[0022] Some embodiments of the present application will be described in detail with reference to the drawings.

[0023] Referring to Figure 1 The tray feeding device 100 provided by the embodiments of the present application is used for feeding a tray 300. The tray 300 can be used to carry parts of electronic products such as mobile phones and tablet computers.

[0024] Referring to Figure 1 and Figure 2 In the embodiments, the tray feeding device 100 comprises a conveying and positioning mechanism 10 and a transfer mechanism 20.

[0025] The conveying and positioning mechanism 10 comprises a conveying assembly 11, a first positioning member 12 and a second positioning member 13. The first positioning member 12 and the second positioning member 13 are respectively slidably connected to opposite sides of the conveying assembly 11. The distance between the first positioning member 12 and the second positioning member 13 is adjustable, and the first positioning member 12 and the second positioning member 13 are used to adjustably abut and position trays 300 of different specifications from both sides, so as to position trays 300 of different sizes. The conveying assembly 11 has a feeding position 1111, which is located between the first positioning member 12 and the second positioning member 13. The conveying assembly 11 is used to carry the tray 300 and move the tray 300 to the feeding position 1111.

[0026] The transfer mechanism 20 is arranged on one side of the conveying assembly 11, and is used to grab the positioned tray 300 from the conveying assembly 11 for feeding.

[0027] Specifically, when the tray feeding device 100 feeds the tray 300, the conveying assembly 11 moves the tray 300 to the feeding position 1111 and between the first positioning member 12 and the second positioning member 13. The first positioning member 12 and the second positioning member 13 slightly contact the tray 300 from both sides to position the tray 300. The transfer mechanism 20 grabs the tray 300 from the feeding position 1111 for feeding. Since the entire process of feeding the tray 300 is in an automatic manner, the efficiency of feeding the tray 300 is improved. When the size of the tray 300 changes, only the first positioning member 12 and the second positioning member 13 need to be moved and the distance between the first positioning member 12 and the second positioning member 13 needs to be adjusted correspondingly. Then the first positioning member 12 and the second positioning member 13 can reposition the tray 300. The process of adjusting the tray feeding device 100 is simple and short in time, thereby improving the versatility of the tray feeding device 100 for feeding the tray 300 and further improving the efficiency of feeding the tray 300.

The support frame 111 extends along the X-axis direction, a feeding position 1111 is arranged on the support frame 111, and the first positioning member 12 and the second positioning member 13 are slidingly connected to opposite sides of the support frame 111. The first transmission roller 112 is rotatably arranged at one end of the support frame 111, and the second transmission roller 113 is rotatably arranged at the other end of the support frame 111. The conveying belt 114 is sleeved on the first transmission roller 112 and the second transmission roller 113, and is used for carrying the tray 300. The rotating driving member 115 is arranged on the support frame 111 and connected with the first transmission roller 112 or the second transmission roller 113, and is used for driving the first transmission roller 112 and the second transmission roller 113 to rotate, so that the conveying belt 114 drives the tray 300 to move. The rotating driving member 115 can be a servo motor. In this way, the conveying assembly 11 has a simple structure and is conducive to improving the accuracy of driving the tray 300 to move.

[0029] In the embodiment, the positions where the conveying assembly 11 is connected with the first positioning member 12 and the second positioning member 13 are respectively provided with a first waist-shaped hole 1112 and a second waist-shaped hole 1113, the first positioning member 12 and the second positioning member 13 are respectively provided with a first connecting hole 1201 and a second connecting hole 1301, the extension directions of the first waist-shaped hole 1112 and the second waist-shaped hole 1113 are the sliding directions of the first positioning member 12 and the second positioning member 13, and the first positioning member 12 and the second positioning member 13 slide along the Y-axis direction. The conveying and positioning mechanism 10 further comprises a first connecting member 14 and a second connecting member 15. The first connecting member 14 penetrates through the first waist-shaped hole 1112 and is connected with the first connecting hole 1201, and the second connecting member 15 penetrates through the second waist-shaped hole 1113 and is connected with the second connecting hole 1301, so as to slidingly connect the first positioning member 12 and the second positioning member 13 to the conveying assembly 11.

