[0007] By adopting the above technical scheme, the workpiece is placed on the support seat in a superimposed manner. When the first driving member rotates, the support seat is driven to rise along the first slide seat by the first screw rod. At this time, the first telescopic member drives the suction cup member to press down to adsorb the workpiece on the suction cup member. Then the second driving member drives the suction cup member to be located on the pushing assembly through the second screw rod to place the workpiece on the disc. At this time, according to the pushing direction of the workpiece, the third driving member drives the disc to rotate so that the workpiece faces the direction in which it needs to be transported. When the second telescopic member is extended and retracted, the workpiece is pushed to the designated area, thereby completing the automatic loading process. Through this structure, the workpiece is automatically loaded to replace the defects of manual loading, the process has better production efficiency, is safer, and has strong overall practicality.

[0008] Optionally, it also includes a workpiece table, and the lifting mechanism, clamping mechanism and pushing mechanism are all installed on the workpiece table. The workpiece table is located on the outer periphery of the support seat and is provided with a plurality of protective rollers. The support seat is provided with a waist-shaped groove, and the protective rollers are movably inserted into the waist-shaped groove.

[0009] By adopting the above technical solution and utilizing a plurality of protective rollers, the position of the workpiece on the support seat can be effectively limited so that the workpiece will not deviate, thereby facilitating the suction cup to more stably absorb the workpiece to realize the loading process.

[0010] Optionally, the workpiece table is further provided with a control roller on the periphery of the support seat, the control roller is hinged to the workpiece table, an open groove is provided on the support seat, and the control roller abuts against the open groove.

[0017] By adopting the above technical solution, each time the vacuum suction cup clamps a workpiece, the first screw drives the support seat to raise the thickness of the single workpiece, so that the suction cup clamps the position height the same each time. When the workpiece on the support seat is completely clamped, the first screw drives the support seat to drop to the initial position, and the workpiece continues to be placed on the support seat. The process has good rhythm consistency and is easy to operate.

[0018] Optionally, an extension block is provided at one end of the disc away from the second telescopic member.

[0020] Optionally, a limiting plate is connected to the second telescopic member.

[0021] By adopting the above technical solution and utilizing the provided limiting piece, when the second telescopic member pushes the workpiece, the contact area with the workpiece can be increased, thereby better controlling the pushing direction of the workpiece.

[0022] In summary, the present application includes at least one of the following beneficial effects:

Then the second driving member drives the suction cup member to be located on the pushing assembly through the second screw rod to place the workpiece on the disc. At this time, according to the direction of pushing the workpiece, the third driving member drives the disc to rotate so that the workpiece faces the direction to be transported.

When the first driving member 130 moves the workpiece 500, the support seat 140 is driven to rise and fall along the first slide 110 through the first screw rod 120.

[0038] In some embodiments, the clamping mechanism 200 includes a second slide 210, a second lead screw 220, a first telescopic member 230 and an abutment member 240, the abutment member 240 includes a fixed plate 241 and a suction cup member 242, the suction cup member 242 is located above the support seat 140, the second slide 210 is horizontally fixed on the workpiece table 400, the fixed member is slidably connected to the second slide 210, the second lead screw passes through the fixed plate 241 and is rotatably connected to the second slide 210, the second lead screw is connected to the second driving member 260, the second driving member 260 is a servo motor, which can rotate forward or reverse, and when the second driving member 260 moves the workpiece 500, the second lead screw drives the fixed plate 241 to move left or right.

[0039] Among them, the suction cup member 242 is vertically slidably connected to the fixed plate 241, and the fixed plate 241 is located above the suction cup member 242 and is provided with a first telescopic member 230. The first telescopic member 230 is a telescopic cylinder, and the output end of the first telescopic member 230 is connected to the suction cup member 242. When the first telescopic member 230 is extended, the suction cup member 242 is driven to move downward; when the first telescopic member 230 is shortened, the suction cup member 242 is driven to rise.

[0040] In some embodiments, the pushing assembly includes a support column 310, a disc 320, a third driving member 330 and a second telescopic member 340. The support column 310 is vertically fixed to the workpiece table 400, the third driving member 330 is installed on the top of the support column 310, the output end of the third driving member 330 faces upward, and the disc 320 is installed on the output end of the third driving member 330. The third driving member 330 is a servo motor that can drive the disc 320 to rotate, and the second telescopic member 340 is installed on the circumferential side of the disc 320.

