Description

Technical Field

[0001] The present invention relates to the technical field of quick-change lock cylinder assembly, and particularly to an automatic precise assembly device for a quick-change lock cylinder. Background Art

[0002] In the automated assembly process of a quick-change lock cylinder, the sleeve, as a core component, whether it can be precisely clamped and positioned has a decisive role in the accuracy and reliability of subsequent assembly processes. Specifically, these subsequent processes include spring installation, torque testing, etc., all of which require the sleeve to achieve extremely high positional accuracy before assembly.

[0003] In the prior art, the clamping of the sleeve usually relies on rigid jaws cooperating with rectangular blocks to grasp the outer wall of the sleeve. This clamping method requires the sleeve to have a high perpendicularity at the initial position, and the jaws need to be strictly centered to ensure the stability of clamping. However, in actual production scenarios, since the sleeve is fed through a conveyor line, it is often easily affected by factors such as mechanical vibration and chute friction, resulting in a certain slight inclination of the sleeve when it enters the clamping station.

[0004] When the traditional jaws encounter an inclined sleeve during the closing process, they will force the sleeve to rotate slightly to make the outer wall of the sleeve fit with the inner wall of the jaws through the frictional torque. Although this rotational movement can achieve the contact of the clamping surface, during this clamping process, the center of the sleeve will shift from the center of the jaws. The center offset of the sleeve will cause the misalignment of the lock cylinder assembly due to error accumulation in subsequent processes (such as oiling, code scanning, snap ring installation). Although in the prior art, the rotation of the sleeve can be restricted by a baffle, during the assembly process of the quick-change lock cylinder, the orientation of the sleeve needs to be precisely controlled, so the baffle needs to be closely fitted with the rectangular edge of the sleeve. However, the close fitting will affect the movement of the sleeve. In addition, the close fitting will increase the wear on the outer wall of the sleeve. When using the baffle to achieve positioning, if a sleeve that does not conform to the standard size is encountered, the size of the sleeve cannot be screened, so incorrect sizes will also enter the next process, and sleeves with incorrect sizes will have an adverse impact on the subsequent assembly process. And when a sleeve with a larger size is encountered, it is easy to get stuck between the two baffles, making the sleeve unable to move forward.

[0005] Therefore, an automatic precise assembly device for a quick-change lock cylinder is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic precise assembly device for a quick-change lock cylinder, in order to solve the problem that when the jaws clamp an inclined sleeve, the center of the sleeve shifts from the center of the jaws, thereby reducing the accuracy during subsequent assembly. By clamping the sleeve from the top by a clamping component, during the upward movement of the clamping component, the position of the sleeve is adjusted by a regulating component pushing the edge of the sleeve.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] An automatic precise assembly device for a quick-change lock cylinder core, which is used in cooperation with a sleeve, includes a transfer component, and also includes a sliding plate, a fixed cylinder, a clamping component and an adjusting component. The sliding plate is connected to the front side of the transfer component, the fixed cylinder is connected to the bottom of the sliding plate, the adjusting component is connected to the lower side of the fixed cylinder, the clamping component is connected to the inside of the fixed cylinder, the sleeve includes a cylinder body and a rectangular block, the clamping component is connected to the upper side of the rectangular block, and the rectangular block is clamped by the clamping component to drive the whole sleeve to move upward inside the adjusting component. When the sleeve moves upward, the edge of the rectangular block is pushed by the inner wall of the adjusting component to change the deflection angle of the sleeve.

[0009] In the prior art, when the sleeve is fixed by the clamping jaws, the short side of the rectangular block faces forward. In the above solution, the edge of the sleeve is pushed by the adjusting component during the upward movement of the sleeve to adjust the deflection angle of the sleeve, so that the short side of the sleeve faces forward. At the same time, the adjusting component can also align the center position of the sleeve with the center position of the clamping component, further improving the precision during clamping. Moreover, the adjusting component cooperates with the clamping component, and can also screen the size of the sleeve during the adjustment process, so that only the sleeves that meet the standard size can enter the subsequent assembly steps.

