Description

Technical Field

[0001] The present application relates to the field of refrigerator door panel manufacturing, and in particular to a refrigerator door frame and an integrated assembly and testing machine. Background Art

[0002] The refrigerator door panel is usually composed of a door frame as the main body, and the refrigerator door frame is a plastic part produced by injection molding. Due to the requirements of functionality and aesthetics, decorative strips and bar magnets need to be installed on the refrigerator door frame.

[0003] The existing process fixes the decorative strips to the refrigerator door frame with bolts and installs the magnets by gluing. When installing the decorative strips, the worker places the refrigerator door frame face up on the operating table, aligns the decorative strips, and then tightens the screws with a screwdriver; when installing the magnets, the worker manually flips the refrigerator door frame so that its side faces up, fixes the refrigerator door frame with one hand, and uses the glue gun with the other hand to dispense glue, pressing the magnet into the designated position before the glue solidifies. After the installation is completed, the refrigerator door frame is moved to the testing equipment for testing to check whether the decorative strips and magnets are installed in place and whether the magnetic poles of the magnets are correct.

[0004] However, bolt installation will destroy the beauty of the decorative strips, and the metal is prone to rust during use, affecting the stability of the decorative strips; the low temperature inside the refrigerator can easily cause the adhesive to lose its viscosity and the magnet to fall off. In addition, the installation and inspection process requires operators to manually operate step by step, which is inefficient. Utility Model Content

[0005] In order to improve the stability and efficiency of the installation of decorative strips and magnets, the present application provides a refrigerator door frame and an all-in-one assembly detection machine.

[0006] In the first aspect, the present application provides a refrigerator door frame adopting the following technical solution:

[0007] A refrigerator door frame comprises a door frame body and a decorative strip, wherein: the decorative strip is provided with a snap assembly cooperating with the door frame body; the door frame body is provided with a receiving groove for installing a magnet, and a clamping assembly is provided in the receiving groove.

[0008] By adopting the above technical solution, the operator installs the decorative strip with the door frame body through the buckle assembly, and then inserts one end of the magnet into the receiving groove from the opening of the receiving groove. During the insertion process, the resistance of the clamping assembly must be overcome. The clamping assembly fixes the magnet in the receiving groove and it is difficult to dislodge. Compared with the prior art that installs decorative strips and magnets by bolts and adhesives respectively, the present application adopts a buckling method to improve the stability of the installation of decorative strips and magnets. In addition, the buckle assembly and the clamping assembly can assist in the alignment of the decorative strip and the magnet, thereby improving the installation efficiency.

[0009] Optionally, the snap assembly includes a snap block and a guide rail; the snap block is arranged on the side wall of the long side of the decorative strip, and the door frame body is provided with a snap groove that cooperates with the snap block; the decorative strip is provided with a wing plate, and the door frame body is provided with a step corresponding to the wing plate, the guide rail is provided on the wing plate on the short side of the decorative strip, and the step of the door frame body is provided with a track corresponding to the guide rail, and the length direction of the guide rail is parallel to the moving direction of the decorative strip when it is installed.

[0010] Optionally, the buckle assembly further includes a protrusion, which is arranged on the wing plate of the long side of the decorative strip, and a concave block cooperating with the protrusion is arranged on the step of the door frame body.

[0011] By adopting the above technical solution, the operator holds the decorative strip and inserts the guide rail from the opening of the track. At this time, the buckle block is aligned with the buckle groove, and the protrusion is also aligned with the concave block. The decorative strip is pushed along the length direction of the guide rail until the buckle block and the side wall of the door frame body close to the buckle groove are elastically deformed, so that the buckle block is stuck in the buckle groove and difficult to escape. The decorative strip is difficult to move in the width direction, which improves the installation stability of the decorative strip in the width direction. At this time, the protrusion is also inserted in the concave block, and the decorative strip is difficult to move in the length direction, which improves the installation stability of the decorative strip in the length direction. During the installation process, the guide rail and the track are used to assist the alignment of the buckle block and the protrusion, thereby improving the efficiency of installation.

