Description

Technical Field

[0001] The present invention relates to the technical field of hinge assembly, and particularly relates to a hinge assembly device. Background Art

[0002] A hinge is a connecting piece, a device or part used to connect two parts of a machine, vehicle, door, window, or utensil, and one or both of the connected parts can rotate around the axis of the hinge.

[0003] Chinese Patent with the authorization announcement number CN117300619B discloses an automatic hinge assembly device, including a steering unit. A positioning component is provided on the steering unit, and the positioning component is used to place two leaf plates of the hinge. The steering unit is used to control the rotation of the positioning component. A blanking component is also provided on the steering unit, which can push the assembled hinge on the positioning component away from the steering unit. An extrusion unit is provided on one side of the steering unit, and the extrusion unit is used to push the pin shaft of the hinge into the insertion hole between the two leaf plates. The extrusion unit includes a pre-installation shell. A vertical column of pin shafts is placed in the pre-installation shell. A through hole is opened at the upper end of the pre-installation shell. A first cylinder is provided at the rear side position of the pre-installation shell. The first cylinder is fixedly connected to the pre-installation shell, and the output end of the first cylinder points to the through hole. The output end of the first cylinder can push the pin shaft at the top of the pre-installation shell out of the pre-installation shell along the through hole. When this hinge automatic assembly device works, it controls the rotation unit to drive the leaf plate to rotate to the position of the pre-installation shell. At this time, the insertion hole of the leaf plate is opposite to the through hole, and the axis of the insertion hole is collinear with the axis of the through hole. Then, the first cylinder is driven. The output end of the first cylinder inserts into the pre-installation shell, pushes the pin shaft at the top of the pre-installation shell out of the pre-installation shell along the through hole, and makes the end of the pin shaft insert into the insertion hole of the leaf plate. Under the blocking of the limiting plate, the pin shaft can be inserted into the insertion hole of the leaf plate to achieve the assembly of the hinge.

[0004] The problem existing in the above hinge automatic assembly device during use is that there may be burrs on the inner wall of the insertion hole of the leaf plate. When the output end of the cylinder pushes the pin shaft at the top of the pre-installation shell out of the pre-installation shell along the through hole and pushes the pin shaft into the insertion hole of the leaf plate, due to the existence of burrs on the inner wall of the insertion hole, it will be difficult to insert the pin shaft. Summary of the Invention

[0005] The present invention provides a hinge assembly device, aiming to solve the problem that it is difficult to push the pin shaft into the insertion hole of the leaf plate existing in the above prior art hinge automatic assembly device during use.

[0006] The hinge assembly device of the present invention comprises an assembly platform and a push driving member, the assembly platform is provided with a push stop member, and also comprises a clamping mechanism, the clamping mechanism comprises a mounting seat and a striker shaft assembly, the push driving member can drive the mounting seat to move toward the push stop member, a mounting hole is opened at one end of the mounting seat close to the push stop member, the axial direction of the mounting hole is consistent with the driving direction of the push driving member, and the pin shaft is slidably inserted in the mounting hole; the striker shaft assembly is arranged in the mounting hole, the striker shaft assembly comprises a striker shaft elastic member, a striker shaft block, a force storage elastic member, a force storage extrusion block, a mounting block and a push block, the striker shaft block and the push block are slidably arranged in the mounting hole along the axial direction of the mounting hole, one end of the striker shaft elastic member is fixedly connected to the inner wall of the mounting hole, the other end of the striker shaft elastic member is fixedly connected to the striker shaft block, and the striker shaft block is close to the push The end face of the block forms an extrusion end face; the pushing block is located at the outer side of the impact shaft block, the mounting block is fixedly connected to the side of the pushing block close to the impact shaft block, the force storage extrusion block is arranged on the mounting block along the radial sliding of the mounting hole, the force storage extrusion block and the pushing block are spaced apart in the axial direction of the mounting hole, one end of the force storage elastic member is fixedly connected to the force storage extrusion block, and the other end is fixedly connected to the mounting block, the force storage extrusion block has an extrusion surface, and in the axial direction from the inside to the outside of the mounting hole, the distance from each point on the extrusion surface to the axis of the mounting hole gradually decreases; when the impact shaft block and the pushing block approach each other, the extrusion surface and the extrusion end face can be squeezed against each other, so that the impact shaft elastic member and the force storage elastic member are compressed, and the force storage extrusion block gradually moves away from the axis of the mounting hole, and when the extrusion surface is separated from the extrusion end face, the impact shaft block hits the pushing block under the drive of the impact shaft elastic member.

