[0017] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows by combining with the drawings and preferred embodiments.

[0018] EMBODIMENT

[0019] This embodiment provides a loading and unloading device, which includes an upper fixed plate 1, a transfer plate 2, a lower fixed plate 3 and a driving device 4. The upper fixed plate 1 is connected to the lower fixed plate 3, and the upper fixed plate 1 and the lower fixed plate 3 are spaced apart. The transfer plate 2 is arranged between the upper fixed plate 1 and the lower fixed plate 3. The driving device 4 is arranged on the upper fixed plate 1. The driving device 4 drives the transfer plate 2 to move between the upper fixed plate 1 and the lower fixed plate 3. The transfer plate 2 is provided with a vacuum adsorption plate 5 and several first suction cup assemblies 6. The lower fixed plate 3 is respectively provided with through holes corresponding to the vacuum adsorption plate 5 and the first suction cup assembly 6, and the lower fixed plate 3 is provided with several second suction cup assemblies 7.

[0020] like Figures 1 to 3 As shown, the figure schematically illustrates an embodiment. Four connecting rods 8 are disposed between the upper fixing plate 1 and the lower fixing plate 3. The four connecting rods 8 are located at the four corners of the upper fixing plate 1 or the lower fixing plate 3. The ends of the connecting rods 8 are connected to the upper fixing plate 1 and the lower fixing plate 3, respectively. Of course, the above is only a preferred embodiment, and the number of connecting rods 8 is not limited to four. The specific number can be set as needed.

[0021] The transfer plate 2 is arranged on the connecting rod 8, and the transfer plate 2 can be driven to slide on the connecting rod 8. Figure 1 In the preferred embodiment shown, the transfer plate 2 has a first sliding hole, and a first linear bearing 9 is provided at the first sliding hole. The first linear bearing 9 is installed in conjunction with the connecting rod 8. Specifically, the first linear bearing 9 is preferably a straight-cylinder linear bearing, which is passed through the first sliding hole. The two ends of the straight-cylinder linear bearing are fixedly installed in the first sliding hole through retaining rings. Figure 1 In the embodiment shown, since the transfer plate 2 is relatively thin, a collar 14 is additionally installed when fixing the straight-cylindrical linear bearing.

[0022] The transfer plate 2 is provided with a second sliding hole, and a second linear bearing 10 is provided at the second sliding hole. The second linear bearing 10 is preferably a flange type linear bearing, which is fixedly connected to the transfer plate 2 through its flange portion. Figure 1The second linear bearing 10 is provided with a sliding rod 11, one end of the sliding rod 11 is connected with the vacuum adsorption plate 5, the other end of the sliding rod 11 passes through the second linear bearing 10 and is provided with a stopper 12. The stopper 12 is fixedly connected with the sliding rod 11, and the size of the stopper 12 is greater than the bearing hole of the second linear bearing 10, thereby preventing the sliding rod 11 from being separated from the second linear bearing 10. The sliding rod 11 is provided with a spring member 13, the spring member 13 is located between the second linear bearing 10 and the vacuum adsorption plate 5, and the two ends of the spring member 13 are respectively abutted with the second linear bearing 10 and the vacuum adsorption plate 5. In this way, when the transfer plate 2 falls and the vacuum adsorption plate 5 collides with the product to be adsorbed, the spring member 13 is deformed under stress, and the vacuum adsorption plate 5 can be in flexible contact with the product to be adsorbed, thereby avoiding damage to the product.

[0023] In further embodiments, the first suction cup assembly 6 is located at the periphery of the vacuum adsorption plate 5. Preferably, a plurality of first suction cup assemblies 6 are symmetrically arranged on both sides of the vacuum adsorption plate 5. For example Figure 1 or Figure 2 As shown schematically in the middle, the transfer plate 2 is provided with a fixed lug 15 on both sides of the outer edge, the fixed lug 15 is provided with two first fixing holes, and the first suction cup assembly 6 is installed in the first fixing hole. Specifically, the first suction cup assembly 6 includes a first suction cup connecting rod 61 and a first suction cup 62, the first suction cup connecting rod 61 is provided in the first fixing hole and is fixedly connected with the fixed lug 15. The first suction cup connecting rod 61 corresponds to the through hole of the lower fixed plate 3, and the lower end extends towards the corresponding through hole. The first suction cup 62 is arranged at the lower end of the first suction cup connecting rod 61 and located in the corresponding through hole, and the acting end of the first suction cup 62 faces downward, as Figure 3 The acting surface of the vacuum adsorption plate 5 faces downward. Since the vacuum adsorption plate 5 and the first suction cup assembly 6 can adopt a conventional structure, the specific structure and working principle thereof will not be described in detail in this embodiment.

[0024] In further embodiments, the second suction cup assembly 7 is located at the periphery of the vacuum adsorption plate 5. Preferably, the inner edge of the lower fixed plate 3 extends inwardly to form a fixed lug structure 31, the fixed lug structure 31 is provided with a second fixing hole, and the second suction cup assembly 7 is installed in the second fixing hole, as Figure 3As shown. Specifically, the second suction cup assembly 7 includes a second suction cup connecting rod 71 and a second suction cup 72. The second suction cup connecting rod 71 is inserted into the second fixing hole and fixedly connected to the fixing ear structure 31. The second suction cup 72 is disposed at the lower end of the second suction cup connecting rod 71, with the active end of the second suction cup 72 facing downward. Since the second suction cup assembly 7 can adopt a conventional structure, its specific structure and working principle will not be described in detail in this embodiment.

[0025] In a preferred embodiment, the driving device 4 is an electric cylinder, the body 41 of the electric cylinder is fixed to the upper fixed plate 1, and the driving block 42 of the electric cylinder is fixedly connected to the transfer plate 2. Figures 1 to 3 As shown. Guided by the connecting rod 8, the electric cylinder drives the transfer plate 2 to move up and down between the upper fixed plate 1 and the lower fixed plate 3, thereby driving the first suction cup assembly 6 and the vacuum adsorption plate 5 to move up and down relative to the lower fixed plate 3. In a specific implementation, the upper fixed plate 1 can be connected to an external robot, which can then drive the entire loading and unloading device.

[0026] Next, combine Figures 3 to 5 The working process of the loading and unloading device of this embodiment is briefly described.

[0027] When the outer frame and the black film need to be sucked, the driving device 4 drives the transfer plate 2 to drive the vacuum adsorption plate 5 and the first suction cup assembly 6 to move downward, and the vacuum adsorption plate 5 and the first suction cup assembly 6 pass through the lower fixed plate 3 through the corresponding through holes. Figure 3 or Figure 4 Driven by an external robot, the loading and unloading device moves to the corresponding adsorption position, the first suction cup assembly 6 adsorbs the outer frame, and the vacuum adsorption plate 5 adsorbs the black film.

[0028] When it is necessary to absorb the chip substrate, the driving device 4 drives the transfer plate 2 to drive the vacuum adsorption plate 5 and the first suction cup assembly 6 to move upward and retract to the lower fixed plate 3. Figure 5 Driven by an external robot, the loading and unloading device moves to the corresponding adsorption position, and the second suction cup assembly 7 adsorbs the chip substrate.

[0029] When the black film is attached to the chip substrate, the driving device 4 drives the transfer plate 2 to move the vacuum adsorption plate 5 downward. Driven by an external robot, the chip substrate with the black film attached is placed at a designated position through the vacuum adsorption plate 5.

[0030] The feeding and discharging device of the application can improve discharging efficiency, improve production efficiency and reduce labor cost; and has a clever structure design, which can suck two kinds of products of outer frame and black film and chip substrate.
