Description

Technical Field

[0001] The present invention belongs to the field of display panel testing, and in particular relates to a manual buckle opening device and method. Background Art

[0002] With the rapid development of display panels and the improvement of people's living standards, display panels are used more and more widely in daily life. In order to effectively ensure the quality of display panels, technicians will perform a series of performance tests on them during the production process of their display panels.

[0003] In related technologies, display panels need to undergo performance testing at different workstations before leaving the factory. To facilitate transport between different workstations, existing display panels are usually placed on a carrier plate to form an integrated loading unit. The carrier plate is then transported to load the display panels to different workstations. The carrier plate is equipped with a rotatable clip, and an elastic member (torsion spring or spring) is sandwiched between the clip and the carrier plate to ensure that the display panel is securely clamped to the carrier plate.

[0004] However, when placing the display panel on the carrier, it is necessary to manually overcome the elastic force of the elastic member to continuously press the buckle so that the buckle opens and remains open until the display panel is placed in place. Moreover, the buckle is very easy to slip out during the pressing process, resulting in low production efficiency. Summary of the Invention

[0005] In response to the above defects or improvement needs of the prior art, the present invention provides a manual buckle opening device and method, the purpose of which is to achieve continuous pressing of the buckle so that the buckle opens and maintains the open state. Compared with manual pressing, it is more reliable and will not fall off. There is no need to manually press the buckle all the time, thereby improving work efficiency.

[0006] To achieve the above-mentioned object, in a first aspect, the present invention provides a manual buckle opening device, the manual buckle opening device comprising a base plate, a plurality of movable blocks and a plurality of buckle opening assemblies;

[0007] The bottom plate has a plurality of sliding grooves, and the movable block can be movably arranged on the bottom plate to press the carrier plate onto the bottom plate;

[0008] The buckle assembly includes a push block and a slider, the push block is slidably arranged in the slide groove to drive the buckle on the carrier plate to rotate, and the sliding direction of the push block is parallel to the base plate, the slider is slidably arranged on the push block, and the sliding direction of the slider is perpendicular to the base plate, and the buckle assembly is configured so that when the buckle assembly is in a first state, the push block slides to one end of the slide groove and the slider is located above the slide groove; when the buckle assembly is in a second state, the push block slides to the other end of the slide groove, and the slider and the push block are clamped in the slide groove.

[0009] Optionally, a guide shaft arranged perpendicular to the base plate is inserted into the push block, and the sliding block is slidably mounted on the guide shaft.

[0010] Optionally, a first magnet is installed on the push block, and a second magnet is installed on the slider. The first magnet and the second magnet match each other, and when the slider is located above the slide slot, the first magnet and the second magnet are in contact with each other.

[0011] Optionally, the bottom plate has a positioning groove, and the positioning groove is used to position the carrier plate.

[0012] Optionally, the push block has an inclined surface on one side facing the positioning groove, and the inclined surface gradually approaches the bottom plate from one end of the sliding groove to the other end of the sliding groove.

[0013] Optionally, a third magnet is installed on the slider and a fourth magnet is installed on the base plate. The fourth magnet is arranged opposite to the slide groove, the third magnet and the fourth magnet cooperate with each other, and when the snap assembly is in the second state, the third magnet and the fourth magnet are in contact with each other.

[0014] Optionally, two spaced-apart pressure plates are provided on the base plate, one side of each pressure plate protrudes from the side wall corresponding to the slide groove, and the push block has sliding bars on opposite sides, each sliding bar can be slidably clamped between the corresponding pressure plate and the base plate, and the push block can be slidably clamped between the two pressure plates.

[0015] Optionally, the two pressing plates are connected by a connecting plate, and the connecting plate and the two pressing plates form a U-shaped structure.

[0016] Optionally, the movable block is slidably arranged on the bottom plate, and the sliding direction of the movable block is parallel to the bottom plate. The movable block has a protrusion, and the protrusion is spaced from the bottom plate to clamp the carrier plate.

[0017] In a second aspect, the present invention provides a manual buckle opening method, which is based on the manual buckle opening device described in the first aspect, and includes:

[0018] Placing a carrier plate on the bottom plate, and pressing the carrier plate onto the bottom plate by the movable block;

[0019] Pushing the push block so that the push block slides from one end of the slide slot to the other end of the slide slot, thereby pushing the buckle on the carrier plate to open;

[0020] The slider is lowered so that the slider and the push block are locked in the slide groove, and a display panel is placed on the carrier plate.

