[0022] Reference Figure 1 In an embodiment of the present invention, an automatic loading and unloading processing equipment includes a machine 100, on which a fixture 110, a clamping device 120 and a feeding device are provided, and a fixedly installed workbench 102 is provided on the machine 100, and the fixture 110 is fixedly installed on the workbench 102. The fixture 110 includes a body 111 and a clamping arm 113, the clamping arm 113 is pivotally connected to the body 111, and the clamping arm 113 includes a first end 1131 and a second end 1132. The body 111 is provided with a first elastic member 114, and the first elastic member 114 is used to push against the second end 1132 to rotate the clamping arm 113, so that the first end 1131 presses against the workpiece 101, so as to realize automatic clamping of the workpiece 101, without the need for workers to manually tighten, which is conducive to reducing the labor intensity of workers. The clamping device 120 includes a push block 122, which is pivotally connected to the machine 100. When the push block 122 rotates, it contacts the second end 1132, so that the second end 1132 presses the first elastic member 114 and the first end 1131 is separated from the workpiece 101. The feeding device includes a loading mechanism 130 and a unloading mechanism 150. The loading mechanism 130 is provided with a plurality of clamps 132 for picking up and placing the workpiece 101. The unloading mechanism 150 has a plurality of hooks 152, which are used to contact the bottom wall of the workpiece 101 and can separate the workpiece 101 from the body 111. In the present application, the automatic loading and unloading functions are realized by automatically loading, clamping the workpiece 101, releasing the workpiece 101 and automatically unloading, without the need for workers to manually tighten, which is conducive to reducing the labor intensity of workers, improving production efficiency and improving the yield rate.

[0023] Specifically, refer to Figure 7 , Figure 8 and Fig. 9 The body 111 is provided with a first pivot shaft 117, which is inserted into the clamp arm 113, and the clamp arm 113 rotates about the central axis of the first pivot shaft 117. It can be understood that the first pivot shaft 117 is close to the first end 1131, so that the pivot central axis of the clamp arm 113 is close to the first end 1131, thereby making the pivot central axis of the clamp arm 113 away from the first elastic member 114, that is, by increasing the vertical arm that makes the first elastic member 114 push the clamp arm 113 to rotate, the clamping force of the first end 1131 to clamp the workpiece 101 is increased, and the stability of the clamping is effectively improved.

[0024] It can be understood that the body 111 is provided with a clamping member 116, and the clamping member 116 has a cavity 1161 for accommodating the workpiece 101. When the workpiece 101 is clamped, the inner walls of the cavity 1161 on both sides are pressed against the outer walls of the workpiece 101 on both sides. When the first elastic member 114 pushes the clamping arm 113 to rotate, the first end 1131 of the clamping arm 113 can push the clamping member 116 to deform, thereby clamping the workpiece 101. Specifically, the clamping member 116 includes an elastic portion 1162, and when the first end 1131 pushes the clamping member 116, the elastic portion 1162 can be elastically deformed, and when the first end 1131 leaves the clamping member 116, the elastic portion 1162 can be elastically reset, thereby releasing the workpiece 101. Furthermore, the clamping member 116 is provided with a hollow portion 1163, which is located below the workpiece 101 and communicates with the cavity 1161. The hollow portion 1163 can cause the elastic portion 1162 to produce elastic deformation, thereby clamping and releasing the workpiece 101. It is understandable that the first elastic member 114 is a coil spring.

[0025] Reference Fig.10 and Fig.11 The main body 111 is provided with a plurality of bosses 115, and the bosses 115 are used to support the workpiece 101. Specifically, the bosses 115 are located on the top wall of the clamping member 116, and when the workpiece 101 is placed in the clamping member 116, a plug-in groove 112 is formed between the bottom wall of the workpiece 101 and the top wall of the clamping member 116. Figure 1 and Figure 2 The unloading mechanism 150 is provided with a plurality of pick-up rods 151 arranged at intervals, and a hook 152 is arranged at the end of the pick-up rod 151 and extends in the horizontal direction. When unloading after processing, the hook 152 can be plugged into the plug-in slot 112 in the horizontal direction. When the unloading mechanism 150 rises upward, the hook 152 can contact the bottom wall of the workpiece 101 to lift the workpiece 101, so that the workpiece 101 leaves the fixture 110, and the unloading process is completed.

[0026] Reference Figure 2It can be understood that at least three insertion slots 112 are provided on the clamping member 116. In the present application, the workpiece 101 is supported by three hooks 152 during blanking, and the three hooks 152 are respectively located at both ends and the middle portion of the workpiece 101.