[0007] The beneficial effect is that when the hinge assembly device of the present invention is used, one end of the pin shaft is first installed in the mounting hole of the mounting seat, and then the two leaf plates of the hinge are spliced ​​and placed on the assembly platform, so that the leaf plates are located between the push-stop member and the pin shaft, and the insertion holes of the two leaf plates are coaxial with the pin shaft, and the end of the leaf plates away from the pin shaft abuts against the baffle. The push drive member is then controlled to drive the telescopic rod to extend outward, and the extrusion end face contacts the extrusion face, so that the push block contacts the pin shaft, thereby driving the pin shaft to be gradually inserted into the sockets of the two leaf plates. When there are burrs on the inner wall of the socket, the pin shaft will be blocked and cannot be inserted further. At this time, one end of the pin shaft located in the mounting hole will squeeze the push block to move toward the impact shaft block, and the extrusion face and the extrusion end face squeeze each other, thereby compressing the impact shaft elastic member and the force storage elastic member, and the force storage extrusion block gradually moves away from the axis of the mounting hole. When the extrusion face is separated from the extrusion end face, the impact shaft block hits the push block under the drive of the impact shaft elastic member, driving the push block and the pin shaft to move outward, and the extrusion face moves away from the extrusion end face. By applying an impact force for continued insertion to the pin shaft, the pin shaft can more easily break through the obstruction of the burr under the action of the impact force, thereby making it easier for the pin shaft to be inserted into the socket of the leaf plate.

[0008] Preferably, the clamping mechanism further includes a jaw assembly disposed within the mounting hole. The jaw assembly is capable of clamping the outer peripheral surface of the pin inserted into the mounting hole. When the axial force applied to the pin is greater than the maximum static frictional force acting on the pin by the jaw assembly in the axial direction, the pin can axially slide relative to the jaw assembly, and the maximum static frictional force acting on the pin by the jaw assembly is less than the impact force when the impact shaft block impacts on the push block.

[0009] Preferably, the jaw assembly includes a jaw elastic member and a clamping block. An installation groove extending radially along the hole wall of the mounting hole is provided. The clamping block is slidably disposed within the installation groove along the radial direction of the mounting hole. One end of the jaw elastic member is fixedly connected to the groove wall of the installation groove, and the other end of the jaw elastic member is fixedly connected to the clamping block. In the axial direction of the mounting hole, the clamping block is located outside the impact shaft block. When the jaw elastic member is in its natural state, a part of the clamping block extends out of the installation groove to form an overhanging portion. An extrusion inclined surface is provided on the side of the overhanging portion close to the orifice of the mounting hole. In the axial direction from the inside to the outside of the mounting hole, the distance from each point on the extrusion inclined surface to the axis of the mounting hole gradually increases.

[0010] Preferably, a pin clamping assembly is further provided on the assembly platform. The pin clamping assembly includes a clamping member and a force applying member. When one end of the pin passes through the insertion hole of the hinge leaf plate and extends outwards, the clamping member can clamp the part of the pin extending outwards under the action of the clamping force applied by the force applying member.

[0011] The beneficial effect is that after the pin is inserted into the insertion holes of the two leaf plates of the hinge, the pin clamping assembly can clamp the pin, thereby preventing the pin from being withdrawn together with the clamping mechanism when the push driving member drives the clamping mechanism to retract after the pin insertion is completed.