[0030] Specifically, the first waist-shaped hole 1112 and the second waist-shaped hole 1113 are respectively arranged at the positions where the support frame 111 is connected with the first positioning member 12 and the second positioning member 13, and the first connecting member 14 and the second connecting member 15 can be bolts.

[0031] When it is needed to adjust the interval between the first positioning member 12 and the second positioning member 13, it is only needed to loosen the first connecting member 14 and the second connecting member 15 and move the first positioning member 12 and the second positioning member 13, and when the first positioning member 12 and the second positioning member 13 are moved to the corresponding positions, the first connecting member 14 and the second connecting member 15 are tightened again to fix the first positioning member 12 and the second positioning member 13 on the support frame 111 respectively, so as to facilitate to improve the convenience of adjusting the interval between the first positioning member 12 and the second positioning member 13, and further facilitate to improve the versatility and efficiency of the tray feeding device 100 feeding the tray 300.

[0032] In other embodiments, the first connecting hole 1201 and the second connecting hole 1301 can also be respectively arranged at the positions where the conveying assembly 11 is connected with the first positioning member 12 and the second positioning member 13, and the first waist-shaped hole 1112 and the second waist-shaped hole 1113 are respectively arranged in the first positioning member 12 and the second positioning member 13, so that the first connecting member 14 can also fix the first positioning member 12 after being arranged in the first waist-shaped hole 1112 and connected with the first connecting hole 1201, and the second connecting member 15 can also fix the second positioning member 13 after being arranged in the second waist-shaped hole 1113 and connected with the second connecting hole 1301, and this arrangement also facilitates to improve the convenience of adjusting the interval between the first positioning member 12 and the second positioning member 13, which is not limited in the embodiments of the present application.

[0033] In other embodiments, two power members (not shown in the figure) can also be arranged to be connected with the first positioning member 12 and the second positioning member 13 respectively, so that the two power members can drive the first positioning member 12 and the second positioning member 13 to move to adjust the interval between the first positioning member 12 and the second positioning member 13, which is not limited in the embodiments of the present application.

[0034] In the embodiments, the first positioning member 12 and the second positioning member 13 each include a positioning portion 121 and a guide portion 122. The positioning portion 121 is slidingly connected to the support frame 111 of the conveying assembly 11 and extends along the conveying direction of the conveying assembly 11, the conveying direction of the conveying assembly 11 is the X-axis direction, the first connecting hole 1201 is arranged in the positioning portion 121 of the first positioning member 12, and the second connecting hole 1301 is arranged in the positioning portion 121 of the second positioning member 13. The guide portion 122 is connected to one side of the positioning portion 121 in the conveying direction of the conveying assembly 11, and the guide portion 122 of the first positioning member 12 and the guide portion 122 of the second positioning member 13 form an entrance 124 for the tray 300 to enter, and the size of the cross section of the entrance 124 gradually increases in the direction away from the positioning portion 122.

[0035] When the conveying assembly 11 drives the tray 300 to move between the first positioning member 12 and the second positioning member 13, the shape of the entrance 124 is trumpet-shaped because the size of the cross section of the entrance 124 gradually increases in the direction away from the positioning portion 122, thereby facilitating the accurate movement of the tray 300 driven by the conveying assembly 11 between the first positioning member 12 and the second positioning member 13. In addition, by arranging the positioning portion 121 to extend along the conveying direction of the conveying assembly 11, the contact area of the positioning portion 121 with the side wall of the tray 300 can be increased, thereby facilitating the accuracy of the abutment of the first positioning member 12 and the second positioning member 13 to the tray 300.