[0010] Preferably, the clamping component includes a suction cup, a telescopic rod, a bearing plate, a hollow column, a connecting plate, a mounting plate and a hose. The telescopic rod is connected above the sliding plate, the bearing plate is connected to the lower end of the telescopic rod, a plurality of the hollow columns are connected to the lower side of the bearing plate, the mounting plate is connected to the lower side of the hollow column, a plurality of hoses are connected to the lower side of the mounting plate and communicate with the hollow column, the connecting plate is connected to the lower end of the hose, and a plurality of suction cups are connected to the lower side of the connecting plate and communicate with the hose. The clamping component further includes a negative pressure cavity, an air inlet and a conical plug. The negative pressure cavity is opened inside the connecting plate and communicates with the hose. A plurality of the air inlets are opened on the lower side of the connecting plate and communicate with the negative pressure cavity. The suction cup communicates with the negative pressure cavity. The conical plug is connected to the bottom center of the connecting plate and is located at the central position. The conical plug is made of rubber material.

[0011] In the above solution, a pump in the prior art is used to extract the gas inside the hollow column. At this time, the gas inside the negative pressure chamber enters the hollow column, thereby forming a negative pressure inside the negative pressure chamber. Since the bottom of the suction cup is connected to the negative pressure chamber, a negative pressure will also be formed on the lower side of the suction cup, thereby fixing the object. Fixing by means of the suction cup avoids the original hard contact, which may cause damage to the sleeve during the clamping process. Moreover, fixing by the suction cup can adapt to any deflection angle of the sleeve, and during suction, it avoids the situation in the original clamping process where the sleeve is forced to rotate due to the deflection angle of the sleeve and is damaged by hard extrusion. In the prior art, there is a through hole for installing parts at the top of the sleeve. During the process of the connecting plate moving downward to clamp the sleeve, before the suction cup contacts the sleeve, the conical plug at the bottom of the connecting plate will first enter the through hole at the top of the sleeve and push the connecting plate to move, aligning the center position of the sleeve with the center position of the connecting plate, thereby realizing the preliminary positioning of the sleeve.

[0012] Preferably, the adjusting assembly includes an adjusting sleeve, an adjusting groove, a rotating shaft, and a reset spring. The adjusting sleeve is connected to the lower side of the fixed cylinder. The adjusting groove is formed on the lower side of the adjusting sleeve. The width and length of the adjusting groove gradually decrease from bottom to top. The minimum width and length of the adjusting groove are the same as those of the rectangular block. The rotating shaft is connected between the connecting plate and the mounting plate. The reset spring is connected to the outer wall of the rotating shaft.

[0013] In the above solution, when the clamping assembly drives the sleeve to move upward, the inner wall of the adjusting sleeve pushes the short side edge of the rectangular block, causing the sleeve to rotate below the connecting plate, thereby adjusting the orientation of the sleeve. Since the sleeve only has a small deflection when moving on the conveying line, when the edge of the rectangular block contacts the inner wall of the adjusting sleeve, it is still the short side contacting the short side. When the short sides contact each other, a perpendicular thrust will be generated on the short side of the rectangular block. As the rising distance increases, the length of the adjusting groove becomes smaller and smaller, increasing the pushing amplitude of the short side of the adjusting groove on the short side of the rectangular block, causing the sleeve to deflect while moving upward until the inner wall of the adjusting groove fits the edge of the rectangular block, thereby rotating the sleeve to the correct direction.

[0014] Preferably, the inner wall of the adjusting sleeve is arc-shaped, and the radian gradually decreases from bottom to top.

[0015] In the above solution, the arc-shaped design of the inner wall of the adjusting sleeve enables the edge of the deflected sleeve to just contact the inner wall of the adjusting groove, changing the point contact to a line contact, thereby reducing the pressure between the rectangular block and the adjusting groove, and thus reducing the damage to the sleeve.

