Description

Technical Field

[0001] This utility model relates to the field of hot press welding equipment technology, and in particular to a hot press welding equipment. Background Technology

[0002] Existing hot-press welding equipment, during production, based on the fact that the lens barrel consists of multiple lenses, which are hot-melt welded to the lens frame, and then the multiple lens and frame assemblies are assembled into the lens barrel, has the following two problems: Problem 1: Currently, the welding process uses ordinary heating tubes to conduct heat through copper components for hot-melt welding. The disadvantages are slow heating, inaccurate temperature control, resulting in poor welding effect, uneven surface, and frequent adhesion and stretching phenomena at the welded parts; Problem 2: Since the welding depth affects the overall effect of the lens barrel, the current height measurement after welding is done through periodic sampling. This means that lens and frame assemblies with welding depth problems in the periodic sampling interval cannot be detected in time. The defective welding depth is only discovered during the sampling inspection, resulting in a high product defect rate and requiring full measurement of all products in the sampling interval. If the sampling does not detect the defective products, some defective products will flow to the next process. Based on the above problems, there is a need to develop a hot-melt welding device with stable temperature control, good welding appearance, less adhesion (rough edges), and real-time measurement of the welding depth. Based on this, a hot-press welding device is proposed to solve the above problems. Utility Model Content

Before the welding head is raised, it is rapidly cooled by airflow to a specified temperature before being raised, reducing the problem of high-temperature bonding.

[0011] By employing the above technical solution, this utility model provides a hot-press welding device, which has at least the following beneficial effects:

[0012] 1. This utility model efficiently solves the problem of heating and cooling control, eliminating the issue of high-temperature bonding. It adopts the low-voltage, high-current heating technology of a pulse welding machine, which has significant advantages over traditional heating tubes in terms of rapid heating speed and stable temperature control. The pulse current acts directly on the welding head to achieve rapid heating, avoiding the inefficiency caused by slow heat conduction in traditional heating tubes. Combined with real-time temperature sensing by thermocouples and precise control by PLC program, it ensures that the temperature fluctuation range of the welding head is extremely small, solving the problem of unstable temperature in traditional heating methods. After heat melting, the airflow enters the hollow structure inside the welding head through the air blowing bend, achieving rapid cooling to the specified temperature, and the welding head has already cooled down before it rises. By utilizing the instantaneous nature of pulse heating and the high efficiency of forced airflow cooling, the risk of burrs being pulled out on the bonding surface of the welding head and the frame due to prolonged high-temperature contact is fundamentally reduced, improving the purity and structural stability of the product's weld interface.

[0013] 2. This utility model enables full-process online measurement, eliminating quality risks caused by sampling intervals. Through the linkage between the length measuring mechanism and the PLC program, a closed-loop control system of real-time measurement-feedback-judgment is constructed, completely solving the lag problem of traditional sampling inspection: The length measuring process is triggered before and after product welding. When a section moves to the measuring position, the slide cylinder drives the resin pressure head to press down, and the length measuring sensor collects the assembly dimension data of the lens and frame in real time. The length measuring counter displays the value immediately and compares it with the set range for OK / NG. If the measurement result exceeds the tolerance range, the system immediately alarms and stops, preventing defective products from flowing into subsequent processes. After welding, a second inspection is conducted to ensure that the welding depth of each product meets the requirements, significantly reducing the rework or scrap rate caused by untimely measurement, and upgrading quality control from "post-inspection" to "full-process online monitoring".