[0027] Reference Figure 3 The clamping device 120 is arranged at the bottom of the workbench 102. The workbench 102 is provided with a plurality of second pivot shafts 123. The second pivot shafts 123 are plugged into the push block 122 and enable it to rotate relative to the workbench 102. It can be understood that the push block 122 includes a pressure contact end 124 and a traction end 125. The clamping device 120 includes a traction cylinder 121. The traction cylinder 121 is an air cylinder. The end of the piston rod of the traction cylinder 121 is hinged to the traction end 125. When the traction cylinder 121 is started and pulls the push block 122, the push block 122 rotates, and the pressure contact end 124 presses the second end 1132 of the clamp arm 113, so that the clamp arm 113 rotates and the first end 1131 leaves the clamping member 116, thereby realizing the clamping process. When the piston rod of the traction cylinder 121 extends, it pushes the traction end 125 and drives the push block 122 to rotate, and the pressure contact end 124 leaves the second end 1132 , so that the clamping arm 113 can be reset under the drive of the first elastic member 114 , thereby clamping the workpiece 101 .

[0028] It can be understood that the second pivot shaft 123 is close to the pressure contact end 124, so that the distance between the pivot center axis of the pushing block 122 and the pressure contact end 124 is smaller than the distance from the traction end 125. The rotational torque can be increased by increasing the vertical arm that drives the pushing block 122 to rotate by the thrust cylinder, so that the pushing block 122 can smoothly drive the clamping arm 113 to rotate, which is beneficial to improving efficiency.

[0029] Reference Figure 4 It is understood that the clamp 132 includes a movable clamp 133 and a fixed clamp 134, and the workpiece 101 is clamped between the movable clamp 133 and the fixed clamp 134, and the fixed clamps 134 of the plurality of clamps 132 are fixed to each other. It is understood that the fixed clamp 134 has a reference surface (not shown in the figure) for pressing the workpiece 101, and the reference surfaces between two adjacent fixed clamps 134 are coplanar, thereby ensuring that the positions of two adjacent workpieces 101 remain consistent when picking up materials, avoiding position errors and thus avoiding material loading failures.

[0030] It is understandable that the feeding device also includes a pressing mechanism 140, and the pressing mechanism 140 is provided with a plurality of pressing blocks 143, and the pressing blocks 143 are used to press the workpiece 101 located in the fixture 110. Specifically, the feeding mechanism 130 is provided with a first base 131, and the pressing mechanism 140 is provided with a second base 141, and the first base 131 and the second base 141 are fixedly connected to each other. It is understandable that the feeding mechanism 130 clamps the workpiece 101 through the clamp 132 and places it on the fixture 110, and the pressing mechanism 140 presses the top wall of the workpiece 101 through the pressing blocks 143 to ensure that the workpiece 101 is fully placed in the cavity 1161, thereby avoiding position errors of the workpiece 101 and thus avoiding processing errors.

[0031] It is understandable that the second base 141 is provided with a second elastic member 142, and the second elastic member 142 is located in the pressing block 143. The second elastic member 142 can keep the pressing block 143 protruding outward, and the pressing block 143 can move relative to the second base 141 when pressing the workpiece 101, so as to avoid hard contact between the pressing block 143 and the workpiece 101, thereby avoiding damage to the workpiece 101. It is understandable that the second elastic member 142 is a coil spring.

[0033] It can be understood that the positioning mechanism is provided with a positioning cylinder 165, the end of the piston rod of the positioning cylinder 165 is connected to the positioning block 164, and at least two positioning blocks 164 are provided in the embodiment of the present application, and the two positioning blocks 164 are located on the opposite side outer walls of the material plate 162. The two positioning cylinders 165 can drive the positioning blocks 164 and clamp them on the two side outer walls of the material plate 162, which is conducive to centering the material plate 162.

[0034] In other embodiments, a plurality of reference blocks 163 are provided on the support plate 161, and the reference blocks 163 are respectively located on the adjacent two side walls of the material sheet 162, and the positioning block 164 can press on the other side outer wall of the material sheet 162 relative to the reference block 163. When the positioning block 164 presses on the outer wall of the material sheet 162, the other outer side wall of the material sheet 162 can press on the reference block 163, thereby fixing the position of the material sheet 162.

[0035] It can be understood that the material storage device 160 is also provided with a lifting mechanism, which includes a support block 166 and a lifting plate 167.

The support block 166 can resist the material plate 162 and lift the material plate 162, so that the material plate 162 can be picked up by a robot to realize automatic replacement of the material plate 162, which is beneficial to improving production efficiency.

[0036] Specifically, refer to Figure 6 The lifting mechanism is arranged at the bottom of the support plate 161. The bottom of the support plate 161 is provided with a lifting cylinder 171. The lifting cylinder 171 is used to drive the lifting plate 167 to move up and down. The support plate 161 has a through-going channel 173. The support block 166 can pass through the support plate 161 from bottom to top through the channel 173 to lift the material plate 162. It can be understood that the lifting plate 167 is also provided with a support rod 172, and the support block 166 is fixedly installed at the end of the support rod 172.

[0037] Reference Figure 5 It is understandable that the material storage device 160 is also provided with a cover plate 168, which is slidably connected to the support plate 161 and is used to cover the material plate 162 to prevent metal debris from falling into the material plate 162 during processing, thereby preventing the debris on the blank workpiece 101 from affecting the stability of the material when taking out the material. Specifically, slide rails 169 are provided on both sides of the support plate 161, and a slider (not shown in the figure) is provided on the cover plate 168. At the same time, a sliding cylinder 170 is also provided.