[0016] Preferably, the adjusting assembly further includes a fixing groove, a sliding groove and a sliding block. The fixing groove is opened in the middle of the upper side of the adjusting sleeve and communicates with the adjusting groove. The length and width of the fixing groove are the same as those of the rectangular block, and the two sides of the long side of the fixing groove are the left and right sides. The sliding groove is opened on the tops of the mounting plate and the bearing plate, and the two sliding grooves are perpendicular to each other. The sliding block is slidably connected to the inside of the sliding groove. Compression springs are connected to both sides of the sliding block, and the two sliding blocks are respectively connected to the rotating shaft and the telescopic rod.

[0017] In the above solution, since the bearing plate is connected to the telescopic rod through the sliding groove and the sliding block, the bearing plate can move in the front-back direction at the lower end of the telescopic rod. The mounting plate is connected to the upper end of the rotating shaft through the sliding groove and the sliding block, and the rotating shaft can move left and right below the mounting plate. Also, since the suction cup is connected to the lower side of the mounting plate, and the mounting plate is connected to the lower side of the bearing plate through the hollow column, when the suction cup drives the sleeve to move upward, the sleeve can move back and forth and left and right. When the suction cup drives the sleeve to move upward as a whole through the fixed rectangular block, the inner wall of the adjusting sleeve will also push the sleeve towards the center of the adjusting sleeve, so that when the sleeve moves to the top, the center of the sleeve is aligned with the center of the adjusting sleeve. Thus, when the sleeve is fixed on the transplanting assembly and moves, its position is unified with that of the adjusting sleeve, making the subsequent processing steps more accurate. Since the adjusting groove communicates with the fixing groove, after the sleeve is adjusted through the adjusting groove and continues to move upward, the rectangular block can enter the fixing groove. Because the width and length of the fixing groove are the same as those of the rectangular block, the inner wall of the fixing groove will fit with the inner wall of the rectangular block, thus preventing deviation during the movement of the sleeve driven by the transfer assembly and also preventing products with too large dimensions from entering the adjusting groove. When the suction cup continues to move upward, the fixing groove prevents the sleeve from moving upward, so that products with too large dimensions are separated from the suction cup and fall into the recycling box, thus playing a screening role. Since in the assembly process of the lock core, if the size of the sleeve is too large or too small, the assembly of the lock core cannot be completed. Therefore, before the lock core is assembled, not only the position of the sleeve needs to be adjusted for subsequent precise assembly, but also the size of the sleeve needs to be accurately screened. In the prior art, the size of the clamped sleeve is photographed for screening. Compared with the prior art, the present invention restricts the upward movement of the large-sized rectangular block through the adjusting groove for self-screening, and no longer screens by confirming the size of the sleeve, simplifying the composition of the equipment and reducing the equipment cost.

[0018] Preferably, a sealing assembly is connected above the connecting plate. The sealing assembly includes a movable rod, a sealing plug, a sealing ring and a vertical spring. The movable rod is connected inside the negative pressure chamber and its upper end extends outside the upper negative pressure chamber. The sealing plug is connected to the lower end of the movable rod and cooperates with the air inlet. The vertical spring is connected to the lower side of the sealing plug, and the sealing ring is connected to the upper side of the connecting plate.

[0019] In the above solution, initially, the sealing plug blocks the air inlet, so that the negative pressure chamber has only one outlet, which is the hose. When the connecting plate moves upward, the upper side of the inner wall of the fixing groove pushes the movable rod, causing the movable rod to drive the sealing plug to move downward, thereby opening the air inlet on the lower side of the negative pressure chamber. As a result, negative pressure is no longer generated on the inner wall of the negative pressure chamber. At the same time, the sealing ring fits tightly with the top of the fixing groove, so that the upper part of the fixing groove is sealed. Also, because the side size of the fixing groove is the same as the size of the rectangular block, when the rectangular block enters the inside of the fixing groove, the outer wall of the rectangular block will fit tightly with the inner wall of the fixing groove. And during the preliminary positioning, the conical plug blocks the through hole at the top of the sleeve. Therefore, the inside of the fixing groove becomes a sealed space. At this time, the gas inside the fixing groove is sucked away by the hollow column, so that negative pressure is formed inside the fixing groove and the rectangular block is fixed. When the size of the rectangular block is too small, it cannot fit tightly with the inside of the fixing groove. Therefore, the inside of the fixing groove cannot become a sealed space, and negative pressure cannot be formed. However, at this time, negative pressure is no longer generated at the bottom of the suction cup, so that the sleeve of the rectangular block with a smaller size falls off from below the suction cup, thus playing a role in screening the rectangular blocks with smaller sizes and further improving the accuracy of screening.