[0036] In the embodiment, the first positioning member 12 and the second positioning member 13 each further comprise a bent portion 123, the bent portion 123 is connected with the positioning portion 121 and located on the side of the positioning portion 121 away from the support frame 111 of the conveying assembly 11, and the distance between the bent portion 123 of the first positioning member 12 and the bent portion 123 of the second positioning member 13 gradually increases in the direction away from the support frame 111, thereby facilitating the tray 300 to be placed back to the feeding position 1111 by the transfer mechanism 20.

[0037] In the embodiment, the number of the first positioning member 12 and the second positioning member 13 is multiple, the multiple first positioning members 12 are arranged on one side of the support frame 111 of the conveying assembly 11 along the conveying direction of the conveying assembly 11, the multiple second positioning members 13 are arranged on the other side of the support frame 111 of the conveying assembly 11 along the conveying direction of the conveying assembly 11, and each two adjacent first positioning members 12 have a first avoiding opening 1202 and each two adjacent second positioning members 13 have a second avoiding opening 1302. When the transfer mechanism 20 grabs the tray 300 from the feeding position 1111, the multiple first avoiding openings 1202 and the multiple second avoiding openings 1302 avoid the transfer mechanism 20, thereby facilitating the convenience of the transfer mechanism 20 to grab the tray 300.

[0038] In the embodiment, the conveying assembly 11 further comprises multiple first passing openings 1114 and multiple second passing openings 1115, the multiple first passing openings 1114 and the multiple second passing openings 1115 are respectively one-to-one corresponding and communicating with the multiple first avoiding openings 1202 and the multiple second avoiding openings 1302. Specifically, the multiple first passing openings 1114 and the multiple second passing openings 1115 are arranged on the support frame 111. When the transfer mechanism 20 grabs the tray 300 from the feeding position 1111, the multiple first avoiding openings 1202, the multiple second avoiding openings 1302, the multiple first passing openings 1114 and the multiple second passing openings 1115 avoid the transfer mechanism 20, thereby facilitating the convenience of the transfer mechanism 20 to grab the tray 300.

[0039] In the embodiment, the conveying positioning mechanism 10 further comprises a sensing member 16 arranged on the first positioning member 12 or the second positioning member 13, and the sensing member 16 is configured to sense whether the conveying assembly 11 moves the tray 300 to between the first positioning member 12 and the second positioning member 13.

[0040] Specifically, the sensing member 16 can be a functional sensor such as a photoelectric sensor capable of sensing the position of an object, and the sensing member 16 is electrically connected to the rotating driving member 115 of the conveying assembly 11.

[0041] When the sensing member 16 senses that the conveying assembly 11 moves the tray 300 to between the first positioning member 12 and the second positioning member 13, the rotating driving member 115 stops driving the first transmission roller 112, the second transmission roller 113 and the conveying belt 114 to rotate according to the sensing signal of the sensing member 16. In this way, by arranging the sensing member 16, the accuracy of moving the tray 300 to between the first positioning member 12 and the second positioning member 13 by the conveying assembly 11 is improved.

[0042] In the embodiment, the sensing member 16 is a plurality of sensing members 16 arranged on the first positioning member 12 and the second positioning member 13 and located on the side away from each other of the first positioning member 12 and the second positioning member 13. The first positioning member 12 and the second positioning member 13 connected to the sensing member 16 are both provided with a through hole 1211, so that the sensing light fiber emitted by the sensing member 16 can pass through the through hole 1211 to sense the position of the tray 300.

[0043] Please refer to Figure 1 and Figure 2 again, in the embodiment, the transfer mechanism 20 comprises a lifting module 21 and a clamping assembly 22. The lifting module 21 is arranged on one side of the conveying assembly 11, and the lifting module 21 can be a linear slide. The clamping assembly 22 is connected to the lifting module 21, and the clamping assembly 22 is configured to clamp the positioned tray 300 under the driving of the lifting module 21 to perform feeding. In this way, the accuracy of clamping the tray 300 by the transfer mechanism 20 to perform feeding is improved.

