Description

Technical Field

[0001] This utility model relates to the field of light guide plate packaging technology, and in particular to a packaging fixture for a printed light guide plate. Background Technology

[0002] Currently, for small and medium-sized light guide plates, stacking 20 pieces before inner packaging is done by a single person. First, the PE film used for packaging is folded and sealed on its own side. Then, the 20 pieces are manually moved and rotated 180 degrees before the opposite side is handled. For large-sized light guide plates (such as 32-inch plates), stacking 10 pieces before inner packaging usually requires two people to stand on opposite sides of the packaging platform and fold and seal the PE film on both sides.

[0003] Considering the processing cost of the product, labor cost is one of the biggest factors. The two-person operation method for large-size light guide plates is outdated. If a single person is to operate the inner packaging operation, 10 pieces need to be manually moved and rotated 180 degrees before the opposite edge can be folded and sealed. In the process of moving and rotating the product, not only are high requirements placed on the strength of the manual laborer, but there is also a risk of damaging the product. Small and medium-sized light guide plates also have this risk of damage during the moving and rotating process.

[0004] It is evident that the two-person packaging method increases labor costs, while the current single-person packaging method can no longer meet the efficiency requirements, reducing packaging efficiency and increasing processing costs.

[0005] To address these issues, we developed a packaging fixture for printed light guide plates. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art by providing a packaging fixture for a printed light guide plate, which has the advantages of easy adjustment, improved efficiency, prevention of scratches, convenient rotation packaging, and intuitive visualization.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a packaging fixture for a printed light guide plate, comprising a lower bakelite board, an upper bakelite board, a rotating shaft, and a connector. A load-bearing spring is pressed onto the rotating shaft at a position between the upper bakelite board and the lower bakelite board. The top end of the load-bearing spring abuts against a first stop plate. The top end of the first stop plate abuts against a gasket via a support member. The gasket abuts against the bottom end of the upper bakelite board. The rotating shaft is rotatably connected to the lower bakelite board. The connector is inserted into the upper bakelite board. The rotating shaft and the connector are adjustablely connected.

[0008] Preferably, the bottom of the connector is provided with a first connector, the side wall of the first connector is provided with a plurality of vertically arranged first insertion holes, the top of the rotating shaft is provided with a blind hole, the side wall of the blind hole is provided with a second insertion hole, and the first insertion hole and the second insertion hole are connected by a pin.

[0009] Preferably, the upper bakelite board has a insertion hole at its center, and the connector has a second connector at its top end, which is inserted into the insertion hole.

[0010] Preferably, an annular groove is provided at the middle position of the rotating shaft, and a second baffle is engaged in the annular groove, the second baffle abutting against the bottom end of the load-bearing spring.

[0011] Preferably, the lower bakelite board is provided with a third baffle on one side of the rotating shaft, and the second baffle and the third baffle are rotatably abutted against each other.

[0012] Preferably, a through hole is provided at the center of the lower bakelite board, and a bearing is pressed into the through hole, and the bearing is rotatably connected to the rotating shaft.

[0013] Preferably, a shoulder is provided at the bottom end of the rotating shaft, and the shoulder abuts against the bearing.

[0014] Preferably, a scale is provided at the middle position of the rotating shaft, and the scale is located at the load-bearing spring.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] The packaging fixture for the printed light guide plate described in this utility model features an axially adjustable shaft and connector, facilitating packaging for different heights and improving convenience. The second baffle rotates with the shaft, while the third baffle restricts the upper bakelite board to rotate 180 degrees in one direction, facilitating folded packaging of the light guide plate on both sides of the top of the upper bakelite board, improving packaging efficiency, and preventing product scratches. The weight-bearing spring and scale settings allow for intuitive judgment of whether the number of light guide plates packaged is insufficient or excessive. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Figures 1 to 3 A packaging fixture for a printed light guide plate includes a lower bakelite board 10, an upper bakelite board 20, a rotating shaft 50, and a connector 30. A load-bearing spring 40 is pressed onto the rotating shaft 50 between the upper bakelite board 20 and the lower bakelite board 10. The load-bearing spring 40 passes through the rotating shaft, and its top end abuts against a first stop plate 60. The top end of the first stop plate 60 abuts against a gasket 69 via a support member 29. The gasket 69 abuts against the bottom end of the upper bakelite board 20. The rotating shaft 50 is rotatably connected to the lower bakelite board 10, and the connector 30 is inserted into the upper bakelite board 20. The rotating shaft 50 and the connector 30 are adjustablely connected. The lower bakelite board 10 can be mounted on the top of a movable chassis or have rollers at its bottom for easy overall movement.