[0028] Working principle: The forward and backward moving mechanism 12 mainly realizes the switching mechanism's first-stage moving measurement position and second-stage moving pulse hot melt welding position. The piston rod of the first-stage cylinder is fixed with a floating joint. One end of the floating joint is fixed to the connecting block 1220. The connecting block 1220 is fixed to the upper left of the slide rail plate 2. The connecting block 2212 is fixed to the right side of the slide rail plate 2. The connecting plate 2 is fixed with a spring rod 1214. Below the spring rod 1214 is a spring rod stop 1213, and the spring rod stop 1213 is fixed with a stop bolt. The spring rod 1214 passes through the middle of the switching mechanism connecting block 1219 with clearance fit. The front side of the switching mechanism connecting block 1219 is fixed with a stop bolt. The other end of the spring rod 1214 has a compression spring 1209 and a spring bushing 1218. The front end of the spring bushing 1218 is locked with a nut. On the spring rod 1214, the spring 1209 is compressed. Under the action of the spring 1209, the switching mechanism connecting block 1219 is pressed towards the spring rod stop block 1213, so that the switching mechanism and the spring rod stop block 1213 are always in a relatively fixed position. The second slider plate is fixed on the second slider 1221 of the linear slide rail 1201, and the other end of the first moving cylinder is fixed on the first slider plate. The first slider plate is fixed on the first slider of the linear slide rail 1201. The front side of the first slider plate is fixed with the third connecting block 1223. The third connecting block 1223 is connected to the piston rod of the second moving cylinder through a floating joint. The switching mechanism is fixed above the slider of the second linear slide rail 1207. The second moving cylinder is fixed on the base plate. The front of the base plate is provided with the third buffer mechanism 1206 for buffering the second forward movement.

[0029] One-stage movement: The piston rod of the cylinder moves, which drives the connecting block 1220 to move through the floating joint, thereby moving the slider plate 2, which in turn moves the connecting block 2212. Under the compression force of the spring 1209, the switching mechanism moves above the slider of the linear slide rail 2207. (The spring rod 1214 is fixed on the connecting block 2212 and has a clearance fit with the shaft hole of the connecting block 1219 of the switching mechanism, and the compressed spring is pressed tightly.)

[0030] Two-stage movement: The piston rod of the second-stage cylinder moves, which drives the connecting block 1223 to move through the floating joint. The connecting block 1223 drives the slider plate to move, thereby driving the first-stage cylinder to move. The switching mechanism follows the first-stage cylinder to move. There is a buffer mechanism to buffer the movement before it reaches the end position during forward and backward movement.

[0031] The switching mechanism 9 includes a base plate, a linear slide rail 905, a stop block 904, an adjusting screw assembly 903, a stop bolt 906, a switching cylinder, and a fixing assembly. The base plate is fixed to the slider of the linear slide rail 1207 of the moving mechanism. A connecting block 901 is fixed below the base plate. The slide rail is fixed to the base plate, and there are stop blocks 904 on both sides. The stop blocks 904 are equipped with adjusting screw assemblies 903. The slide plate 911 is fixed to the two sliders of the slide rail. The slide plate 911 has two stop bolts 906 on its side and rear end, which are used to position the slide plate 911 in conjunction with the adjusting screw assembly 903. The switching cylinder 910 is open. The cylinder fixing plate 909 and the L-shaped cylinder fixing piece 908 are fixed to the front side of the base plate. The cylinder piston rod is connected to the slide plate 911 through the slide plate connecting block 907. The piston rod and the slide plate connecting block 907 are locked from the front and have a clearance fit from the side to prevent installation and processing deviations from causing the piston rod and the slide to be at an angle and jam. When the piston rod of the switching cylinder 910 moves, it drives the slide plate connecting block 907 to move. The slide plate connecting block 907 pulls the slide plate 911 to move. When it is in place, the stop screw is pressed against the adjusting screw assembly 903. The adjusting screw assembly 903 adjusts the left and right positions, thereby realizing the adjustment of the left and right positions of the fixture 15.

[0032] Fixture and Product: Fixture pad 20 and fixture 15 are positioned at the center by a circular concave-convex joint, and one end is precisely positioned by a pin engaging with a hole; fixture 15 has multiple holes on its side, one of which is left open for vacuum connection hole 16, and the other holes are blocked to achieve vacuum adsorption of the product; the groove on the top of fixture 15 is designed to conform to the shape of the lens frame 18, so that the lens 17 is centered and the groove positioning will not move; there are pick-and-place slots 19 on the front and back sides, which facilitate the placement of the product and its removal after welding;

