The invention includes an operating platform, a lower mold, an L-shaped connecting plate, a hydraulic cylinder 2, a control panel, a screw 2 and an upper mold. A card slot 1 is provided on the inner side walls on both sides of the operating platform. A fixed plate 1 is slidably connected to the inner surface of the operating platform card slot 1. An L-shaped connecting plate 2 is welded to the upper surface of the fixed plate 1. Card slots are provided on the inner side walls on both sides of the lower mold.

The two sets of fixed guide rods 65 are slidably engaged with the support base 62. The threaded connection between the threaded sleeve 69 and the ball screw 64 can effectively improve the accuracy of the material guide push plate 68 in pushing the circuit board pressing fixture 5 to move inside the upper bin 61 and the material guide chute 7.

[0067] like Figure 6 and Figure 8 The pressing slide 34 is slidably connected to the inner end surface of the limit support 44 through the support slide shaft 45, and the pressing slide 34 is elastically fitted with the buffer clamp ring 2 when it moves to the bottom. The support slide shaft 45 can provide a sufficient guiding basis for the pressing slide 34, thereby improving the stability of the displacement of the pressing slide 34 inside the limit support 44. The buffer clamp ring 2 can limit and protect the bottom of the pressing slide 34.

[0068] like Figure 4 and Figure 6 The bottom of the positioning clamp 33 is provided with a rounded corner for positioning, and the positioning clamp 33 is connected with the side of the circuit board pressing jig 5 through the rounded corner. When the pressing slide 34 moves down, the positioning rounded corner at the bottom of the positioning clamp 33 can first contact the side of the circuit board pressing jig 5. The arc surface setting of the rounded corner can make the circuit board pressing jig 5 quickly centered, thereby improving the stability of the subsequent pressing slide 34 limiting the circuit board pressing jig 5.

[0069] The pressing slide 34 is adapted to the positioning guide groove 8 through the positioning clamp plate 33 and then slidably inserted into the inner end surface of the supporting slide 1. The positioning guide groove 8 can provide sufficient guiding basis for the positioning clamp plate 33, thereby improving the stability of the subsequent limiting of the circuit board pressing fixture 5 by the positioning clamp plate 33.

[0070] like Figure 5 and Fig.13 The alignment slide 417 is adapted to the guide slide shaft 311 through the guide rail 412, thereby driving the pressing guide plate 312 to flip around the transmission card shaft 314 as the axis. The fixed crankshaft 313 is hinged to the limit rotating seat 35 through the fixed rotating plate 36. The guide rail 412 has a sufficient length to provide sufficient longitudinal displacement space for the guide slide shaft 311 to flip up and down. At the same time, when the guide rail 412 moves forward and backward, it can drive the pressing guide plate 312 to flip around the transmission card shaft 314 as the axis, which is convenient for the subsequent fixed crankshaft 313 to drive the limit rotating seat 35 to move up and down through the fixed rotating plate 36 to perform cyclic pressing on the circuit board pressing fixture 5.

[0071] like Fig.12 The alignment slide 417 is adapted to the cam slide groove 49 through the limiting slide shaft 416 and then slidably connected to the inside of the support guide seat 48. The servo motor 42 can drive the transmission roller 47 to rotate in one direction through the L-type reducer 43. The transmission roller 47 can be limited by the sliding of the cam slide groove 49 and the limiting slide shaft 416, and cyclically drive the pushing device 41 to move forward and backward, which is convenient for the subsequent feeding and pressing of the circuit board pressing fixture 5. Provide circulating power.

[0072] like Fig. 9 and Fig.13 The support bracket 415 is slidably connected to the front of the limit support 44 through the fixed slide 46. The fixed slide 46 can provide sufficient guiding space for the support bracket 415, which can improve the distance between the bottom of the support bracket 415 and the support slide 1 to remain unchanged, and improve the stability of the material guide of the circuit board pressing fixture 5.

[0073] like Fig.13 The length of the loading pressing plate 414 is greater than the length of the loading pushing plate 413, so that the subsequent loading pressing plate 414 can limit the pushing end of the circuit board pressing fixture 5 and facilitate the subsequent circuit board pressing fixture 5 to tilt when guiding the material.

[0074] In addition, a guide chamfer is provided at the corner of the lower end surface of the loading pressure plate 414, and the front part of the loading push plate 413 and the lower part of the loading pressure plate 414 are both fitted and connected to the outside of the circuit board pressing jig 5, which can effectively improve the stability of the subsequent loading push plate 413 and the loading pressure plate 414 in guiding the circuit board pressing jig 5.

