Description

Technical Field

[0001] The utility model relates to the technical field of displays, in particular to a filter strip pressing machine. Background Art

[0002] When producing displays, it is often necessary to install filter strips on the display frame. The traditional installation method of the filter strip is to hammer it manually with a rubber hammer, so that the filter strip is pressed into the frame by knocking. This method requires a lot of manpower, and the knocking will also produce a lot of noise. Even the strength and position of the knocking need to be precisely controlled, otherwise the frame and the filter strip will be damaged. The filter strip pressing machine in the prior art is equipped with two sets of upper and lower pressing rollers, which are driven by a driving mechanism to rotate the pressing rollers, and the frame and the filter strip are sent between the two sets of pressing rollers for roller-pressing assembly. In this way, the frame will move, and there is a risk of friction on the side of the frame during the movement of the frame, resulting in damage to the frame surface. In addition, the force-bearing area of ​​the frame is small, especially for the frame of large-sized TVs, which is prone to deformation during the rolling process, thereby reducing the yield rate.

[0003] On the other hand, existing filter strip pressing machines all manually adjust the distance between the two sets of pressing rollers through a screw rod to adjust the pressing force of the filter strip pressing machine. This adjustment method requires relying on the operator's operating experience to adjust. When processing frames of different models, repeated debugging is required, which is inconvenient to use and has low production efficiency. When the appropriate pressing force is not adjusted, the yield rate will be further reduced, and manual re-inspection is required one by one, which reduces production efficiency. Therefore, it is necessary to improve it. Utility Model Content

DETAILED DESCRIPTION

[0032] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0033] A filter strip pressing machine, such as Figures 1 to 5 As shown, it includes a machine 1, and the machine 1 is provided with a clamping device, a pressing device and a sliding device. The sliding device includes a transverse slide rail 71, a transverse driving mechanism and a pulley. The transverse slide rail 71 is provided on the machine 1 and extends in the transverse direction. The pulley is slidably installed on the transverse slide rail 71. The transverse driving mechanism is transmission-connected to the pulley. The pressing device includes a pressing driving mechanism, a pressure sensing mechanism, a pressing frame 4 and at least one rolling wheel 5. The pressing frame 4 is slidably installed on the pulley, and the rolling wheel 5 is rotatably installed on the lower part of the pressing frame 4. The pressing driving mechanism is fixedly installed on the pulley. The pressing driving mechanism is transmission-connected to the pressure sensing mechanism, and the pressure sensing mechanism is transmission-connected to the pressing frame 4.

[0034] The conventional filter strip pressing machine presses the filter strips by rolling, and the movement of the frame easily causes scratches, and the force-bearing area is small, which easily causes the frame and the filter strip to deform, making it difficult to accurately adjust the pressing force and requiring manual re-inspection, resulting in low production efficiency and low yield rate. The utility model drives the pressing device to move laterally through a sliding device, without the need for frame movement, and the pressing device moves laterally to roll the filter strips to complete the pressing, thereby preventing scratches caused by the movement of the frame; the frame is fixed by a clamping device, and the rolling wheel 5 only rolls the filter strips, thereby increasing the force-bearing area of ​​the frame during pressing, preventing the frame from deforming, and improving the yield rate; the pressing drive mechanism drives the rolling wheel 5 to descend for pressing during pressing, and then drives the rolling wheel 5 to reset upward after the pressing is completed, thereby increasing the space for loading and unloading, and facilitating loading and unloading; the pressure sensing mechanism monitors the pressing force in real time, and can accurately adjust the pressing force before pressing, without repeated debugging, making it more convenient to use and improving production efficiency.

[0035] Specifically, the pressure sensing mechanism includes a pressure sensor 61, an upper baffle 62, a lower baffle 63, two limit baffles 64, and two limit adjustment members. The upper baffle 62 is in transmission connection with the pressing drive mechanism, and the lower baffle 63 is fixedly mounted on the pressing frame 4. The pressure sensor 61 is disposed between the upper baffle 62 and the lower baffle 63. The upper ends of the two limit baffles 64 are respectively disposed at the left and right ends of the upper baffle 62. The two limit adjustment members are respectively disposed at the left and right ends of the lower baffle 63. The lower ends of the two limit baffles 64 are respectively engaged with the upper ends of the two limit adjustment members. After pressing, the pressure sensor 61 generates a pressing force variation curve, which can be used to determine whether the pressing is over-pressed or under-pressed based on the pressing force variation curve. Automatic inspection eliminates the need for manual re-inspection, further improving production efficiency and yield rate. When the maximum detection value of the pressure sensor 61 is reached, the limit adjustment member limits the limit baffle 64 to prevent damage to the pressure sensor 61, thereby improving reliability and stability; during pressing, when the pressure sensor 61 reaches the maximum detection value, the horizontal drive mechanism stops working, and the pressing drive mechanism drives the pressing frame 4 to move upward and reset to prevent damage to the filter strip, making it easier for the operator to check for abnormal pressing conditions of the filter strip, make timely adjustments, and reduce losses.

[0036] Specifically, the pressing drive mechanism includes a lifting cylinder 31 and a connector 32. The lifting cylinder 31 is fixedly mounted on the pulley.