[0012] Optionally, a accommodating block is installed on the door frame body, the accommodating groove is arranged in the accommodating block, and the clamping assembly includes an elastic plate and a convex strip; the elastic plate is installed in the accommodating groove, and the side wall on one side of the elastic plate is connected to the inner wall of the accommodating groove, and the side wall on the other side is freely arranged; the convex strip is arranged in the accommodating groove, and the side wall on one side of the convex strip is connected to the inner wall of the accommodating groove, and the side wall on the other side is freely arranged, and the free end of the convex strip is arranged toward the elastic plate.

[0013] By adopting the above technical solution, the free end of the convex strip presses the magnet against the elastic plate, the side wall of the elastic plate close to the convex strip is in contact with the side wall of the magnet, and the convex strip and the elastic plate clamp the magnet from both sides, so that the magnet is difficult to move by itself. The stability of the magnet installation is improved. The convex strip can guide the installation of the magnet, assist the installation of the magnet, and improve the installation efficiency. The setting of the convex strip and the elastic plate also has a certain shock absorption ability. If the door is closed too hard in subsequent use, the convex strip and the elastic plate can absorb part of the impact force, reducing the possibility of the magnet falling off and breaking.

[0014] In the second aspect, the present application also discloses an assembly and detection integrated machine:

[0015] An integrated assembly and detection machine includes a workbench, on which a fixture is arranged, and on which a first mounting plate for mounting a decorative strip and a second mounting plate for mounting a magnet are arranged, wherein the first mounting plate and the second mounting plate both slide in cooperation with the workbench; and a detection component for detecting the magnetic poles of the magnet is also arranged on the workbench.

[0016] By adopting the above technical solution, the operator pre-assembles the decorative strips and magnets, and clamps the door frame body on the jig, and the detection piece is aligned with the bottom of the receiving groove. The first mounting plate pushes the decorative strip along the guide rail until the buckle block is inserted into the buckle groove, and the protrusion is also inserted into the concave block, and the decorative strip is installed. The second mounting plate pushes the magnet down in the vertical direction until the bottom of the receiving groove, and the magnet is installed. The detection piece detects the magnetic pole of the magnet at the bottom of the receiving groove. After the detection is completed, the operator takes away the door frame body for storage. During the whole process, the operator only needs to manually pre-install the decorative strips and magnets, which simplifies the subsequent laborious installation process and improves the installation efficiency. The force application process of the first mounting plate on the decorative strip is more uniform than manual knocking, to ensure that each buckle is installed in place, improving the stability of the decorative strip installation and the quality of the finished product. The thrust of the second mounting plate on the magnet is also more uniform, reducing the occurrence of magnet breakage caused by manual installation.

[0017] Optionally, the fixture includes a first module group and a second module group; the first module group is detachably connected to the workbench; a movable table is movably provided on the workbench, and the second module group is detachably connected to the movable table.

[0018] By adopting the above technical solution, before production, the operator pre-installs different second module groups on multiple movable tables, and then selects a suitable second module group according to the specifications of the door frame body to be installed. The first module group or the second module group assists the door frame body to achieve rapid positioning. When the specifications of the door frame change, the operator only needs to disassemble the movable table to remove the second module group, and install the adapted second module group on the workbench through the movable table, so as to achieve rapid replacement of the second module group, save replacement and production time, and improve production efficiency.

[0020] By adopting the above technical solution, the straightening cylinder is restricted by the locking member in the initial state. When the second mounting plate begins to descend, the trigger rod triggers the locking member to unlock, and the elastic member lifts the straightening cylinder. The straightening cylinder pushes the crooked magnet from bottom to top to restore it to vertical. The equipment corrects the magnet by itself, and improves the efficiency of magnet installation by eliminating the manual correction process, thereby improving the efficiency of production; it can also increase the tolerance of the equipment to manual pre-installation. The second mounting plate continues to descend, pushing the magnet and the straightening cylinder to descend synchronously. During the descent, the straightening cylinder controls the magnet to maintain a vertical state, reducing the occurrence of its breakage due to the crooked magnet during the installation process. When the second mounting plate descends to its lowest point, the straightening cylinder is locked by the locking member again, and the elastic member is in a compressed state. The downward movement of the straightening cylinder is driven by the second mounting plate and at the same time stores force for the elastic member. There is no need to add additional cylinders, which reduces the cost of the equipment.

