142. Figures 10-11 As shown, in one specific embodiment, the cover plate detection sensor 145 is fixed to the fixture carrier plate 154 by a fixing plate, specifically fixed to the end of the fastening member 144 of the fixture assembly 140. Cover plate detection sensors 145 are respectively set on both sides of the fastening member 144. In this way, whether the fastening member 144 is fastened can be determined by whether there is a transmission signal between the two cover plate detection sensors 145, that is, whether the cover plate 143 is closed on the contour fixture 142, making the detection more convenient and accurate.
[0064] More preferably, the cover plate detection sensor 145 is a through-beam sensor, with two through-beam sensors respectively disposed on both sides of the fastening member 144. Figure 9As shown, when the fastening element 144 fastens the cover plate 143, the signal transmission between the two through-beam sensors is blocked by the fastening element 144. This signal can be used to determine that the cover plate 143 is closed, making the judgment more convenient. Of course, the cover plate detection sensor 145 can also be other detection devices.
[0065] See in combination Figure 1 , Figure 14 As shown, in one embodiment of this utility model, the hot melt equipment 100 further includes a display module 190, which is mounted on the housing and electrically connected to the controller for real-time display of the force control curve, thereby facilitating data viewing and analysis. Additionally, the housing is also equipped with a dual-start button electrically connected to the controller.
[0066] Let's combine them again below. Figures 1-14 The working principle and process of the hot-melt equipment 100 of this utility model are explained as shown.
[0067] Before starting the hot melt equipment 100, the horizontal position of the hot melt assembly 130 can be adjusted as needed. Combined with... Figure 6-7 As shown, by rotating the second adjusting block 122 around the Y-axis and leveling it, the first adjusting block 121 and the second adjusting block 122 are fixed by the fixing member 125. Then, the third adjusting block 123 is rotated around the X-axis and leveled, and the second adjusting block 122 and the third adjusting block 123 are fixed by the fixing member 125. This achieves the horizontal adjustment of the hot melt assembly 130, which is convenient and quick. Since the horizontal position of the hot melt assembly 130 can be adjusted before each hot melt, the position of the hot melt head 133 is ensured to be horizontal during hot melt, thereby ensuring the consistency of the hot melt mushroom head and improving product quality.
[0068] After the hot melt equipment 100 is started, the linear drive assembly 160 is controlled by the controller to operate, thereby driving the pressure sensing assembly 150 and the fixture assembly 140 to move to the loading and unloading position. Then, the product 200 is manually placed into the conformal fixture 142 of the fixture assembly 140, the cover plate 143 is closed, and then the fastening piece 144 is fastened onto the cover plate 143 to fix the cover plate 143 in place. Figure 12 As shown.
[0069] Then, the operator presses the dual start button with both hands, and the controller again controls the linear drive assembly 160 to run, driving the pressure sensing assembly 150 and the fixture assembly 140 to move to the scanning position, where the barcode scanner 171 scans the product 200. After scanning, the controller again controls the linear drive assembly 160 to run, driving the pressure sensing assembly 150 and the fixture assembly 140 to move to the hot melt position. At this time, the controller controls the driver 111 to run, causing the electric cylinder to move the adjusting assembly 120 and the hot melt assembly 130 downwards until the hot melt head 133 presses down on the cover plate 143 to hot melt the internal product. During this process, the controller can obtain the pressure of the pressure sensor 151 in real time and control the driver 111 to adjust the downward stroke according to the pressure, thereby accurately controlling the hot melt pressure, so that the downward pressure of the hot melt head 133 can adapt to products with assembly differences, ultimately making the hot melt effect of products with assembly differences consistent. After the hot melt is completed, the controller controls the driver 111 to run, causing the electric cylinder to move the adjusting assembly 120 and the hot melt assembly 130 upwards.
[0070] Then, the controller again controls the linear drive assembly 160 to drive its slider to move in the opposite direction, which in turn drives the pressure sensing assembly 150 and the fixture assembly 140 to move in the opposite direction to the loading and unloading position, where the product is manually removed. Then the product to be heat-melted is put in again, and the above process is repeated to continuously heat melt the product.
[0071] In summary, the hot melt equipment 100 of this utility model has a pressure sensing component 150 installed below the fixture assembly 140. The pressure sensing component 150 includes a base and a pressure sensor 151 installed at the bottom of the base and electrically connected to the controller. The pressure sensor 151 located at the bottom of the fixture assembly 140 can more directly provide feedback on the hot melt pressure of the product. A driver 111 electrically connected to the controller is provided to connect to and drive the hot melt assembly 130. Therefore, the controller can obtain the pressure of the pressure sensor 151 in real time and control the driver 111 to adjust the downward stroke according to the obtained pressure, so that the downward stroke can adapt to the assembly differences, thereby ensuring the specific consistency of the hot melt effect of products with assembly differences and improving product quality.
[0072] The structures of other parts of the hot-melting equipment 100 involved in this utility model are all conventional structures well known to those skilled in the art, and will not be described in detail here.
[0073] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
