[0037] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0038] Reference Figures 1 to 9 As shown, the automatic loading and clamping machine 100 according to the embodiment of the present invention includes: a fixture feeding mechanism 120, a conveying mechanism 130 and a product transfer mechanism 140; the fixture feeding mechanism 120 includes a feeding shaft 211 and a fixture connecting plate 212, the fixture connecting plate 212 is slidably connected to the feeding shaft 211, and the fixture connecting plate 212 is used to install a first fixture 213 for mounting multiple products; the conveying mechanism 130 includes a product conveying device 131, a clamping device 132 and a cover closing device 133, and a plurality of second fixtures 134 are arranged on the product conveying device 131, and the product conveying device 131 is used to convey the second fixture 134, and the second fixture 134 is used to convey the second fixture 134. The fixture 134 is provided with a positioning clamp 310 and a pressure cover 320; the clamp opening device 132 includes a first extending mechanism 720 and a push block 730, the push block 730 is arranged on the first extending mechanism 720, and the first extending mechanism 720 is used to extend and drive the push block 730 to push and open the positioning clamp 310; the cover closing device 133 includes a second extending mechanism 820 and a push claw 830, the push claw 830 is arranged on the second extending mechanism 820, and the second extending mechanism 820 is used to extend and drive the push claw 830 to push and close the pressure cover 320; the product transfer mechanism 140 is used to grab the product from the first fixture 213 and place it on the second fixture 134.

[0039] The automatic loading and clamping machine 100 according to the embodiment of the present invention has at least the following beneficial effects: after the first fixture 213 for mounting multiple products is installed on the fixture connecting plate 212, it slides along the loading shaft 211 to the material picking position of the product transfer mechanism 140; a plurality of second fixtures 134 are arranged on the conveying device, and the product conveying device 131 is used to convey the second fixture 134. When the second fixture 134 is conveyed to the loading position of the product transfer mechanism 140, the clamping device 132 of the conveying mechanism 130 will extend through the first extending mechanism 720 and drive the push block 730 to push and press to open the positioning clamp 310 on the second fixture 134. At this time, the product transfer mechanism 140 will produce The product is loaded onto the second fixture 134, the clamping device 132 stops pressing so that the positioning clamp 310 of the second fixture 134 clamps the product, and the cover closing device 133 extends through the second extending mechanism 820 and drives the pusher claw 830 to push the pressure cover 320 located above the positioning clamp 310 to close it and press down the product, thereby completing the clamping of the product, and then the product conveying device 131 removes the second fixture 134 and performs the product clamping operation on the next second fixture 134; the above work processes are all performed by machinery instead of manual work, which can greatly improve the transfer and clamping efficiency of products on different fixtures, and can also avoid damage to the product during the clamping process due to manual accidents.

[0040] It is understandable that, referring to Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the automatic loading and clamping machine 100 may also include a frame 110, and the fixture feeding mechanism 120, the conveying mechanism 130 and the product transfer mechanism 140 are all arranged on the upper surface of the frame 110. The frame 110 can adjust the height of different positions on the upper surface according to the working height of each mechanism. Further, a stepped structure can be used on the frame 110 to reduce the height of the product transfer mechanism 140 relative to other parts, so that the working height of each mechanism when the product is transferred from the first fixture 213 to the second fixture 134 remains the same, so that the coordinated work of each mechanism is smoother. The stepped position of the upper surface of the frame 110 where the product transfer mechanism 140 is located can also be further lowered, and devices for other functions can be added therein, such as a circulation channel of the second fixture 134 connected to other process equipment or a recovery channel of the second fixture 134 carrying the product, etc., so as to facilitate the function expansion of the automatic loading and clamping machine 100, and can also be used to cooperate with other equipment to form an assembly line for products such as wireless headset charging shells, further improving production efficiency.

[0041] In some specific embodiments of the present invention, referring to Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the product conveying device 131 includes a first conveyor belt 220, a second conveyor belt 610 and a jig reflux device 240, the clamping device 132 is arranged on the first conveyor belt 220, the cover closing device 133 is arranged on one side of the first conveyor belt 220, the second conveyor belt 610 is arranged below the first conveyor belt 220, the second conveyor belt 610 is used to convey the second jig 134 without product, and the jig reflux device 240 is used to receive the second jig 134 from the second conveyor belt 610 and transport the second jig 134 to the first conveyor belt 220. Specifically, the working process of the product conveying device 131 includes: a plurality of second jigs 134 opened by the pressure caps 320 are input into the second conveyor belt 610 through other equipment or manually, and the second conveyor belt 610 conveys the second jigs 134 to the jig return device 240. When the jig return device 240 senses the input of the second jig 134, it lifts the second jig 134 to the height of the first conveyor belt 220 and inputs the second jig 134 into the first conveyor belt 220. The first conveyor belt 220 then removes the jigs 134 from the first conveyor belt 220. The second jig 134 input by the reflux device 240 is transferred to the loading position of the product transfer mechanism 140, and the clamping device 132 arranged on the first conveyor belt 220 presses and opens the positioning clamp 310 of the second jig 134. When the product is clamped on the second jig 134, the clamping device 132 stops pressing, the positioning clamp 310 clamps the product, and the cover closing device 133 arranged on one side of the first conveyor belt 220 moves to close the cover 320, and then the second jig 134 loaded with the product is removed by the first conveyor belt 220. It can be understood that the jig reflux device 240 can receive multiple second jigs 134 from the second conveyor belt 610 at one time, and lift and transport them to the first conveyor belt 220. The second conveyor belt 610 can also be provided with a stop structure or stop working during the lifting process of the jig reflux device 240 to prevent the second jig 134 on the second conveyor belt 610 from excessively moving out of the second conveyor belt 610.

