The clamping component 12 includes two jaws 121, and the two jaws 121 cooperate to clamp the piece 100. The pneumatic finger 2 is connected to the material trays 11 of the two conveying modules 1 and is used to drive the two conveying modules 1 to move away from or close to each other horizontally.

[0062] For the multi-piece clamping and variable-spacing mechanism of the present utility model, in the initial state, the distance between the two conveying modules 1 is relatively close to match the distance between two groups of pieces 100 located at the processing position. The jaws 121 of the two conveying modules 1 respectively clamp the two groups of pieces 100. Then, the pneumatic finger 2 drives the two conveying modules 1 to move away from each other, so that the distance between the two groups of pieces 100 is equal to the distance between two adjacent pieces 100 on the same conveying module 1. Subsequently, the two conveying modules 1 place the two groups of pieces 100 at intervals into the receiving grooves 2001 in one half of the receiving basket 200. The pneumatic finger 2 drives the two conveying modules 1 to move close to each other again, so that the distance between the two conveying modules 1 is relatively close again, clamps the subsequent two groups of pieces 100, and the pneumatic finger 2 drives the two conveying modules 1 to move away from each other again, so that the distance between the two groups of pieces 100 is equal to the distance between two adjacent pieces 100 on the same conveying module 1. The two conveying modules 1 place the two groups of pieces 100 at intervals into the remaining half of the receiving grooves 2001 in the receiving basket 200, thereby filling a receiving basket 200 and making the pieces 100 closely arranged in the receiving basket 200. For the multi-piece clamping and variable-spacing mechanism of the present utility model, by adjusting the distance between the two conveying modules 1 through the pneumatic finger 2, multiple pieces 100 can be placed into the receiving grooves 2001 at intervals in the receiving basket 200 at the same time, and it can also match the distance between two groups of pieces 100 located at the processing position, effectively improving the working efficiency.

A plurality of sets of clamping assemblies 12 are arranged on the two support arms 112 in the transverse direction, and the two clamping assemblies 12 in each set are respectively arranged on the two support arms 112. The tray 11 with the above structure is simple in structure and light in weight, making the pneumatic fingers 2 drive the two trays 11 to move smoothly.

[0065] Please refer to Figure 2 , the conveying module 1 further includes a plurality of capacitive proximity sensors 13, which are connected to the tray 11, and the capacitive proximity sensors 13 are arranged between the two clamping assemblies 12 in each set.

[0066] Please refer to Figure 2 and Figure 7 , each conveying module 1 includes two sets of clamping assemblies 12, and each conveying module 1 includes two capacitive proximity sensors 13. The conveying module 1 further includes a connecting frame 14, which includes a frame body 141 and two lugs 142. The frame body 141 is located in the hollow area of the tray 11, and the frame body 141 includes two first rods 1411 and two second rods 1412. The two first rods 1411 are arranged in the transverse direction and are parallel to each other, and the two capacitive proximity sensors 13 are respectively arranged on the bottom surfaces of the two first rods 1411. The two second rods 1412 are arranged in the longitudinal direction and are parallel to each other, and the two lugs 142 are respectively connected to the outer sides of the two second rods 1412, and the bottom surfaces of the two lugs 142 are respectively connected to the top surfaces of the two support arms 112. The connecting frame 14 is connected to the tray 11 through the two lugs 142, and the two capacitive proximity sensors 13 can be fixed simultaneously through the connecting frame 14. The above structure makes the assembly of the conveying module 1 simple and the structure compact.

[0067] Please refer to Figure 6 and Figure 7 , a positioning groove 1121 is provided on the top surface of the support arm 112, and the lug 142 is arranged in the positioning groove 1121. Through this structure, it is convenient to accurately install the connecting frame 14 on the two support arms 112.

[0068] Please refer to Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9, the support arm 112 is provided with a plurality of accommodating structures 1122, and the accommodating structures 1122 are arranged in one-to-one correspondence with the clamping assemblies 12. The accommodating structure 1122 includes an accommodating groove 11221 and two rotating grooves 11222, and the two rotating grooves 11222 are arranged on the transverse sides of the accommodating groove 11221.

[0069] The clamping jaw 121 includes a driving section 1211 and a clamping section 1212, which are connected in a bent shape, and a positioning hole 1213 is arranged at the connection part of the two. The driving section 1211 is movably arranged in the accommodating groove 11221, and the clamping section 1212 extends below the support arm 112.

[0070] The clamping assembly 12 further includes a fixed block 122, two positioning pins 123, two torsion springs 124 and a piston 125. The fixed block 122 is connected to the top surface of the support arm 112. The fixed block 122 is provided with an air passage 1221, and the air passage 1221 is provided with an air inlet 1222 and an air outlet 1223. The air inlet 1222 is used to communicate with the air source device, and the air outlet 1223 is located at the bottom of the fixed block 122, and its position corresponds to the accommodating groove 11221. The two positioning pins 123 are respectively rotatably arranged in the two rotating grooves 11222 and extend longitudinally, and the positioning pin 123 passes through the positioning hole 1213. The two torsion springs 124 are respectively sleeved on the two positioning pins 123. One end of the torsion spring 124 abuts against the support arm 112, and the other end abuts against the driving section 1211. The torsion spring 124 is used to provide an elastic force so that the driving section 1211 rotates upward, so that the clamping section 1212 moves in the direction close to the clamping section 1212 of the other clamping jaw 121, so that the two clamping jaws 121 clamp the sheet 100. The piston 125 is movably arranged in the air passage 1221 in the vertical direction and is used to push the two driving sections 1211 to rotate downward, so that the clamping sections 1212 of the two clamping jaws 121 move away from each other, so that the two clamping jaws 121 release the sheet 100.

