[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] Embodiment 1, as Figure 1-2As shown, an adjustable pressurizing device for producing flexible circuit boards comprises a workbench 1, a hydraulic cylinder 2 is provided at the middle part of the lower end of the workbench 1, the output end of the hydraulic cylinder 2 passes through the middle part of the lower end of the workbench 1 and is fixedly connected with a pressurizing mechanism 8, a bearing mechanism 3 is symmetrically provided at the upper end of the workbench 1, a connecting shaft 6 is commonly provided between the opposite surfaces on the right sides of the two bearing mechanisms 3, a motor 5 is provided at the right side of the lower end of the workbench 1, a transmission wheel 7 is provided at the output end of the motor 5 and the front side of the outer surface of the connecting shaft 6, the two transmission wheels 7 are connected by belts, and a storage group 4 is provided at the right end of the workbench 1.

[0020] It should be noted that the specific installation method of the hydraulic cylinder 2 and the motor 5, the circuit connection method and the control method in the present invention are all conventional designs and are conventional design means for designers.

[0021] First, the entire device is supported by the workbench 1, and the hydraulic cylinder 2 and the motor 5 are started at the same time, so that the motor 5 drives the transmission wheel 7 and the connecting shaft 6 to rotate through the belt, and then drives the front and rear symmetrical carrying mechanism 3 to operate, and the hydraulic cylinder 2 drives the pressurizing mechanism 8 to pressurize the flexible circuit board in the cooperation of the carrying mechanism 3, and by adjusting the pressurizing mechanism 8, in the cooperation of the hydraulic cylinder 2, the pressure on the flexible circuit board can be changed according to the processing needs. At the same time, the pressurizing mechanism 8 can make the pressurized flexible circuit board enter the storage group 4 for cooling and storage, and there is no need to manually pick up the flexible circuit board after pressurization, thereby improving the working efficiency of the device.

[0022] In order to change the pressure on the flexible circuit board according to the needs, such as Figure 3 As shown, the pressurizing mechanism 8 includes three auxiliary rods 81, the lower end of the auxiliary rod 81 located in the middle is fixedly connected to the output end of the hydraulic cylinder 2, and the lower ends of the three auxiliary rods 81 all pass through the middle of the upper end of the workbench 1, and the upper ends of the three auxiliary rods 81 are jointly provided with a cross pressure plate 82, and the middle of the upper end of the cross pressure plate 82 is provided with a motor 2 83, and the middle of the upper end of the cross pressure plate 82 is provided with a groove, and the motor 2 83 is installed in the inner cavity of the groove, and the front and rear sides of the cross pressure plate 82 are provided with rotating screws 85, and the front and rear ends of the upper end of the cross pressure plate 82 are provided with rotating screws 85. There are through rotating holes on both sides, and the rotating screw 85 can rotate in the through rotating holes. The output end of the motor 83 and the upper ends of the two rotating screws 85 are provided with a transmission wheel 84. The upper end of the rotating screw 85 located on the rear side is composed of two transmission wheels 84, and the upper transmission wheel 84 is connected to the output end of the motor 83 by a belt, and the lower transmission wheel 84 is connected to the upper end of the front rotating screw 85 by a belt. A pressing group 86 is provided on the lower side of the outer surface of the two rotating screws 85.

[0023] It should be noted that the specific installation method of the motor 2 83 and the circuit connection method and control method in the present invention are all conventional designs and are conventional design means for designers.

[0024] When the hydraulic cylinder 2 is started, the cross pressure plate 82 is driven by the auxiliary rod 1 81 located in the middle, and with the cooperation of the rotating screw 85, the pressing groups 86 on the front and rear sides are driven to pressurize the flexible circuit board. If the pressure intensity needs to be changed, the motor 2 83 needs to be started, and the rotating screws 85 on the front and rear sides of the cross pressure plate 82 are driven to rotate with the cooperation of the belt. The rotation of the rotating screws 85 on both sides drives the pressing group 86 to move vertically up and down to a suitable position, changing the distance between the pressing group 86 and the cross pressure plate 82, and then starting the hydraulic cylinder 2, so that the pressing group 86 presses the flexible circuit board, thereby changing the pressure intensity.

