Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and more specifically, to a circuit board flattening mold for a new energy vehicle LED display screen. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. When processing the circuit board of the LED display, in order to facilitate the etching of the circuit on the surface of the circuit board, it is necessary to first use a leveling mold to level the circuit board.

[0003] After searching, a LED display circuit board leveling mold with announcement number CN208050629U includes an upper mold and a lower mold. The upper mold and the lower mold are provided with cavities with the same shape as the LED display circuit board. The upper mold and the lower mold are provided with heating mechanisms. Through the above settings, the semi-finished product of the circuit board is processed by the leveling mold. The dimensional accuracy of the mold is much higher than the accuracy of manual knocking. The mold is placed in a hydraulic press. The circuit board after drilling and milling is leveled through the high pressure of the hydraulic press and the heating effect of the heating mechanism. The leveling effect is good and the flatness value is small. Heating mechanisms are provided in both the upper mold and the lower mold to ensure that the circuit board is heated evenly as a whole, the circuit board softens to a certain extent when heated, and the residual stress after the shape changes under pressure is small, which can increase the service life of the circuit board. The cavity in the leveling mold can ensure accurate flattening of the circuit board to avoid damage to the structure on the circuit board.

[0004] However, the above-mentioned leveling mold is heated during the mold closing process, and the circuit board in a high-temperature state is directly taken out after hot pressing and subsequently cooled. There are safety hazards in the taking process. At the same time, the circuit board in a high-temperature state is subsequently directly cooled, and the heat energy cannot be fully utilized, resulting in heat energy loss. Summary of the invention

[0052] For example, see Figure 1-19 , the present invention provides the following technical solutions:

[0054] The working principle of the first embodiment is as follows: after the hot pressing forming is completed, the upper mold 3 is controlled to rise and separate from the molding cavity 9. During this process, the connecting rope is straightened, and the upper mold 3 continues to rise, pulling the rotating member 14 and the connecting member 15 to rotate synchronously through the connecting rope, thereby driving the annular seat 8 to rotate along the inner wall of the fixed plate 4, realizing the automatic replacement of each component molding cavity 9, and improving the leveling efficiency.

[0055] During the rotation process, the circuit board after hot pressing falls into the heat exchange box 11 through the discharge chute 10, and the exhaust fan 46 is controlled to start to transport the heat in the circuit board through the L-shaped air pipe 12 into the circuit board between the insulation board 56 and the hot pressing box 2, so as to achieve the cooling of the circuit board after hot pressing. At the same time, the circuit board to be hot pressed is preheated, which improves the uniformity of subsequent hot pressing of the circuit board, thereby improving the subsequent hot pressing efficiency.

[0056] For example 2, please refer to Figure 1-19The second embodiment is improved on the basis of the first embodiment as follows. Specifically, a sealing door is hingedly provided on one side of the hot press box 2; an electric heating plate 16 is fixed to the inner bottom surface of the hot press box 2; a support plate 17 is fixed between the inner bottom surfaces of the two avoidance openings 6; the upper mold 3 includes an electric push rod 18 fixedly installed on the top of the hot press box 2; a lifting plate 19 slidably arranged inside the hot press box 2 is fixed at the telescopic end of the electric push rod 18; an upper mold 20 plugged with the molding cavity 9 is fixed to the bottom surface of the lifting plate 19.

[0057] An annular groove 21 is provided on the outer peripheral side of the fixed ring 13; an annular rail is fixed on the inner wall of the annular groove 21; the rotating member 14 includes an arc plate 22 rotatably arranged in the annular groove 21; an arc groove that slides with the annular rail is provided on the surface of the arc plate 22; an arc spring 23 is fixed between the arc plate 22 and the annular groove 21; an avoidance hole 24 is provided on the bottom surface of the lifting plate 19; a lifting ear 25 is installed on the top of the avoidance hole 24; a guide rope tube 26 is provided on the side of the hot press box 2; a connecting rope that passes through the guide rope tube 26 is connected between one end of the arc plate 22 and the lifting ear 25.