[0033] The hot-pressing mechanism 11 includes a column 1101, a cylinder, a connecting block, a hot-melt assembly, a linear slide rail, and a positioning assembly; the device body 1; the lifting cylinder 1105 descends, while the buffer cylinder 1104 remains in an ascending state, reducing the descent speed of the lifting cylinder 1105. Through the floating joint 1116, the flange connecting block 1107 descends, causing the lower L-plate 1111 to descend on the linear slide rail 1113. The hot-melt assembly is fixed to the lower L-plate 1111 by the heat insulation block 1118. Therefore, the hot-melt assembly descends to the position set by the lower positioning assembly 1110 and stops descending; hot-melt, air blowing is activated, and the fusion head 1122 descends to the set temperature. After the hot melt is completed, the lifting cylinder 1105 rises, the lower L-plate 1111 rises, and the hot melt assembly rises accordingly. The air inlet of the buffer cylinder 1104 is connected to only one side and is always in a state of rising with air. It plays a buffering role when the lifting cylinder 1105 descends. The positioning baffle 1103 and the adjusting screw assembly 1102 mainly adjust the height position of the upper L-plate 1114. The heat insulation block 1118 is made of bakelite and has two functions: insulation and heat insulation. The lower positioning assembly 1110 fixes the descending position of the lower L-plate 1111, that is, controls the descending height of the welding head 1122, thereby controlling the hot melt depth. The connecting airflow is used to blow air onto the welding head 1122 for rapid cooling. The airflow first enters the oil mist separator, then the solenoid valve, then the filter, and finally the air blowing elbow 1123 to ensure clean airflow and prevent the airflow from contaminating the product. The positioning component 1109 mainly adjusts the front and rear positions of the switching mechanism at the welding position, aiming to adjust the relative position of the product and the welding head 1122. The hot melt connector 1120 consists of two semi-cylindrical copper parts and an intermediate isolation plate, mainly used to connect with the pulse pressure welding machine 8 and accurately position the welding head 1122. It is connected to the front soft copper busbar 14 through two cross copper parts on both sides. The soft copper busbar 14 is fixed on the adapter plate 13, and the adapter plate 13 is then connected to the pulse pressure welding machine. The machine is connected to 8; the upper end of the hot melt connector 1120 is positioned by the central circular protrusion and the groove of the heat insulation block 1118, and is locked by the peripheral screws; the lower end groove and protrusion are positioned by matching with the welding head 1122, and the multi-hole pin is locked and positioned with the welding head 1122. The welding head 1122 and the notch of the hot melt connector 1120 are vertically aligned; the isolation plate is made of bakelite and is used to isolate the two copper parts electrically. When heated, the connector will not be heated first, but the welding head 1122 will be heated first and the welding head will be conductive; the two semi-cylindrical copper parts are locked and connected by high-temperature resistant plastic screws at the four screw holes as shown above. There is a hole between the two copper parts and the middle of the isolation plate to facilitate airflow into the welding head 1122;

[0034] The welding head 1122 has an upper end that matches the inner and outer circular concave-convex parts of the heat fusion connector 1120, with corresponding notches. It is secured with a screw and a pin hole. A thermocouple 1121 is welded to the lower end to sense the temperature in real time. The inner surface of the welding head 1122 has a beveled surface that corresponds to the welding surface of the frame 18. Welding involves heat-melting the welding surface of the frame 18. After welding, the frame 18 encloses the lens 17. The welding head 1122 has a hollow center to allow airflow to enter from the heat fusion connector 1120 and cool down quickly. This design has the front end connected together and the middle and rear ends hollowed out, so the lower end heats up first during heating.