[0021] Optionally, the locking member includes a locking rod, a torsion spring, an abutment column and an unlocking column. The middle part of the locking rod is rotatably connected to the workbench, one end of the torsion spring is connected to the locking rod, and the other end is connected to the workbench; the abutment column and the unlocking column are respectively installed at both ends of the locking rod, the abutment column can be abutted against the straightening cylinder, and a ball head is provided at the end of the trigger rod away from the second mounting plate, and the ball head can be abutted against the unlocking column.

[0022] By adopting the above technical solution, the setting of the locking member can realize the locking and unlocking of the straightening cylinder, and the locking and unlocking processes are linked by the second mounting plate, without the need to set up additional power parts such as cylinders, thus saving equipment costs.

During the insertion process, the resistance of the clamping assembly must be overcome. The clamping assembly fixes the magnet in the receiving groove and it is difficult to dislodge. Compared with the prior art that installs decorative strips and magnets by bolts and adhesives respectively, this application adopts a buckling method to improve the stability of the installation of decorative strips and magnets. In addition, the buckle assembly and the clamping assembly can assist in the alignment of the decorative strips and magnets, thereby improving installation efficiency;

[0025] 2. The operator pre-assembles the decorative strips and magnets, and clamps the door frame body on the jig. At this time, the detection piece is aligned with the bottom of the receiving groove. The first mounting plate pushes the decorative strip along the guide rail until the buckle block is inserted into the buckle groove, and the protrusion is also inserted into the recessed block, and the decorative strip is installed. The second mounting plate pushes the magnet down in the vertical direction until it reaches the bottom of the receiving groove, and the magnet is installed.

The equipment corrects the magnet by itself, which improves the efficiency of magnet installation by eliminating the manual correction process, thereby improving the efficiency of production; it can also increase the tolerance of the equipment to manual pre-installation. The second mounting plate continues to descend, pushing the magnet and the straightening cylinder to descend synchronously. During the descent, the straightening cylinder controls the magnet to remain in a vertical state, reducing the occurrence of magnet breakage caused by crooked magnets during installation.

[0037] The operator installs the decorative strip 2 by buckling it with the door frame body 1 through the buckle assembly 3, and then inserts one end of the magnet into the receiving groove 14 from the opening of the receiving groove 14. During the insertion process, the resistance of the clamping assembly 4 must be overcome. The clamping assembly 4 fixes the magnet in the receiving groove 14 and it is difficult to dislodge. Compared with the prior art that installs the decorative strip 2 and the magnet by bolts and adhesives respectively, the present application adopts a buckling method to improve the stability of the installation of the decorative strip 2 and the magnet. In addition, the buckle assembly 3 and the clamping assembly 4 can assist in the alignment of the decorative strip 2 and the magnet, thereby improving the installation efficiency.

[0038] Reference Figure 1 and Figure 2The buckle assembly 3 includes a buckle block 31, a protrusion 33 and a guide rail 32, and the buckle block 31, the protrusion 33 and the guide rail 32 are all integrally formed on the decorative strip 2. The buckle block 31 is arranged on the side wall of one of the long sides of the decorative strip 2, and a buckle groove 11 is provided on the door frame body 1 to cooperate with the buckle block 31, and the buckle block 31 is interference-fitted with the inner wall of the buckle groove 11. The number of the buckle blocks 31 is set to be multiple. In this embodiment, a total of four buckle blocks 31 are arranged on the decorative strip 2, and the four buckle blocks 31 are arranged in an array along the length direction of the decorative strip 2, and four buckle grooves 11 are correspondingly provided on the door frame body 1.