[0058] Two ear plates 35 are fixed to the outer peripheral side of the fixing ring 13 above the annular groove 21; an arc guide plate 36 is fixed between the two ear plates 35; the bottom surface of the arc guide plate 36 is an inclined surface; an extension plate 27 is fixed to the outer peripheral side of the arc plate 22; a guide hole 28 is provided on the surface of the extension plate 27; the connecting piece 15 includes a sleeve 29 slidably arranged in the guide hole 28; and sockets 30 that are plugged into and matched with the sleeve 29 are evenly provided on the surface of the annular seat 8.

[0059] A slide rod 31 is slidably arranged inside the sleeve 29; a baffle 32 is fixed to the top of the slide rod 31; a support spring 33 is fixed between the baffle 32 and the extension plate 27; a return spring 34 is connected between the slide rod 31 and the inner bottom surface of the sleeve 29; a ball head 37 adapted to the inclined bottom surface of the arc guide plate 36 is fixed on the surface of the baffle 32.

[0060] An arc column 38 coaxial with the fixed ring 13 is fixed on the side of an ear plate 35; a sliding portion 39 is slidably arranged on the arc column 38; the sliding portion 39 includes an arc tube 40 slidably arranged on the arc column 38; a connecting spring 41 sleeved on the arc column 38 is connected between the arc tube 40 and the ear plate 35; a vertical rod 42 is fixed to the bottom surface of the arc tube 40; a pressure plate 43 that slides in contact with the surface of the annular seat 8 is fixed to the bottom end of the vertical rod 42.

[0061] Working principle of the second embodiment:

[0062] Note: The position directly above the support plate 17 inside the hot press box 2 is the hot press station, the position directly above the unloading chute 10 inside the fixed plate 4 is the unloading station, the position directly opposite the hot press station inside the fixed plate 4 is the loading station, and the position between the hot press station and the loading station inside the fixed plate 4 is the preheating station (such as Fig.13 as shown).

[0063] In the hot pressing state, the sleeve 29 is inserted into the corresponding socket 30 at the blanking station. At this time, the support spring 33 is in a compressed state, and the ball head 37 is pressed tightly against the lowest part of the inclined bottom surface of the arc guide plate 36 under the elastic force of the support spring 33. The reset spring 34 is in a normal state. At this time, the circuit board placed in the hot pressing station has completed hot pressing, and the connecting rope is in a relaxed state (such as Figure 14-15 shown)

[0064] By controlling and starting the electric heating plate 16, the temperature inside the hot press box 2 is increased, and by controlling and starting the electric push rod 18 to extend, the lifting plate 19 is driven to descend along the inner wall of the hot press box 2, so that the upper mold 20 descends and is inserted into the corresponding molding cavity 9, and the circuit board in the molding cavity 9 is subjected to hot pressing molding operation.

[0065] After the hot pressing is completed, the electric push rod 18 is controlled to contract and start, so that the lifting plate 19 rises along the inner wall of the hot pressing box 2, so that the upper mold 20 is separated from the circuit board after hot pressing. During this process, the connecting rope is straightened and the lifting plate 19 continues to rise, thereby pulling the arc plate 22 to rotate along the annular groove 21 through the connecting rope, and the arc spring 23 is compressed. Since the sleeve 29 is plugged into the corresponding socket 30 at the unloading station, the arc plate 22 drives the annular seat 8 to rotate through the sleeve 29 during the rotation process. After the annular seat 8 rotates 90°, the electric push rod 18 stops working, and the automatic replacement of each component cavity 9 is completed.

[0066] The cam 37 is pressed against the top of the support 33 and the cam 37 is pressed against the bottom of the support 33. The cam 37 is pressed against the top of the support 33 and the cam 37 is pressed against the bottom of the support 33.