[0012] Preferably, the force applying member is a spring and the clamping member is a clamping plate. There are two clamping members, which are symmetrically arranged with respect to the vertical plane coplanar with the axis of the mounting hole. The two clamping members can slide towards or away from each other and are slidably disposed on the push stop member. A clamping space for clamping the pin is formed between the two clamping members. A clamping inclined surface is further provided on the side of the clamping member close to the clamping mechanism. In the axial direction from the inside to the outside of the mounting hole, the distance from each point on the clamping inclined surface to the axis of the mounting hole gradually decreases. There are two force applying members, and the two force applying members elastically connect the two clamping plates to the push stop member respectively.

[0013] Preferably, a rotation driving member is further included. The push driving member is fixedly disposed at the driving end of the rotation driving member. The output shaft of the rotation driving member is coaxial with the telescopic rod of the push driving member and the mounting hole. The rotation driving member can drive the push driving member to rotate around the axis of the mounting hole.

[0014] The beneficial effect is that the cooperation of the rotation driving member and the push driving member can drive the pin to rotate and be inserted into the insertion holes of the two leaf plates. The pin can be more easily inserted while rotating and inserting.

[0015] Preferably, a positioning mechanism is further included. The positioning mechanism includes a lifting driving member and a pressing member. The lifting driving member is in transmission connection with the pressing member, and the lifting driving member can drive the pressing member to lift and lower. A V-shaped groove is formed in the bottom surface of the pressing member, and the two groove walls of the V-shaped groove are symmetrically arranged with respect to a vertical plane coplanar with the axis of the mounting hole. The pressing member is located above the assembly platform.

[0016] The beneficial effect is that after the two vane plates of the hinge are placed in position, the lifting driving member drives the pressing member to descend, so that the V-shaped groove presses against the hinged part of the vane plate, which can prevent the vane plate from moving when the pin shaft is inserted.

[0017] Preferably, the pressing member includes a fixed part, a telescopic elastic member and a telescopic part. The fixed part is fixedly arranged at the driving end of the lifting driving member. The telescopic part is slidably arranged on the fixed part in the vertical direction. One end of the telescopic elastic member is fixedly connected with the fixed part, and the other end of the telescopic elastic member is fixedly connected with the telescopic part. When the telescopic elastic member is in a natural state, the bottom of the telescopic part is located below the fixed part, and the V-shaped groove is arranged on the bottom surface of the telescopic part.

[0018] The beneficial effect is that the pressing member is set to an elastically telescopic structure. When the lifting driving member drives the pressing member to descend, it can prevent the pressure of the pressing member on the vane plate from being too large and damaging the vane plate.

[0019] Preferably, the assembly platform is provided with a blanking hole, and the assembly platform is provided with a rotationality detection assembly. The rotationality detection assembly includes a first support slider, a first elastic member, a second support slider and a second elastic member. The first support slider is connected to the assembly platform through the first elastic member, and the second support slider is connected to the assembly platform through the second elastic member. The first support slider and the second support slider are symmetrically arranged at intervals with respect to a vertical plane coplanar with the axis of the mounting hole. The ends of the first support slider and the second support slider close to each other are located above the blanking hole. The first support slider and the second support slider are slidably arranged on the assembly platform in a direction perpendicular to their symmetry plane. The two ends of the first support slider and the second support slider close to each other are respectively used to support the two vane plates of the hinge. When the included angle between the two vane plates is 90 degrees, the two vane plates form a right triangle, and the maximum distance between the first support slider and the second support slider when they are far away from each other is equal to the length of the hypotenuse of the right triangle.

[0020] The beneficial effect is that the rotationality detection assembly can realize the rotationality detection of the assembled hinge and identify qualified and unqualified products with respect to rotationality.

[0021] Preferably, it further includes a cabinet body, the assembly platform is fixedly arranged on the upper surface of the cabinet body, and a blanking chute is further opened on the cabinet body. The inlet of the blanking chute is located below the blanking hole, and the hinges falling from the blanking hole can fall into the blanking chute and slide out from the outlet of the blanking chute.