[0039] The side wall of the decorative strip 2 is provided with a wing plate, and the side wall where the buckle block 31 is located is not provided with a wing plate, and the wing plate is integrally formed with the decorative strip 2. The door frame body 1 is provided with a step corresponding to the wing plate. The guide rail 32 is provided on the wing plate of the short side of the decorative strip 2. In this embodiment, the guide rail 32 is provided on the wing plates of the two short sides of the decorative strip 2. The step of the door frame body 1 is provided with a track 12 corresponding to the guide rail 32, and the guide rail 32 can be inserted into the track 12, and the peripheral wall of the guide rail 32 is slidably matched with the inner wall of the track 12. The length direction of the guide rail 32 is parallel to the moving direction of the decorative strip 2 when it is installed.

[0040] The protrusion 33 is arranged on the long side wing plate of the decorative strip 2 away from the buckle block 31, and the protrusion 33 is formed integrally with the decorative strip 2. A concave block 13 cooperating with the protrusion 33 is arranged on the step of the door frame body 1, and the protrusion 33 can be inserted into the concave block 13; the concave block 13 is formed integrally with the door frame body 1. The number of the protrusions 33 is set to be multiple. In this embodiment, a total of three protrusions 33 are arranged on the decorative strip 2, and the three protrusions 33 are arranged in an array along the length direction of the decorative strip 2, and three concave blocks 13 are correspondingly arranged on the door frame body 1.

[0041] The operator holds the decorative strip 2 and controls it to approach the door frame body 1, so that the guide rail 32 on the wing plate of the decorative strip 2 is inserted into the track 12 from the opening of the track 12. At this time, the buckle block 31 is aligned with the buckle groove 11, and the protrusion 33 is also aligned with the concave block 13. The decorative strip 2 is pushed along the length direction of the guide rail 32 until the buckle block 31 and the side wall of the door frame body 1 close to the buckle groove 11 are elastically deformed, so that the buckle block 31 is stuck in the buckle groove 11 and is difficult to escape. The decorative strip 2 is difficult to move in its width direction, which improves the installation stability of the decorative strip 2 in the width direction. At this time, the protrusion 33 is also inserted in the concave block 13, and the decorative strip 2 is difficult to move in its length direction, which improves the installation stability of the decorative strip 2 in the length direction. During the installation process, the guide rail 32 and the track 12 are used to assist the alignment of the buckle block 31 and the protrusion 33, thereby improving the efficiency of installation.

[0042] Reference Figure 3The clamping assembly 4 includes an elastic plate 41 and a convex strip 42, and both the elastic plate 41 and the convex strip 42 are arranged in the receiving groove 14. A notch is provided in the side wall of the door frame body 1 near the receiving groove 14, and the elastic plate 41 is arranged in the notch. The length direction of the elastic plate 41 is arranged parallel to the height direction of the receiving groove 14, and the elastic plate 41 is integrally formed on the door frame body 1. The side wall on one side of the elastic plate 41 is connected to the side wall of the door frame body 1 located at the notch, and the other side wall of the elastic plate 41 is freely arranged. The convex strip 42 is located on the side of the receiving groove 14 away from the elastic plate 41, and the length direction of the convex strip 42 is arranged parallel to the height direction of the receiving groove 14, and the convex strip 42 is integrally formed on the receiving block 15. The side wall on one side of the convex strip 42 is connected to the inner wall of the receiving groove 14, and the other side wall is freely arranged.

[0043] The magnet is installed between the protruding strip 42 and the elastic plate 41. The free end of the protruding strip 42 can abut against the magnet. The side wall of the elastic plate 41 close to the protruding strip 42 can also abut against the magnet. The protruding strip 42 and the elastic plate 41 clamp the magnet together.

