Description

Technical Field

[0001] This invention relates to the field of air conditioning processing equipment technology, and in particular to a dismantling device. Background Technology

[0002] Air conditioners are indispensable in modern life. Their key components, the condenser and evaporator, are made of several long U-shaped copper tubes connected and welded together by small elbows. These small elbow copper tubes serve as the connecting pipes between the two units, forming the refrigeration loop and cooling system when combined with the internally threaded U-shaped copper tubes. Currently, after the small elbows are fitted with welding rings, they are automatically flame-brazed into components. However, during the process of fitting the welding rings onto the elbows and during subsequent transportation, a series of problems arise, such as flattening, scratches, and deformation of the pipe ends. These elbows become unusable and require complete removal of the welding rings for recycling and reuse.

[0003] However, at present, the removal of weld rings mainly relies on manual hammering, which cannot effectively guarantee the integrity of the weld rings. If the weld rings are damaged during the removal process, they cannot be used. Materials with severe deformation of elbow pipe openings cannot be effectively disassembled. Due to the small size of the elbows, improper operation with pliers may cause injury to employees. Moreover, the disassembly is slow. According to statistics, an employee can disassemble 20 elbow weld rings in 1 hour. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this invention is to provide a dismantling device that can quickly and effectively remove the weld ring at the elbow and ensure the integrity of the weld ring during recycling.

[0005] The technical solution adopted by this invention to solve its technical problem is: a demolition device, comprising:

[0006] The separation mechanism includes a movable clamping block and a first driving member. The first driving member is connected to the movable clamping block. The movable clamping block is disposed opposite to the elbow pipe opening. The first driving member drives the movable clamping block to perform an opening and retracting action to reduce the elbow pipe opening.

[0007] The moving mechanism includes a fixed base, a top block disposed on the fixed base, and a second driving member. The second driving member is connected to the top block. The top block limits and fixes the elbow. The welding ring extends out from the front side of the fixed base. The second driving member drives the top block to move the elbow away from the welding ring.

[0008] As a further improvement of the present invention: the fixing base is provided with a slot, one end of the slot extends to the front side of the fixing base, and the slot is provided with an arc-shaped recess.

[0009] As a further improvement of the present invention: the movable clamping block is provided with a first clamping block and a second clamping block, the first clamping block and the second clamping block are arranged opposite to each other, the inner side of the front section of the first clamping block is provided with a first recess, the inner side of the front section of the second clamping block is provided with a second recess, and the first recess and the second recess form a compression space.

[0010] As a further improvement of the present invention: a fixing sleeve is provided on the outer periphery of the first clamping block and the second clamping block, and the fixing sleeve is fixedly connected to the first driving member.

[0011] As a further improvement of the present invention: the cross-section of the extrusion space is circular, and the extrusion space gradually increases in size along the direction close to the welding ring.

[0012] As a further improvement of the present invention: a positioning protrusion is provided on the inner side of the fixing sleeve, and the outer sides of the first clamping block and the second clamping block respectively abut against the positioning protrusion. The end of the positioning protrusion that abuts against the first clamping block and the second clamping block is provided with a convex arc portion.

[0013] As a further improvement of the present invention: the front end of the fixed base is provided with a first limiting clamp and a second limiting clamp, the first limiting clamp and the second limiting clamp are arranged opposite to each other, the first limiting clamp is connected to a first driving source, and the second limiting clamp is connected to a second driving source.

[0014] As a further improvement of the present invention: sensors are respectively provided on the inner sides of the first limiting clamp and the second limiting clamp, and the sensors are connected to the control system.

[0015] As a further improvement of the present invention, it also includes a base and a vision camera. The base is provided with a receiving area below it, which connects the gap between the base and the fixed base. The receiving area is provided with a first feeding mechanism and a second feeding mechanism. The first feeding mechanism pushes the unqualified welding ring to the buffer area, and the second feeding mechanism pushes the qualified welding ring to the qualified material tank.