[0035] Length measuring mechanism 10 includes a slide cylinder 1018, a length measuring sensor 1017, a connecting plate, a connecting block, a guide rod, a guide block 1003, a spring, a positioning assembly, and an adjusting nut. When the slide cylinder 1018 descends, the connecting plate descends with it, and the guide block 1003 descends with the connecting plate, causing the adjusting rod 1004 to descend as well. This continues until the resin pressure head 1005 below the adjusting rod 1004 contacts the product. The adjusting rod 1004 then slides upwards, compressing the spring 1007 and pressing against the adjusting plate 1014, thus applying an upward force to the guide block 1003. The upper end of the adjusting rod 1004 then pushes the measuring sensor... The telescopic head 1019 of the length sensor 1017 retracts, the length measuring counter 4 receives the signal, displays the value, and determines whether it is within the range. If it is within the range, a green "OK" light appears; if it is outside the range, a red "NG" light appears and an alarm sounds. After completion, the cylinder rises, the guide block 1003 rises with the connecting plate, the compression spring 1007 is released, and the resin pressure head 1005 leaves the product. The slide cylinder 1018 is fixed on the length measuring fixing block 1001, the upper end of the connecting plate is fixed on the cylinder sliding block, and the guide block 1003 is fixed on the lower end of the connecting plate. The three holes of the guide block 1003 are respectively equipped with linear bearings 1020, and the bearings are fixed with retaining rings. At the end, a guide rod 1010 and a guide rod 1012 are installed on each of the left and right bearings. A connecting block 1016 is fixed to the upper end of guide rod 1010, and a length measuring sensor 1017 is fixed to the other end of connecting block 1016. A connecting block 2015 is fixed to the upper end of guide rod 1010 above the bearing, and a connecting block 3013 is fixed to the lower end. A connecting block 2015 is fixed to the upper part of guide rod 1012 above the bearing, and a connecting block 3013 is fixed to the lower part of the bearing. An adjusting rod 1004 passes through the middle bearing of guide block 1003, and a connecting block 2015 passes through the upper part of adjusting rod 1004. An adjusting nut 1008 is fixed above the adjusting rod 1004 for fine-tuning the height of the adjusting rod 1004. A connecting bushing 1006 is fixed below the adjusting rod 1004. A resin pressure head 1005 is fixed below the connecting bushing 1006. A retaining ring and a washer are located above the connecting bushing 1006 to hold the compression spring 1007 in place. The compression spring 1007 passes through the adjusting rod 1004 and is located between the adjusting plate 1014 and the washer. The adjusting plate 1014 is fixed on the guide block 1003. The adjusting plate 1014 mainly adjusts the tightness of the compression spring 1007 so that the resin pressure head 1005 presses down with appropriate force.

[0036] Place the product with lens 17 installed onto fixture 15. Place both hands on the photoelectric sensor areas on the left and right sides. The program receives the start signal and checks whether the temperature has risen to the set temperature (e.g., 200℃) according to the pulse welding machine 8. If the temperature is reached, the PLC program drives the solenoid valve to actuate, and the cylinder rod of the first stage cylinder retracts, moving the switching mechanism and the product to the measurement position. The sensor illuminates to confirm the cylinder is in position, and the measurement program is started. The slide cylinder 1018 descends, causing the length measuring mechanism 10 to press down. The resin pressure head 1005 touches the product, and the pressure is in place. The value is displayed and compared with the upper and lower limits of the set range tolerance. If it is within the range, the length measuring counter 4 lights up green, indicating OK and pass; otherwise, it lights up red (NG), the buzzer sounds an alarm, and the process stops. If OK, the cylinder returns, causing the length measuring mechanism 10 to return. Once the return sensor is in position, the second stage movement program is started. The second stage cylinder... The switching mechanism and product are moved to the welding position. When the welding position sensor light illuminates, a return signal is received, and hot pressing is initiated. The lifting cylinder 1105 drives the hot pressing mechanism 11 to descend, and the welding head 1122 contacts the welding surface to begin hot melting. When the hot melting time is up, air blowing is initiated to cool the welding head 1122 to a set temperature, such as 100°C. The lifting cylinder 1105 then drives the hot pressing mechanism 11 to return to its original position. When the return position sensor light illuminates, the program is initiated, and the second-stage cylinder retracts. When the second-stage cylinder returns to its original position, the second-stage cylinder returns to its original position, and the second-stage cylinder returns to its original position, and the measurement program is initiated. The measurement process is the same as before. If the measurement is within the set range, the length counter 4 lights up green, indicating OK. If the measurement is outside the set range, the red light indicates NG, the buzzer sounds an alarm, and the process stops. If the measurement is OK, the next step is executed. The length measuring mechanism 10 returns, the return position light illuminates, and the first-stage cylinder rod extends, driving the switching mechanism and product back to the initial position.