[0044] The operator inserts the magnet from the opening of the receiving groove 14, and applies force to cause the elastic plate 41 to undergo elastic deformation, and the elastic plate 41 tends to rotate from the receiving groove 14 to the notch. When the magnet is completely inserted into the receiving groove 14, the free end of the convex strip 42 presses the magnet against the elastic plate 41, and the side wall of the elastic plate 41 close to the convex strip 42 is in contact with the side wall of the magnet. The convex strip 42 and the elastic plate 41 clamp the magnet together from both sides, and the magnet is difficult to move by itself. Improve the stability of the magnet installation. And the convex strip 42 can guide the installation of the magnet, assist the installation of the magnet, and improve the installation efficiency. The setting of the convex strip 42 and the elastic plate 41 also has a certain shock absorption capacity. If the door is closed too hard in subsequent use, the convex strip 42 and the elastic plate 41 can absorb part of the impact force and reduce the possibility of the magnet falling off and breaking.

[0045] The implementation principle of a refrigerator door frame of the present application embodiment is as follows: the operator aligns the decorative strip 2 with the door frame body 1 through the guide rail 32 and the track 12, and pushes the decorative strip 2 along the length direction of the guide rail 32 until the buckle block 31 is locked in the buckle groove 11, and the protrusion 33 is also inserted in the concave block 13. The decorative strip 2 is difficult to move in both the length and width directions, which improves the stability and efficiency of the installation of the decorative strip 2. The operator then inserts the magnet into the accommodating groove 14 from the opening thereof, and the protrusion 42 and the elastic plate 41 clamp the magnet from both sides, making it difficult for the magnet to move, which improves the stability and efficiency of the magnet installation.

[0046] Since the decorative strip 2 and the magnet are both installed by snap-fitting, the snap-fitting structure is provided with interference fit to improve stability, and sometimes the operator is required to use a leather hammer to assist the snap-fitting. Therefore, the embodiment of the present application also discloses an all-in-one assembly and detection machine to assist in the installation of the decorative strip 2 and the magnet.

[0047] An integrated assembly and detection machine adopts the following technical solution.

[0048] Example 1

[0049] Reference Figure 4 , an assembly and detection integrated machine includes a workbench 5, on which a jig 6 is arranged, and a door frame body 1 can be clamped on the jig 6. A first mounting plate 71 for mounting a decorative strip 2 and a second mounting plate 72 for mounting a magnet are arranged on the workbench 5, and the first mounting plate 71 and the second mounting plate 72 are both slidably matched with the workbench 5. In this embodiment, the first mounting plate 71 and the second mounting plate 72 are driven by cylinders respectively. According to the installation position and installation direction of the decorative plate and the magnet, the first mounting plate 71 is arranged in the horizontal plane where the jig 6 is located, and the cylinder drives the first mounting plate 71 to approach or move away from the door frame body 1 placed on the jig 6 in the horizontal direction; the second mounting plate 72 is arranged above the jig 6, and the cylinder drives the second mounting plate 72 to approach or move away from the door frame body 1 placed on the jig 6 in the vertical direction. A detection member 8 for detecting the magnetic pole of the magnet is also arranged on the workbench 5, and the detection member 8 is located next to the jig 6. The structure of the detection member 8 is the existing technology, and the detection member 8 detects the magnetic pole across the side wall of the accommodation block 15.

[0050] The operator clamps the decorative strip 2 on the door frame body 1 through the guide rail 32 and the track 12, but there is no need to press it until it is completely engaged; then insert the end of the magnet into the receiving groove 14, but there is no need to press it to the bottom. The pre-assembly of the door frame body 1 is completed. The pre-assembled door frame body 1 is clamped on the jig 6, and the detection piece 8 is aligned with the bottom of the receiving groove 14. The first mounting plate 71 and the second mounting plate 72 are started at the same time, and the first mounting plate 71 approaches the door frame body 1 in the horizontal direction. The first mounting plate 71 first contacts the edge of the decorative strip 2 protruding from the door frame body 1, and pushes the decorative strip 2 along the length direction of the guide rail 32. The door frame body 1 is blocked by the jig 6 and is difficult to move until the buckle block 31 is inserted into the buckle groove 11, and the protrusion 33 is also inserted into the recessed block 13, and the decorative strip 2 is installed. The second mounting plate 72 descends vertically, and the second mounting plate 72 first contacts the top of the magnet and pushes the magnet down in the vertical direction. The door frame body 1 is blocked by the workbench 5 and is difficult to move until the magnet is pushed to the bottom of the receiving groove 14. The magnet is installed. The detection member 8 detects the magnetic pole of the magnet at the bottom of the receiving groove 14. After the detection is completed, the operator takes away the door frame body 1 for storage.