[0022] A through hole 11 is provided at the center of the lower bakelite board 10, and a bearing 12 is pressed into the through hole 11. The bearing 12 is rotatably connected to the rotating shaft 50. The lower bakelite board 10 and the rotating shaft 50 are rotatably connected through the bearing 12. A third baffle 15 is provided on one side of the lower bakelite board 10 at the rotating shaft 50, and a second baffle 65 rotates and abuts against the third baffle 15. The second baffle 65 rotates 180 degrees around the rotating shaft and abuts against the third baffle. The upper bakelite board 20 rotates 180 degrees, and the light guide plate at the top of the upper bakelite board rotates 180 degrees, which facilitates the folding of the two opposite edges of the light guide plate.

[0023] The upper bakelite board 20 has a insertion hole 21 at its center. The connector 30 has a hexagonal head structure, and a second connector 31 is located at the top of the connector 30. The second connector 31 is inserted into the hexagonal insertion hole 21. The bottom of the connector 30 has a first connector 32, and the side wall of the first connector 32 has multiple vertically arranged first insertion holes 33. The top of the pivot 50 has a blind hole 54, and the side wall of the blind hole 54 has a second insertion hole 55. The first insertion holes 33 and the second insertion holes 55 are connected by a pin to adjust the vertical height. The shortest distance from the connector 30 to the top of the insertion hole 21 is greater than the adjustment distance of the pin. A ring groove 52 is provided at the middle position of the rotating shaft 50, and a scale 53 is provided at the middle position of the rotating shaft 50. The scale 53 is located at the load-bearing spring 40, and the compression distance of the load-bearing spring 40 can be visually observed through the scale. The load-bearing spring can support the weight of up to 40 packs of 32-inch products. Each pack of 32-inch products (10 pieces) placed on it can drop approximately 30mm. A second stop plate 65 is engaged with the ring groove 52, and the second stop plate 65 abuts against the bottom end of the load-bearing spring 40. A shoulder 51 is provided at the bottom end of the rotating shaft 50, and the shoulder 51 abuts against the bearing 12. The upper bakelite board 20, the connector 30 and the rotating shaft 50 are integrated into one structure, and the rotating shaft 50 is tumbledly connected to the lower bakelite board 10.

[0024] The freely movable packaging fixture platform consists of an upper and lower bakelite board, a rotating shaft, bearings, and load-bearing springs. The upper bakelite board supports the light guide plate being packaged, and the load-bearing springs compress under pressure. A scale displays the weight of the packaged light guide plates. A single person can operate on the platform, and the height is adjustable to suit the operator's working height. After folding and sealing one side of the light guide plate, the operator rotates the upper bakelite board 180 degrees. A third stop automatically stops the rotating shaft, allowing for folding and sealing of the other side of the light guide plate. After completion, the second package is placed in for inner packaging. When fully loaded (40 packages for 32-inch products, 20 packages for 27-inch and smaller products), the package is directly pushed into the outer packaging area. This eliminates a manual handling and rotation step, avoiding the risk of product damage. Especially in packaging large-sized products, it allows for single-person operation, reducing labor costs and making packaging more effortless for the operator, thus improving packaging efficiency.