[0022] The beneficial effects of the present invention are as follows: When the hinge assembly device of the present invention is in use, first install one end of the pin shaft in the installation hole of the mounting seat, and then splice the two leaf plates of the hinge and place them on the assembly platform, so that the leaf plates are located between the top-pushing stopper and the pin shaft, and the insertion holes of the two leaf plates are coaxial with the pin shaft, and the end of the leaf plate away from the pin shaft abuts against the baffle. Then, control the top-pushing driving member to drive the telescopic rod to extend outwards, the extrusion end face abuts against the extrusion surface, so that the top-pushing block abuts against the pin shaft, thereby driving the pin shaft to gradually insert into the insertion holes of the two leaf plates. When there are burrs on the inner wall of the insertion hole, the pin shaft will be blocked and cannot continue to be inserted. At this time, the end of the pin shaft located in the installation hole will squeeze the top-pushing block to move towards the impact shaft block, the extrusion surface and the extrusion end face are mutually extruded, and then the impact shaft elastic member and the energy storage elastic member are compressed, and the energy storage extrusion block gradually moves away from the axis of the installation hole. When the extrusion surface and the extrusion end face are separated, the impact shaft block impacts the top-pushing block under the drive of the impact shaft elastic member, driving the top-pushing block and the pin shaft to move outwards, the extrusion surface is away from the extrusion end face, and by applying an impact force for the pin shaft to continue to insert, the pin shaft can more easily break through the obstruction of the burr under the action of the impact force, so that the pin shaft can more easily insert into the insertion hole of the leaf plate. In addition, the rotation driving member and the top-pushing driving member cooperate to drive the pin shaft to rotate and insert into the insertion holes of the two leaf plates. The pin shaft can be more easily inserted while rotating and inserting. In addition, the rotationality detection assembly can realize the rotationality detection of the assembled hinge, and identify the qualified products and unqualified products with qualified rotationality.

[0035] The embodiments of the present invention will be described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0036] As Figures 1 to 10As shown, the hinge assembly device of the present invention includes an assembly platform 1, a rotary push drive mechanism 2, a clamping mechanism, a pin clamping assembly 3, a positioning mechanism, a rotation detection assembly and a cabinet 6. The assembly platform 1 is fixedly arranged on the cabinet 6, and the assembly platform 1 is used to carry the hinge 10 to be assembled. The rotary push drive mechanism 2 includes a push drive member (not shown in the figure) and a rotary drive member (not shown in the figure). Specifically, the rotary drive member is a motor, and the rotary drive member is fixedly arranged on the upper surface of the cabinet 6, and the output shaft of the rotary drive member is arranged in a horizontal state. The push drive member is an electric push rod, and the housing of the push drive member is fixedly arranged on the output shaft of the rotary drive member, and the telescopic rod 21 of the push drive member is coaxially arranged with the output shaft of the rotary drive member. The clamping mechanism is installed on the telescopic rod 21 of the push drive member, and the clamping mechanism is used to clamp the pin 102 to be assembled. The assembly platform 1 is provided with a push-stop member 11 for stopping the blade 101 of the hinge 10, and the push-stop member 11 is a baffle fixed on the assembly platform 1. When assembling the hinge 10, first install the pin 102 on the clamping mechanism, and then splice the two blades 101 of the hinge 10 and place them on the assembly platform 1, so that the blade 101 is located between the baffle and the pin 102, and the insertion holes of the two blades 101 are coaxial with the pin 102, and the end of the blade 101 away from the pin 102 abuts against the baffle. Then, the rotation drive member and the push drive member cooperate to drive the pin 102 to rotate and insert it into the insertion holes of the two blades 101.