[0067] The electric push rod 18 is controlled to descend, and the arc plate 22 is driven to rotate in the opposite direction under the elastic reset force of the arc spring 23, so that the ball head 37 slides from the highest point to the lowest point of the inclined bottom surface of the arc guide plate 36. During this process, the sleeve 29 slides and fits on the surface of the annular seat 8, and the support spring 33 and the reset spring 34 are compressed. When the sleeve 29 slides to the top of the corresponding socket 30 at the unloading station, the sleeve 29 is driven to be inserted into the corresponding socket 30 under the elastic reset force of the reset spring 34. The reset spring 34 is in a normal state and the support spring 33 is in a compressed state. At this time, one end of the arc plate 22 is pressed on the pressure sensor 48, and the pressure sensor 48 transmits a signal to the controller 47. The controller 47 controls the electromagnetic suction cup 57 to lose power (such as Figure 16-19 as shown).

[0068] The above operation process completes the sequential replacement of the positions of the corresponding molding cavities 9 at the hot pressing station, unloading station, loading station and preheating station, realizing the integrated production of circuit board loading, preheating, hot pressing, unloading and cooling and conveying, which optimizes the process and improves the efficiency of circuit board leveling.

[0069] For example 3, please refer to Figure 1-19 The third embodiment is improved on the basis of the second embodiment as follows. Specifically, a plurality of heat dissipation holes 44 are evenly provided on the side surface of the fixed plate 4 between the L-shaped air delivery pipe 12 and the hot press box 2; a plurality of ventilation slots 45 are provided at one end of the heat exchange box 11; an exhaust fan 46 is installed on the top of the heat exchange box 11; a controller 47 is installed on the side surface of the heat exchange box 11; a pressure sensor 48 is installed on the side surface of the fixed ring 13; the input end of the controller 47 is electrically connected to the pressure sensor 48, and the output end thereof is electrically connected to the electric push rod 18, the electric heating plate 16 and the exhaust fan 46 respectively.

[0070] A high temperature resistant belt roller 49 is symmetrically provided between the inner walls of the heat exchange box 11 and rotates therethrough; a high temperature resistant belt 50 is provided for transmission between the two high temperature resistant belt rollers 49; a servo motor 51 electrically connected to the output end of the controller 47 is installed on the side of the heat exchange box 11; the output end of the servo motor 51 is fixedly connected to the end of a high temperature resistant belt roller 49;

[0071] A discharge port 52 is provided at the other end of the heat exchange box 11; a sealing plate 53 is slidably arranged between the inner walls of the discharge port 52; a bearing plate 54 is fixed to the side of the discharge port 52; the sealing member 7 includes a top cover plate 55 fixedly installed on the top of the fixed disk 4; a heat insulation plate 56 is provided on the bottom surface of the top cover plate 55; an electromagnetic suction cup 57 electrically connected to the output end of the controller 47 is installed on the bottom surface of the top cover plate 55; a feeding port 58 is provided on the surface of the top cover plate 55.

[0072] Working principle of the third embodiment:

[0073] During the rotation process, the circuit board after hot pressing falls onto the high temperature resistant belt 50 through the discharge chute 10, and the controller 47 controls the start of the exhaust fan 46 to transport the heat in the circuit board through the L-shaped air pipe 12 into the circuit board between the insulation board 56 and the hot pressing box 2 (i.e., the circuit board in the preheating station), thereby cooling the circuit board after hot pressing. At the same time, the circuit board to be hot pressed is preheated, which improves the uniformity of subsequent hot pressing of the circuit board, thereby improving the subsequent hot pressing efficiency.

[0074] By controlling and starting the servo motor 51, a high temperature resistant belt roller 49 is driven to rotate, thereby driving the high temperature resistant belt 50 to transmit. After a period of time, the sealing plate 53 is opened, and the circuit board of the high temperature resistant belt 50 is transported to the carrier plate 54 through the discharge port 52.