[0016] As a further improvement of the present invention, it also includes a conveying mechanism, which is provided with a first conveyor belt and a second conveyor belt. The first conveyor belt is connected to the second transmission belt. The second conveyor belt is inclined along the length direction of the slot, and the unloading end of the second conveyor belt is located near the top block.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention designs a separation mechanism in which a movable clamping block is positioned opposite the elbow opening. A first driving component drives the movable clamping block to cyclically open and close, reducing the elbow opening. A top block on a fixed base limits and fixes the elbow, causing the welding ring to abut against the front side wall of the fixed base. A second driving component drives the top block to move the elbow away from the welding ring. Because the separation mechanism reduces the diameter of the elbow opening, the integrity of the welding ring is maintained when the elbow moves relative to it, facilitating the recycling and reuse of the welding ring. This achieves efficient separation of the elbow and welding ring, reducing the labor intensity of operators. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] In order to solve the technical problems in the prior art, the present invention will now be further described in conjunction with the accompanying drawings and embodiments:

[0030] like Figures 1 to 5 As shown, this embodiment of the invention discloses a dismantling device, including a moving mechanism 2 and a separating mechanism 1. The separating mechanism 1 includes a movable clamping block 12 and a first driving member 13. The first driving member 13 is connected to the movable clamping block 12. The movable clamping block 12 is disposed opposite to the elbow pipe opening. The first driving member 13 drives the movable clamping block 12 to perform cyclic opening and closing actions to reduce the elbow pipe opening. The moving mechanism 2 includes a fixed base 23 and a top block 21 and a second driving member 22 disposed on the fixed base 23. The second driving member 22 is connected to the top block 21. The top block 21 limits and fixes the elbow. The welding ring extends out of the front side of the fixed base 23. The second driving member 22 drives the top block 21 to move the elbow away from the welding ring.

[0031] In this embodiment, the elbow welding ring is placed on the fixed base 23, so that the welding ring on the elbow extends out of the front side of the fixed base 23 or abuts against the front side wall of the fixed base 23. Specifically, the lower side of the welding ring abuts against the front side wall of the fixed base 23. The elbow is limited and fixed by the top block 21. The movable clamping block 12 of the separation mechanism 1 is set opposite to the elbow pipe opening. The welding ring is sleeved on the elbow pipe opening end. The first driving member 13 drives the movable clamping block 12, which is in the open state, to clamp the elbow pipe opening and perform a contraction action. The opening and contraction actions can be repeated multiple times, so that the elbow pipe opening shrinks, that is, the pipe opening diameter at the elbow welding ring end is squeezed and reduced. At this time, the diameter of the welding ring is larger than that of the elbow pipe opening. By controlling the first driving component 13, the movable clamping block 12 changes from a retracted state to an open state, releasing the elbow pipe opening. Then, the second driving component 22 of the moving mechanism 2 drives the top block 21 to move, thereby driving the elbow to move away from the welding ring. In addition, the welding ring is abutted by the front side wall of the fixed seat 23, which smoothly separates the welding ring from the elbow. At the same time, it effectively ensures the integrity of the welding ring itself and facilitates the recycling of the welding ring. Compared with the current method of manually knocking off the welding ring, the removal device of this embodiment improves the separation efficiency of the welding ring and the elbow and is less likely to damage the welding ring.

[0032] For severely deformed elbow pipe openings, this removal device is used. First, the first driving component 13 and the movable clamping block 12 of the separation mechanism 1 are used to shrink the deformed elbow pipe opening. The movable clamping block 12 is driven to open and close so that the maximum diameter of the elbow pipe opening is smaller than the diameter of the welding ring. In this way, as the second driving component 22 drives the top block 21 to push the elbow away from the direction of the welding ring, the welding ring is successfully detached from the elbow pipe opening and falls from the front side of the fixed seat 23, avoiding the safety hazards of manually removing the welding ring of a severely deformed elbow.

[0033] In this embodiment, the elbow welding ring is limited and fixed by the top block 21. When separated, the welding ring abuts against the front side wall of the fixed seat 23. This can limit the position of the elbow welding ring on the fixed seat 23, and also prevent the elbow welding ring from moving when the first driving member 13 and the movable clamping block 12 retract the elbow pipe opening. This is beneficial for the movable clamping block 12 to position the elbow pipe opening and clamp the elbow pipe opening.

