Technical Field
[0001] This utility model relates to the technical field of junction box processing, and in particular to an automatic processing mold and automatic processing device for 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. As the market demands increasingly smaller and more integrated products, the processing requirements for thin metal junction boxes are becoming increasingly stringent. These boxes require multiple processes, including bending, edge cutting, corner cutting, and tapping, while ensuring no significant deformation and dimensional accuracy 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 per workstation, resulting in low production efficiency and high labor costs. Furthermore, waste generated during processing is difficult to separate from the junction box. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides an automatic processing mold for junction boxes, comprising an upper mold structure and a lower mold structure. The lower mold structure includes a placement plate with multiple base plates arranged circumferentially on the placement plate. Each base plate has a placement block, and each placement block has an outer mold on its top that perfectly matches the shape and size of the junction box to be processed. The outer wall of the outer mold corresponds to the processing structure of the processing station of the junction box. The upper mold structure, which is matched with the lower mold structure, moves vertically downward under the action of a driving device, achieving precise matching with the lower mold structure and pushing the processing structure to perform processing actions.
[0004] Furthermore, the lower mold structure also includes a lower mold base, a lower pad, and a fixing plate. The lower pad is fixed on the lower mold base, and the fixing plates are evenly distributed between the lower pad and the placement plate. The placement plate is provided with a positioning block and a guide sleeve. The placement plate is also provided with a first support column, which is used to support the upper mold structure.
[0005] Furthermore, the processing structure includes a stop block, a slider, a stop block, and a processing execution component. The processing execution component is disposed on the slider, which is disposed on the outer side wall of the corresponding outer mold to be processed. The slider is slidably connected to the base plate. The stop block is fixed on the placement plate to limit the position of the slider. The slider is disposed between the stop block and the outer mold. The stop block is fixed on the base plate and located on both sides of the slider.
[0006] Furthermore, the processing execution components include a long-side cutter, a short-side cutter, a corner cutter, a knock-out punch, and a bending punch.
[0007] Furthermore, the slider is provided with a processing execution component placement position, a first inclined surface and a first limiting surface. The processing execution component placement position and the first inclined surface are disposed on opposite surfaces of the slider. The first limiting surface is disposed on both sides of the processing execution component placement position. The first inclined surface is configured to press the slider towards the outer mold direction under the extrusion of the upper mold structure, thereby driving the processing execution component to process the junction box to be processed.
[0008] Preferably, the placement position of the processing execution component is L-shaped, and the top of the vertical side of the L-shape of the placement position of the processing execution component is provided with a first inclined surface that slopes towards the base plate. The first limiting surface is provided on both sides of the placement position of the processing execution component, and the horizontal plane where the first limiting surface is located is lower than the horizontal plane where the horizontal side of the L-shape of the placement position of the processing execution component is located.
[0009] Furthermore, the stop block is provided with a second limiting surface that matches the first limiting surface, and the second limiting surface is configured to restrict the slider from moving along the direction set by the second limiting surface.
[0010] Furthermore, the upper mold structure includes an upper mold base and an upper pad. The upper pad is disposed on the upper mold base and has an insert block on it. The insert block is correspondingly disposed with the slider. The insert block has a second inclined surface. The first inclined surface and the second inclined surface are matched and disposed. The second inclined surface is used to contact and squeeze the slider with the first inclined surface. The upper pad has a guide post, which is matched with the guide sleeve.
[0011] Furthermore, the lower pad is provided with a tapping structure, which is an in-mold tapping machine, and is configured to tap the bottom and side ears of the junction box to be processed.
[0012] On the other hand, this utility model also provides an automatic processing device for junction boxes, including an automatic processing mold for junction boxes as described above, a drive mechanism connected to the junction box mold to drive the junction box mold to perform opening, closing or forming actions, and a robot arm for performing junction box blank picking and placing, processing part transfer or finished product unloading operations during junction box processing.
[0013] This utility model has the following beneficial effects:
[0014] (1) This utility model greatly simplifies the production process by cooperating with the robotic arm for automatic gripping operations, reduces the coordination links between personnel and equipment, and avoids production interruptions caused by differences in operating rhythm and equipment connection delays; at the same time, it eliminates the need for multiple independent machines to process in steps, shortens the product processing cycle, effectively meets the needs of large-scale and high-efficiency production, and significantly improves overall production efficiency.
[0015] (2) This utility model utilizes a side slider structure, which allows waste generated during product processing to fall freely downwards automatically, eliminating the need for workers to manually clean it during production breaks. This avoids interference with the continuity of the production process caused by cleaning actions, reduces the extra labor load on workers, and further optimizes the production experience and process efficiency.

[0022] 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.
[0023] like Figure 1 As shown, this utility model provides an automatic processing mold for a junction box, including an upper mold structure 1 and a lower mold structure 2. The lower mold structure 2 includes a placement plate 21, and multiple base plates 22 are provided along the circumferential direction on the placement plate 21. Placement blocks 23 are provided on the base plates 22. Each placement block 23 has an outer mold 24 on its top that perfectly matches the shape and size of the junction box to be processed. The outer side wall of the outer mold corresponds to the processing structure 3 of the processing station of the junction box. The upper mold structure 1, which is matched with the lower mold structure 2, moves vertically downward under the action of a driving device to achieve precise matching with the lower mold structure 2 and to push the processing structure 3 to perform processing actions.
[0024] The lower mold structure 2 further includes a lower mold base 25, a lower pad 26, and a fixing plate 27. The lower pad 26 is fixed on the lower mold base 2. The fixing plate 27 is evenly distributed between the lower pad 26 and the placement plate 21. The placement plate 21 is provided with a positioning block 211 and a guide sleeve 28. The placement plate 21 is also provided with a first support column 29, which is used to support the upper mold structure 1.
