Description

Technical Field

[0001] This utility model relates to the technical field of junction box processing, and in particular to a rapid processing device for the side of thin metal junction boxes. Background Technology

[0002] Thin metal junction boxes, as key components for cable connection and protection, are widely used in residential, industrial, and smart building applications due to their compact structure, light weight, and excellent protective performance. With the increasing market demand for miniaturized and integrated products, the processing requirements for thin metal junction boxes are becoming increasingly stringent. These boxes require multiple processes such as punching, edge trimming, and tapping, while ensuring that the box body exhibits no significant deformation and meets dimensional accuracy standards after processing. However, traditional processing steps are typically performed at multiple workstations. The transfer and handling of materials between workstations is time-consuming and labor-intensive, requiring at least one worker to operate the equipment at each workstation, resulting in low production efficiency and high labor costs. Furthermore, waste generated during processing can easily accumulate on the processing equipment, potentially damaging the equipment and contaminating the surface of the workpiece, thus affecting product performance. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a rapid processing device for the side of thin metal junction boxes. The processing device includes a junction box placement mechanism and a processing mechanism. The processing mechanism is disposed on one side of the junction box placement mechanism and is configured to move towards the junction box placement mechanism under the drive of a drive mechanism to process the junction box to be processed placed on the junction box placement mechanism. During lateral processing, the processing mechanism can directly align with the side area, avoiding interference with complex side structures caused by traditional "top processing" and reducing hole position errors.

[0004] Furthermore, the junction box placement mechanism includes a first mold base, on which a plurality of placement blocks are provided. Each placement block is provided with an inner mold that matches the shape and size of the junction box to be processed. Quick shape change can be achieved by changing the inner mold of different sizes (to match different junction box specifications). The shape of the inner mold includes the shape of the junction box after processing in the previous process, which can better place the junction box to be processed on the inner mold.

[0005] Furthermore, the inner membrane is provided with a groove or a first through hole of the same size as the junction box to be processed.

[0006] Furthermore, the placement block is provided with a pair of guide holes and a pair of guide grooves, which are symmetrically arranged with respect to the center line of the inner mold.

[0007] Furthermore, the processing mechanism includes a second mold base, a fixed block, a connecting block, a buffer block, and a processing execution component. The fixed block is fixed on the second mold base, the connecting block is disposed on the fixed block, the processing execution component is detachably connected to the connecting block, a spring is provided between the connecting block and the buffer block, the buffer block has a first connecting hole, a second connecting hole, and a third connecting hole arranged sequentially from top to bottom, and the buffer block also has a second through hole that matches the shape of the processing execution component; the bottom of the fixed block, the connecting block, and the buffer block are all provided with slots.

[0008] Furthermore, a first guide post, a second guide post, and a third guide post are sequentially provided on the connecting block corresponding to the first, second, and third connecting holes. The first guide post passes through the first connecting hole, and the second guide post passes through the second connecting hole. A locking head is provided at one end of the second guide post near the buffer block to limit the movement range of the buffer block. The third guide post passes through the third connecting hole and is placed inside the guide hole. The length of the third guide post is greater than that of the second and first guide posts. During processing, because the processing mechanism is close to the placement block, part of the second guide post can be placed in the guide groove.

[0009] Furthermore, the processing mechanism also includes a locking module. The locking module has a first inclined surface, and the fixing block has a second inclined surface that matches the first inclined surface. The locking module is fixed on the second mold base and is located directly above or below the second inclined surface. The inclined surface cooperates to hold the fixing block in place, preventing the fixing block from shifting and ensuring the accuracy requirements of the hole position and edge perpendicularity of the thin junction box. At the same time, the inclined surface of the locking module and the fixing block cooperate to disperse lateral forces, reduce the wear of moving parts (such as guide rails and hydraulic cylinders), and reduce the frequency of equipment maintenance.

[0010] Furthermore, the fixing block is also provided with a guide block, and the guide block is provided with a locking block, which is matched with the locking slot.

[0011] Furthermore, the processing execution components include a cutter, a punching punch, a thread-drawing punch, a bulge-forming punch, and a bending punch.

[0012] Furthermore, when the processing execution component includes a cutter, the corresponding placement block is provided with a waste collection hole larger than the cutter size, which can collect cutting waste in real time and reduce downtime for cleaning due to waste accumulation.

[0013] Furthermore, the buffer block is provided with a stop block, which is configured to fix the junction box to be processed when the processing mechanism is used to process the junction box placed on the junction box placement mechanism.