[0034] In some embodiments, the top block 21 is embedded between two straight pipe sections of the elbow. When the second drive member 22 drives the top block 21 to move, the top block 21 pushes the elbow as a whole to move. During the movement, the elbow does not deviate much to the left or right and does not shake.

[0035] Furthermore, the top block 21 has an arc-shaped portion 211 at one end near the curved section of the bend, the curvature of which is adapted to the curved section. Designing one end of the top block 21 with an arc-shaped portion 211 helps to ensure the stability of the bend during its movement.

[0036] Furthermore, the top block 21 and the welding ring abut against the front side wall of the fixed seat 23, effectively fixing the elbow welding ring on the fixed seat 23. During the process of the first driving member 13 driving the movable clamping block 12 to retract the elbow pipe opening, the top block 21 can prevent the elbow from moving towards the movable clamping block 12, and the abutment between the welding ring and the front side wall of the fixed seat 23 can prevent the elbow from moving away from the movable clamping block 12. Thus, the reliability and accuracy of the first driving member 13 and the movable clamping block 12 performing the retraction action on the elbow pipe opening are improved.

[0037] like Figure 1 and Figure 2As shown, this embodiment also includes a base 11, which is spaced apart from a fixed base 23. A gap is left between the front side of the fixed base 23 and the base 11, and a platform is provided below the front side of the fixed base 23. The first driving member 13 of the separation mechanism 1 is mounted on the base 11. The movable clamping block 12 is positioned close to the welding ring and opposite to the elbow opening. After the first driving member 13 drives the movable clamping block 12 to retract the elbow opening, the second driving member 22 drives the top block 21 to push the elbow away from the welding ring. The welding ring smoothly falls from the gap onto the platform below, and the welding ring and the elbow are separated. Furthermore, the gap between the front side of the fixed base 23 and the base 11 is adjusted according to the distance between the welding ring and the elbow opening, as long as it is ensured that the movable clamping block 12 does not press together with the welding ring when retracting the elbow opening.

[0038] like Figure 1 and Figure 2 As shown, a material discharge groove 3 is provided on the rear side of the fixed base 23. The second driving component 22 drives the elbow to move away from the welding ring through the top block 21. The elbow falls from the rear side of the fixed base 23 into the material discharge groove 3. After the elbow is removed from the welding ring, the elbow is recovered through the material discharge groove 3.

[0039] Furthermore, the second driving component 22 employs a rodless cylinder. The piston end of the rodless cylinder is fixedly connected to the top block 21. The top block 21 reciprocates with the piston. After the first separated elbow falls into the discharge trough 3 under the action of the top block 21 and the piston, the piston drives the top block 21 to move towards the front of the fixed seat 23. After the next elbow weld ring passes through the separation mechanism 1, the piston of the rodless cylinder again drives the elbow with the narrowed pipe opening to move towards the rear of the fixed seat 23 via the top block 21, and so on in a reciprocating cycle. In this embodiment, a rodless cylinder that rotates discreetly on the fixed seat 23 is used to complete the separation of the elbow and the weld ring, saving installation space. Magnetic couple rodless cylinders and mechanical rodless cylinders can be used.

[0040] like Figure 4 As shown, in some embodiments, a slot 231 is provided on the fixing base 23, with one end of the slot 231 extending to the front side of the fixing base 23. For the shape of the elbow, preferably, slots 231 are designed on the left and right sides of the fixing base 23 to respectively limit and fix the two straight pipe sections of the elbow. The spacing between the slots 231, the width of the slots 231, and the length are adjusted according to the specific model and size of the elbow.

[0041] On the one hand, the slot 231 facilitates the positioning of the elbow welding ring on the fixed seat 23, and the slot 231 can play a certain role in fixing the elbow welding ring. The pipe section at the end of the elbow welding ring is limited in the slot 231, and the welding ring on the elbow abuts against the front side wall of the fixed seat 23. On the other hand, with the elbow welding ring positioned in the slot 231, when the first driving member 13 and the movable clamping block 12 perform the retraction action on the elbow pipe opening, the elbow is not easy to shift in position, and the relative position between the elbow pipe opening and the movable clamping block 12 is not easy to shift, which makes it easy for the movable clamping block 12 to smoothly clamp and retract the elbow pipe opening.

