[0044] like Figure 7 and Figure 8 The material guiding device 6 comprises a transmission turntable 65, the upper end surface of the transmission turntable 65 is provided with eight groups of fixed slots 66 at equal intervals, and a material unloading guide slot 64 is provided at the center of the inner end surface of the fixed slot 66, the inner end surface of the fixed slot 66 is elastically slidably connected with a positioning fixture 67, and a spring clamping shaft 68 is symmetrically provided on the lower end surface of the positioning fixture 67, a groove wheel rotating plate 62 is fixedly provided at the center of the upper end surface of the transmission turntable 65, and eight groups of limiting circular grooves 63 are provided at equal intervals on the side end surface of the groove wheel rotating plate 62, and a guide slide slot 61 is provided between two adjacent groups of limiting circular grooves 63.

[0045] The first synchronous pulley 21 is meshed and connected with the second synchronous pulley 48 through the synchronous belt 1. The unloading guide groove 64 is coaxial with the unloading cylinder 7, which can improve the accuracy of subsequent unloading. When the keycap loading plate 51 is extended to the limit, it is directly opposite to the bottom of the keycap adsorption fixture 43. When loading multiple groups of keycaps, the external feeding module can position the keycaps equidistantly inside the keycap loading plate 51, and then the rodless cylinder 53 can guide the keycap loading plate 51 to the bottom of the keycap adsorption fixture 43. The external vacuum generator can generate negative pressure inside the keycap adsorption fixture 43 through the sealing card plate 44, thereby completing the adsorption of the keycaps.

[0046] The fixed clamping ring 42 is adapted to the circulation slide groove 47 through the limit clamping shaft 46 and then slidably clamped on the outer end surface of the transmission guide roller 41, and the four groups of guide slide shafts 45 are all slidably clamped with the inside of the support top plate 3. The circulation slide groove 47 is arranged in a circulation shape. The rotating transmission guide roller 41 can drive the fixed clamping ring 42 to move up and down in a cycle through the cooperation of the circulation slide groove 47 and the limit clamping shaft 46, which can facilitate the subsequent intermittent loading of the transmission turntable 65, so that the keycap adsorption fixture 43 can perform cyclic processing on the keyboard workpiece.

[0047] The internal shape of the unloading bin 12 is the same as the opening shape of the alignment fixture 67, and the bottom of the unloading bin 12 is flush with the upper end surface of the alignment fixture 67. The alignment fixture 67 is elastically slidably connected to the inner end surface of the fixed slot 66 through the spring clamping shaft 68. When unloading the keyboard workpiece, the opening at the bottom of the unloading bin 12 can be directly opposite to the alignment fixture 67. At the same time, when the first group of unloading is completed, the lowermost keyboard workpiece and the upper surface of the transmission turntable 65 can limit the remaining workpieces inside the unloading bin 12, thereby improving the stability of subsequent unloading one by one. The spring clamping shaft 68 is fixedly set on the lower end surface of the transmission turntable 65. After the unloading cylinder 7 drives the alignment fixture 67 to complete the lifting and unloading, the two groups of spring clamping shafts 68 can use elastic force to make the alignment fixture 67 firmly fit the bottom wall of the fixed slot 66, thereby improving the stability of the subsequent keycap adsorption fixture 43 pressing the keyboard workpiece inside the alignment fixture 67.

[0048] The guide swing arm 24 is adapted to the guide slide groove 61 through the connecting swing rod 25, thereby driving the transmission turntable 65 to rotate intermittently, and the notched disc 23 is slidably engaged with the groove wheel rotating plate 62 through the limiting circular groove 63. The connecting swing rod 25 can be limited by the sliding with the guide slide groove 61, and then cyclically and intermittently drive the transmission turntable 65 to rotate, so that the transmission turntable 65 can cyclically drive the keyboard workpiece inside the positioning fixture 67 to cyclically load the keyboard workpiece, effectively improving the loading stability and efficiency. When the connecting swing rod 25 rotates one circle, the front part has the connecting swing rod 25 and the guide slide groove 61 for toggle connection, and the rear part is limited by the notched disc 23 and the limiting circular groove 63, which can facilitate the subsequent maintenance of the stability of the transmission turntable 65 and improve the stability of the subsequent pressing.

[0049] Working principle: Before use, the staff can position the keycap feeding module to the upper part of the feeding device 5 to facilitate the subsequent continuous supply of keycaps to the inside of the pressing device 4, and the unloading robot can be positioned to the rear of the unloading cylinder 7, and then the loading robot can be positioned to the front station of the unloading cylinder 7 to facilitate the loading operation. When the keycaps are pressed on the keyboard, the loading robot can position the keyboard workpiece to the inside of the positioning fixture 67, and then the keycap feeding module can position the batch pressed keycaps to the inside of the keycap loading plate 51. When the keycaps are pressed, the servo motor 10 is started, and the servo motor 10 can drive the L-type reducer 9 to rotate, and at the same time, the L-type reducer 9 can drive the transmission card shaft 22 to rotate, and the transmission card shaft 22 The notched disc 23, the guide swing arm 24 and the first synchronous pulley 21 can be synchronously driven to rotate synchronously. When the guide swing arm 24 rotates, the guide swing arm 24 can be limited by the sliding connection between the swing rod 25 and the guide slide groove 61, so that when the guide swing arm 24 rotates one circle, it can drive the groove wheel rotating plate 62 to rotate one eighth of a circle. At the same time, when the guide swing arm 24 is separated from the guide slide groove 61, the notched disc 23 can be limited by the sliding connection with the limiting circular groove 63, thereby limiting and locking the groove wheel rotating plate 62, so that when the transmission card shaft 22 is transmitting, it can cyclically drive the transmission turntable 65 to rotate intermittently. When the above-mentioned transmission card shaft 22 is transmitting, the transmission card shaft 22 can be connected to the first synchronous pulley 21 and the synchronous belt 1 and the second synchronous pulley 48 synchronously drive the transmission guide roller 41 to rotate, and the transmission guide roller 41 can drive the circulation slide 47 to circulate and rotate. In the initial state, the fixed clamp ring 42 is located at the top of the transmission guide roller 41, and at the same time, the rodless cylinder 53 can drive the keycap feeding plate 51 and the keycaps inside it to be positioned to the bottom of the keycap adsorption fixture 43 through the connection seat 52. At this time, the keycap adsorption fixture 43 can adsorb multiple groups of keycaps, and then the connecting swing rod 25 just toggles the groove rotating plate 62 to rotate eight minutes of a circle, and at the same time, the station of a new group of fixed clamping grooves 66 is moved to the bottom of the keycap adsorption fixture 43. At this time, the circulation slide 47 can drive the fixed clamp ring 42 to move downward synchronously through the limit clamping shaft 46, and at this time, the notched disc 23 begins to contact the limit The circular groove 63 is limited to maintain the stability of the groove wheel plate 62 and the transmission turntable 65 until the keycap adsorption jig 43 is completely pressed on the keyboard workpiece inside the alignment jig 67, thereby completing the keycap pressing operation, and then the keycap adsorption jig 43 begins to reset, and at the same time the notched disc 23 is separated from the limiting circular groove 63, completing the pressing operation, as the connecting rocker 25 continues to be moved with the guide slide groove 61, the keyboard workpiece that has been pressed is driven by the transmission turntable 65 to rotate to the bottom of the unloading cylinder 7, and then the unloading cylinder 7 can drive the alignment jig 67 to lift up, and the external unloading manipulator can take out the keyboard workpiece with the keycap pressed, and then the alignment jig 67 is reset under the elastic contraction of the spring clamp shaft 68 to complete the processing operation.