[0051] During the whole process, the operator only needs to manually pre-install the decorative strip 2 and the magnet, which simplifies the subsequent laborious installation process and improves the installation efficiency. The first mounting plate 71 applies force to the decorative strip 2 more evenly than manual tapping, ensuring that each buckle is installed in place, improving the stability of the installation of the decorative strip 2 and the quality of the finished product. The second mounting plate 72 also applies more even force to the magnet, reducing the occurrence of magnet breakage caused by manual installation.

[0052] Reference Figure 4 and Figure 5 The jig 6 includes a first module group 61 and a second module group 62 to adapt to door frame bodies 1 of different specifications. The first module group 61 and the second module group 62 each include a plurality of positioning blocks, and the plurality of positioning blocks surround the door frame body 1 from all sides. The top of the positioning block is provided with a smooth slope to assist in rapid positioning of the door frame body 1. The positioning block of the first module group 61 is connected to the workbench 5 by bolts.

[0053] The workbench 5 is provided with a gap in the center, the gap is located between the multiple positioning blocks of the first module group 61, and a movable platform 51 is provided in the gap, and the movable platform 51 is connected to the workbench 5 by bolts. The positioning blocks of the second module group 62 are connected to the movable platform 51 by bolts.

[0054] Before production, the operator pre-installs different second module groups 62 on multiple movable tables 51, and then selects a suitable second module group 62 according to the specifications of the door frame body 1 to be installed. In this embodiment, the first module group 61 is compatible with most door frame bodies 1. After the equipment is debugged, production is carried out, and the operator aligns the door frame body 1 with the first module group 61 or the second module group 62, and the first module group 61 or the second module group 62 assists the door frame body 1 to achieve rapid positioning. When the specifications of the refrigerator door frame change, the operator only needs to disassemble the movable table 51 to remove the second module group 62, and then select the adapted second module group 62, and install the adapted second module group 62 on the workbench 5 through the movable table 51, so as to achieve rapid replacement of the second module group 62, save replacement and production time, and improve production efficiency.

[0055] The implementation principle of Example 1 is as follows: the operator pre-installs the decorative strip 2 and the magnet on the door frame body 1, and clamps the door frame body 1 on the first module group 61 or the second module group 62. The first mounting plate 71 pushes the decorative strip 2 to be clamped and fixed, and the second mounting plate 72 pushes the magnet to be clamped and fixed, and the detection member 8 detects the magnetic pole. After the installation is completed, the operator takes away the refrigerator door frame for storage. When the specifications of the refrigerator door frame change, the operator removes the movable table 51 and replaces the movable table 51 with the second module group 62 with matching specifications. The stability and efficiency of the installation of the decorative strip 2 and the magnet are improved.

[0056] Example 2

[0057] Reference Figure 6 and Figure 7 Since the magnet is pre-installed manually, the magnet may be skewed, and the second mounting plate 72 pushing the skewed magnet may easily cause the magnet to break, so a straightening cylinder 91 is also provided on the workbench 5. The straightening cylinder 91 is surrounded by the outer side of the accommodating block 15, and can reciprocate in the vertical direction along the outer wall of the accommodating block 15. An elastic member 92 is provided on the workbench 5, and the straightening cylinder 91 is connected to the workbench 5 through the elastic member 92. The straightening cylinder 91 can be higher than the accommodating block 15 and contact the side wall of the magnet, and the bottom wall of the second mounting plate 72 can be against the top wall of the straightening cylinder 91. A circular arc chamfer is provided at the edge of the top wall of the straightening cylinder 91.

[0058] A locking member 93 is provided on the side of the elastic member 92 away from the straightening cylinder 91. The locking member 93 is rotatably mounted on the workbench 5. The locking member 93 can limit the movement of the straightening cylinder 91 and put the elastic member 92 in a compressed state. A trigger rod 94 is provided on the second mounting plate 72. The trigger rod 94 can trigger the locking member 93 to release the restriction on the straightening cylinder 91. A clearance hole corresponding to the trigger rod 94 is provided on the workbench 5.