[0020] Preferably, a plurality of balls are connected to the inner wall of the adjusting sleeve, and the balls cooperate with the outer wall of the sleeve.

[0021] In the above solution, balls are connected to the inner wall of the adjusting sleeve. When the sleeve moves upward, the edge of the rectangular block fits with the balls. By using the rolling friction of the balls instead of sliding friction, the friction force received during the upward movement of the sleeve is reduced.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. By setting the adjusting component, when the inner wall of the adjusting groove at the bottom of the adjusting sleeve contacts the rectangular block above the sleeve, a vertical thrust is generated on the short side of the rectangular block, so that the sleeve deflects while moving upward until the inner wall of the adjusting groove fits with the edge of the rectangular block, thus rotating the sleeve to the correct direction. At the same time, through the cooperation of the sliding groove and the slider, the sleeve can move in four directions, namely, forward, backward, left, and right, during the upward movement. Then, by using the adjusting groove to push the sleeve to move, the central position of the sleeve is aligned with the central position of the adjusting sleeve. Furthermore, when the sleeve is fixed on the transplanting component and moves, its position is unified with that of the adjusting sleeve, so that the subsequent processing steps are more accurate. And during the adjustment process, in cooperation with the clamping component, the size of the sleeve can also be screened, so that only the sleeves meeting the standard size enter the subsequent assembly steps, further improving the accuracy of assembly.

[0024] 2. By setting the adjusting groove and the fixing groove, when the sleeve is adjusted by the adjusting groove, it will continue to move upward, so that the rectangular block above the sleeve fits with the inner wall of the fixing groove. The fixing groove limits the deflection of the sleeve during the movement, thereby improving the accuracy of assembly. At the same time, because the size of the fixing groove is the same as the size of the rectangular block, when the size of the sleeve is too large, the suction cup will be restricted by the adjusting groove when it continues to drive the adjusting sleeve to move upward. Since the top of the rectangular block is fixed by the suction cup, compared with the clamping claw method, the suction cup fixing method can make the four edges of the rectangular block contact with the adjusting groove at the same time, which can accurately limit the size of the rectangular block, so that the rectangular block with a larger size cannot enter the fixed sleeve, resulting in the sleeve being unable to move upward. Under the resistance of the adjusting groove, the product with a larger size is separated from the suction cup, thereby playing a screening role.

[0025] 3. By setting up a sealing component and a clamping component and fixing them by means of a suction cup, the original hard contact is changed into a flexible contact, thereby avoiding damage to the sleeve during the clamping process, and fixing by a suction cup can adapt to any deflection angle of the sleeve, avoiding damage to the sleeve caused by the deflection angle of the sleeve being forced to be hard squeezed and rotated. When the connecting plate in the clamping component moves to the top of the fixed groove, the top of the fixed groove fits tightly with the sealing ring and the outer wall of the rectangular block, so that the inside of the fixed groove becomes a sealed space. When the gas inside the fixed groove is drawn away by the hollow column, a negative pressure is formed inside the fixed groove, and the rectangular block is fixed. When the size of the rectangular block is relatively small, it cannot fit tightly with the inside of the fixed groove, so that the inside of the fixed groove cannot form a sealed space, and thus negative pressure cannot be formed, so that the sleeve of the rectangular block with a smaller size falls off from under the suction cup, thereby playing a role in screening rectangular blocks with a smaller size.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention, and in combination with the working state, its structural features will be made more detailed. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 to 8 , the present invention provides an automatic precise assembly device for a quick-change lock cylinder, and the technical solution is as follows:

