[0030] The specific embodiments described herein are merely illustrative of the technical solutions of this patent and are not intended to limit the scope of the disclosed technical solutions. It should also be noted that, for ease of description, the accompanying drawings show only the parts relevant to the technical solutions of this disclosure, and not the entire structure.

[0031] Before discussing the exemplary embodiments in more detail, it should be mentioned that the structure of the device components and / or modules mentioned in the embodiments, unless otherwise described in detail, is something that can be understood by those skilled in the art based on existing public technologies or is a commercially available product.

[0032] refer to Figure 2 and 3 The end plate loading device provided in this embodiment includes a material rack 1, a lifting plate 2, a lifting machine 3, a guide shaft 4, a connecting plate 5, and a discharge mechanism 6. The material rack 1 is a multi-layer double slide rail arranged side by side for storing end plates layer by layer. The lifting plate 2 is horizontally arranged at the moving end of the lifting machine 3, and the material rack 1 is arranged on the lifting plate 2. The guide shafts 4 are respectively arranged on the side of the material rack 1, and at least one guide shaft 4 passes through the lifting plate 2. The connecting plate 5 is horizontally connected to the top end of the guide shaft 4. The discharge mechanism 6 is arranged in front of the material rack 1 and is an automatic pull rod with a guide groove for carrying the end plates out of the material rack 1.

[0033] The material rack 1 can consist of a left side plate, a right side plate, and multiple pairs of sliding grooves. Each pair of sliding grooves is arranged horizontally in layers on the inner walls of the left and right side plates. The distance between a pair of sliding grooves on the same plane is adapted to the size of the end plate. That is, the spacing between adjacent sliding grooves on the left and right sides is adapted to the planar dimensions of the end plate, and the spacing between adjacent sliding grooves on the top and bottom is adapted to the thickness of the end plate. Generally, a material rack has more than 10 pairs of sliding grooves and can hold at least 10 end plates. Preferably, both the left and right side plates have vertical folded edges at the rear to prevent the end plates from moving backward.

[0034] Preferably, a vertical baffle 7 is provided in front of the material rack 1. The upper edge of the baffle 7 is fixed to the connecting plate 5, and the lower edge of the baffle 7 is at the same height as the second-to-last sliding groove of the material rack 1, so as to ensure that the material mechanism 6 pulls out one end plate each time.

[0035] Preferably, a movable plate 8 is provided below the connecting plate 5 and at the top of the material rack 1. The movable plate 8 is connected to the guide shaft 4 through a linear bearing to further enhance the safety of the workpieces on the material rack.

[0036] Preferably, a support frame 9 is provided in addition, and the discharge mechanism 6 is fixed on the support frame 9.

[0037] Preferably, a base platform 10 is provided, and a perimeter fence 11 is provided on the left, right and rear sides of the base platform 10. The support frame 9 and the guide shaft 4 are both provided on the base platform 10, which facilitates the overall adjustment of position and relocation.

[0038] Preferably, a screw jack is used. Recommended configuration: 750W servo motor, 2.5t load capacity, 650mm effective stroke, speed ratio 24.

[0039] refer to Figure 3 and Figure 4 This embodiment provides a discharge mechanism 6, which includes two guide grooves 601, a pull rod 602, a rodless cylinder 603, a positioning cylinder 604, and an ejection cylinder 605. The pull rod 602 is connected to the slider of the rodless cylinder 603. The guide grooves 601 are located above the pull rod 602, and the positioning cylinder 604 is located outside the guide grooves 601. The ejection cylinder 605 is located at the front end of the rodless cylinder 603 and is used for buffer positioning. The discharge mechanism 6 is fixed by multiple support columns 606, which support the two guide grooves 601 above the pull rod 602. The rodless cylinder 603 can be of model SMC MY1B40-700Z-M9B, etc., and the positioning cylinder 604 can be of model Airtac TCL25*70S, etc.

[0040] During operation, the rodless cylinder 603 drives the pull rod 602 to pull the end plate out along the guide groove 601. After the end plate is pulled out, the positioning cylinder 604 performs secondary positioning on the end plate to facilitate subsequent handling and transfer by the robot.

[0041] Preferably, a detection sensor is installed on the top of the material rack 1, which can automatically issue an alarm signal to prompt material feeding when there is no end plate.

[0042] refer to Figure 1 The end plates are manually loaded into both racks of the end plate loading device of this utility model. The discharge mechanism 6 carries the end plate at the bottom of the rack out and moves it along the slide 601 to the middle of the handling robot's gripping position. Then the handling robot delivers the end plate to the welding position of the column.

[0043] After the end plate is removed, the feeding device retracts the discharge mechanism, and then the material rack descends one chute position, where the discharge mechanism pulls out another end plate. This process automatically and sequentially pulls out all the end plates in the material rack. If the detection sensor above does not detect an end plate, it issues an alarm signal, prompting the material rack to be reloaded.

[0044] The above are illustrative examples of preferred embodiments of the present invention. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