[0041] In some embodiments, a plurality of vacuum suction cups 250 are provided on the side of the suction cup member 242 facing the support seat 140. The vacuum suction cups 250 are connected to an external vacuum device (not shown in the figure). When negative pressure is generated in the vacuum suction cups 250, the workpiece 500 can be firmly adsorbed by abutting against the workpiece 500. When the workpiece 500 is ready to be placed on the disc 320, the negative pressure in the vacuum suction cups 250 changes to zero pressure, and the workpiece 500 is detached and freely falls onto the disc 320.

[0042] Specifically, when the vacuum suction cup 250 sucks the workpiece 500 on the support seat 140 onto the disc, the first screw rod 120 drives the support seat 140 to rise along the first slide seat 110, and at the same time the second telescopic pushes the workpiece 500 off the disc 320. Each time the vacuum suction cup 250 clamps a workpiece 500, the first screw rod 120 drives the support seat 140 to raise the thickness of the single workpiece 500, so that the height of the clamping position of the suction cup 242 is the same each time. When the workpiece 500 on the support seat 140 is completely clamped, the first screw rod 120 drives the support seat 140 to descend to the initial position, and the workpiece 500 continues to be placed on the support seat 140.

[0043] See also Figure 1 and Figure 2 The workpiece table 400 is located on the periphery of the support seat 140 and is provided with a strip protective roller 410. The protective roller 410 is vertically abutted against the workpiece table 400. A waist-shaped groove 141 is opened on the support seat 140. The protective roller 410 is movably inserted into the waist-shaped groove 141. By using a plurality of protective rollers 410, the position of the workpiece 500 on the support seat 140 can be effectively limited so that the workpiece 500 will not deviate. At the same time, by using the opened waist-shaped groove 141, the position of each protective roller 410 on the support seat 140 can be adjusted to better limit the workpiece 500, so that the workpiece 500 is neatly stacked vertically, which is convenient for the suction cup 242 to more stably adsorb the workpiece 500 to realize the loading process.

[0044] In some embodiments, a control roller 420 is provided on the periphery of the workpiece table 400 located on the support seat 140, and the control roller 420 is vertically hinged on the workpiece table 400. An opening groove 142 is opened on the side of the support seat 140 facing the control roller 420, and the control roller 420 abuts against the opening groove 142. When the control roller 420 is disengaged from the opening groove 142, it is convenient to place the workpiece 500 on the support seat 140. After the workpiece 500 is placed, the control roller 420 abuts against the opening groove 142, and cooperates with the protective roller 410 to realize the protection of the periphery of the workpiece 500.

[0045] It should be noted that in this embodiment, the control roller 420 is hinged, which is convenient for the process to quickly operate the control roller 420 to abut or disengage from the opening groove 142. The workpiece table 400 is provided with a magnet 423 at the bottom of the control roller 420. When the control roller 420 is disengaged from the opening groove 142, the control roller 420 is separated from the magnet 423; when the control roller 420 abuts against the opening groove 142, the control roller 420 abuts against the magnet 423, and the process realizes the rapid fixation of the control roller 420.

[0046] See also Figure 3 An extension block 321 is provided at one end of the disc 320 away from the second telescopic member 340, so that the second telescopic member 340 can push the workpiece 500 away from the disc 320, so that the disc 320 can be transported to the outside in a horizontal state.

[0047] In this embodiment, a limiting plate 350 is connected to the output end of the second telescopic member 340. The limiting plate 350 is V-shaped, so that when the second telescopic member 340 pushes the workpiece 500, it can increase the contact area with the workpiece 500 and better control the pushing direction of the workpiece 500.

[0048] The implementation principle of the embodiment of the present application is as follows: the workpiece 500 is placed on the support seat 140 in a superimposed manner. When the first driving member 130 rotates, the support seat 140 is driven to rise along the first slide seat 110 through the first screw rod 120. At this time, the first telescopic member 230 drives the suction cup member 242 to press down, and the workpiece 500 is adsorbed on the suction cup member 242. Then the second driving member drives the suction cup member 242 to be located on the pushing assembly through the second screw rod, and the workpiece 500 is placed on the disc 320. At this time, according to the pushing direction of the workpiece 500, the third driving member 330 drives the disc 320 to rotate, so that the workpiece 500 is facing the direction to be transported. When the second telescopic member 340 is extended and retracted, the workpiece 500 is pushed to the designated area, thereby completing the automatic loading process.

[0049] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