[0037] like Figures 5 to 7 As shown, the clamping mechanism includes a mounting seat 8, a striker assembly and a clamping claw assembly 7. The mounting seat 8 is transmission-connected with the push-pushing driving member, and the push-pushing driving member can drive the mounting seat 8 to move toward the push-pushing stopper 11. Specifically, the mounting seat 8 is a cylindrical structure, and one end of the mounting seat 8 is fixed on the telescopic rod 21 of the push-pushing driving member. An end of the mounting seat 8 close to the push-pushing stopper 11 is provided with a mounting hole 81 extending along its axial direction, and the mounting hole 81 is a circular hole. The mounting hole 81 is coaxially arranged with the output shaft of the rotating driving member, and the pin 102 can be inserted in the mounting hole 81 along its axial sliding. The striker assembly is arranged in the mounting hole 81, and the striker assembly includes a striker elastic member 91, a striker block 92, a force storage elastic member 93, a force storage extrusion block 94, a mounting block 95 and a push-pushing block 96. The striker block 92 and the push-pushing block 96 are arranged in the mounting hole 81 along the axial sliding of the mounting hole 81. The impact shaft elastic member 91 is a spring, the length direction of the impact shaft elastic member 91 is parallel to the axial direction of the mounting hole 81, one end of the impact shaft elastic member 91 is fixedly connected to the inner wall of the mounting hole 81, and the other end of the impact shaft elastic member 91 is fixedly connected to the impact shaft block 92. The impact shaft block 92 is a cylindrical structure, the impact shaft block 92 is coaxially arranged with the mounting hole 81, and the end face of the impact shaft block 92 close to the push block 96 forms an extrusion end face.

[0038] like Figures 5 to 7As shown, the pushing block 96 is in the shape of a circular plate. The pushing block 96 is located outside the impact shaft block 92. The pushing block 96 is coaxially arranged with the mounting hole 81. The outer diameter of the pushing block 96 is equal to the inner diameter of the mounting hole 81. The pushing block 96 is slidably mounted in the mounting hole 81 along the axial direction of the mounting hole 81. The mounting block 95 is fixedly connected to the side of the pushing block 96 close to the impact shaft block 92. The energy storage squeezing block 94 is slidably arranged in the mounting block 95 along the radial direction of the mounting hole 81. The energy storage squeezing block 94 and the pushing block 96 are arranged at intervals in the axial direction of the mounting hole 81. Specifically, a sliding groove extending along the radial direction of the mounting hole 81 is formed in the mounting block 95. The energy storage squeezing block 94 is slidably mounted in the sliding groove.

[0039] As Figures 5 to 7 As shown, the energy storage elastic member 93 is a spring. The energy storage elastic member 93 is arranged in the sliding groove. The length direction of the energy storage elastic member 93 is along the radial direction of the mounting hole 81. One end of the energy storage elastic member 93 is fixedly connected to the energy storage squeezing block 94, and the other end is fixedly connected to the bottom wall of the sliding groove. The energy storage squeezing block 94 has a squeezing surface 941 for squeezing cooperation with the squeezing end surface. In the axial direction from the inside to the outside of the mounting hole 81, the distances from the points on the squeezing surface 941 to the axis of the mounting hole 81 gradually decrease. When the energy storage elastic member 93 is in the natural state, the squeezing surface 941 is located outside the sliding groove.

[0040] When there are burrs on the inner wall of the jacking hole, resulting in the pin 102 being blocked and unable to be inserted further, at this time, the end of the pin 102 located in the mounting hole 81 will push against the pushing block 96 and move towards the impact shaft block 92. The squeezing surface 941 and the squeezing end surface are squeezed against each other. The impact shaft elastic member 91 and the energy storage elastic member 93 are compressed. The energy storage squeezing block 94 gradually moves away from the axis of the mounting hole 81. When the squeezing surface 941 is separated from the squeezing end surface, the impact shaft elastic member 91 resets. The impact shaft block 92 impacts the pushing block 96 under the drive of the impact shaft elastic member 91, driving the pushing block 96 and the pin 102 to move outward, and making the squeezing surface 941 move away from the squeezing end surface, applying an impact force for the pin 102 to continue to insert. Under the action of the impact force, the pin 102 can more easily break through the obstruction of the burrs, so that the pin 102 can be smoothly inserted into the jacking hole of the vane 101.

