[0037] As Figure 1 shown, the embodiment of the present application provides a conveying mechanism 100, mainly used for conveying product parts from one process to the next process. The conveying mechanism 100 comprises a transfer assembly 110.

[0038] After the parts of the corresponding product are processed, they need to be placed on the carrier tape or the packaging tray for packaging treatment, so as to facilitate product storage, protection, handling, etc.

[0039] The transfer assembly 110 is used for loading the packaging tray loaded with the parts or directly loading the parts unloaded from the flow line.

[0040] The transfer assembly 110 includes a lifting platform 111, a fixed support 112, a movable support 113 and a width adjusting member 114 arranged on the lifting platform 111.

[0041] As shown in Figure 1 and Figure 2 , the fixed support 112 and the movable support 113 are arranged in the first direction D1, and the width adjusting member 114 drives the movable support 113 to move towards or away from the fixed support 112.

[0042] In one embodiment, the lifting platform 111 is plate-shaped, and a plurality of hollow holes 1111 are arranged on the lifting platform 111 to reduce the weight of the lifting platform 111 and reduce energy consumption.

[0043] The transfer assembly 110 of the present application adjusts the distance between the fixed support 112 and the movable support 113 through the width adjusting member 114 to adapt to the conveying of parts of different widths, so that the conveying mechanism 100 can convey parts of various specifications, and has the advantages of convenient adjustment and wide application range.

[0044] In some embodiments, the width adjusting member 114 includes at least one sliding rail 1141, at least one sliding block 1142 and a first driver 1143.

[0045] The sliding rail 1141 extends in the first direction D1, and the sliding rail 1141 is arranged on the side of the fixed support 112 close to the movable support 113. For example, as shown in Figure 1 , the number of sliding rails 1141 is two, and the two sliding rails 1141 are arranged in parallel in the second direction D2.

[0046] One sliding block 1142 is arranged on one sliding rail 1141 for sliding, and the movable support 113 is connected with the sliding block 1142. The sliding block 1142 moves on the sliding rail 1141 to drive the movable support 113 to move towards or away from the fixed support 112.

[0047] The output end of the first driver 1143 is connected with the movable plate 1131, and drives the movable support 113 to move on the sliding rail 1141.

[0048] For example, the first driver 1143 is a pneumatic cylinder, a servo motor or a stepper motor.

[0049] As shown in Figure 1 The first driver 1143 is fixedly connected with the lifting platform 111, and the output end of the first driver 1143 is connected with the side of the movable support 113 away from the fixed support 112, so that the first driver 1143 drives the movable support 113 to move along the first direction D1.

[0050] It should be noted that the first direction D1 is the length direction of the lifting platform 111, the second direction D2 is the width direction of the lifting platform 111, and the third direction D3 is the thickness direction of the lifting platform 111.

[0051] In some embodiments, the fixed support 112 includes a fixed plate 1121 and a first conveying belt 1122, and the movable support 113 includes a movable plate 1131 and a second conveying belt 1132. The fixed plate 1121 extends along the second direction D2, and the fixed plate 1121 is fixed on the lifting platform 111. The first conveying belt 1122 is arranged on the side of the fixed plate 1121 close to the movable plate 1131, and the first conveying belt 1122 is arranged spaced apart from the lifting platform 111. The movable plate 1131 extends along the second direction D2, and the movable plate 1131 is connected with the sliding block 1142. The second conveying belt 1132 is arranged on the side of the movable plate 1131 close to the fixed plate 1121, and the second conveying belt 1132 is arranged spaced apart from the lifting platform 111.

[0052] The distance between the movable support 113 and the fixed support 112 is adjusted by the width adjusting member 114, and the distance between the first conveying belt 1122 and the second conveying belt 1132 is adjusted synchronously, so that different specifications of parts can be placed on the first conveying belt 1122 and the second conveying belt 1132 for transmission.

[0053] The first conveying belt 1122 and the second conveying belt 1132 form a transfer station P1, which is used to place parts of different specifications.

[0054] The first conveying belt 1122 and the second conveying belt 1132 rotate to move the parts from the previous process to the transfer station P1, and then rotate again to move the parts from the transfer station P1 to the next process.

[0055] In some embodiments, the fixed support 112 includes a second driver 1123, and the second driver 1123 drives the first conveying belt 1122. The movable support 113 includes a third driver 1133, and the third driver 1133 drives the second conveying belt 1132.

[0056] For example, the second driver 1123 is a servo motor or a stepper motor.

[0057] Exemplarily, the third driver 1133 adopts a servo motor or a stepping motor.

[0058] The feeding end of the transfer station P1 is provided with a feeding sensor 1151, and the discharging end of the transfer station P1 is provided with a discharging sensor 1152. The second driver 1123 and the third driver 1133 are electrically connected with the feeding sensor 1151 respectively, and the second driver 1123 and the third driver 1133 are electrically connected with the discharging sensor 1152 respectively.

[0059] As shown in Figure 1 , the feeding sensor 1151 is arranged on the left side or the right side of the lifting platform 111, and the discharging sensor 1152 is correspondingly arranged on the right side or the left side of the lifting platform 111.

[0060] Exemplarily, the feeding sensor 1151 adopts an infrared sensor, and the discharging sensor 1152 adopts an infrared sensor.

[0061] In some embodiments, as shown in Figure 2 , in the first direction D1, the length of the slide rail 1141 is L1, and the distance between the slide block 1142 and the fixed plate 1121 is L2, which satisfies: 0.3≤L2 / L1≤0.9.