[0042] Furthermore, the slot 231 is provided with an arc-shaped recess, which fits against the outer wall of the elbow pipe, so that the elbow is more stably limited in the slot 231. The slot 231 and the arc-shaped recess form a fitting slot 231, which is adapted to the shape of the elbow. The cross-section of the fitting slot 231 can be semi-circular.

[0043] Of course, the elbow can be limited and fixed even without the arc-shaped recess in the slot 231. For example, the cross-section of the slot 231 is an open rectangular shape. Embedding a part of the elbow pipe into the slot 231 can also serve the purpose of limiting and fixing it.

[0044] like Figure 1 , 2 As shown in Figure 3, in some embodiments, the movable clamping block 12 is provided with a first clamping block 121 and a second clamping block 122. The first clamping block 121 and the second clamping block 122 are arranged opposite to each other. The rear end of the first clamping block 121 is connected to the rear end of the second clamping block 122. The first clamping block 121 and the second clamping block 122 can move towards each other or move away from each other. Specifically, the front part of the first clamping block 121 and the front part of the second clamping block 122 can approach each other, retract, separate from each other, and open.

[0045] When the first driving member 13 drives the movable clamping block 12 to perform a retraction action on the elbow pipe opening, when the front section of the first clamping block 121 and the front section of the second clamping block 122 approach each other, the elbow pipe opening is clamped between the front section of the first clamping block 121 and the front section of the second clamping block 122. The first driving member 13 drives the first clamping block 121 and the second clamping block 122 to open and retract multiple times, repeatedly shaping and reducing the diameter of the elbow pipe opening.

[0046] After the diameter of the elbow pipe opening is reduced, the first driving member 13 drives the movable clamping block 12 to perform an opening action on the elbow pipe opening. The elbow pipe opening is still located between the front section of the first clamping block 121 and the front section of the second clamping block 122, but the elbow pipe opening does not contact the front section of the first clamping block 121 or the front section of the second clamping block 122. The elbow pipe opening is separated from the movable clamping block 12.

[0047] Specifically, in this embodiment, the movable clamping block 12 can be made to retract and open the first clamping block 121 and the second clamping block 122 using principles similar to tweezers, clamps, pliers, and scissors.

[0048] Preferably, the rear end of the first clamping block 121 and the rear end of the second clamping block 122 can be directly connected, or the rear end of the first clamping block 121 and the rear end of the second clamping block 122 can be connected by a hinge. When the movable clamping block 12 is in the open state, there is an angle between the front end of the first clamping block 121 and the front end of the second clamping block 122.

[0049] Regardless of the connection method between the rear end of the first clamping block 121 and the rear end of the second clamping block 122, it is only necessary to ensure that the first clamping block 121 can move closer to or away from the second clamping block 122 with the connection point between the first clamping block 121 and the second clamping block 122 as the fulcrum of rotation, and the second clamping block 122 can move closer to or away from the first clamping block 121 with the connection point between the first clamping block 121 and the second clamping block 122 as the fulcrum of rotation.

[0050] In some embodiments, a fixed sleeve 14 is fitted around the outer periphery of the movable clamping block 12. Furthermore, the fixed sleeve 14 is movably fitted around the outer periphery of the first clamping block 121 and the second clamping block 122. The fixed sleeve 14 is connected to the first driving member 13, which provides driving force to drive the fixed sleeve 14 to slide along the direction close to the welding ring on the first clamping block 121 and the second clamping block 122, so that the first clamping block 121 and the second clamping block 122 move closer to each other and contract, clamping and compressing the elbow pipe opening.