[0021] The above-mentioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0022] In general, the above technical solutions conceived by the present invention have the following beneficial effects compared with the prior art:

[0023] For a manual buckle opening device provided by an embodiment of the present invention, when placing a display panel on a carrier, first, place the carrier on the base plate, and press the carrier on the base plate by means of a movable block. At this time, the buckle opening assembly is in a first state, and the push block is spaced apart from the buckle. Next, the push block is pushed so that the push block slides from one end of the slide groove to the other end of the slide groove, thereby squeezing the buckle by sliding the push block to the other end of the slide groove and causing the buckle to rotate, thereby opening the buckle on the carrier and forming an accommodating space at one end of the slide groove for accommodating the slider. Due to the pressing of the movable block on the carrier, the push block pushes the buckle to rotate without pushing the carrier plate to move, rotate, or lift the carrier plate off, so that the carrier plate is always fixed to the base plate in the same state. Next, move the slider down and it will slide into the accommodating space, so that the slider and the push block are stuck in the slide groove. At this time, the space corresponding to the slide groove is filled with the slider and the push block. The slider and the push block are stuck in the slide groove, and both cannot move horizontally, so that the push block can continue to press the buckle, and the restoring force generated by the elastic member will not push the push block back, so that the buckle remains in the open state (at this time, the buckle opening component switches to the second state). Compared with manual pressing, it is more reliable, will not detach, and there is no need to manually press the buckle continuously, so that the display panel can be placed directly on the carrier board.

[0024] After the display panel is in place, slide the slider upwards to disengage the slide slot. At this time, the push block will be pushed back by the buckle under the elastic force of the elastic member (the slider and the push block will retreat together), that is, the push block slides to one end of the slide slot, so that the push block and the buckle are separated, so that the buckle rotates under the elastic force of the elastic member to press the display panel, and finally completes the fixation of the display panel on the carrier. In addition, after the display panel is installed in place, the pressure of the movable block on the carrier is released, so that the carrier can be removed, and the manual buckle opening device can be used to load the next carrier, and the carrier that has completed loading can be transferred to a different workstation by transferring the display panel.

[0025] That is to say, the manual buckle opening device provided by the embodiment of the present invention can realize continuous pressing of the buckle, so that the buckle opens and maintains the open state. Compared with manual pressing, it is more reliable and will not fall off. There is no need for manual continuous pressing of the buckle, which improves work efficiency.

[0041] Example:

[0042] Figure 1 1 is a schematic diagram of a first state of a manual buckle release device provided by an embodiment of the present invention. Figure 2 1 is a schematic diagram of a second state of a manual buckle opening device provided by an embodiment of the present invention. Figure 3 yes Figure 2 Cross-sectional view, combined with Figure 1-Figure 3 As shown, the manual buckle opening device includes a base plate 1, a plurality of movable blocks 2 and a plurality of buckle opening components 3.

[0043] The bottom plate 1 has a plurality of sliding grooves 11 , and the movable block 2 is movably arranged on the bottom plate 1 to press the carrier plate 100 onto the bottom plate 1 .

[0044] Figure 4 Schematic diagram of the structure of the buckle assembly provided by the embodiment of the present invention. Figure 4 As shown, the buckle assembly 3 includes a push block 31 and a slider 32. The push block 31 is slidably arranged in the slide groove 11 to drive the buckle 200 on the carrier plate 100 to rotate, and the sliding direction of the push block 31 is parallel to the base plate 1. The slider 32 is slidably arranged on the push block 31, and the sliding direction of the slider 32 is perpendicular to the base plate 1. The buckle assembly 3 is configured such that when the buckle assembly 3 is in the first state, the push block 31 slides to one end of the slide groove 11 (that is, the end away from the display panel 300), and the slider 32 is located above the slide groove 11. When the buckle assembly 3 is in the second state, the push block 31 slides to the other end of the slide groove 11 (that is, the end close to the display panel 300), and the slider 32 and the push block 31 are clamped in the slide groove 11.