[0037] An automatic precise assembly device for a quick-change lock cylinder, referring to Figure 1 and Figure 2, used in cooperation with the sleeve 1, includes a transfer component 2, and also includes a sliding plate 3, a fixed cylinder 4, a clamping component 5 and an adjusting component 6. The sliding plate 3 is connected to the front side of the transfer component 2. The fixed cylinder 4 is connected to the bottom of the sliding plate 3. The adjusting component 6 is connected to the lower side of the fixed cylinder 4. The clamping component 5 is connected to the inside of the fixed cylinder 4. The sleeve 1 includes a cylinder 101 and a rectangular block 102. The clamping component 5 is connected to the upper side of the rectangular block 102. By clamping the rectangular block 102 with the clamping component 5, the whole sleeve 1 is driven to move upward inside the adjusting component 6. When the sleeve 1 moves upward, the edge of the rectangular block 102 is pushed by the inner wall of the adjusting component 6 to change the deflection angle of the sleeve 1. When the clamping component 5 clamps the sleeve 1 through the adjusting component 6, the orientation of the sleeve 1 can be adjusted automatically, so that the short side of the sleeve 1 faces the front side. At the same time, the adjusting component 6 can also align the central position of the sleeve 1 with the central position of the clamping component 5, further improving the accuracy during clamping. During the upward movement of the sleeve 1, the adjusting component 6 pushes the edge of the sleeve 1 to adjust the deflection angle of the sleeve 1.

[0038] As an embodiment of the present invention, referring to Figure 3 and Figure 8 , the clamping component 5 includes a suction cup 501, a telescopic rod 502, a bearing plate 503, a hollow column 504, a connecting plate 505, a mounting plate 506 and a hose 507. The telescopic rod is connected above the sliding plate 3. The bearing plate 503 is connected to the lower end of the telescopic rod 502. A plurality of the hollow columns 504 are connected to the lower side of the bearing plate 503. The mounting plate 506 is connected to the lower side of the hollow column 504. A plurality of hoses 507 are connected to the lower side of the mounting plate 506 and communicate with the hollow column 504. The connecting plate 505 is connected to the lower end of the hose 507. A plurality of suction cups 501 are connected to the lower side of the connecting plate 505 and communicate with the hose 507. First, the telescopic rod 502 is extended to make the bearing plate 503 move downward. When the bearing plate 503 moves downward, it will drive the hollow column 504, the connecting plate 505, the mounting plate 506 and the suction cup 501 to move downward together, so that the suction cup 501 contacts the top of the rectangular block 102. Then, the air inside the hollow column 504 is pumped out by a pump in the prior art, so that negative pressure appears at the bottom of the suction cup 501 to fix the rectangular block 102 below the suction cup 501. Finally, the telescopic rod 502 is started again to make the telescopic rod 502 shorten to drive the sleeve 1 to move upward. Fixing by the suction cup 501 avoids the original hard contact, which may cause damage to the sleeve 1 during the clamping process. And fixing by the suction cup 501 can adapt to any deflection angle of the sleeve 1, and when sucking, it avoids the situation in the original clamping that due to the deflection angle of the sleeve 1, the sleeve 1 is forced to rotate under hard extrusion and is damaged;

[0039] The clamping assembly 5 further includes a negative pressure chamber 508, an air inlet 509, and a conical plug 5010. The negative pressure chamber 508 is opened inside the connecting plate 505 and communicates with the hose 507. A plurality of the air inlets 509 are opened on the lower side of the connecting plate 505 and communicate with the negative pressure chamber 508. The suction cup 501 communicates with the negative pressure chamber 508. When the pump extracts the gas inside the hollow column 504, the gas inside the negative pressure chamber 508 enters the hollow column 504 through the hose 507, so that a negative pressure is formed inside the negative pressure chamber 508. Since the bottom of the suction cup 501 communicates with the negative pressure chamber 508, a negative pressure will also be formed on the lower side of the suction cup 501, thereby fixing the object. The conical plug 5010 is connected to the bottom of the connecting plate 505 and is located at the central position. The conical plug 5010 is made of rubber. Before the suction cup 501 contacts the sleeve 1, the connecting plate 505 is pushed to move by allowing the conical plug 5010 to enter the through hole at the top of the sleeve 1, so that the central position of the sleeve 1 is aligned with the central position of the connecting plate 505, thereby realizing the preliminary positioning of the sleeve 1.

