[0010] Optionally, a first magnet is inserted on the push block, and a second magnet is inserted on the sliding block. The first magnet matches the second magnet, and when the sliding block is located above the sliding 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 in a direction from one end of the sliding groove to the other end of the sliding groove.

[0013] Optionally, a third magnet is inserted on the slider, a fourth magnet is inserted on the bottom plate, the fourth magnet is arranged opposite to the slide slot, the third magnet and the fourth magnet cooperate with each other, and when the buckle assembly is in the second state, the third magnet and the fourth magnet are in contact with each other.

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

[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;

[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, compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects:

[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 bottom plate, and press the carrier on the bottom plate by 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, push the push block 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 to rotate the buckle, thereby opening the buckle on the carrier and forming an accommodating space at one end of the slide groove to accommodate the slider. Due to the pressing of the carrier by the movable block, the push block pushes the buckle to rotate without pushing the carrier to move, rotate, or lift the carrier, so that the carrier is always fixed on the bottom plate in the same state. Next, move the slider down and it will slide to 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 backward, so that the buckle maintains an 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.

[0024] After the display panel is in place, slide the slider upward 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 spaced apart, 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 load the next carrier, and the carrier that has completed loading can transfer the display panel to a different station by transferring the carrier.

[0025] That is to say, a manual buckle opening device provided in an embodiment of the present invention can achieve continuous pressing of the buckle so that the buckle opens and maintains an open state. Compared with manual pressing, it is more reliable and will not come off. There is no need for manual continuous pressing of the buckle, thereby improving work efficiency.

[0041] Example:

[0042] Figure 1 is a schematic diagram of a first state of a manual buckle opening device provided by an embodiment of the present invention, Figure 2 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 The cross-sectional view of 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 slide 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 is a schematic diagram of the structure of the buckle assembly provided by an embodiment of the present invention, such as 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 a first state, the push block 31 slides to one end of the slide groove 11 (i.e., 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 a second state, the push block 31 slides to the other end of the slide groove 11 (i.e., 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] For a manual buckle opening device provided by an embodiment of the present invention, when placing a display panel 300 on a carrier 100, first, the carrier 100 is placed on the bottom plate 1, and the carrier 100 is pressed onto the bottom plate 1 by the movable block 2. At this time, the buckle opening component 3 is in the first state, and the push block 31 is spaced from the buckle 200. Next, the push block 31 is pushed so that the push block 31 slides from one end of the slide groove 11 to the other end of the slide groove 11, so that the buckle 200 is squeezed by the push block 31 sliding to the other end of the slide groove 11 to rotate the buckle 200, so that the buckle 200 on the carrier 100 can be opened, and one end of the slide groove 11 forms an accommodating space for accommodating the slider 32. Due to the pressing of the movable block 2 on the carrier 100, the push block 31 pushes the buckle 200 to rotate without pushing the carrier 100 to move, rotate or lift the carrier 100, so that the carrier 100 is always fixed on the bottom 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 stuck in the slide groove 11. At this time, the space corresponding to the slide groove 11 is filled with the slider 32 and the push block 31, and the slider 32 and the push block 31 are stuck in the slide groove 11 (see Figure 3 ), both of them cannot move horizontally, so that 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 opening component 3 switches to the second state, see Figure 5), which is more reliable than manual pressing, will not come off, and does not require manual continuous pressing of the buckle 200, so that the display panel 300 can be placed directly on the carrier 100.

[0046] After the display panel 300 is placed in place, the slider 32 is slid upward to disengage the slide slot 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 slot 11, so that the push block 31 is spaced apart 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 FIG. 2 ). Figure 6 ), and finally the display panel 300 is fixed on the carrier 100. In addition, after the display panel 300 is installed in place, the pressing of the movable block 2 on the carrier 100 is released, so that the carrier 100 can be taken away, and the manual buckle opening device can load the next carrier 100, and the carrier 100 that has been loaded can be transferred to a different station by transferring the carrier 100.

[0047] That is to say, a manual buckle opening device provided in an embodiment of the present invention can realize continuous pressing of the buckle 200 so that the buckle 200 opens and maintains an open state. Compared with manual pressing, it is more reliable and will not come off. There is no need for manual continuous pressing of the buckle 200, thereby improving 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 bottom plate 1 is inserted on 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 to rise and fall on the push block 31 .

[0051] Exemplarily, one end of the slider 32 protrudes from the push block 31, which is convenient for manual pressing and driving. The push block 31 has a vertical guide groove, and the other end of the slider 32 is slidably matched with the guide groove to further guide the slider 32.

[0052] In one implementation of the present invention, a first magnet 312 is inserted on the push block 31, and a second magnet 321 is inserted 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 put in place, the slider 32 is slid up so that the slider 32 is located above the slide slot 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, the push block 31 moves backward under the elastic force of the elastic member, and the buckle assembly 3 switches to the first state), thereby 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, thereby ensuring 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 bottom plate 1. The fourth magnet 13 is arranged opposite to the slide groove 11. The third magnet 322 and the fourth magnet 13 cooperate with each other, and 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 component 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 component 3 to release the second state.

[0055] In this embodiment, the bottom plate 1 has a positioning groove 12 for positioning the carrier 100 , so that the carrier 100 can be accurately positioned through the positioning groove 12 to ensure 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 is a schematic diagram of the structure of the pressing plate provided in an 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, one side of each pressure plate 14 protrudes from the side wall corresponding to the slide groove 11, and 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 (i.e., 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 horizontal sliding.

[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 the carrier 100 is placed on the bottom plate 1, the projection 21 is spaced apart from the carrier 100 in the horizontal direction. Afterwards, the movable block 2 is slid toward the middle of the bottom plate 1 to cause the projection 21 to slide onto the carrier 100, and the projection 21 can cooperate with the bottom plate 1 to clamp the carrier 100.

[0064] For example, the bottom plate 1 has a sliding seat, a sliding groove is formed between the sliding seat and the bottom plate 1, and the movable block 2 slides in cooperation with the sliding groove. In addition, the movable block 2 is provided with a fifth magnet, and the bottom plate 1 has a sixth magnet, and the two magnets cooperate with each other. When the movable block 2 slides to the clamping carrier 100, the fifth magnet and the sixth magnet are in 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 (that is, the carrier plate 100 is pressed after rotation), and the present invention is not limited to this.

[0066] Figure 8 is a flow chart of a manual buckle opening method provided by an embodiment of the present invention, such as 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 100 on the base plate 1 , and press the carrier 100 onto the base plate 1 through the movable block 2 .

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

[0069] S3 , the sliding block 32 is lowered so that the sliding block 32 and the pushing block 31 are locked in the sliding groove 11 , and the display panel 300 is placed 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 an open state. Compared with manual pressing, it has higher reliability and will not come off. There is no need for manual continuous pressing of the buckle 200, thereby improving work efficiency.

[0071] It will be easily understood by those skilled in the art that the above description is only 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 protection scope of the present invention.
