DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 5 As shown, a preferred embodiment of the utility model proposes a parallel light source and suction cup combination structure, which mainly includes suction cup fixing plate 1, light source plate 8, light-transmitting diffraction plate 9, glass cover plate 2, nozzle seat 3, suction cup 5, electric slip ring 6 and other components, wherein a mounting cavity 101 is provided on the suction cup fixing plate 1, and the mounting cavity 101 is divided into upper and lower layers of cavities, the upper layer is large, and the lower layer is pinned, which are the first cavity and the second cavity respectively. The size of the first cavity is basically the same as that of the light source plate 8, and the size of the second cavity is basically the same as that of the light-transmitting diffraction plate 9. The light source plate 8 is fixed in the first cavity, and the light-transmitting diffraction plate 9 is fixed in the second cavity by screws. The light-transmitting diffraction plate 9 is larger than the light source plate 8 and can completely cover the light source plate 8.

[0025] The light source board 8 is an LED light board, which is composed of small LED lamp beads arranged in a row to provide range lighting; the function of the light-transmitting diffraction plate 9 is to diffract the light transmitted by the LED light board into uniform parallel light, so as to clearly illuminate the outer contour of the product.

[0026] like Figure 5 As shown, a stepped positioning protrusion 102 is formed in the middle area of ​​the mounting cavity 101 and a through hole extending from top to bottom is provided in the middle of the light source plate 8 and the light-transmitting diffraction plate 9. The positioning protrusion passes through the through hole in the middle of the light source plate 8 and the light-transmitting diffraction plate 9 in sequence to position and fix the light source plate 8 and the light-transmitting diffraction plate 9.

[0027] refer to Figure 5 There is also a through hole penetrating the positioning protrusion 102 in the middle of the suction cup fixing plate 1, and the nozzle seat 3 is installed and fixed in the through hole in the middle of the suction cup fixing plate 1, and the electric slip ring 6 is arranged below the suction nozzle seat 3. There is an opening 1021 connected to the first cavity on the side of the positioning protrusion 102, and the contact piece of the light source board 8 is electrically connected to the electric slip ring 6 through the opening 1021. That is to say, no matter how the suction cup fixing plate 1 rotates, the electric slip ring 6 can stably connect to the light source board 8 and supply power to it.

[0028] refer to Figure 2 , Figure 3A slip ring fixing ring 7 is arranged at the bottom of the suction cup fixing plate 1. The electric slip ring 6 is slidably connected to the slip ring fixing ring 7. When the suction cup fixing plate 1 rotates, the electric slip ring 6 does not rotate. The electric ring can realize rotatable sliding contact power supply, and a rotating mechanism is used to supply power to avoid line entanglement and distortion.

[0029] The glass cover plate 2 is fixed on the suction cup fixing plate 1 by screws to seal the mounting cavity 101. The glass cover plate 2 is used to protect the diffraction plate and is very easy to clean. A through hole is provided in the middle of the glass cover plate 2, and the upper end of the suction nozzle seat 3 extends out from the top of the glass cover plate 2 through the through hole.

[0030] refer to Figure 4 A connecting portion 31 is provided at the upper end of the nozzle holder 3 and the lower end of the suction cup 5. The two connecting portions 31 are butted against each other and fixed by a clamp 4. A positioning block 311 is formed at the end of each connecting portion 31 extending radially outward, and a conical surface 3111 is formed at the connection between the positioning block 311 and the connecting portion 31, so that the overall shape of the positioning block 311 is a combination of a cylinder and a truncated cone.

[0031] refer to Figure 6 The clamp 4 is composed of two semicircular rings, and the two ends of the two semicircular rings are connected by bolts. A positioning groove 401 that matches the shape of the positioning block 311 is formed on the inner circumference of the two semicircular rings. When the connection parts 31 of the nozzle holder 3 and the suction cup 5 are docked, the two connection parts 31 are held by the clamp 4, and the positioning block 311 is embedded in the positioning groove 401. Then the clamp 4 is locked. Under the action of the conical surface 3111 on the positioning block 311, the nozzle holder 3 and the suction cup 5 are automatically aligned, so that the centers of the nozzle holder 3 and the suction cup 5 coincide. The tighter the clamp 4 is locked, the more securely the nozzle holder 3 and the suction cup 5 are fixed.

[0032] There is also a through hole between the nozzle seat 3 and the suction cup 5. The upper end surface of the suction cup 5 is the surface in contact with the product, and the contact surface is a smooth surface. A quick-connect connector 10 is arranged in the through hole of the nozzle seat 3. The upper end of the quick-connect connector 10 is fixedly connected to the inner side of the nozzle seat 3. The lower end of the quick-connect connector 10 is used to quickly connect to the external air circuit. The external air circuit will pass through the through hole in the middle of the electric slip ring 6, and extend into the through hole in the middle of the nozzle seat 3, and connect with the quick-connect connector 10. The quick-connect connector 10 can be quickly connected to the air circuit.

[0033] The suction cup 5 is connected to the vacuum generator through an air path. When the suction cup 5 contacts the sucked object, negative pressure is generated inside the suction cup 5 . The pressure inside the suction cup 5 is reduced, forming an atmospheric pressure difference, and fixing the sucked object on the suction cup 5 .

[0034] The upper outlet of the suction cup 5 has various shapes, and the suction cup 5 can be replaced according to different products. In this way, the suction cup 5 can be removed by simply loosening the clamp 4 and then quickly installed.

[0035] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