[0062] The ratio of L2 / L1 is 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, etc., which is not limited to the example ratio. In this way, the slide block 1142 has a larger activity space on the slide rail 1141, which facilitates flexible adjustment of the distance between the first conveying belt 1122 and the second conveying belt 1132, so that the transmission mechanism 100 can transport parts of various specifications, and has the advantages of convenient adjustment and wide application range.

[0063] It can be understood that the first conveying belt 1122 and the second conveying belt 1132 are arranged opposite to each other. When L2 / L1<0.3, the first conveying belt 1122 and the second conveying belt 1132 are likely to contact each other and be damaged. When L2 / L1>0.9, the slide block 1142 is likely to be separated from the slide rail 1141.

[0064] In some embodiments, the feeding sensor 1151 and the discharging sensor 1152 are both arranged on the side of the fixed plate 1121 away from the lifting platform 111. In this way, the positions of the feeding sensor 1151 and the discharging sensor 1152 are exposed, which facilitates maintenance.

[0065] In some embodiments, as shown in Figure 2 , the distance between the feeding sensor 1151 and the discharging sensor 1152 is L3, and the length of the first conveying belt is L4, which satisfies: 0.8≤L3 / L4≤0.9.

[0066] The ratio of L3 / L4 is 0.80, 0.81, 0.82, 0.83, 0.84, 0.85, 0.86, 0.87, 0.88, 0.89, 0.9, and the like, which are not limited to the examples. In this way, the feeding sensing piece 1151 and the discharging sensing piece 1152 are both located within the stroke range of the first conveying belt 1122. At least part of the spare part is located on the first conveying belt 1122, and the feeding sensing piece 1151 senses whether the feeding is performed. Such a sensing mode can improve the sensitivity and accuracy of sensing.

[0067] When L3 / L4 < 0.8, the feeding sensing piece 1151 is set to a stroke progress that is too deep, which reduces the sensitivity. When L2 / L1 > 0.9, the feeding sensing piece 1151 is set at the end of the first conveying belt 1122, and the spare part is not in contact with the first conveying belt 1122 to perform feeding sensing, which reduces the accuracy of sensing.

[0068] In some embodiments, the transfer assembly 110 further comprises a first limiting piece (not shown in the figure) and a second limiting piece (not shown in the figure).

[0069] The first limiting piece and the second limiting piece are both in the shape of a long strip. The first limiting piece is arranged on the side of the first conveying belt 1122 away from the lifting platform 111, and is detachably connected with the fixed plate 1121; the second limiting piece is arranged on the side of the second conveying belt 1132 away from the lifting platform 111, and is detachably connected with the movable plate 1131. By arranging the first limiting piece and the second limiting piece, the spare part can be limited on the first conveying belt 1122 and the second conveying belt 1132, so as to avoid the spare part from being separated from the conveying belt.

[0070] In some embodiments, the conveying mechanism 100 further comprises a lifting assembly 120.

[0071] The lifting assembly 120 is arranged on the side of the lifting platform 111 close to the fixed support 112. The output end of the lifting assembly 120 is connected with the lifting platform 111, and drives the lifting platform 111 to move along the third direction D3.

[0072] In one embodiment, as shown in Figure 3 The lifting assembly 120 comprises a fourth driver 121, a lifting track 122, and a lifting sliding block 123. The lifting track 122 extends along the third direction D3. The lifting sliding block 123 is connected with the lower part of the lifting platform 111, and the fourth driver 121 drives the lifting sliding block 123 to move on the lifting track 122.

[0073] The lifting assembly 120 further comprises a fixing member 124 connected to the lifting rail 122 away from the lifting slider 123, so as to fix or detach the lifting assembly 120 from other production equipment on the surface mounting assembly line.

[0074] In some embodiments, as shown in Figures 1 to 3 The lifting rail 122 and the lifting platform 111 are respectively provided with tank chains. The tank chains are used to protect the cables connected to the above-mentioned various drivers, the feeding sensor 1151, the discharging sensor 1152 and other electrical elements, so as to ensure that the cables are not pulled or worn in frequent movement.

[0075] The working process of the conveying assembly is as follows:

[0076] Adjust the distance between the fixed plate 1121 and the movable plate 1131 through the width adjusting member 114;

[0077] The fourth driver 121 drives the lifting slider 123 to move, so as to adjust the height of the lifting platform 111;

[0078] The conveying mechanism 100 is connected to the unloading position of the previous process, and the parts are moved from the previous process to the transfer assembly 110;

[0079] The feeding sensor detects the feeding, so that the second driver 1123 and the third driver 1133 are started;

[0080] The discharging sensor 1152 detects the position, so that the second driver 1123 and the third driver 1133 are started and stopped;

[0081] The fourth driver 121 drives the lifting slider 123 to move, so that the lifting platform 111 moves to the height of the next process;

[0082] The conveying mechanism 100 is connected to the unloading position of the next process;

[0083] The second driver 1123 and the third driver 1133 are started, and the parts are moved from the transfer assembly 110 to the next process;

[0084] The discharging sensor 1152 detects no feeding, so that the second driver 1123 and the third driver 1133 are started and stopped.

[0085] The present application further provides a surface mounting assembly line comprising the conveying mechanism 100 of any of the above-mentioned embodiments, so as to have all the beneficial effects of the conveying mechanism 100 of any of the above-mentioned embodiments, which will not be repeated here.