[0042] It is understandable that, referring to Figure 5 , Figure 6As shown, the jig reflow device 240 also includes a third conveyor belt 510 and a lifting mechanism 520. The third conveyor belt 510 is also provided with a first sensor 511, a second sensor 512, a third sensor 513 and a first waiting position 514. The first sensor 511 is used to sense that the second jig 134 is conveyed into the third conveyor belt 510, the second sensor 512 is used to sense that the second jig 134 arrives at the first waiting position 514, the third sensor 513 is used to sense that the second jig 134 moves out of the third conveyor belt 510, and the lifting mechanism 520 is used to lift the third conveyor belt 510 to the height of the first conveyor belt 220 or lower the third conveyor belt 510 to the height of the second conveyor belt 610. The working process of the fixture reflow device 240 may include: a plurality of second fixtures 134 are conveyed from the second conveyor belt 610 to the third conveyor belt 510; the first sensor 511 senses that the last second fixture 134 that can be accommodated by the third conveyor belt 510 is completely conveyed to the third conveyor belt 510, and the lifting mechanism 520 lifts the third conveyor belt 510; when the second sensor 512 senses that the second fixture 134 has arrived at the first waiting position 514, the third conveyor belt 510 stops running; the lifting mechanism 520 lifts the third conveyor belt 510 to the first waiting position 514. When the first conveyor belt 220 is at a certain height, the third conveyor belt 510 transfers the second fixture 134 to the first conveyor belt 220 by changing the conveying direction to face the first conveyor belt 220; when the third sensor 513 senses that the last second fixture 134 on the third conveyor belt 510 is also transferred to the first conveyor belt 220, the lifting mechanism 520 lowers the third conveyor belt 510 to the height of the second conveyor belt 610, and the rotation direction of the third conveyor belt 510 is changed to transfer the second fixture 134 from the second conveyor belt 610 to the third conveyor belt 510.

[0043] It should be noted that the number of second jigs 134 that can be accommodated on the third conveyor belt 510 is set corresponding to the judgment condition of the relevant sensor. For example, when the third conveyor belt 510 can accommodate two second jigs 134, the corresponding control module has a longer judgment time for the sensing signal of the relevant sensor than when the third conveyor belt 510 only accommodates one second jig 134. The setting is specifically made according to the working speed of the product conveying device 131. The first waiting position 514 is set at the far end of the third conveyor belt 510 relative to the first conveyor belt 220 and the second conveyor belt 610. The functions of the first sensor 511 and the third sensor 513 can also be implemented by one sensor. The specific implementation process can be to sense the inflow of the second jig 134 when the third conveyor belt 510 is at the height of the second conveyor belt 610, and to sense the outflow of the second jig 134 when the third conveyor belt 510 is at the height of the first conveyor belt 220. Multiple second sensors 512 can be set up on both sides and the bottom of one end of the third conveyor belt 510. When all the second sensors 512 send out sensing signals, the third conveyor belt 510 will stop, thereby avoiding false triggering caused by accidents. The function of the second sensor 512 can also be achieved by the corresponding control module controlling the moment when the third conveyor belt 510 stops through timing after the first sensor 511 sends out a sensing signal. The use of multiple sensors for sensing is conducive to improving work accuracy, avoiding accidents, and thus improving overall work efficiency. The combination of the second conveyor belt 610 and the fixture reflow device 240 can reduce the space occupied by the first conveyor belt 220 while stably supplying the second fixture 134, thereby maintaining the work efficiency of the clamping process.