[0044] In the embodiment, the clamping assembly 22 comprises a mounting seat 221, two clamping arms 222 and two clamping driving members 223. The mounting seat 221 is connected to the lifting module 21. The two clamping arms 222 are slidingly arranged on the mounting seat 221 and are spaced apart. The two clamping driving members 223 are arranged on the mounting seat 221 and are respectively connected to the two clamping arms 222. The two clamping driving members 223 can be telescopic cylinders, and the two clamping driving members 223 are configured to drive the two clamping arms 222 to approach or move away from each other to clamp or release the tray 300. In this way, the clamping assembly 22 has a simple structure and improves the accuracy of clamping the tray 300.

[0045] In the embodiment, the mounting base 221 has slide rails 2211 extending along the Y-axis direction, the slide rails 2211 can be multiple and divided into two equal groups, and the two clamping arms 222 are respectively and slidingly arranged on the two groups of slide rails 2211, thereby facilitating to improve the accuracy of the two clamping driving members 223 driving the two clamping arms 222 to approach or move away from each other.

[0046] In the embodiment, each clamping arm 222 includes a clamping member 2221 and multiple lifting members 2222. The clamping member 2221 is slidingly arranged on the mounting base 221 and connected with the corresponding clamping driving member 223. The multiple lifting members 2222 are arranged at intervals on the clamping member 2221, and the multiple lifting members 2222 are located on the side where the two clamping members 2221 approach each other, and each lifting member 2222 is convexly provided with a lifting protrusion 2222a on the side away from the corresponding clamping member 2221. Specifically, the clamping member 2221 is slidingly arranged on the slide rail 2211, and the multiple lifting members 2222 are arranged at intervals on the corresponding clamping member 2221 along the X-axis direction.

[0047] By arranging the multiple lifting members 2222 and convexly providing the lifting protrusion 2222a on the side of each lifting member 2222 away from the corresponding clamping member 2221, when the two clamping arms 222 clamp the tray 300, the lifting member 2222 abuts against the side wall of the tray 300, and the lifting protrusion 2222a abuts against the bottom of the tray 300, thereby effectively avoiding the tray 300 from being skewed when the clamping assembly 22 clamps the tray 300, and facilitating to improve the accuracy of the tray 300 feeding by the transfer mechanism 20.

[0048] In the embodiment, the clamping assembly 22 further includes two limiting members 224, which are arranged at intervals on the mounting base 221 and respectively located on the side where the two clamping arms 222 approach each other, and the two limiting members 224 are used to abut against the two clamping arms 222 respectively when the two clamping driving members 223 drive the two clamping arms 222 to approach each other, so as to limit the distance of the two clamping arms 222 approaching each other, thereby effectively avoiding the two clamping arms 222 from being injured due to the too small distance of approaching each other.

[0049] In the embodiment, the two limiting members 224 can be oil pressure buffers. The oil pressure buffer has a buffering function, thereby effectively reducing the probability of damaging the clamping arm 222 and the tray 300 due to the rigid abutment of the two clamping arms 222 and the tray 300.

[0050] In summary, the tray feeding device 100 of the embodiment of the present application carries the tray 300 through the setting of the conveying assembly 11 and drives the tray 300 to move, sets the first positioning piece 12 and the second positioning piece 13 to abut and position the tray 300 from both sides, and sets the transfer mechanism 20 to pick up the positioned tray 300 for feeding, thereby realizing the function of automatically feeding the tray 300 and improving the feeding efficiency of the tray 300. Through the setting of the first positioning piece 12 and the second positioning piece 13 which are slidingly connected at opposite sides of the conveying assembly 11, when the size of the tray 300 changes, it is only needed to move the first positioning piece 12 and the second positioning piece 13 and adjust the spacing between the first positioning piece 12 and the second positioning piece 13, then the first positioning piece 12 and the second positioning piece 13 can re-position the tray 300, the process of debugging the tray feeding device 100 is simple and the time is relatively short, thereby improving the versatility of the tray feeding device 100 in feeding the tray 300 and further improving the feeding efficiency of the tray 300.