[0040] As an implementation manner of the present invention, refer to Figure 3 and Figure 5 , the adjusting assembly 6 includes an adjusting sleeve 601, an adjusting groove 602, a rotating shaft 603, and a return spring 604. The adjusting sleeve 601 is connected to the lower side of the fixed cylinder 4. The adjusting groove 602 is opened on the lower side of the adjusting sleeve 601. The width and length of the adjusting groove 602 gradually decrease from bottom to top. The minimum width and length of the adjusting groove 602 are the same as those of the rectangular block 102. The rotating shaft 603 is connected between the connecting plate 505 and the mounting plate 506. The return spring 604 is connected to the outer wall of the rotating shaft 603. The clamping assembly 5 drives the sleeve 1 to move upward to contact the inner wall of the adjusting sleeve 601, so that the short side of the rectangular block 102 contacts the short side of the adjusting groove 602. When the short sides contact each other, a vertical thrust will be generated on the short side of the rectangular block 102. As the rising distance increases, the length of the adjusting groove 602 becomes smaller and smaller, so that the pushing amplitude of the short side of the adjusting groove 602 on the short side of the rectangular block 102 also increases, thereby causing the sleeve 1 to deflect while moving upward until the inner wall of the adjusting groove 602 fits the edge of the rectangular block 102, so that the sleeve 1 rotates to the correct direction, thereby realizing the adjustment of the orientation of the sleeve 1.

[0041] As an implementation manner of the present invention, refer to Figure 7 , the inner wall of the adjusting sleeve 601 is arc-shaped, and the radian gradually decreases from bottom to top, so that the point contact becomes a line contact, thereby reducing the pressure between the rectangular block 102 and the adjusting groove 602, and thus reducing the damage to the sleeve 1.

[0042] As an implementation manner of the present invention, refer to Figure 3 , Figure 4 , Figure 5and Figure 6 , the adjusting assembly 6 further includes a fixing groove 605, a sliding groove 606 and a sliding block 607. The fixing groove 605 is opened in the middle of the upper side of the adjusting sleeve 601 and communicates with the adjusting groove 602. The length and width of the fixing groove 605 are the same as those of the rectangular block 102, and the two sides of the long side of the fixing groove 605 are the left and right sides, so as to prevent deviation during the movement of the transfer assembly 2 driving the sleeve 1, and at the same time prevent products with too large dimensions from entering the adjusting groove 602. When the suction cup 501 continues to move upward, the fixing groove 605 prevents the sleeve 1 from moving upward, so that products with too large dimensions are separated from the suction cup 501 and fall into the recycling box, so that a screening function can be achieved during the adjustment process. The sliding groove 606 is opened at the tops of the mounting plate 506 and the bearing plate 503, and the two sliding grooves 606 are perpendicular to each other. The sliding block 607 is slidably connected to the inside of the sliding groove 606. Compression springs 608 are connected to both sides of the sliding block 607. The two sliding blocks 607 are respectively connected to the rotating shaft 603 and the telescopic rod 502. Because the bearing plate 503 is connected to the telescopic rod 502 through the sliding groove 606 and the sliding block 607, the bearing plate 503 can move back and forth in the front and rear directions at the lower end of the telescopic rod 502. The mounting plate 506 is connected to the upper end of the rotating shaft 603 through the sliding groove 606 and the sliding block 607, and the rotating shaft 603 can move left and right below the mounting plate 506. The mounting plate 506 is connected to the lower side of the bearing plate 503 through the connecting plate 505 and the hollow column 504. Therefore, when the suction cup 501 drives the sleeve 1 to move upward, the sleeve 1 can move back and forth, left and right. When the suction cup 501 drives the sleeve 1 to move upward as a whole through the fixed rectangular block 102, the inner wall of the adjusting sleeve 601 will also push the sleeve 1 towards the center of the adjusting sleeve 601, so that when the sleeve 1 moves to the top, the center of the sleeve 1 is aligned with the center of the adjusting sleeve 601, thereby making the subsequent processing steps more accurate.

