[0032] Please see Figure 1 This embodiment provides a workpiece loading device for conveying a loading plate 100 containing multiple workpieces to a loading area 300 and for recycling the loading plate 100. The workpiece loading device includes:

[0033] The feeding bracket 1 is provided with a feeding limiting groove 11 for the feeding plate 100 to slide in the vertical direction. A clamping cylinder 12 is installed on one side of the feeding limiting groove 11. The side wall of the feeding plate 100 has a clamping groove 200 for the output end of the clamping cylinder 12 to be inserted.

[0034] The recycling bracket 2 is provided with a recycling limiting groove 21 for the feeding plate 100 to slide in the vertical direction, and an elastic limiter 22 is installed on one side of the recycling limiting groove 21.

[0035] The transport mechanism 3 includes a conveyor belt 31, a transport cylinder 32, and a tray 33. The conveyor belt 31 passes through the bottom of the loading area 300, the loading support 1, and the recycling support 2. The transport cylinder 32 is mounted on the conveyor belt 31. The tray 33 is mounted on the output end of the transport cylinder 32. The tray 33 is used to drive the loading plate 100 to move at the bottom of the loading area 300, the loading support 1, and the recycling support 2.

[0036] Based on the above structure, during use, the operator can pre-place a preset number of loading plates 100 containing workpieces in the loading limit groove 11 of the loading bracket 1. In the default state, the conveyor belt 31 in the transport mechanism 3 drives the transport cylinder 32 to move to the bottom position of the loading bracket 1, and causes its pallet 33 to lift and support the bottom loading plate 100 in the loading limit groove 11, so that the height of the other loading plate 100 above the bottom loading plate 100 is set at the position of the clamping cylinder 12. At this time, the clamping cylinder 12 is used to clamp the other loading plate 100 above the bottom loading plate 100, and the output end of the clamping cylinder 12 is inserted into the clamping groove 200.

[0037] Then, the tray 33 moves the bottommost loading plate 100, causing it to move to the loading area 300 and pick up the workpieces on the loading plate 100 in the loading area 300.

[0038] After all the workpieces have been picked up, the pallet 33 moves the loading plate 100 to the bottom of the recycling bracket 2. The transport cylinder 32 then lifts the loading plate 100 upwards by the pallet 33. When the loading plate 100 passes the elastic limiter 22 in the recycling limit groove 21, it interferes with the elastic limiter 22. After passing the elastic limiter 22, the loading plate 100 is supported by the elastic limiter 22 and does not fall. At this time, the pallet 33 resets and the next cycle begins.

[0039] The output end of the clamping cylinder 12 and the output end of the transport cylinder 32 mentioned above can be configured as a motor shaft assembly for transmission, which drives the corresponding downstream components to reciprocate through the stroke motion.

[0040] In the above operation, the feeding plate 100 can be transferred between the feeding support 1 and the recycling support 2 by the transport mechanism 3, which has a high feeding efficiency. Specifically, a certain amount of feeding plates 100 can be pre-stored in the feeding limiting groove 11. After the feeding plate 100 is fed by the transport mechanism 3, it can also be transported to the corresponding recycling limiting groove 21 at the same time, realizing a three-in-one rapid operation of feeding, picking up and recycling, which can significantly improve the feeding operation efficiency.

[0041] Based on the above scheme, the loading plate 100 has a first station, a second station, and a third station. At the first station, the loading plate 100 is held in the loading limiting groove 11 by the clamping cylinder 12, awaiting the next transport loading. At the second station, the loading plate 100 is lifted by the pallet 33 in the loading area 300. At the third station, the loading plate 100 is lifted by the pallet 33 over the elastic limiter 22 and placed in the recycling limiting groove 21. The first, second, and third stations correspond to the corresponding height positions in the loading limiting groove 11, the loading area 300, and the recycling bracket 2, respectively. They are connected in series by the conveyor belt 31 in the transport mechanism 3, and vertical transportation is achieved by the transport cylinder 32 cooperating with the pallet 33 to move up and down. Its streamline organization is simple and clear, and easy to maintain.

[0042] Please see Figure 2 The elastic limiter 22 includes a limiting piece 221 and an elastic push rod 222. The first end of the limiting piece 221 is hinged to the recycling bracket 2, and the second end of the limiting piece 221 is connected to the recycling bracket 2 via the elastic push rod 222. The limiting piece 221 has an inclined surface facing the bottom of the recycling limiting groove 21 and a top surface connected to the inclined surface. Before the feeding plate 100 reaches the third station, the inclined surface abuts against the feeding plate 100, compressing the elastic push rod 222. When the feeding plate 100 reaches the third station, the limiting piece 221 resets, and the top surface supports the bottom of the feeding plate 100. During the ascent of the feeding plate 100, its edge presses against the inclined surface of the limiting piece 221. After disengaging from the limiting piece 221, the limiting piece 221 naturally resets with the aid of the elastic push rod 222.

[0043] Of course, the number of the aforementioned elastic limiters 22 is set to multiple, and the multiple elastic limiters 22 are arranged at intervals around the recycling limit groove 21. Figure 1 In the process, two elastic limiters 22 can be set at one edge of the feeding plate 100, and a total of four elastic limiters 22 can be set in a symmetrical set to ensure stable support for the feeding plate 100.

[0044] Of course, in another embodiment, any one-way limiting mechanism that can limit the vertical direction of the feed plate 100 can replace the function of the elastic limiter 22.

[0045] Similarly, the number of clamping slots 200 is set to multiple, and the multiple clamping slots 200 are spaced apart on different side walls of the loading plate 100. The number and position of the clamping cylinders 12 match the clamping slots 200, so that multiple clamping cylinders 12 can simultaneously clamp multiple edges of the loading plate 100. The clamping slot 200 can be set as a groove structure with a concave circular hole, into which the piston end of the clamping cylinder 12 is inserted to achieve locking. In this embodiment, by locking multiple edges of the loading plate 100, a better fixing effect can be achieved.

[0046] In this application, the feeding bracket 1 has a first preset height, such that the feeding limiting groove 11 can simultaneously accommodate at least a plurality of stacked feeding plates 100. The recycling bracket 2 has a second preset height, such that the recycling limiting groove 21 can simultaneously accommodate at least a plurality of stacked feeding plates 100, and the first preset height and the second preset height are equal. Therefore, a corresponding number of feeding plates 100 to be fed can be completely collected by the recycling limiting groove 21 in the recycling bracket 2. This avoids the feeding plates 100 having nowhere to be placed while minimizing the overall height and volume of the structure, and ensuring that the height of structural components such as the support columns is equal, resulting in low production costs.

[0049] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