Two lifting rails 841 are provided on the front side of the pulley in the vertical direction. The two lifting rails 841 are arranged in parallel and spaced apart. Two lifting sliders 41 are fixedly mounted on the rear side of the pressing frame 4. The two lifting sliders 41 are respectively slidably mounted on the two lifting rails 841. The lifting cylinder 31 is used for driving, and the driving structure is simple and reliable. The lifting cylinder 31 adopts an adjustable stroke cylinder. The pressing force is adjusted by adjusting the driving stroke of the lifting cylinder 31. The pressure sensor 61 is connected through the connector 32, which is convenient for disassembly and maintenance. The lifting rails 841 and the lifting slider 41 are used to reduce the friction between the pressing frame 4 and the pulley, prevent jamming, and improve operational stability.

[0037] Specifically, the limit adjustment member includes a limit screw 651 and a limit nut 652. The lower baffle 63 defines a limit mounting hole 631.

The upper end of the limit screw 651 engages with the limit baffle 64 for a limited position. By rotating the limit screw 651, the height of the limit screw 651 extending from the lower baffle 63 can be adjusted, thereby adapting to different models of pressure sensors 61 and expanding the range of applications.

[0038] Specifically, the trolley includes a sliding base 81, a sliding frame, and an adjustment screw 86.

Rotating the adjustment screw 86 drives the sliding frame to move back and forth on the sliding base 81, thereby facilitating adjustment of the roller wheel 5 to the position above the filter strip.

[0039] Specifically, the transverse drive mechanism includes a rack 72, a gear 73, a reducer 74, and a motor 75. The rack 72 is provided on the machine 1 and extends in the transverse direction. The rack 72 is located between the transverse slide rail 71 and the clamping device. A driving fixed plate 813 is provided at the front of the sliding base 81. The reducer 74 is fixedly mounted on the rear side of the driving fixed plate 813. The output end of the reducer 74 passes through the driving fixed plate 813 and is connected to the gear 73. The gear 73 meshes with the rack 72. The motor 75 is fixedly mounted at the rear of the reducer 74 and is in transmission connection with the reducer 74. After the motor 75 is reduced in speed by the reducer 74, it drives the gear 73 to rotate, thereby driving the pulley to move in the transverse direction. The transverse drive mechanism is installed on the sliding base 81 through the driving fixed plate 813, which does not affect the adjustment of the sliding frame. The drive structure is simple and the cost is low.

[0040] The cam 82 is fixed on the left and right sides of the cam 83 and the left and right sides of the cam 83 are fixed on the right and left sides of the cam 83. The cam 82 is fixed on the left and right sides of the cam 83 and the left and right sides of the cam 83 are fixed on the right and left sides of the cam 83. The reducer 74 and the motor 75 are located in the drive mounting cavity to protect them, reduce the entry of dust and foreign matter, and improve reliability and stability. The limit plate 814 limits the adjustment base plate 82 in the horizontal direction, and the adjustment plate 812 and the drive fixing plate 813 limit the adjustment base plate 82 in the longitudinal direction. The structure is simple and the cost is low.

[0041] Specifically, the clamping device includes two transverse clamping blocks 21, multiple longitudinal clamping blocks 22, and multiple clamping cylinders 23. Each longitudinal clamping block 22 is fixed to the machine 1 at intervals along the transverse direction and is located in front of the sliding device. Each clamping cylinder 23 is fixed to the machine 1 and is located in front of each longitudinal clamping block 22. Each longitudinal clamping block 22 corresponds to each clamping cylinder 23 in the longitudinal direction. A clamping gap is formed between the multiple longitudinal clamping blocks 22 and the multiple clamping cylinders 23. Two transverse clamping blocks 21 are set on the machine 1 and are located on the left and right sides of the clamping gap. The frame is limited and clamped in the longitudinal direction by each clamping cylinder 23 and each longitudinal clamping block 22, and the frame is limited in the transverse direction by the two transverse clamping blocks 21, ensuring that the frame is fixed and does not move during pressing, thereby improving the pressing success rate.

The outer side surface of the rolling rubber ring 53 is provided with an arc-shaped rolling surface 531. The two rotating bearings 51 reduce the rotational friction of the rolling wheel 5, preventing the rolling wheel 5 from getting stuck and causing friction between the rolling wheel 5 and the filter strip, thereby improving reliability and stability. The rolling rubber ring 53 has an interference fit with the filter strip and is made of rubber with a hardness of 40 to 50 degrees. The rolling rubber ring 53 can further prevent scratches on the filter strip and further improve the yield rate. The arc-shaped rolling surface 531 of the rolling rubber ring 53 contacts the filter strip, thereby reducing the contact area with the filter strip, not only reducing the risk of scratches but also increasing the pressure, further improving the installation effect.

[0043] Specifically, safety shields 11 are installed on the left and right sides and rear side of the machine 1, and safety gratings 12 are installed on the left and right ends of the front side of the machine 1. The safety shields 11 enclose the left and right sides and rear side of the machine 1, preventing foreign objects from entering and preventing the filter strips from breaking and popping out during lamination, thereby improving safety. The safety gratings 12 form a warning line on the front side of the machine 1, preventing the operator from crossing the warning line during lamination, further improving safety.
