Description

Take and place thin plate device

technical field

The utility model relates to a pick-and-place thin plate device, especially a device that uses a rotating and swinging suction device to pick and place thin plates, so as to improve the work of picking and placing substrates and the production efficiency of the production line, and use the bearing seat to allow the substrate to be evenly stressed to avoid excessive The situation where a substrate is crushed by gravity due to stacking occurs.

Background technique

With the advancement of science and technology, the display of vacuum tubes is gradually being eliminated. From large-scale displays such as desktop monitors to displays of portable terminals, LCD panels are used. Therefore, LCD panels must achieve high brightness, low power consumption, and high precision. Requirements, and the key point is the application of polarizing plates. Since polarizing plates were invented in the United States in 1929, due to their wide range of applications (such as microscopes, pilot lenses, and sunglasses), after 1937, polarizing The large-scale production of the polarizers has begun to achieve the goal of commercialization. However, after the front-end production process of the polarizers is completed, a layer of release film will be pasted on the surface to protect the integrity of the polarizer surface and reduce scratches caused by collisions or stacking. Injury or crushing, and improve product yield, so manufacturers invest a lot of manpower and money in manufacturing, packaging and shipping, so that the polarizer has a complete and scratch-free surface.

However, today's industry is facing rising labor and environmental protection awareness, rising labor and operating costs, and pressure from labor-intensive to technology-intensive transformation. The industry either relocates the industry or introduces foreign workers to adapt to the rising cost, or starts from the root , apply industrial automation technology or use appliances to improve business quality and reduce costs. Therefore, under the current wave of industrial automation, what manufacturers want to pursue is not only automated production and manufacturing, but also to improve the efficiency of automated production. The existing equipment The action of retracting and unwinding the polarizing plate is too complicated, and the swing arm needs to be moved many times before the polarizing plate can be placed on the production line. Or lay the polarizer flat and stack it on the pallet, and then use the stacker to move the pallet to the designated position, but this method often causes uneven force on the polarizer when the stacker moves the pallet , which in turn causes the polarizing plate to be crushed due to its own gravity, which increases the defect rate of the finished product and increases the number of defective products, which not only increases the manufacturing cost, but also makes transportation very inconvenient.

The designer once filed a TW new patent application on June 30, 2006 with the "Pick and Place Thin Plate Machine", TW Announcement No. M278678, please refer to Figure 11, which is the side view section of the existing pick and place thin plate machine As shown in the figure, it includes a suction device, a working platform and a transmission device. The suction device A is provided with a cantilever A1, and one side of the cantilever A1 is provided with a suction cup device A2 with a plurality of suction cups A21, and the cantilever A1 is on the other side away from the suction cup device A2 A rotating shaft A3 is provided; the working platform B is provided with a rotary drive device B1 connected to the rotating shaft A3 of the suction device A; the transmission device C is arranged on one side of the working platform B, and the transmission device C is provided with a Place the carrier C1 of the substrate D.

However, the "pick and place sheet machine" still has many defects and inconveniences in actual use, such as:

(1) The transmission device C supports a plurality of substrates D on the carrier C1. However, due to the considerable weight of the plurality of substrates D, the transmission device C has a large resistance and is inconvenient to move.

(2) The transmission device C bears a considerable weight due to carrying multiple substrates D. When moving and displacing, the moving roller C2 at the bottom is prone to greater wear and tear when rolling after bearing the weight, shortening the service life of the moving roller C2.

(3) After the suction device A uses the suction cup A21 to repeatedly suck the substrate D, the distance between the suction device A and the bearing seat C1 will increase, and the transmission device C must drive the bearing seat C1 to approach the suction device A, and the suction device A It is necessary to readjust the swinging position of the cantilever A1 so that the suction cup device A2 can pick up the substrate D by the suction cup A21, which will cause trouble and inconvenience in the processing operation, time-consuming and labor-intensive.

Therefore, how to increase the speed of picking and placing the thin plate machine to further improve the production efficiency of the production line, and let the stacker move the pallets so that the force on the polarizer is more even and prevent the polarizer from being damaged due to its own gravity. Crushing, thereby reducing the defect rate of finished products, is the direction that relevant manufacturers and operators in this industry want to study and improve.