[0045] In a manual release device provided by an embodiment of the present invention, when placing a display panel 300 on a carrier plate 100, first, the carrier plate 100 is placed on the base plate 1 and pressed against the base plate 1 by the movable block 2. At this point, the release assembly 3 is in a first state, with the push block 31 spaced apart from the buckle 200. Next, the push block 31 is pushed, causing it to slide from one end of the chute 11 to the other end. This sliding of the push block 31 to the other end of the chute 11 squeezes the buckle 200, causing it to rotate. This opens the buckle 200 on the carrier plate 100, creating a space at one end of the chute 11 for the slider 32. Because the movable block 2 presses against the carrier plate 100, the push block 31 pushes the buckle 200 to rotate without causing the carrier plate 100 to move, rotate, or lift off, ensuring that the carrier plate 100 remains fixed to the base plate 1 in the same state. Next, the slider 32 is lowered, and the slider 32 slides to the accommodation space, so that the slider 32 and the push block 31 are clamped in the chute 11. At this time, the space corresponding to the chute 11 is filled with the slider 32 and the push block 31, and the slider 32 and the push block 31 are clamped in the chute 11 (see Figure 3 ), both of them cannot move horizontally, so the push block 31 can continue to press the buckle 200, and the restoring force generated by the elastic member will not push the push block 31 back, so that the buckle 200 maintains the open state (at this time, the buckle assembly 3 switches to the second state, see Figure 5), which is more reliable than manual pressing, will not fall off, and there is no need to manually press the buckle 200 continuously, so that the display panel 300 can be placed directly on the carrier board 100.

[0046] After the display panel 300 is placed in place, the slider 32 is slid upwards to disengage the slide groove 11. At this time, the push block 31 is pushed back by the buckle 200 under the elastic force of the elastic member (the slider 32 and the push block 31 retreat together), that is, the push block 31 slides to one end of the slide groove 11, so that the push block 31 is separated from the buckle 200 (at this time, the buckle assembly 3 switches to the first state), and the buckle 200 rotates under the elastic force of the elastic member to press the display panel 300 (see Figure 6 ), thereby finally completing the fixation of the display panel 300 on the carrier 100. Furthermore, after the display panel 300 is in place, the pressure of the movable block 2 on the carrier 100 is released, allowing the carrier 100 to be removed. The manual buckle release device can then load the next carrier 100. The loaded carrier 100 can then be transferred to a different workstation by transferring the display panel 300.

[0047] That is to say, a manual buckle opening device provided by an embodiment of the present invention can realize continuous pressing of the buckle 200, so that the buckle 200 opens and maintains the open state. Compared with manual pressing, it is more reliable and will not fall off. There is no need for manual continuous pressing of the buckle 200, which improves work efficiency.

[0048] It should be noted that the number of the buckle components 3 and the slide grooves 11 is consistent with the number of the buckles 200 on the carrier plate 100 .

[0049] Continue to see Figure 3 and Figure 4 A guide shaft 311 arranged perpendicular to the base plate 1 is inserted into the push block 31 , and the slider 32 is slidably sleeved on the guide shaft 311 .

[0050] In the above embodiment, the guide shaft 311 guides the slider 32 as it moves up and down on the push block 31 .

[0051] Exemplarily, one end of the slider 32 protrudes from the push block 31 for easy manual pressing and driving. The push block 31 has a vertical guide groove, and the other end of the slider 32 slides in cooperation with the guide groove to further guide the slider 32.

[0052] In one implementation of the present invention, a first magnet 312 is installed on the push block 31, and a second magnet 321 is installed on the slider 32. The first magnet 312 and the second magnet 321 match each other, and when the slider 32 is located above the slide slot 11, the first magnet 312 and the second magnet 321 are in contact with each other.

[0053] It is easy to understand that when the display panel 300 is placed in place, the slider 32 is slid upward so that the slider 32 is located above the slide groove 11. At this time, the first magnet 312 and the second magnet 321 are in contact with each other, and the first magnet 312 has an upward magnetic force on the second magnet 321, thereby forming an upward magnetic force on the slider 32 (thereafter, under the elastic force of the elastic member, the push block 31 moves backward, and the buckle assembly 3 switches to the first state), avoiding the problem that the buckle assembly 3 continues to maintain the second state and open the buckle 200 after the slider 32 accidentally moves downward, and ensures that the buckle 200 can be closed smoothly.

[0054] Similarly, a third magnet 322 is installed on the slider 32, and a fourth magnet 13 is installed on the base plate 1. The fourth magnet 13 is arranged opposite to the slide groove 11, and the third magnet 322 and the fourth magnet 13 cooperate with each other. When the buckle 200 component is in the second state, the third magnet 322 and the fourth magnet 13 are attached to each other, so that the buckle assembly 3 can maintain the second state, and the buckle 200 can be kept in the open state, avoiding the push block 31 from accidentally moving up and causing the buckle assembly 3 to release the second state.