[0043] As an embodiment of the present invention, refer to Figure 8, a sealing assembly 7 is connected above the connecting plate 505. The sealing assembly 7 includes a movable rod 701, a sealing plug 702, a sealing ring 703 and a vertical spring 704. The movable rod 701 is connected inside the negative pressure chamber 508, and its upper end extends outside the upper negative pressure chamber 508. The sealing plug 702 is connected to the lower end of the movable rod 701 and cooperates with the air inlet 509. The vertical spring 704 is connected to the lower side of the sealing plug 702, and the upper side of the inner wall of the fixed groove 605 pushes the upper side of the movable rod 701, so that the movable rod 701 drives the sealing plug 702 to move downward, thereby opening the air inlet 509 on the lower side of the negative pressure chamber 508, and further making the inner wall of the negative pressure chamber 508 no longer generate negative pressure. The sealing ring 703 is connected to the upper side of the connecting plate 505. When the connecting plate 505 moves into the fixed groove 605, the sealing ring 703 is in close contact with the top of the fixed groove 605, so as to seal the upper part of the fixed groove 605. Since the side size of the fixed groove 605 is the same as the size of the rectangular block 102, when the rectangular block 102 enters the fixed groove 605, the outer wall of the rectangular block 102 will be in close contact with the inner wall of the fixed groove 605. Therefore, the inside of the fixed groove 605 becomes a sealed space. At this time, the gas inside the fixed groove 605 is pumped away by the hollow column 504, so that a negative pressure is formed inside the fixed groove 605 and the rectangular block 102 is fixed. When the size of the rectangular block 102 is too small, it cannot be in close contact with the inside of the fixed groove 605, so the inside of the fixed groove 605 cannot become a sealed space, and thus no negative pressure can be formed. However, at this time, no negative pressure is generated at the bottom of the suction cup 501, so that the sleeve 1 of the rectangular block 102 with a smaller size falls off from below the suction cup 501, thereby playing a role in screening the rectangular block 102 with a smaller size.

[0044] As an embodiment of the present invention, refer to Figure 7 , a plurality of balls 8 are connected to the inner wall of the adjusting sleeve 601. The balls 8 are connected to the outer wall of the sleeve 1. When the sleeve 1 moves upward, the edge of the rectangular block 102 is in contact with the balls 8. The rolling friction of the balls 8 is used instead of sliding friction, so as to reduce the friction force received by the sleeve 1 during the upward movement.

[0045] Working principle: During use, first control the telescopic rod 502 to move downward, driving the connecting plate 505 to move downward. There is a through-hole for installing parts at the top of the existing sleeve 1. During the downward movement of the connecting plate 505, the conical plug 5010 enters the through-hole at the top of the sleeve 1 and pushes the connecting plate 505 to move, aligning the central position of the sleeve 1 with the central position of the connecting plate 505, thus achieving the preliminary positioning of the sleeve 1. Then, the suction cup 501 contacts the top of the sleeve 1, and the gas inside the hollow column 504 is pumped out through the prior art pump, causing negative pressure to appear at the bottom of the suction cup 501, thereby fixing the top of the sleeve 1 through the suction cup 501. Then, control the telescopic rod 502 to shorten, driving the sleeve 1 to move upward through the suction cup 501. To solve the problem that when the clamping jaw clamps the inclined sleeve 1, the center of the sleeve 1 is offset from the center of the clamping jaw, fix the sleeve 1 from the top through the suction cup 501, and during the upward movement of the sleeve 1, adjust the position of the sleeve 1 by pushing the edge of the rectangular block 102 through the adjustment groove 602 in the adjustment sleeve 601. At the same time, during the adjustment process, sleeves 1 that do not meet the standard size can also be screened out;