[0059] In the initial state, the straightening cylinder 91 is at its lowest point, the locking member 93 restricts the straightening cylinder 91, the elastic member 92 is in a compressed state, and the trigger rod 94 is away from the locking member 93. The operator places the door frame body 1 on the jig 6, the accommodating block 15 is clamped in the straightening cylinder 91, and the top of the magnet protrudes from the accommodating groove 14. When the second mounting plate 72 begins to descend, the trigger rod 94 triggers the locking member 93 to release the lock on the straightening cylinder 91, and the elastic member 92 lifts the straightening cylinder 91, and the straightening cylinder 91 moves upward. If the magnet is skewed, the top wall of the straightening cylinder 91 abuts against the side wall of the magnet during the upward movement and pushes the magnet to remain in a vertical state. When the straightening cylinder 91 is at its highest point, the elastic member 92 is in a relaxed state, and the second mounting plate 72 just descends until its bottom wall is in contact with the top wall of the straightening cylinder 91, and at this time the trigger rod 94 passes through the workbench 5 through the clearance hole. The second mounting plate 72 continues to descend, and the second mounting plate 72 pushes the magnet and the stabilizing cylinder 91 to descend synchronously. During the descent process, the stabilizing cylinder 91 controls the magnet to maintain a vertical state. The elastic member 92 begins to be compressed.

[0060] When the second mounting plate 72 drops to its lowest point, the magnet installation is completed. At this time, the straightening cylinder 91 is locked by the locking member 93, and the elastic member 92 remains in a compressed state. The second mounting plate 72 starts to rise, and the straightening cylinder 91 is restricted to the lowest point by the locking member 93. The second mounting plate 72 is separated from the straightening cylinder 91 and resets. The trigger rod 94 will not trigger the locking member 93 during the rising process.

[0061] The setting of the straightening cylinder 91 can first push the magnet from bottom to top to restore verticality, and the second mounting plate 72 cooperates with the straightening cylinder 91 to make the magnet drop vertically, reducing the occurrence of magnet breakage caused by skew during installation. The equipment can correct the magnet by itself, which improves the efficiency of magnet installation by eliminating the manual correction process, thereby improving production efficiency; it can also increase the fault tolerance of the equipment for manual pre-installation. The upward movement of the straightening cylinder 91 is driven by the elastic member 92, and the downward movement of the straightening cylinder 91 is driven by the second mounting plate 72 and at the same time stores power for the elastic member 92, without the need to add additional cylinders, reducing the cost of the equipment.

[0062] Reference Figure 7 , in this embodiment, the elastic member 92 is a spring. A guide rod 52 is installed on the workbench 5 by bolts, and the elastic member 92 is sleeved on the guide rod 52 and is located at the bottom end of the guide rod 52. The bottom end of the elastic member 92 is connected to the workbench 5 by welding. An ear plate 911 is integrally formed on the outer peripheral wall of the straightening cylinder 91, and the ear plate 911 is sleeved on the guide rod 52. The top of the elastic member 92 is fixed to the bottom wall of the ear plate 911 by gluing. The elastic member 92 drives the ear plate 911 to move up and down along the guide rod 52, driving the straightening cylinder 91 to reciprocate in the vertical direction.

[0063] The locking member 93 includes a locking rod 931, and a hinge seat is fixedly installed on the workbench 5. The middle part of the locking rod 931 is rotatably connected to the workbench 5 through the hinge seat. A torsion spring 932 is arranged between the locking rod 931 and the hinge seat. One end of the torsion spring 932 is connected to the locking rod 931 by welding, and the other end is connected to the hinge seat by welding. The torsion spring 932 drives the locking rod 931 to rotate downward at the end close to the straightening cylinder 91. An abutment column 933 is integrally formed at one end of the locking rod 931 close to the ear plate 911, and an unlocking column 934 is integrally formed at the other end. The length directions of the abutment column 933 and the unlocking column 934 are both arranged parallel to the horizontal direction. The outer peripheral wall of the abutment column 933 can abut against the top wall of the ear plate 911. A ball head is arranged at one end of the trigger rod 94 away from the second mounting plate 72, and the ball head can abut against the unlocking column 934. The diameter of the ball head is larger than the diameter of the trigger column, and the outer peripheral wall of the unlocking column 934 does not contact the peripheral wall of the trigger rod 94 .

