[0016] Beneficial effects

[0017] 1. The present invention uses a first lateral moving component, a second lateral moving component, a first gripping unit, and a second gripping unit. Ultimately, the first gripping unit and the second gripping unit cooperate with each other to fix the injection-molded object and place it on the conveyor. It is convenient to grip and facilitates automatic disassembly. It solves the problem that the existing injection-molded car door side panels are lifted by hooks, but after being lifted by hooks, the operator needs to manually remove them and place them on the conveyor belt, which is complicated, time-consuming and labor-intensive.

[0018] 2. In this invention, the first lateral moving component and the second lateral moving component move along the crossbeam. The first gripping unit and the first gripping unit on the first lateral moving component cooperate with the second gripping unit and the second gripping unit on the second lateral moving component, so that the first gripping unit and the second gripping unit cooperate with each other to fix the injection-molded object and place it on the conveyor frame; while the air extraction component extracts air and adsorbs the door side panel through the air extraction pipe.

[0019] 3. In this invention, when the injection-molded car door side panel is placed in the frame of the placement area of ​​the conveyor belt, the car door side panel compresses the elastic membrane and elastic arc rod, causing the elastic arc rod to bend downwards. This compression increases the air pressure inside the placement chamber of the placement area, pushing the light-emitting element in the movable cavity upwards. This also causes the conductive vertical plate to move upwards, and simultaneously brings the two sides of the conductive vertical plate of the light-emitting element into contact with a pair of conductive fixing plates. Since the top of the conductive spring is electrically connected to the light-emitting element through the conductive horizontal plate, the light-emitting element is connected in parallel with the air pump. The side wall of the light-emitting element is provided with conductive vertical plates connecting to the conductive horizontal plate. One conductive fixing plate is connected to one pole of the power supply, and the other conductive fixing plate is connected to the other pole of the power supply. The parallel-connected light-emitting elements are directly energized with the vacuum pump. When energized, the light-emitting elements generate colored light, which shines upward through the translucent glass. Simultaneously, the vacuum pump draws air, causing the door side panel to adhere to the bowl-shaped suction structure. When the door side panel is removed, the compressed gas and excess gas drawn in by the vacuum pump are released through a constant pressure valve. The image capturing unit then captures images of the door side panel in the unpressed placement area. When the door side panel is pressed against the frame, it slides down the rigid part. The image capturing unit identifies the door side panel and notifies the operator to remove it. Door side panels correctly placed in the placement area will not trigger an alarm from the image capturing unit, facilitating subsequent removal via the automatic material handling structure.

[0029] Example 1

[0030] The technical solution adopted in this invention is as follows:

[0031] As shown in Figures 1, 2, 3, 4, and 5, this invention discloses an automatic material handling device for injection-molded car door side panels, comprising: a frame 1, a conveying device 2 mounted on one side of the frame, the conveying device including a conveyor frame 3, a first driving assembly 4 disposed within the conveyor frame, a conveyor belt 5 mounted on the outer surface of the conveyor frame, the first driving assembly driving the conveyor belt to rotate, a transfer device 6 mounted on the upper part of the frame, the transfer device including a fixing frame 7, a crossbeam 8 mounted on the fixing frame, and an image capturing unit 9 mounted on the crossbeam. A first lateral moving assembly 10 and a second lateral moving assembly 11 are mounted on the crossbeam. A first gripping unit 12 is mounted on the first lateral moving assembly; a second gripping unit 13 is mounted on the second lateral moving assembly. The first gripping unit and the second gripping unit cooperate to fix the injection-molded object and place it on the conveyor frame.

[0032] The first gripping unit includes a first vertical moving component 14, which includes a side frame 15. A main fixing block 16 is provided within the frame. A connecting rod 17 is mounted at the end of the main fixing block. A side plate 18 is mounted on the connecting rod. A side rod 19 is mounted on the side plate. An air extraction assembly 40 is mounted on the side rod. An air extraction pipe 20 is provided on the air extraction assembly, and an adsorption bowl 21 is provided at the end of the air extraction pipe. The second gripping unit includes a second vertical moving component 22, and a positioning block 23 is provided at the bottom of the second vertical moving component.