[0041] As Figures 5 to 7As shown, the jaw assembly 7 is disposed in the mounting hole 81. The jaw assembly 7 can clamp the outer peripheral surface of the pin shaft 102 inserted into the mounting hole 81 and rotate with the pin shaft 102. When the axial force applied to the pin shaft 102 is greater than the maximum axial static friction force exerted by the jaw assembly 7 on the pin shaft 102, the pin shaft 102 can axially slide relative to the jaw assembly 7, and the maximum axial static friction force exerted by the jaw assembly 7 on the pin shaft 102 is less than the impact force when the impact shaft block 92 impacts on the push block 96. The jaw assembly 7 includes a jaw elastic member 71 and a jaw block 72. An installation groove extending in the radial direction thereof is formed in the hole wall of the mounting hole 81. The jaw block 72 is slidably disposed in the installation groove along the radial direction of the mounting hole 81. In the axial direction of the mounting hole 81, the jaw block 72 is located outside the impact shaft block 92. The jaw elastic member 71 is a spring. The jaw elastic member 71 is disposed in the installation groove. One end of the jaw elastic member 71 is fixedly connected to the bottom wall of the installation groove, and the other end of the jaw elastic member 71 is fixedly connected to the jaw block 72. When the jaw elastic member 71 is in the natural state, a part of the jaw block 72 extends out of the installation groove to form an overhanging portion 721. An extrusion inclined surface 722 is provided on the side of the overhanging portion 721 close to the orifice of the mounting hole 81. In the axial direction from the inside to the outside of the mounting hole 81, the distance from each point on the extrusion inclined surface 722 to the axis of the mounting hole 81 gradually increases. When the pin shaft 102 is inserted into the mounting hole 81, the end of the pin shaft 102 will press against the extrusion inclined surface 722, thereby squeezing the overhanging portion 721 of the jaw block 72 into the installation groove, and then the jaw block 72 clamps the outer peripheral surface of the pin shaft 102 under the elastic force of the jaw elastic member 71.

[0042] As Figures 2 to 4As shown, the pin clamping assembly 3 includes a clamping member 31 and a force applying member 32. When one end of the pin 102 passes through the insertion hole of the hinge 10 vane 101 and extends outwards, the clamping member 31 can clamp the part of the pin 102 extending outwards under the action of the clamping force applied by the force applying member 32. Specifically, the force applying member 32 is a spring, and the clamping member 31 is a clamping plate. There are two clamping members 31, and the two clamping members 31 are symmetrically arranged with respect to the vertical plane coplanar with the axis of the mounting hole 81. The two clamping members 31 can slide close to or away from each other on the top pushing and stopping member 11, and a clamping space for clamping the pin 102 is formed between the two clamping members 31. A clamping inclined surface 311 is further provided on the side of the clamping member 31 close to the clamping mechanism. In the axial direction of the mounting hole 81 from inside to outside, the distance from each point on the clamping inclined surface 311 to the axis of the mounting hole 81 gradually decreases. There are two force applying members 32, and the two force applying members 32 elastically connect the two clamping plates to the top pushing and stopping member 11 respectively. The length directions of the two force applying members 32 are perpendicular to the vertical plane coplanar with the axis of the mounting hole 81. The top pushing and stopping member 11 is slidably arranged on the assembly platform 1 along the axial direction of the mounting hole 81 through a top pushing elastic member 14. Specifically, the top pushing elastic member 14 is a spring, the length direction of the top pushing elastic member 14 is consistent with the axial direction of the mounting hole 81, one end of the top pushing elastic member 14 is fixed on the assembly platform 1, and the other end of the top pushing elastic member 14 is fixed on the top pushing and stopping member 11.

[0043] When one end of the pin 102 passes through the insertion hole of the hinge 10 vane 101 and extends into the clamping space of the two clamping members 31, the end of the pin 102 will squeeze the clamping inclined surfaces 311 of the two clamping members 31, thereby driving the two clamping members 31 to move away from each other. The two clamping members 31 clamp the pin 102, which can prevent the pin 102 from being withdrawn together with the clamping mechanism when the top pushing driving member drives the clamping mechanism to retreat after the pin 102 is inserted.