[0051] In a specific example, the output end of the first driving component 13 is connected to a push rod, which is connected to the fixed sleeve 14. The first driving component 13 adopts a telescopic motor or a telescopic cylinder. When the first driving component 13 drives the push rod to move closer to the welding ring, the push rod drives the fixed sleeve 14 to move closer to the welding ring. The fixed sleeve 14 gradually presses and contracts the first clamping block 121 and the second clamping block 122. At this time, the first clamping block 121 and the second clamping block 122 cover the elbow pipe opening. During the contraction process, the diameter of the elbow pipe opening is reduced.

[0052] The fixing sleeve 14 is a frame structure set on the outer periphery of the first clamping block 121 and the second clamping block 122. When the fixing sleeve 14 moves forward, it squeezes the first clamping block 121 and the second clamping block 122, causing them to come closer together. When the fixing sleeve 14 moves backward, it causes the first clamping block 121 and the second clamping block 122 to separate from each other. The lateral width of the fixing sleeve 14 can be less than or equal to the overall lateral width when the first clamping block 121 and the second clamping block 122 are in full contact. The lateral width of the fixing sleeve 14 can also be less than or equal to the overall lateral width when the first clamping block 121 and the second clamping block 122 are contracted at a certain angle. This certain angle ensures that the diameter of the elbow pipe opening is smaller than the inner diameter of the welding ring. The lateral width of the fixing sleeve 14 can be adjusted according to the actual situation, while the longitudinal height of the fixing sleeve 14 only needs to be no less than the overall lateral width when the first clamping block 121 and the second clamping block 122 are in full contact.

[0053] Generally, there are two movable clamping blocks 12, and correspondingly, there are also two fixed sleeves 14, two first driving components 13, and two push rods.

[0054] To improve the stability of the fixed sleeve 14 sliding on the first clamping block 121 and the second clamping block 122, a Y-shaped or U-shaped bracket is provided. One end of the bracket opening is connected to the left and right sides of the fixed sleeve 14, and the other end of the bracket is fixedly connected to the push rod. Preferably, the push rod and the bracket are designed as an integrally formed structure.

[0055] To improve the smoothness of the sliding of the fixing bracket on the first clamping block 121 and the second clamping block 122, the fixing sleeve 14 is provided with a positioning protrusion 141 on the inner side near the first clamping block 121 and the second clamping block 122. The outer sides of the first clamping block 121 and the second clamping block 122 respectively abut against the positioning protrusion 141. Furthermore, the end of the positioning protrusion 141 that abuts against the first clamping block 121 and the second clamping block 122 is provided with a convex arc portion. The convex arc portion is smooth, so that the positioning protrusion 141 can slide smoothly and easily on the outer sides of the first clamping block 121 and the second clamping block 122.

[0056] Generally, multiple positioning protrusions 141 are designed, which can be designed in one or more rows. More preferably, one end of the positioning protrusion 141 is designed as a hemispherical shape.

[0057] In some embodiments, the inner side of the front section of the first clamping block 121 is provided with a first recess 1211, and the inner side of the front section of the second clamping block 122 is provided with a second recess 1221. The first clamping block 121 and the second clamping block 122 are arranged opposite to each other, and the first recess 1211 and the second recess 1221 are arranged opposite to each other. Regardless of whether the movable clamping block 12 is in the open state or the retracted state, the first recess 1211 and the oppositely arranged second recess 1221 form a compression space, and the maximum diameter of the compression space is smaller than the diameter of the welding ring.

[0058] When the movable clamping block 12 clamps and contracts the elbow pipe opening, the elbow pipe opening comes into close contact with the compression space. At the same time, the first clamping block 121 and the second clamping block 122 approach each other, and the first recess 1211 and the second recess 1221 also approach each other. The compression space gradually shrinks, thus reducing the diameter of the elbow pipe opening. The compression space only needs to reduce the diameter of the elbow pipe opening or the overall diameter to be smaller than the inner diameter of the welding ring. It is not necessary to consider whether the first clamping block 121 and the second clamping block 122 of the movable clamping block 12 are completely fitted together.

[0059] In a specific example, the cross-section of the extrusion space formed by the first recess 1211 and the second recess 1221 is circular, and the cross-section gradually increases along the direction close to the welding ring. Preferably, the extrusion space is conical. More preferably, when the first clamping block 121 and the second clamping block 122 are in contact, the maximum diameter of the extrusion space is smaller than the diameter of the welding ring.