[0044] It is understandable that, referring to Figure 6As shown, the second conveyor belt 610 is provided with a first blocking device 611, a second blocking device 612, a fourth sensor 613, a fifth sensor 614, a sixth sensor 615 and a second waiting position 616, the first blocking device 611 is used to block the second fixture 134 so that it stops at the second waiting position 616, the fourth sensor 613 is used to sense that the second fixture 134 is in the second waiting position 616, the fifth sensor 614 is used to sense that the second fixture 134 moves out of the second waiting position 616, the second blocking device 612 is used to prevent multiple second fixtures 134 from entering the second waiting position 616, and the sixth sensor 615 is used to sense the carrying state of the second conveyor belt 610. The working process of the second conveyor belt 610 may include: a plurality of second jigs 134 are input into the second conveyor belt 610, and the first blocking device 611 blocks the second jigs 134 and stops them at the second waiting position 616; when the fourth sensor 613 senses that the last second jig 134 that can be accommodated in the second waiting position 616 is transmitted into and stops in the second waiting position 616, the second blocking device 612 is lifted and used to block other second jigs 134 from entering the second waiting position 616; when the third conveyor belt 510 is lowered to the height of the second conveyor belt 610, the first blocking device 611 The second jig 134 in the second waiting device is transferred to the third conveyor belt 510; the fifth sensor 614 senses that the second jig 134 is transferred out of the second waiting position 616, the first blocking device 611 is retracted, the second blocking device 612 is extended, and the subsequent second jig 134 enters the second waiting position 616; when the sixth sensor 615 senses that the second jig 134 of the second conveyor belt 610 is blocked and stops at the input port of the second conveyor belt 610, and the third conveyor belt 510 has not yet dropped to the height of the second conveyor belt 610, the second conveyor belt 610 stops transporting. The above process can control the number of second jigs 134 flowing into the second conveyor belt 610 to avoid overcrowding of the second conveyor belt 610; the second waiting position 616 can be set at one end of the second conveyor belt 610 close to the jig return device 240; the second waiting position 616 is used to pre-store the second jig 134 to be sent to the third conveyor belt 510.

[0045] It should be noted that when the capacity of the second fixture 134 of the second waiting position 616 is the same as that of the second fixture 134 of the third conveyor belt 510, it is beneficial to simplify the management and control process of the coordinated work, thereby improving work efficiency. When the second waiting position 616 can accommodate multiple second fixtures 134, and the number of second fixtures 134 that the third conveyor belt 510 can accommodate is the same as that of the second waiting position 616, the second fixtures 134 that can accommodate the largest number are grouped as a group, and the working process of the second conveyor belt 610 can also include: when the fifth sensor 614 senses that the first of a group of second fixtures 134 in the second waiting position 616 moves out of the second waiting position 616, the second blocking device 612 retracts so that the next group of second fixtures 134 flows into the second waiting position 616; when the fifth sensor 614 senses that the previous group of second fixtures 134 have all moved out of the second waiting position 616, the first blocking device 611 extends; when the fourth sensor 613 senses that the next group of second fixtures 134 have all entered the second waiting position 616, the second blocking device 612 extends. The above process coordinates the working process of multiple groups of second fixtures 134 when they are on the second conveyor belt 610, thereby improving the conveying efficiency, avoiding frequent overfilling and suspension of the second conveyor belt 610, and improving the working efficiency.

[0046] It can be understood that the first conveyor belt 220 is provided with a third blocking device 621, a fourth blocking device 622, a first lifting cylinder 623, a fixed plate 624, a seventh sensor 625, an eighth sensor 626 and a jig loading position 221, the fixed plate 624 is fixedly arranged at the jig loading position 221, the seventh sensor 625 is used to sense that the second jig 134 is at the jig loading position 221, the third blocking device 621 is used to block the second jig 134 to stop it at the jig loading position 221, the first lifting cylinder 623 is used to cooperate with the fixed plate 624 to lift and position the second jig 134 at the jig loading position 221, the fourth blocking device 622 is used to prevent multiple second jigs 134 from entering the jig loading position 221, and the eighth sensor 626 is used to sense that the second jig 134 moves out of the jig loading position 221. The working process of the first conveyor belt 220 may include: the first conveyor belt 220 receives the second jig 134 transmitted from the third conveyor belt 510; the third blocking device 621 blocks the second jig 134 and stops it on the jig loading device; the seventh sensor 625 senses the second jig 134 blocked by the third blocking device 621, the fourth blocking device 622 extends and blocks the subsequent second jig 134, and the first lifting cylinder 623 lifts the second jig 134 at the jig loading position 221 until the second jig 134 is close to the fixed plate 624; the loading process is completed, the first lifting cylinder 623 descends, the third blocking device 621 retracts, and the second jig 134 moves out of the jig loading device; the eighth sensor 626 senses that the second jig 134 moves out of the jig loading device, the third blocking device 621 extends, the fourth blocking device 622 retracts, and the next second jig 134 is conveyed into the jig loading device. The fixture loading position 221 uses the first lifting cylinder 623 to perform secondary positioning on the second fixture 134 and cooperates with the fixing plate 624 to clamp the second fixture 134, which is beneficial to the stability of the opening of the positioning clamp 310 and the loading process.