[0044] As Figure 1 , Figures 8 to 10As shown in the figure, the positioning mechanism includes a lifting drive member 41 and a pressing member 42. The lifting drive member 41 is in transmission connection with the pressing member 42, and the lifting drive member 41 can drive the pressing member 42 to lift and lower. Specifically, the lifting drive member 41 is a cylinder, the telescopic rod of the lifting drive member 41 is arranged vertically downward, the lifting drive member 41 is fixed on the cabinet body 6 through a mounting bracket 61, and the lifting drive member 41 is located above the assembly platform 1. The pressing member 42 is located above the assembly platform 1. Specifically, the pressing member 42 includes a fixing portion 421, a telescopic elastic member 422 and a telescopic portion 423. The fixing portion 421 is fixedly arranged on the telescopic rod of the lifting drive member 41. A sliding groove extending in the vertical direction is formed at the bottom of the fixing portion 421. The telescopic portion 423 is slidably arranged in the sliding groove in the vertical direction. The telescopic elastic member 422 is a spring. The telescopic elastic member 422 is arranged in the sliding groove. One end of the telescopic elastic member 422 is fixedly connected to the bottom wall of the sliding groove, and the other end of the telescopic elastic member 422 is fixedly connected to the upper end surface of the telescopic portion 423. When the telescopic elastic member 422 is in a natural state, the bottom of the telescopic portion 423 extends out of the sliding groove and is located below the fixing portion 421. A V-shaped groove 424 is formed on the bottom surface of the telescopic portion 423, and the two groove walls of the V-shaped groove 424 are symmetrically arranged with respect to a vertical plane coplanar with the axis of the mounting hole 81. After the two leaf plates 101 of the hinge 10 are placed in position, the lifting drive member 41 is used to drive the pressing member 42 to descend, so that the V-shaped groove 424 presses against the hinged portion of the leaf plate 101, which can prevent the leaf plate 101 from moving when the pin shaft 102 is inserted.

[0045] As Figure 1 , Figures 2 to 4As shown in the figure, the assembly platform 1 is fixedly arranged on the upper surface of the cabinet body 6, and the assembly platform 1 is provided with a blanking hole 12 that penetrates up and down. The rotationality detection component is arranged on the assembly platform 1, and the rotationality detection component includes a first support slider 51, a first elastic member 52, a second support slider 53, and a second elastic member 54. The first elastic member 52 is a spring, and the length direction of the first elastic member 52 is perpendicular to the vertical plane coplanar with the axis of the mounting hole 81. One end of the first elastic member 52 is fixedly connected to the assembly platform 1, and the other end of the first elastic member 52 is fixedly connected to the first support slider 51. The second elastic member 54 is a spring, and the length direction of the second elastic member 54 is perpendicular to the vertical plane coplanar with the axis of the mounting hole 81. One end of the second elastic member 54 is fixedly connected to the assembly platform 1, and the other end of the second elastic member 54 is fixedly connected to the second support slider 53. When the first elastic member 52 and the second elastic member 54 are in the natural state, the first support slider 51 and the second support slider 53 are symmetrically spaced apart with respect to the vertical plane coplanar with the axis of the mounting hole 81. The assembly platform 1 is provided with a guiding chute 13, and the first support slider 51 and the second support slider 53 are slidably arranged in the guiding chute 13 of the assembly platform 1 in a direction perpendicular to the symmetry plane of the two. One end of the first support slider 51 close to the second support slider 53 is located above the blanking hole 12, and one end of the second support slider 53 close to the first support slider 51 is located above the blanking hole 12. Two end portions of the first support slider 51 and the second support slider 53 that are close to each other are respectively used to support the two leaf plates 101 of the hinge 10. When the included angle between the two leaf plates 101 is 90 degrees, the two leaf plates 101 form a right triangle, and when the first support slider 51 and the second support slider 53 move away from each other, the maximum distance between them is equal to the length of the hypotenuse of the right triangle.