[0014] This utility model has the following beneficial effects:

[0015] (1) In this utility model, the junction box placement mechanism accurately matches the shape and size of the box to be processed with the inner mold, and the block fixes the box. In the processing mechanism, the symmetrical cooperation of the guide column with the guide hole and guide groove, and the anti-displacement design of the locking module by the inclined surface pressing against the fixing block can effectively solve the problem of positioning reference offset in traditional process.

[0016] (2) The processing execution components in this utility model include multiple tools such as a cutter, a punching punch, and a tooth-pulling punch, which can complete multiple processes in a single or continuous stroke, avoiding the material transfer time of traditional single-process equipment;

[0017] (3) In this utility model, the waste collection hole is set to correspond to the cutting process, which can collect cutting waste in real time and reduce the downtime for cleaning caused by waste accumulation;

[0018] (4) The modular design of the placement block and the inner mold in this utility model can achieve quick change of form by replacing the inner mold of different sizes (matching different junction box specifications). At the same time, the detachable connection between the processing execution component and the connecting block makes it easy to flexibly change tools (such as punching punches of different diameters and bending punches of different angles) according to process requirements, so as to meet the production needs of multiple varieties and small batches.

[0019] (5) This utility model integrates multiple processes into one, reducing the need for manpower and improving processing efficiency. Attached Figure Description

[0030] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. However, this embodiment is not intended to limit this utility model. Any similar structure or similar variation of this utility model should be included in the protection scope of this utility model. The commas in this utility model all indicate the relationship between and. The English letters in this utility model are case-sensitive.

[0031] like Figure 1 As shown, this utility model provides a rapid processing device for the side of a thin metal junction box. The processing device includes a junction box placement mechanism 1 and a processing mechanism 2. The processing mechanism 2 is disposed on one side of the junction box placement mechanism 1. The processing mechanism 2 is configured to move towards the junction box placement mechanism 1 under the drive of a drive mechanism 3 and process the junction box 4 to be processed placed on the junction box placement mechanism 1. During side processing, the processing mechanism 2 can directly align with the side area, avoiding interference with complex side structures caused by traditional "top processing" and reducing hole position errors.

[0032] like Figure 2-3 As shown, the junction box placement mechanism 1 includes a first mold base 11, on which multiple placement blocks 111 are provided. Each placement block 111 has an inner mold 112 that matches the shape and size of the junction box to be processed. Quick shape change is achieved by replacing the inner mold 112 with different sizes (to match different junction box specifications). The shape of the inner mold 112 includes the shape of the junction box after processing in the previous step, allowing for better placement of the junction box to be processed on the inner mold 112. The inner mold 112 has a groove or a first through hole of the same size as the junction box to be processed. Each placement block 111 has a pair of guide holes 1111 and a pair of guide grooves 1112, which are symmetrically arranged relative to the center line of the inner mold 112.

[0033] like Figure 4-5As shown, the processing mechanism 2 includes a second mold base 21, a fixing block 22, a connecting block 23, a buffer block 24, and a processing execution component 25. The fixing block 22 is fixed on the second mold base 21, and the connecting block 23 is disposed on the fixing block 22. The processing execution component 25 is detachably connected to the connecting block 23. A spring is provided between the connecting block and the buffer block. The buffer block 24 is provided with a first connecting hole 241, a second connecting hole 242, and a third connecting hole 243 from top to bottom. The buffer block 24 is also provided with a second through hole 244 that matches the shape of the processing execution component. The bottom of the fixing block 22, the connecting block 23, and the buffer block 24 are all provided with a slot 220. A first guide post 231, a second guide post 232, and a third guide post 233 are sequentially provided on the connecting block corresponding to the first connecting hole 241, the second connecting hole 242, and the third connecting hole 243. The first guide post 231 passes through the first connecting hole 241, and the second guide post 232 passes through the second connecting hole 242. A locking head 234 is provided at one end of the second guide post 232 near the buffer block 24 to limit the movement range of the buffer block 24. The third guide post 233 passes through the third connecting hole 243 and is placed in the guide hole 1111. The length of the third guide post 233 is greater than that of the second guide post 232 and the first guide post 231. During processing, since the processing mechanism 2 is close to the placement block 111, part of the second guide post can be placed in the guide groove 1112. The driving mechanism 3 is fixed on the second mold base 21. The driving mechanism 3 is preferably a hydraulic cylinder, which is configured to provide power to the processing mechanism 2. The buffer block 24 is provided with a stop block 245, which is configured to fix the junction box to be processed when the processing mechanism 2 is set to process the junction box to be processed placed on the junction box placement mechanism 1.

[0034] Preferably, if the processing speeds of adjacent processes are the same, the second mold base 21 can be shared.