[0055] In this embodiment, the bottom plate 1 has a positioning groove 12 for positioning the carrier 100 , thereby achieving precise positioning of the carrier 100 through the positioning groove 12 , ensuring that the buckle 200 and the push block 31 are arranged relative to each other after the carrier 100 is placed.

[0056] In addition, the push block 31 has an inclined surface 313 on one side facing the positioning groove 12 , and the inclined surface 313 gradually approaches the bottom plate 1 from one end of the sliding groove 11 to the other end of the sliding groove 11 .

[0057] It is easy to understand that by providing the inclined surface 313 , the distance between the buckle 200 and the push block 31 when in contact can be increased, thereby increasing the torque and thus saving more effort.

[0058] Figure 7 This is a schematic diagram of the structure of the pressure plate provided by the embodiment of the present invention, combined with Figure 1 and Figure 7 Two spaced-apart pressure plates 14 are provided on the bottom plate 1, and one side of each pressure plate 14 protrudes from the side wall corresponding to the slide groove 11. The push block 31 has slide bars 314 on opposite sides. Each slide bar 314 can be slidably clamped between the corresponding pressure plate 14 and the bottom plate 1 (that is, the bottom surface of the slide groove 11), and the push block 31 can be slidably clamped between the two pressure plates 14.

[0059] In the above embodiment, the pressure plate 14 can form a horizontal guide groove with the bottom surface of the slide groove 11, so that the slide bar 314 slides in cooperation with the guide groove to prevent the push block 31 from detaching from the slide groove 11 in the vertical direction during the horizontal sliding process.

[0060] Exemplarily, the two pressing plates 14 are connected by a connecting plate 15 , and the connecting plate 15 and the two pressing plates 14 form a U-shaped structure, thereby connecting the two pressing plates 14 to form a whole.

[0061] In addition, the connecting plate 15 and the two pressing plates 14 are integrally formed and fixed to the base plate 1 by bolts.

[0062] In one implementation of the present invention, the movable block 2 is slidably arranged on the base plate 1, and the sliding direction of the movable block 2 is parallel to the base plate 1. The movable block 2 has a protrusion 21, and the protrusion 21 is spaced from the base plate 1 to clamp the carrier 100.

[0063] In the above embodiment, when carrier 100 is placed on base plate 1, projection 21 is horizontally spaced from carrier 100. Subsequently, sliding movable block 2 toward the center of base plate 1 causes projection 21 to slide onto carrier 100. Projection 21 then cooperates with base plate 1 to clamp carrier 100.

[0064] For example, base plate 1 includes a sliding seat, with a sliding groove formed between the sliding seat and base plate 1, and movable block 2 slidably engages with the sliding groove. Furthermore, a fifth magnet is mounted on movable block 2, and a sixth magnet is mounted on base plate 1. These two magnets engage with each other, so that when movable block 2 slides onto the clamping carrier 100, the fifth and sixth magnets come into contact with each other.

[0065] It should be noted that, in other embodiments of the present invention, the movable block 2 can also be installed on the base plate 1 by bolts, or installed on the base plate 1 by rotation (i.e., the carrier plate 100 is pressed after rotation), and the present invention does not limit this.

[0066] Figure 8 This is a flow chart of a manual buckle opening method provided by an embodiment of the present invention. Figure 8 As shown, the manual buckle opening method is based on the above-mentioned manual buckle opening device, and the manual buckle opening method includes:

[0067] S1. Place the carrier plate 100 on the base plate 1 and press the carrier plate 100 onto the base plate 1 through the movable block 2.

[0068] S2 . Push the push block 31 so that the push block 31 slides from one end of the slide groove 11 to the other end of the slide groove 11 , thereby pushing the buckle 200 on the carrier plate 100 to open.

[0069] S3 , lower the slider 32 so that the slider 32 and the push block 31 are locked in the slide groove 11 , and place the display panel 300 on the carrier board 100 .

[0070] A manual buckle opening method provided in an embodiment of the present invention can achieve continuous pressing of the buckle 200 so that the buckle 200 opens and maintains the open state. Compared with manual pressing, it is more reliable and will not fall off. There is no need for manual continuous pressing of the buckle 200, which improves work efficiency.

[0071] It will be easily understood by those skilled in the art that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