[0060] The cross-section of the compression space formed by the first recess 1211 and the second recess 1221 is designed to be circular. The inner sides of the first clamping block 121 and the second clamping block 122 clamp the constricted elbow pipe opening, so that the cross-section of the elbow pipe opening is reshaped into a circle. Especially for severely deformed elbows, after being shaped by the first clamping block 121 and the second clamping block 122, the overall diameter is reduced and the cross-section is circular. This makes it easier for the second driving member 22 to drive the top block 21 to push the elbow away from the direction of the welding ring, so that the welding ring falls off from the elbow pipe opening.

[0061] In another specific example, the cross-section of the extrusion space can be rhomboid or square, shaping the elbow pipe opening into a square or rhomboid shape. The extrusion space can also be other shapes, and the extrusion space only needs to reduce the diameter of the elbow pipe opening to be smaller than the diameter of the welding ring.

[0062] In some embodiments, the front end of the fixing base 23 is provided with a first limiting clamp 4 and a second limiting clamp 5. The first limiting clamp 4 and the second limiting clamp 5 are arranged opposite to each other. The first limiting clamp 4 and the second limiting clamp 5 move towards the bend to fix the bend. At this time, the first limiting clamp 4 abuts against the straight pipe section on one side of the bend, and the second limiting clamp 5 abuts against the straight pipe section on the other side of the bend. The first limiting clamp 4 and the second limiting clamp 5 move away from the fixed pipe to release the bend.

[0063] When the first drive member 13 of the separation mechanism 1 controls the movable clamping block 12 to perform a shrinking action on the elbow pipe opening, the elbow is tightly fixed on the front end of the fixed seat 23 by the first limiting clamping block 4 and the second limiting clamping block 5. After the diameter of the elbow pipe opening is reduced, the first limiting block and the second limiting block are released, so that the second drive member 22 drives the top block 21 to push the elbow towards the feed trough 3.

[0064] In a specific example, the first limiting clamp 4 is connected to the first driving source, and the second limiting clamp 5 is connected to the second driving source. The first and second driving sources provide driving force to drive the first limiting clamp 4 and the second limiting clamp 5 to move closer to or further away from each other, thereby completing the clamping and loosening of the elbow. This method can be adapted to elbows of different specifications.

[0065] The first limiting clamp 4 and the second limiting clamp 5 work together with the slot 231 structure. The straight pipe section of the elbow is embedded in the slot 231. The slot 231 is adapted to straight pipe sections of elbows of different specifications, and its width is generally designed to be slightly larger. At the same time, the first limiting clamp 4 and the second limiting clamp 5 are telescopically moved to clamp the elbow in the slot 231, further improving the fixed stability of the elbow in the slot 231.

[0066] In some embodiments, sensors are provided on the inner sides of the first limiting clamp 4 and the second limiting clamp 5. The sensors detect whether the elbow opening is between the first limiting clamp 4 and the second limiting clamp 5, so as to control the action of the first driving member 13 and smoothly complete the shrinkage and shaping of the elbow opening.

[0067] Typically, a metal sensor can be designed and connected to the control system 10. When the metal sensor detects the elbow opening, it sends a signal to the control system 10. The control system 10 determines that the elbow is in place, detects the extension and retraction of the first limiting clamp 4 and the second limiting clamp 5, determines the elbow size, and controls the first driving member 13 to open the movable clamp 12 to complete the size matching. Furthermore, the control system 10 controls the first driving member 13 to drive the fixed sleeve 14 to reciprocate on the movable clamp 12, so that the first clamp 121 and the second clamp 122 open and close. The compression space formed by the inner side of the first clamp 121 and the second clamp 122 shapes and shrinks the elbow opening, making it easier to remove the welding ring.

[0068] In some embodiments, a receiving area 6 is provided below the base 11. The receiving area 6 connects the gap between the base 11 and the fixed seat 23. After the welding ring separates from the elbow, it falls from the front side of the fixed seat 23 and can enter the receiving area 6 for temporary storage.