[0035] The processing mechanism 2 further includes a locking module 26. The locking module 26 has a first inclined surface, and the fixing block 22 has a second inclined surface that matches the first inclined surface. The locking module 26 is fixed on the second mold base 21 and is positioned directly above or below the second inclined surface. The inclined surface engages with the fixing block 22 to prevent displacement, ensuring the accuracy requirements of the hole positions and edge perpendicularity of the thin junction box. At the same time, the inclined surface of the locking module and the fixing block work together to disperse lateral forces, reducing wear on moving parts (such as guide rails and hydraulic cylinders) and lowering the frequency of equipment maintenance. Preferably, at least one locking module 26 is provided on the same side. One can be provided when fixing the short side of the junction box, and two or more can be provided when fixing the long side of the junction box. The number of modules is determined by the length to be fixed.

[0036] like Figure 5As shown, the fixing block 22 is also provided with a guide block 222, and the guide block 222 is provided with a locking block 223, which is matched with the locking slot 220.

[0037] The processing execution component 25 includes a cutter, a punching punch, a tooth-drawing punch, a convex forming punch, and a bending punch. When the processing execution component 25 includes a cutter 251, the corresponding placement block 111 is provided with a waste collection hole 1110 larger than the cutter size, which can collect cutting waste in real time and reduce downtime for cleaning due to waste accumulation.

[0038] Example

[0039] like Figure 6-8 As shown, the lifting lugs on the short side of the unprocessed junction box need to be trimmed, punched, threaded, and bent; the long side needs to be embossed; and the two circular grooves need to be trimmed, punched, and embossed. Therefore, the rapid processing device of this utility model includes a junction box placement mechanism 1 and a processing mechanism 2. The processing mechanism 2 is located on one side of the junction box placement mechanism 1. The processing mechanism 2 is configured to move towards the junction box placement mechanism 1 under the drive of the drive mechanism 3 and process the junction box 4 to be processed placed on the junction box placement mechanism 1. The system is equipped with eight processing stations as required. The first processing station 51 performs edge trimming, punching, and threading on the short side of the junction box; the second processing station 52 performs edge trimming, punching, and threading on the other short side of the junction box; the third processing station 53 trims the long side of the junction box; the fourth processing station 54 punches and embosses the long side of the junction box; the fifth processing station 55 trims the other long side of the junction box; the sixth processing station 56 punches and embosses the other long side of the junction box; the seventh processing station 57 bends the short side of the junction box; and the eighth processing station 58 bends the other short side of the junction box.

[0040] Each processing station's processing mechanism includes a second mold base 21, a fixing block 22, a connecting block 23, a buffer block 24, a processing execution component 25, and a locking module 26. The fixing block 22 is fixed to the second mold base 21, and the connecting block 23 is disposed on the fixing block 22. The processing execution component 25 is detachably connected to the connecting block 23. A spring is provided between the connecting block 23 and the buffer block 24. When the buffer block 24 contacts the junction box placement mechanism 1, under the continued drive of the drive mechanism 3, the processing execution component disposed on the connecting block 23 is compressed by the spring. The component passes through the second through hole 244 to process the junction box. The locking module 26 has a first inclined surface, and the fixing block 22 has a second inclined surface that matches the first inclined surface. The locking module 26 is fixed on the second mold base 21 and is located directly above or below the second inclined surface. The inclined surface cooperates to hold the fixing block 22 in place, preventing the fixing block 22 from shifting and ensuring the accuracy requirements of the hole position and edge perpendicularity of the thin junction box. At the same time, the inclined surface of the locking module and the fixing block cooperate to disperse lateral forces, reduce the wear of moving parts (such as guide rails and hydraulic cylinders), and reduce the frequency of equipment maintenance. Preferably, there is at least one locking module 26 on the same side. One can be set when fixing the short side of the junction box, and two or more can be set when fixing the long side of the junction box. The number of locking modules depends on the length to be fixed.

[0041] The buffer block 24 is provided with a first connecting hole 241, a second connecting hole 242, and a third connecting hole 243 from top to bottom. The buffer block 24 also has a second through hole 244 that matches the shape of the processing execution component. The bottom of the fixing block 22, connecting block 23, and buffer block 24 are all provided with slots 220. The connecting blocks corresponding to the first connecting hole 241, second connecting hole 242, and third connecting hole 243 are provided with a first guide post 231, a second guide post 232, and a third guide post 233 in sequence. The first guide post 231 passes through the first connecting hole 241, and the second guide post 232 passes through the second connecting hole 242. A lock head 234 is provided at one end of the second guide post 232 near the buffer block 24 to limit the movement range of the buffer block 24. Wherein, as Figure 10As shown, the processing execution components of the first processing station 51 include a cutter 251, a punching punch 253, and a thread-drawing punch 252; the processing execution components of the second processing station 52 include a cutter 251, a punching punch 253, and a thread-drawing punch 252; the processing execution components of the third processing station 53 include a cutter, the length of which should match the length of the long side of the junction box; the processing execution components of the fourth processing station 54 include a punching punch and a convex forming punch; the processing execution components of the fifth processing station 55 include a cutter; the processing execution components of the sixth processing station 56 include a punching punch and a convex forming punch; the processing execution components of the seventh processing station 57 include a bending punch; and the processing execution components of the eighth processing station 58 include a bending punch. Since the processing speeds of the first and second processing stations, the third and fourth processing stations, the fifth and sixth processing stations, and the seventh and eighth processing stations are the same, the first and second processing stations share a second mold base, the third and fourth processing stations share a second mold base, the fifth and sixth processing stations share a second mold base, and the seventh and eighth processing stations share a second mold base.