[0071] The air source device blows air into the air passage 1221 through the air inlet 1222, so that the piston 125 moves downward, thereby pushing the two driving sections 1211 to rotate downward, so that the clamping sections 1212 of the two clamping jaws 121 move away from each other, so that the two clamping jaws 121 release the sheet 100, and at the same time squeeze both ends of the torsion spring 124, so that the torsion spring 124 has a resilience. After the air source device stops blowing air, the resilience of the torsion spring 124 makes the driving section 1211 rotate upward, so that the clamping section 1212 moves in the direction close to the clamping section 1212 of the other clamping jaw 121, so that the two clamping jaws 121 clamp the sheet 100. Through the above structure, the two clamping jaws 121 can be controlled to open and close flexibly.

[0072] Please refer to Figure 4 、 Figure 5 and Figure 9, the clamping assembly 12 further includes steel balls 126 which are vertically movably arranged between the bottom end of the piston 125 and the driving sections 1211 of the two jaws 121.

The bottom of the steel ball 126 abuts against the inclined surfaces 12111 of the two jaws 121. When the piston 125 moves downward, it pushes the steel balls 126 to move downward, thereby pushing the two jaws 121 to rotate into an open state. Through the above structure, the contact area between the steel balls 126 and the driving sections 1211 of the two jaws 121 can be increased, making the rotation of the two jaws 121 stable.

[0073] Please refer to Figure 10 , and at the same time please refer to Figure 4 . A limiting groove 1252 is provided at the bottom of the piston 125, and the shape of the limiting groove 1252 matches the shape of the steel ball 126. The top of the steel ball 126 is arranged in the limiting groove 1252. Through the above structure, the steel ball 126 can be prevented from shifting during the movement.

[0074] Please refer to Figure 4 and Figure 10 , the piston 125 is provided with two spaced plug rings 1251, and the clamping assembly 12 further includes a sealing ring 127 which is arranged between the two plug rings 1251, and the peripheral edge of the sealing ring 127 abuts against the inner wall of the air passage 1221. Through the above structure, the gas blown in by the external air source device can be prevented from leaking to the bottom end of the piston 125, which is convenient for pushing the piston 125.

[0075] The working process of the multi-piece clamping variable pitch mechanism of the preferred embodiment of the present utility model:

[0076] In the initial state, the distance between the two conveying modules 1 is relatively close to match the distance between the two sets of wafers 100 located at the processing position. The air source device blows air into the air duct 1221 through the air inlet 1222, causing the piston 125 to move downward, thereby pushing the steel ball 126 downward, and further pushing the two driving segments 1211 to rotate downward, so that the clamping segments 1212 of the two jaws 121 move away from each other, and the two jaws 121 are in an open state. When the capacitive proximity sensor 13 senses the wafer 100, the air source device stops blowing air, and the resilience of the torsion spring 124 causes the driving segment 1211 to rotate upward, so that the clamping segment 1212 moves in the direction of approaching the clamping segment 1212 of the other jaw 121, and the two jaws 121 close to clamp the wafer 100. The pneumatic finger 2 drives the two conveying modules 1 to move away from each other, so that the distance between the two sets of wafers 100 is equal to the distance between two adjacent wafers 100 on the same conveying module 1. Subsequently, the two conveying modules 1 place the two sets of wafers 100 at intervals into half of the storage slots 2001 of the storage basket 200. The pneumatic finger 2 drives the two conveying modules 1 to move closer to each other, and once again makes the distance between the two conveying modules 1 relatively close to clamp the subsequent two sets of wafers 100. The pneumatic finger 2 drives the two conveying modules 1 to move away from each other again, so that the distance between the two sets of wafers 100 is equal to the distance between two adjacent wafers 100 on the same conveying module 1. The two conveying modules 1 place the two sets of wafers 100 at intervals into the remaining half of the storage slots 2001 of the storage basket 200, thereby filling a storage basket 200 and making the wafers 100 tightly arranged in the storage basket 200.

[0077] This is the working process of the multi-wafer clamping and variable-distance mechanism of this preferred embodiment.

[0078] For the multi-piece clamping variable pitch mechanism of the present utility model, in the initial state, the distance between the two conveying modules is relatively close to match the distance between the two groups of pieces located at the processing position. The clamping jaws of the two conveying modules respectively clamp the two groups of pieces. Then, the pneumatic fingers drive the two conveying modules to move away from each other, so that the distance between the two groups of pieces is equal to the distance between two adjacent pieces on the same conveying module. Subsequently, the two conveying modules place the two groups of pieces at intervals into half of the receiving slots in the receiving basket. The pneumatic fingers drive the two conveying modules to move closer to each other again, making the distance between the two conveying modules relatively close again, clamping the subsequent two groups of pieces. The pneumatic fingers drive the two conveying modules to move away from each other again, so that the distance between the two groups of pieces is equal to the distance between two adjacent pieces on the same conveying module. The two conveying modules place the two groups of pieces at intervals into the remaining half of the receiving slots in the receiving basket, thus filling a receiving basket and making the pieces tightly arranged in the receiving basket. For the multi-piece clamping variable pitch mechanism of the present utility model, by adjusting the distance between the two conveying modules through the pneumatic fingers, it can not only place multiple pieces into the receiving slots in the receiving basket at intervals, but also match the distance between the two groups of pieces located at the processing position, effectively improving the working efficiency.