[0025] Further explanation, such as Figure 4 As shown, the two pressing groups 86 each include a connecting seat 861 meshingly connected to the lower side of the outer surface of the rotating screw 85, and the upper ends of the two connecting seats 861 in the horizontal direction are symmetrically provided with auxiliary rods 862, and the upper ends of the two auxiliary rods 862 on the same side pass through the lower end to the upper end of the cross pressure plate 82, and through holes are opened at the corresponding vertical positions of the cross pressure plate 82 and the four auxiliary rods 862, and the through holes are adapted to the auxiliary rods 862, and the lower ends of the two connecting seats 861 are provided with a pressure plate component 863, and the ends of the two pressure plate components 863 away from each other are provided with a clamping strip component 864, and the clamping strip component 864 is fixedly connected to the pressure plate component 863 by bolts and can be disassembled as needed.

[0026] In detail, the connecting seat 861 is adapted to the rotating screw 85. When the rotating screw 85 rotates, the connecting seat 861 drives the pressure plate component 863 to move in the vertical direction through the cooperation of the auxiliary rod 862 and the through hole on the cross pressure plate 82, thereby changing the pressure intensity. The pressure plate component 863 includes a heating block, which is used to heat the flexible circuit board when the pressure plate component 863 presses the flexible circuit board. This will make the flexible circuit board fit more closely, thereby improving the pressurization efficiency of the device. The installed card strip component 864 is used in conjunction with the bearing group 341 in the bearing mechanism 3.

[0027] Embodiment 2: Based on the embodiment 1, this embodiment cooperates with the pressurizing mechanism 8 to complete the pressurization and automatic transportation of the flexible circuit board. Figure 4 As shown, the two supporting mechanisms 3 each include a supporting plate 32 fixedly connected to the upper end of the workbench 1, rollers 33 are provided on the left and right sides of the two supporting plates 32, and the outer surfaces of the two rollers 33 on the same side are commonly wound and connected with a conveyor belt 31, and a supporting component 34 is provided on the upper end of the two supporting plates 32, which is located in the middle of the opposite surfaces of the two rollers 33 on the right side and is fixedly connected to the front and rear ends of the connecting shaft 6 respectively.

[0028] When the motor 5 is started, with the cooperation of the belt, the connecting shaft 6 and the transmission wheel 7, the two rollers 33 on the right side are driven to rotate on the support plates 32 on the same side, thereby rotating the conveyor belt 31, and pressurizing the flexible circuit board on the bearing component 34 through the pressure plate component 863. After pressurization, with the cooperation of the clamping strip component 864, the bearing component 34 is adjusted so that the flexible circuit board on the bearing component 34 slides onto the conveyor belt 31, and is then transported to the storage group 4 by the conveyor belt 31.

[0029] Further explanation, such as Figure 6 As shown, the two bearing components 34 both include left-right symmetrical support frames 342, and mounting grooves 343 are provided on the upper sides of the opposite surfaces of the two support frames 342 on the same side. A bearing group 341 is commonly provided in the inner cavities of the two mounting grooves 343 on the same side, and crank handles 344 are provided on the left and right sides of the bearing group 341 on the same side, and a hole groove matched with the crank handle 344 is provided in the middle of the upper end of each support frame 342.

[0030] In detail, the support frame 342 is installed at the upper end of the support plate 32, which does not affect the transportation of the conveyor belt 31. The load-bearing group 341 is installed in the inner cavity of the installation groove 343. The load-bearing group 341 is penetrated by a crank 344. The crank 344 is rotated to install the load-bearing group 341 on the two support frames 342 on the same side. The load-bearing group 341 can be replaced according to the size of the flexible circuit board.

[0031] Further explanation, such as Figure 7 and Figure 8 As shown, the two bearing groups 341 each include a removable plate 3411 which is slidably connected to the inner cavities of the two mounting grooves 343 on the same side, the upper ends of the two removable plates 3411 are provided with left-right symmetrical limiting holes 3412, the inner cavities of the two removable plates 3411 are provided with a number of support groups 3413, the two removable plates 3411 are provided with a number of fixed plates 3414 on the side away from each other, a spring 2 3415 is provided in the middle of the lower end of the several fixed plates 3414 on the same side, and a support rod 3416 is provided on the right side of the lower end of the several fixed plates 3414 on the same side.