[0033] The conveyor belt surface has multiple placement areas 24, with frame bodies 25 forming the edges of each placement area. Each placement area contains a placement chamber 26, with an elastic membrane 27 at the center of its top, the top of which is higher than the rigid portion. An inclined rigid portion 28, higher in the middle and lower on the outside, is located on the outer side of the elastic membrane. A pair of bowl-shaped adsorption structures 29 are provided on the elastic membrane, with a vacuum pump 30 at the bottom of each structure. An elastic arc rod 31 is located on the outer side of each bowl-shaped adsorption structure, its bottom abutting against the bottom surface of the placement chamber. A translucent glass component 32 is located within the frame.

[0034] Both sides of the placement area are provided with movable cavities 33 located below the frame. The movable cavities are connected to the placement chamber through air guide holes 34. The movable cavities are provided with light-emitting elements 35. When the light-emitting elements are powered on, they generate colored light. A pair of conductive springs 36 are provided at the bottom of the light-emitting elements. The bottom of the conductive springs is connected to the two terminals of the air pump through wires.

[0035] The top of the conductive spring is electrically connected to the light-emitting element via a conductive cross plate 37, so that the light-emitting element is connected in parallel with the air pump. The side wall of the light-emitting element is provided with a conductive vertical plate 38 connecting the conductive cross plate. Conductive fixing plates 39 are provided on the side walls of the movable cavity. A pair of conductive fixing plates are connected in series with the contact feet of the light-emitting element. One conductive fixing plate is connected to one pole of the power supply, and the other conductive fixing plate is connected to the other pole of the power supply. The elastic arc rod is a hollow tube with a through hole 42. A constant pressure valve 41 is provided at the top of the tube.

[0036] In this embodiment, the first lateral moving component and the second lateral moving component move along the crossbeam. The first gripping unit and the first gripping unit on the first lateral moving component cooperate with the second gripping unit and the second gripping unit on the second lateral moving component, so that the first gripping unit and the second gripping unit cooperate with each other to fix the injection-molded object and place it on the conveyor frame; while the air extraction component extracts air and adsorbs the door side panel through the air extraction pipe.

[0037] When the injection-molded door side panel is placed in the frame of the conveyor belt's placement area, the door side panel compresses the elastic membrane and elastic arc rod, causing the elastic arc rod to bend downwards. This compression increases the air pressure inside the placement chamber, pushing the light-emitting element in the movable cavity upwards. This also causes the conductive vertical plate to move upwards, bringing the two sides of the conductive vertical plate of the light-emitting element into contact with a pair of conductive fixing plates simultaneously. Because the top of the conductive spring is electrically connected to the light-emitting element through the conductive horizontal plate, the light-emitting element is connected in parallel with the vacuum pump. The side wall of the light-emitting element has conductive vertical plates connecting to the conductive horizontal plate. One conductive fixing plate is connected to one pole of the power supply, and the other conductive fixing plate is connected to the other pole of the power supply, allowing the parallel-connected light-emitting element to... The vacuum pump is directly powered on, at which point the light-emitting element is powered on and generates colored light, which shines upward through the translucent glass. At the same time, the vacuum pump draws air, causing the door side panel to adhere to the bowl-shaped suction structure. When the door side panel is removed, the compressed gas and the excess gas drawn in by the vacuum pump are released through the constant pressure valve. The image capturing unit then captures images of the door side panel in the unpressed placement area. When the door side panel is pressed against the frame, it will slide down along the rigid part. The image capturing unit will identify the door side panel and notify the operator to remove it. Door side panels that are correctly placed in the placement area will not trigger an alarm from the image capturing unit, making it convenient to remove them in subsequent operations via the automatic material handling structure, thus improving the overall automation level of the equipment.

[0038] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
