[0032] like Figure 1 and Figure 2 As shown, a preferred embodiment of the present invention provides an automatic LCD strip receiving device, which includes a base 1 for supporting various mechanisms of the automatic LCD strip receiving device.

[0033] The base 1 is provided with a feeding mechanism 2, a turnover mechanism 3, a first transfer mechanism 4, a material collecting mechanism 5, a second transfer mechanism 6 and a rack pre-storing mechanism 7. The feeding mechanism 2 extends from outside the base 1 to the base 1 and is used to transport LCD elements into the base 1. Specifically, the feeding mechanism 2 includes a conveying belt arranged horizontally, and the produced LCD elements are continuously conveyed into the material collecting mechanism 5 by the conveying belt. The turnover mechanism 3 is arranged on one side of the feeding mechanism 2 and includes a first fixing device 31 for clamping the LCD element and a rotating device 32 connected to the first fixing device 31. Since the conveying belt conveys the horizontally placed LCD elements, the turnover mechanism 3 is needed to turn the LCD elements into a vertical state, so as to facilitate the final vertical insertion of the LCD elements into the tray. The first transfer mechanism 4 is arranged above the feeding mechanism 2 and the turnover mechanism 3 and includes a first sliding rail 41 and a first suction device 42 slidingly connected to the first sliding rail 41. The first suction device 42 is used to transport the horizontally placed LCD elements from the feeding mechanism 2 to the turnover mechanism 3, and then turn the LCD elements by the turnover mechanism 3. The turnover mechanism further includes an LCD positioning mechanism for guiding the first suction device 42 to accurately place the LCD element in the first fixing device 31. The first suction device 42 is further connected to a first rotating device. The first rotating device can drive the first suction device 42 to rotate axially, so that the clamped LCD element matches the direction of the rack gear of the rack, and the LCD element can be accurately inserted into the rack gear.

[0034] The material collecting mechanism 5 is arranged on one side of the turnover mechanism 3 and includes a rack bearing platform and a moving device. The rack bearing platform is provided with a positioning device and a rack clamping device. The positioning device facilitates the third transfer mechanism to accurately place the rack on the rack bearing platform. The rack clamping device fixes the rack placed on the rack bearing platform firmly, so that the rack does not move relatively during the movement of the moving device. The rack bearing platform is installed on the moving device to bear the rack and receive the LCD element. The rack bearing platform can move according to the preset program with the moving device. The moving device includes a third sliding rail 51 and a sliding block 52 slidingly connected to the third sliding rail 51.

The second transfer mechanism 6 is arranged above the turnover mechanism 3 and the material collecting mechanism 5 and includes a second sliding rail 61 and a second clamping jaw 62 slidingly connected to the second sliding rail 61.

The material rack pre-storing mechanism 7 comprises a material rack positioning device and a material rack detecting device. The material rack is detected at the material rack pre-storing mechanism 7 before being placed in the material collecting mechanism 5. The material rack positioning device ensures that the material rack is placed accurately at the material rack pre-storing mechanism 7, so as to facilitate the photoelectric detection of the receiving position of the LCD element of the material rack by the material rack detecting device, prevent the interference between the LCD element and the rack gear in the subsequent material collecting process, and cause damage to the LCD element. The third transfer mechanism 8 transfers the material rack from the material rack pre-storing mechanism 7 to the material collecting mechanism 5 after the detection is completed.

[0036] In the working process of the LCD strip rack automatic material collecting device, the feeding mechanism 2 sends the horizontally placed LCD element from the outside to the inside of the material collecting device. After the first suction device 42 of the first transfer mechanism 4 takes the LCD element at the feeding mechanism 2, the first rotating device rotates the orientation of the LCD element, and then transfers the LCD element to the turnover mechanism 3. The turnover mechanism 3 fixes the horizontal LCD element through the first fixing device 31, and then rotates the LCD element through the turnover device to make it in a vertical state, so as to facilitate the second transfer mechanism 6 to take out the LCD element in the turnover mechanism 3 and insert it into the material rack. The material rack is placed on the material collecting device, and is placed on the material rack bearing platform after being detected by the material rack pre-storing mechanism 7. After the second transfer mechanism 6 places a piece of LCD element on the material rack, the moving device moves to adjust the placement position of the LCD element on the material rack, so that the material rack completes the collection of the LCD element. The LCD strip rack automatic material collecting device of the LCD element realizes the full-process automation of material flow, eliminates the beat fluctuation caused by manual operation, and ensures the continuous and stable operation of the production line. The grabbing mechanism replaces manual transportation, eliminates the surface scratches and static damage caused by manual transportation, improves the product quality, greatly reduces the labor cost, and reduces the production capacity fluctuation caused by personnel efficiency problems.