[0064] In the initial state, the straightening cylinder 91 and the ear plate 911 are at their lowest point. At this time, the ear plate 911 is located below the abutment column 933. The torsion spring 932 applies downward pressure to the ear plate 911 through the locking rod 931 and the abutment column 933. The ear plate 911 is difficult to rise, and the elastic member 92 remains in a compressed state. At this time, the ball head of the trigger rod 94 is located above the unlocking column 934. The second mounting plate 72 descends to drive the trigger rod 94 to descend. The ball head of the trigger rod 94 pushes the unlocking column 934 downward, so that the locking rod 931 overcomes the torsion of the torsion spring 932 and rotates in the opposite direction, driving the abutment column 933 to lift up. The elastic member 92 unlocks and drives the ear plate 911 to move up, driving the straightening cylinder 91 to move up. The second mounting plate 72 drives the trigger rod 94 to continue to descend, the trigger rod 94 disengages from the unlocking column 934, and the locking member 93 is reset.

[0065] When the second mounting plate 72 drives the straightening cylinder 91 and the ear plate 911 to descend, until the bottom wall of the ear plate 911 drives the abutting column 933 to rotate downward, and the ear plate 911 is lower than the initial position of the abutting column 933, the abutting column 933 rotates upward to reset and abuts against the top wall of the ear plate 911 again, and the ear plate 911 is difficult to rise. When the second mounting plate 72 rises, the ball head of the trigger rod 94 releases from the unlocking column 934 from below, and only drives the unlocking column 934 to rotate upward. At this time, the abutting column 933 rotates downward, and the ear plate 911 is still blocked by the abutting column 933.

[0066] The setting of the locking member 93 can realize the locking and unlocking of the straightening cylinder 91, and the locking and unlocking processes are linked by the second mounting plate 72, without the need to set up additional power parts such as cylinders, thus saving equipment costs. The action of the locking member 93 is synchronized with the action of the second mounting plate 72, without the need for additional waiting time, thus improving production efficiency.

[0067] The implementation principle of Example 2 is as follows: in the initial state, the ear plate 911 is blocked by the abutment column 933, the elastic member 92 is in a compressed state, the straightening cylinder 91 is at its lowest point, the second mounting plate 72 is at its highest point, and the ball head of the trigger rod 94 is above the unlocking column 934. The operator clamps the door frame body 1 on the fixture 6, and the accommodation block 15 is clamped in the straightening cylinder 91, and the top wall of the straightening cylinder 91 is lower than the top wall of the accommodation block 15. The second mounting plate 72 descends, the ball head of the trigger rod 94 pushes the trigger column to rotate downward, the abutment column 933 rotates upward to release the ear plate 911, the elastic member 92 drives the ear plate 911 and the straightening cylinder 91 to rise, and the straightening cylinder 91 pushes the magnet from bottom to top to restore verticality, and the magnet posture correction is completed. The second mounting plate 72 continues to descend, driving the straightening cylinder 91 and the magnet to descend synchronously, and the magnet remains in a vertical state under the joint action of the straightening cylinder 91 and the second mounting plate 72, thereby improving the installation quality of the magnet. The second mounting plate 72 drives the straightening cylinder 91 and the ear plate 911 to descend to the lowest point, stores energy in the elastic member 92, and the abutment column 933 relocks the ear plate 911. The second mounting plate 72 is reset and separated from the straightening cylinder 91 to wait for the next correction. The automatic posture correction of the magnet is realized, and the installation quality of the magnet is improved; at the same time, the magnet installation efficiency is improved, and the equipment cost is reduced.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