[0069] like Figure 4 and Figure 5 As shown, a vision camera 8, a first unloading mechanism 15, and a second unloading mechanism 16 are further provided. The vision camera 8 is connected to the control system 10. The vision camera 8 captures images of the welding ring falling from the fixed seat 23 onto the receiving area 6 and transmits the images to the control system 10. The control system 10 determines whether the welding ring is qualified. When the determination result is unqualified, the control system 15 moves the welding ring to the buffer area 61 behind the receiving area 6. When the determination result is qualified, the control system 16 moves the welding ring to the qualified material trough 7.

[0070] Preferably, the vision camera 8 is mounted on the front side of the mounting base 23, or on the side of the base 11 near the mounting base 23. Automated picking via visual inspection enables the recycling and reuse of qualified weld rings.

[0071] like Figure 5 As shown, preferably, the first feeding mechanism 15 typically includes a third drive source 151 and a first push plate 152. The first feeding mechanism 15 is disposed on the receiving area 6. The third drive source 151 drives the first push plate 152 to perform linear reciprocating motion. Initially, the first push plate 152 is located on the side of the fixed seat 23. When the weld ring is determined to be unqualified, the third drive source 151 retracts, causing the first push plate 152 to move away from the fixed seat 23, pushing the weld ring to the buffer area 61. Typically, two first feeding mechanisms 15 are disposed on the receiving area 6, respectively for the weld rings on the two straight pipe sections of the elbow. More preferably, the third drive source 151 is a leverless cylinder.

[0072] More preferably, the second feeding mechanism 16 typically includes a fourth drive source 161 and a second push plate 162. The fourth drive source 161 is fixedly connected to the second push plate 162. The fourth drive source 161 drives the second push plate 162 to perform linear reciprocating motion, positioning the qualified material trough 7 opposite to the push plate. Typically, the movement directions of the second push plate 162 and the first push plate 152 are perpendicular to each other.

[0073] More preferably, the fourth drive source 161 can be a telescopic motor or a telescopic cylinder.

[0074] In the initial state, the second pusher plate 162 is located on one side of the receiving area 6. When one of the weld rings is detected to be defective, the control system 10 first controls the third drive source 151 to drive the first pusher plate 152 to move the defective weld ring to the buffer area 61 on the back side of the receiving area 6. Then, the control system 10 controls the fourth drive source 161 to drive the second pusher plate 162 to push the weld ring to the qualified material trough 7 set on the other side of the receiving area 6. The first pusher plate 152 and the second pusher plate 162 do not interfere with each other.

[0075] When both weld rings are determined to be qualified, it is only necessary to control the fourth drive source 161 to drive the second push plate 162 to move the weld rings to the qualified material tank 7. When both weld rings are determined to be unqualified, it is only necessary to control the third drive source 151 to drive the first push plate 152 to push the two weld rings to the buffer area 61.

[0076] like Figure 4As shown, in some embodiments, a conveying mechanism 9 is also included. The conveying mechanism 9 is provided with a first conveyor belt 91 and a second conveyor belt 92. Both the first conveyor belt 91 and the second conveyor belt 92 are higher than the fixed seat 23. The first conveyor belt 91 is connected to the second transmission belt. The second conveyor belt 92 is inclined towards the length direction of the slot 231, and the unloading end of the second conveyor belt 92 is close to the top block 21. When the elbow is conveyed from the first conveyor belt 91 and the second conveyor belt 92 to the top of the fixed seat 23, it slides down at a certain speed at the unloading end of the second conveyor belt 92. Under the action of inertia, the straight pipe section of the elbow opening is smoothly embedded into the slot 231, and the welding ring extends out of the front side of the fixed seat 23. At the same time, under the limiting action of the top block 21, it will not slide out too much displacement from the front side of the fixed seat 23 and fall off, thus completing the unloading of the elbow welding ring very well.

[0077] In summary, after reading this invention document, those skilled in the art can make various other corresponding modifications to the technical solutions and concepts based on this invention without creative mental effort, and all of these modifications fall within the scope of protection of this invention.