[0075] Working principle: Figure 1 and Fig.15 Before use, if feeding operation is required, the staff can sequentially introduce the circuit board pressing jig 5 with the circuit board to be pressed inside to the upper part of the material guide push plate 68, and then start the stepper motor 66. At this time, the stepper motor 66 can drive the active gear 67 to rotate, and the active gear 67 can be connected with the driven gear 63 through meshing, thereby driving the threaded sleeve 69 to rotate, and the threaded sleeve 69 can be connected with the ball screw 64 through the thread, thereby driving the ball screw 64 and the material guide push plate 68 to be stably lifted inside the upper bin 61, until the uppermost group of circuit board pressing jigs 5 are parallel to the upper surface of the support slide 1, thereby completing the feeding operation of the circuit board;

[0076] like Figure 1 , Figure 5 and Figure 8 When performing transmission operation, the staff can start the servo motor 42, and the servo motor 42 can drive the L-shaped reducer 43 at the bottom to rotate, and the L-shaped reducer 43 can drive the transmission roller 47 at the side to rotate. When the transmission roller 47 rotates, the transmission roller 47 can drive the pusher 41 to move forward and backward in a cycle inside the support guide seat 48 through the cam slide 49;

[0077] like Figure 6 , Figure 7 , Fig. 9 and Fig.13 As shown, in the initial state, as mentioned above Fig. 9 As shown, at this time, the loading pressing plate 414 and the loading pushing plate 413 are located in front of the latest set of circuit board pressing fixtures 5, and the pressing slide 34 is located at the end position of pressing. When the pushing device 41 is displaced under the drive of the cam slide 49, as shown in FIG. Figure 8 First, the driving roller 47 can be limited by the sliding of the cam slide 49 and the limiting slide shaft 416, thereby driving the alignment slide 417 to move forward. At this time, the alignment slide 417 can synchronously drive the support bracket 415 and the support guide shaft 418 to move forward. Figure 2 and Figure 5The supporting guide shaft 418 can be limited by the sliding of the guide rail 412 and the guide slide shaft 311, thereby driving the two sets of pressing guide plates 312 to rotate with the transmission card shaft 314 as the axis. At this time, the guide slide shaft 311 located at the upper part begins to flip toward the bottom, and at the same time, the fixed crankshaft 313 begins to flip and move upward along the limit card seat 315 as the axis. When the fixed crankshaft 313 flips, the fixed crankshaft 313 can be connected with the fixed rotating plate 36 through rotation, thereby driving the two sets of limit rotating seats 35 and the pressing slide seat 34 to be lifted synchronously. Figure 2 and Figure 3 When the pressing slide 34 is lifted, the supporting bracket 415 and the guide rail 412 move forward synchronously, so the loading push plate 413 can push the side of a new set of circuit board pressing jigs 5 for loading, and the loading pressure plate 414 can limit the upper part of the circuit board pressing jig 5 to improve the stability of the pushing. When the limiting slide shaft 416 is driven by the cam slide groove 49 to move to the front limit, the pressing slide 34 is lifted to the limit by the fixed rotating plate 36, and the circuit board pressing jig 5 is pushed to the bottom of the pressing slide 34 by the loading push plate 413 and the loading pressure plate 414, and the loading is completed synchronously.

[0078] like Figure 2 , Figure 4 and Figure 6 When the above-mentioned circuit board pressing jig 5 is loaded, as the driving roller 47 continues to rotate, the cam slide 49 can drive the alignment slide 417 to start the reset movement through the limiting slide shaft 416, so that the alignment slide 417, the loading push plate 413, and the guide slide rail 412 start to move toward the rear. At this time, the loading push plate 413 and the loading pressure plate 414 can be separated from the circuit board pressing jig 5, thereby providing sufficient space for the subsequent pressing slide 34 and the circuit board pressing mold 37 to press the circuit board pressing jig 5. Subsequently, the guide slide rail 412 can drive the pressing guide plate 312 and the fixed crankshaft 313 to move downward from the top with the driving card shaft 314 as the axis through the sliding limit with the guide slide shaft 311. At the same time, when the fixed crankshaft 313 is flipped and moved downward, it can drive the pressing slide 34 and the circuit board pressing mold 37 to move downward synchronously through the fixed rotating plate 36, such as Figure 3 , Figure 4 and Figure 6When the pressing slide 34 and the circuit board pressing mold 37 are close to the circuit board pressing jig 5, the eight groups of positioning clamps 33 can first be aligned to the alignment grooves outside the circuit board pressing jig 5, so that the multiple groups of positioning clamps 33 can automatically align and center the circuit board pressing jig 5 during the downward movement. After the centering is completed, the pressing slide 34 can drive the circuit board pressing mold 37 to press the circuit board inside the circuit board pressing jig 5. When the pressing is completed, the loading device 6 can guide a new group of circuit board pressing jigs 5 to the upper surface of the buffer clamp 2. When the pressing slide 34 and the circuit board pressing mold 37 are lifted again, the loading push plate 413 can then automatically eject the pressed circuit board pressing jig 5 and the circuit board through a new group of circuit board pressing jigs 5.