[0032] In detail, the crank handle 344 passes through the inner cavity of the limiting hole 3412, so that the removable plate 3411 is installed in the inner cavity of the mounting groove 343, the removable plate 3411 is fixed, and the flexible circuit board is placed on a plurality of support groups 3413, and the flexible circuit board at the upper end of the support group 3413 is pressurized by the pressure plate component 863, and the pressure plate component 863 drives the card strip component 864 to move downward, and the support rod 3416 cooperates with the fixed plate 3414 to support the support group 3413, so that the support group 3413 will not rotate during the pressurization of the flexible circuit board. After the pressurization, the pressure plate component 863 drives the card strip component 864 to move upward, and the card strip component 864 drives the support group 3413 to pull the spring 2 3415 to rotate. At this time, the flexible circuit board on the support group 3413 slides along the support group 3413 to the conveyor belt 31, and a pressure sensor is provided on the removable plate 3411 for detecting pressure changes.

[0033] Further explanation, such as Fig. 9 As shown, the several support groups 3413 all include a bearing platform 34131 rotatably connected to the inner cavity of the removable plate 3411, the ends of the several bearing platforms 34131 close to the fixed plate 3414 all penetrate the inner cavity of the removable plate 3411 and are fixedly connected with a fixing box 34134, the right sides of the upper ends of the several fixing boxes 34134 are respectively fixedly connected to the lower ends of the several spring twos 3415, the right walls of the inner cavities of the several fixing boxes 34134 are provided with a spring one 34133, the left ends of the several spring one 34133 are provided with an arc-shaped slider 34132, and the outer surfaces of the several arc-shaped sliders 34132 are slidably connected to the inner cavities of the several fixing boxes 34134.

[0034] In detail, the second spring 3415 is fixedly connected to the right side of the upper end of the fixing box 34134 at the same position, and the support rod 3416 is against the right side of the upper end of the fixing box 34134 in the initial state, and the support rod 3416 is located on the right side of the second spring 3415, and then the clamping strip component 864 slides downward to compress the arc-shaped slider 34132, so that when the arc-shaped slider 34132 compresses the spring 1 34133 and enters the inner cavity of the fixing box 34134, it will not drive the bearing platform 34131 to rotate, and when the clamping strip component 864 moves down to a suitable position, the spring 1 34133 Under the action of elastic force, the arc-shaped slider 34132 pops out and presses against one side of the clamping strip component 864. After the pressure plate component 863 presses the flexible circuit board on the supporting platform 34131, the clamping strip component 864 moves upward to drive the arc-shaped slider 34132 and the fixed box 34134 to rotate, and then drives the supporting platform 34131 to rotate to a suitable position. Under the action of gravity, the flexible circuit board will slide along the supporting platform 34131 to the conveyor belt 31. A number of latch pins are installed on the clamping strip component 864, and the number of latch pins are adapted to the number of arc-shaped sliders 34132.

[0035] In order to achieve cooling and storage of flexible circuit boards, Fig.10 As shown, the storage group 4 includes a connecting inclined plate 41 fixedly connected to the right end of the workbench 1, and a front-to-back symmetrical bellows 42 is provided at the right end of the connecting inclined plate 41. A feed port 45 is provided on the upper side of the left end of the two bellows 42, a storage box 43 is provided on the lower side of the inner cavity of the two bellows 42, and a cold air component 44 is provided on the top wall of the inner cavity of the two bellows 42.

[0036] It should be noted that the cold air component 44 includes a ventilation plate and an air cooler. The specific installation method of the air cooler, the circuit connection method and the control method are all conventional designs, which are conventional design means of designers. They only need to meet the purpose of the air cooler cooling the flexible circuit board through the ventilation plate.

[0037] When the flexible circuit board moves to the right along the conveyor belt 31, the flexible circuit board will enter the interior of the storage box 43 through the feed port 45 along the inclined plate installed on the connecting inclined plate 41, and the flexible circuit board entering the bellows 42 will be cooled by the cold air component 44. When the storage box 43 is full of flexible circuit boards, the storage box 43 can be pulled out from the inner cavity of the bellows 42, and then the pressurized and cooled flexible circuit board can be taken out.

[0038] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