[0046] Process of the suction cup 501 adsorbing: When the gas inside the hollow column 504 is pumped out, at this time, the gas inside the negative pressure chamber 508 enters the hollow column 504 through the hose 507, thus forming negative pressure inside the negative pressure chamber 508. Because the bottom of the suction cup 501 is connected to the negative pressure chamber 508, negative pressure will also be formed on the lower side of the suction cup 501, thereby fixing the object;

[0047] Adjustment process: During the upward movement, the short side of the rectangular block 102 contacts the short side of the adjustment groove 602, thus generating a thrust on the short side of the rectangular block 102, and further causing the sleeve 1 to drive the connecting plate 505 to deflect at the lower end of the rotating shaft 603, so that the sleeve 1 rotates to the correct position. During the upward movement of the sleeve 1, the long side of the adjustment groove 602 pushes the sleeve 1 to move left and right, and the rotating shaft 603 moves left and right below the mounting plate 506 through the slider 607. The short side of the adjustment groove 602 pushes the rectangular block 102 to move back and forth. At this time, the sleeve 1 drives the hollow column 504 to move back and forth through the mounting plate 506. Because the bearing plate 503 is connected to the telescopic rod 502 through the chute 606 and the slider 607, the bearing plate 503 can move back and forth below the telescopic rod 502, so the hollow column 504 can drive the bearing plate 503 to move back and forth. Finally, the rectangular block 102 enters the fixing groove 605, so that the center of the sleeve 1 is aligned with the center of the adjustment sleeve 601. When transported to the next assembly position, turn off the pump so that there is no negative pressure at the bottom of the suction cup 501, thereby putting down the sleeve 1;

[0048] When the rectangular block 102 enters the fixed groove 605, the upper side of the inner wall of the fixed groove 605 pushes the movable rod 701 to move downward, and the sealing plug 702 is driven downward by the movable rod 701, and the air inlet 509 on the lower side of the negative pressure chamber 508 is opened, so that the inner wall of the negative pressure chamber 508 no longer generates negative pressure, and the suction cup 501 no longer absorbs the rectangular block 102. At the same time, the sealing ring 703 fits tightly with the top of the fixed groove 605, and because the through hole at the top of the sleeve 1 is blocked by the conical plug 5010, The upper part of the fixing groove 605 is sealed, because the size of the fixing groove 605 is the same as that of the rectangular block 102. When the rectangular block 102 enters the fixing groove 605, the outer wall of the rectangular block 102 will fit tightly with the inner wall of the fixing groove 605, thereby sealing the lower side of the fixing groove 605, and then making the inside of the fixing groove 605 a sealed space. At this time, the gas inside the fixing groove 605 is sucked away by the hollow column 504, so that a negative pressure is formed inside the fixing groove 605, and the rectangular block 102 is fixed;

[0049] When encountering a rectangular block 102 of a larger size, since the minimum length and width of the adjustment slot 602 are the same as those of a rectangular block 102 of a standard size, the rectangular block 102 of a larger size cannot pass through the adjustment slot 602 and enter the fixed slot 605, and is blocked below the fixed slot 605, and cannot be further driven upward by the suction cup 501, and falls off from the suction cup 501 under the pressure of the adjustment slot 602, thereby screening the large-sized screening rectangular blocks 102;

[0050] When encountering a rectangular block 102 with a smaller size, after the rectangular block 102 enters the fixed groove 605, the outer wall of the rectangular block 102 with a smaller size cannot be tightly attached to the inner wall of the fixed groove 605, so that the interior of the fixed groove 605 cannot form a sealed space, and thus negative pressure cannot be formed. However, at this time, since the air inlet 509 is opened, there is no longer any negative pressure inside the negative pressure chamber 508, and thus the bottom of the suction cup 501 no longer generates negative pressure, so that the sleeve 1 with a smaller rectangular block 102 falls off from under the suction cup 501, thereby playing the role of screening out the rectangular blocks 102 with smaller sizes.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