[0046] After the pin shaft 102 is inserted, control the lifting driving member 41 to drive the pressing member 42 to continue to descend. At this time, if the rotationality of the assembled hinge 10 meets the requirements, then the hinged part of the hinge 10 will be pushed by the pressing member 42 and move downward from the gap between the first support slider 51 and the second support slider 53. At this time, the two leaf plates 101 will rotate relative to each other, and the included angle between the two leaf plates 101 will gradually decrease until the hinge 10 falls from the gap; during the process of the included angle between the two leaf plates 101 gradually decreasing, the leaf plate 101 will squeeze the support slider supported by it, causing the first support slider 51 and the second support slider 53 to move away from each other, and the distance between them will gradually increase. The limitation of the maximum distance between the first support slider 51 and the second support slider 53 can prevent the hinge 10 with the relative rotation range of the two leaf plates 101 less than 90 degrees from falling. The hinge 10 that can fall is qualified, and the hinge 10 that cannot fall is unqualified, so as to realize the rotationality detection of the assembled hinge 10 and identify qualified products and unqualified products.

[0047] A blanking chute (not shown in the figure) is also provided on the cabinet body 6. The inlet of the blanking chute is located below the blanking hole 12. The hinge 10 falling from the blanking hole 12 can fall into the blanking chute and slide out from the outlet of the blanking chute.

[0048] The implementation principle of the hinge assembly device according to the embodiment of the present invention is as follows: When in use, first insert one end of the pin shaft 102 into the mounting hole 81 of the mounting seat 8, and then splice the two leaf plates 101 of the hinge 10 and place them on the assembly platform 1. The leaf plates 101 are located between the top-pushing stopper 11 and the pin shaft 102, and the insertion holes of the two leaf plates 101 are coaxial with the pin shaft 102. The end of the leaf plate 101 away from the pin shaft 102 abuts against the baffle. Then, start the rotation driving member and the top-pushing driving member. The top-pushing driving member drives the telescopic rod to extend outwards, so that the extrusion end face abuts against the extrusion surface 941, and the top-pushing block 96 abuts against the pin shaft 102, and then drives the pin shaft 102 to gradually rotate and insert into the insertion holes of the two leaf plates 101. When there are burrs on the inner wall of the insertion hole, the pin shaft 102 will be blocked and cannot continue to be inserted. At this time, the end of the pin shaft 102 located in the mounting hole 81 presses the top-pushing block 96 towards the impact shaft block 92. The extrusion surface 941 and the extrusion end face are mutually extruded, so that the impact shaft elastic member 91 and the energy storage elastic member 93 are compressed, and the energy storage extrusion block 94 gradually moves away from the axis of the mounting hole 81. When the extrusion surface 941 and the extrusion end face are separated, the impact shaft block 92 impacts the top-pushing block 96 under the drive of the impact shaft elastic member 91, drives the top-pushing block 96 and the pin shaft 102 to move outwards, so that the extrusion surface 941 is away from the extrusion end face, and by applying an impact force to the pin shaft 102, the pin shaft 102 can more easily break through the blockage of the burr under the action of the impact force, so that the pin shaft 102 can more easily insert into the insertion hole of the leaf plate 101. After the pin shaft 102 is inserted, control the lifting driving member 41 to drive the pressing member 42 to continue to descend. The hinged part of the hinge 10 will be pushed by the pressing member 42 and move downwards from the gap between the first support slider 51 and the second support slider 53. At this time, the two leaf plates 101 will rotate relatively, and the included angle between the two leaf plates 101 gradually decreases. During the process of the gradual decrease of the included angle between the two leaf plates 101, the leaf plate 101 will press the support slider supporting it below, so that the first support slider 51 and the second support slider 53 move away from each other. The hinge 10 with the relative rotation range of the two leaf plates 101 less than 90 degrees cannot fall off. The hinge 10 that can fall off is qualified, and the hinge 10 that cannot fall off is unqualified, realizing the rotation detection of the assembled hinge 10 and identifying qualified products and unqualified products.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