[0042] The drive mechanism 3 is fixed on the second mold base 21. The drive mechanism 3 is preferably a hydraulic cylinder, which is configured to provide power to the processing mechanism 2. The buffer block 24 is provided with a stop block 245, which is configured to fix the junction box to be processed when the processing mechanism 2 is set to process the junction box to be processed placed on the junction box placement mechanism 1.

[0043] The fixing block 22 is also provided with a guide block 221, and the guide block 221 is provided with a locking block 222, which is matched with the locking slot 220.

[0044] The junction box placement mechanism 1 includes a first mold base 11. Since the processing speed of the fourth processing station is greater than that of the fifth processing station, a placement position is set at a corresponding position between the fourth and fifth processing stations to balance the speeds. Therefore, the first mold base 11 has nine placement blocks 111, i.e., nine placement stations. The inner mold shape of the first placement station 61 is the shape of an unprocessed junction box with its short side facing the processing mechanism 2. The inner mold shape of the second placement station 62 is the shape of a junction box with its short side facing the processing mechanism 2 and includes the shape of a junction box processed by the first placement station. The inner mold shape of the third placement station 63 is the shape of a junction box with its long side facing the processing mechanism 2 and includes the shape of a junction box processed by the second placement station. The fourth placement station 64... The inner membrane shape of the first, second, third, and fifth placement stations is such that its long side faces the processing mechanism 2 and includes the junction box shape processed at the third placement station. The inner membrane shape of the fifth placement station 65 is the same as that of the fourth placement station. The inner membrane shape of the sixth placement station 66 is such that its long side faces the processing mechanism 2 and includes the junction box shape processed at the fourth placement station. The inner membrane shape of the seventh placement station 67 is such that its long side faces the processing mechanism 2 and includes the junction box shape processed at the sixth placement station 66. The inner membrane shape of the eighth placement station 68 is such that its short side faces the processing mechanism 2 and includes the junction box shape processed at the seventh placement station. The inner membrane shape of the ninth placement station 69 is such that its short side faces the processing mechanism 2 and includes the junction box shape processed at the eighth placement station. The placement blocks 111 at the first, second, third, and fifth placement stations are equipped with waste collection holes 1110 larger than the cutter size, which can collect cutting waste in real time, reducing downtime for cleaning due to waste accumulation.

[0045] The placement block 111 is provided with a pair of guide holes 1111 and a pair of guide grooves 1112. The guide holes 1111 and guide grooves 1112 are symmetrically arranged with respect to the center line of the inner mold 112. The third guide post 233 passes through the third connecting hole 243 and is placed in the guide hole 1111. During processing, since the processing mechanism 2 is close to the placement block 111, part of the second guide post can be placed in the guide groove 1112.

[0046] During processing, the junction box to be processed is placed on the first placement station by the robot arm. Under the action of the drive mechanism 3, the processing execution component is moved to the junction box placement mechanism for processing under the guidance of the first guide post 231, the second guide post 232, the third guide post 233 and the guide block. After the processing of the first processing station is completed, the junction box is clamped, translated and / or turned by the robot arm. At the same time, the processing of eight processing stations is performed.

[0047] The junction box placement mechanism in this invention precisely matches the shape and size of the box to be processed with the inner mold, and the stop block fixes the box. In the processing mechanism, the symmetrical cooperation of the guide post, guide hole, and guide groove, as well as the anti-displacement design of the locking module by the inclined surface pressing against the fixing block, can effectively solve the problem of positioning reference offset in traditional processes. The modular design of the placement block and the inner mold can achieve quick changeover by replacing the inner mold of different sizes (to match different junction box specifications). At the same time, the detachable connection between the processing execution component and the connecting block makes it easy to flexibly change tools (such as punches with different hole diameters and bending dies with different angles) according to process requirements, so as to meet the production needs of multiple varieties and small batches.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.