[0047] It is understandable that the first blocking device 611, the second blocking device 612, and the third blocking device 621 can be composed of a blocking structure with a cylinder and a telescopic end of the cylinder fixed, the cylinder part is installed at the bottom or both sides of the corresponding conveyor belt, and the telescopic end is used to stop the second fixture 134. The cylinder part can also be replaced by a stepper motor, and the use of a cylinder can reduce costs.

[0048] It is understandable that, referring to Figure 1 and Figure 7As shown, the clamping device 132 includes a first bracket 710; the first extension mechanism 720 includes a longitudinal cylinder 721 and a first transverse cylinder 722. The first bracket 710 is fixed to the jig loading position 221, the longitudinal cylinder 721 is fixed to the first bracket 710, the first transverse cylinder 722 is fixed to the telescopic end of the longitudinal cylinder 721, and the push block 730 is arranged at the telescopic end of the first transverse cylinder 722. The push block 730 is used to push and open the positioning clamp 310. The working process of the clamping device 132 includes: the longitudinal cylinder 721 pushes the first transverse cylinder 722 to the same height as the second jig 134 fixed to the jig loading position 221; the first transverse cylinder 722 pushes the push block 730 and then pushes the positioning clamp 310, so that the positioning clamp 310 is opened; after the second jig 134 is loaded with the product, the first transverse cylinder 722 retracts the push block 730, and the longitudinal cylinder 721 retracts the first transverse cylinder 722. The cylinder of the clamping device 132 can also be replaced by a stepper motor, and the use of a cylinder is convenient for reducing costs and simplifying control steps.

[0049] According to some embodiments of the present invention, referring to Figure 1 and Figure 8 As shown, the cover closing device 133 also includes a second bracket 810, and the second extension mechanism 820 includes a second horizontal cylinder 821 and a rotating cylinder 822. The second horizontal cylinder 821 is fixed on the top of the second bracket 810, and the rotating cylinder 822 is arranged at the telescopic end of the second horizontal cylinder 821. The pusher claw 830 is arranged at the rotating end of the rotating cylinder 822. The working steps of the cover opening device may include: the second fixture 134 with the product clamped is fixed at the fixture feeding position 221, the second horizontal cylinder 821 extends out of the rotating cylinder 822, the rotating cylinder 822 rotates the pusher claw 830, and the pusher claw 830 pushes the cover 320 to close it. The cylinder of the clamping device 132 can be replaced with a motor, and the use of the cylinder is convenient for simplifying the control process and saving costs.

[0050] It is understandable that, referring to Figure 3As shown, the second fixture 134 also includes a fixture substrate 330 and a fixture base 340. The fixture base 340 is fixed on the fixture substrate 330. The positioning clamp 310 is a spring clamp, which is movably connected to the fixture base 340. The pressure cover 320 is rotatably connected to the fixture base 330 and is arranged above the spring clamp. The push block 730 pushes the spring clamp to slide relative to the fixture base 330 to open the clamping opening. The positioning clamp 310 of the second fixture 134 is a spring clamp. Pushing the positioning clamp 310 forward from the rear can make the clamp body of the positioning clamp 310 slide forward relatively, that is, open the clamping opening of the positioning clamp 310. At this time, the product can be placed in the clamping opening, stop pushing the positioning clamp 310 and retract the structure used for pushing, and the positioning clamp 310 is reset and clamps the product. The pressure cover 320 is rotatably connected to the second fixture 134. The cover 320 is pre-opened before the second jig 134 is input into the product conveying device 131, or a cover-opening structure is provided in front of the jig loading position 221 of the conveying mechanism 130 to open the cover. A magnetic structure can be provided at the front end of the cover 320, and a magnetic structure is also provided at the corresponding clamping position of the second jig 134, so that the cover 320 can more tightly press the product when closing the cover.

[0051] It is understandable that, referring to Figure 1 , Figure 2 , Figure 6 and Fig. 9 As shown, the product transfer mechanism 140 includes a third bracket 910, a Y-axis moving module 232, an X-axis moving module 231 and a transfer clamp 233. The third bracket 910 is set above the fixture feeding mechanism 120 and the conveying mechanism 130, the Y-axis moving module 232 is fixedly set on the third bracket 910, the X-axis moving module 231 is slidably connected to the Y-axis moving module 232, and the transfer clamp 233 is slidably connected to the X-axis moving module 231. The product transfer mechanism 140 is connected to the frame 110 through the third bracket 910 and is assumed to be above the fixture feeding mechanism 120 and the conveying mechanism 130, which is beneficial to flexibly grasp the product and transfer it to the second fixture 134 at the fixture loading position 221, avoiding accidents and interferences caused by mutual contact when different mechanisms are working, and improving work efficiency.