[0025] like Figure 2 As shown, the processing structure 3 includes a stop block 31, a slider 32, a stop block 33, and a processing execution component 34. The processing execution component 34 is disposed on the slider 32, which is disposed on the outer side wall of the corresponding outer mold to be processed. The slider 32 is slidably connected to the base plate 22. The stop block 31 is fixed on the placement plate 21 to limit the position of the slider 32. The slider 32 is disposed between the stop block 31 and the outer mold 24. The stop block 33 is fixed on the base plate 22 and located on both sides of the slider 32.
[0026] The processing execution component 34 includes a long side cutter, a short side cutter, a corner cutter, a knockout punch, and a bending punch.
[0027] like Figure 3 As shown, the slider 32 is provided with a processing execution component placement position 321, a first inclined surface 322, and a first limiting surface 323. The processing execution component placement position 321 and the first inclined surface 322 are disposed on opposite surfaces of the slider 32. The first limiting surface 323 is disposed on both sides of the processing execution component placement position 321. The first inclined surface 322 is configured to press the slider 32 toward the outer mold 24 under the extrusion of the upper mold structure 1, thereby driving the processing execution component 34 to process the junction box to be processed. By utilizing the side slider structure, the waste generated during product processing can automatically fall freely downwards, eliminating the need for workers to manually clean it during production breaks. This avoids the interference of cleaning actions on the continuity of the production process and reduces the additional labor load of workers, further optimizing the production experience and process efficiency.
[0028] like Figure 4 As shown, the stop block 33 is provided with a second limiting surface 331 that matches the first limiting surface. The second limiting surface 331 is configured to restrict the slider 32 to move along the direction set by the second limiting surface 331.
[0029] like Figure 5As shown, the upper mold structure 1 includes an upper mold base 11 and an upper pad 12. The upper pad 12 is disposed on the upper mold base 11. An insert block 13 is provided on the upper pad 12, corresponding to the slider 32. The insert block 13 has a second inclined surface 131, and the first inclined surface 322 and the second inclined surface 131 are matched. The second inclined surface 131 is used to contact and compress the slider 32 with the first inclined surface 322. A guide post 121 is provided on the upper pad 12, matching the guide sleeve 28. A second support post 122 is provided on the upper pad 12, corresponding to the first support post 29.
[0030] The lower pad is equipped with a tapping structure 4, which is an in-mold tapping machine. This tapping structure is configured to tap the bottom and side ears of the junction box to be machined. The in-mold tapping machine is an existing structure, comprising a press slide, a lead screw, internal gears, and a tapping pin. When the upper mold structure moves downwards, the press slide moves vertically downwards, causing the lead screw to rotate. The rotation of the lead screw drives the internal gears of the tapping machine, which in turn transmit the rotation of the tapping pin to complete the tapping. This equipment uses the movement of the press slide to drive the lead screw-gear mechanism, converting the reciprocating motion into the helical motion of the tapping pin, and achieving chip-free machining using a pressing tap.
[0031] like Figure 6 As shown, this utility model has a fourteenth workstation, wherein the first workstation flips the junction box to be processed into the direction required by the second workstation (not shown in the figure, but operated by a robotic arm);
[0032] The second station 62 cuts the long side of one side of the junction box to be processed and makes knockout holes;
[0033] The third workstation 63 cuts the long side of the other side of the junction box to be processed and makes knockout holes;
[0034] The fourth workstation 64 cuts the two short sides of the junction box to be processed;
[0035] The fifth workstation 65 cuts the four corners of the junction box to be processed;
[0036] The sixth workstation 66 makes knockout holes on the short side of the junction box to be processed.
[0037] The seventh station 67 makes knock-out holes on the short side of the other side of the junction box to be processed.
[0038] The eighth station 68 makes knockout holes on the long side of the junction box to be processed.
[0039] The ninth station 69 makes knockout holes on the long side of the other side of the junction box to be processed;
[0040] The tenth workstation 610 folds one side of the junction box to be processed into an ear;
[0041] The eleventh workstation 611 will fold the lug on the other side of the junction box to be processed.
[0042] The twelfth station 612 taps the side ears of the junction box to be processed;
[0043] The thirteenth station 613 taps the bottom of the junction box to be processed;
[0044] The fourteenth station removes the junction box to be processed (not shown in the figure, but operated by a robotic arm);
[0045] The eleventh and twelfth stations employ an in-mold tapping machine, which completes tapping by rotating the tapping pins at the two stations via a lead screw.
[0046] In this configuration, the processing execution component placement positions of the sliders at the second, third, fourth, sixth, seventh, eighth, ninth, and tenth workstations are L-shaped. The processing execution component is placed on the horizontal side of the L-shaped placement position. The top of the vertical side of the L-shaped placement position is provided with a first inclined surface that slopes towards the base plate. The first limiting surface is located on both sides of the processing execution component placement position. The horizontal plane where the first limiting surface is located is lower than the horizontal plane where the horizontal side of the L-shaped placement position is located. In the initial state, the slider is in contact with the stop block. When the upper module moves vertically downward under the action of the driving device, the insert block contacts the first inclined surface, continuously pressing against the slider and driving the processing execution component to move towards the junction box to be processed until the cutting is completed. During the movement of the slider, the stop block restricts its direction of movement.
[0047] Preferably, depending on the processing situation, the outer mold is provided with a support column 241 to support the long side and short side of the junction box to be processed. For example, in the third station, a support column is provided on the outer mold on the other side where the processing execution component is located to support the long side cut by the second processing station. The same applies to other stations.
[0048] In addition, this utility model also provides an automatic processing device for junction boxes, including an automatic processing mold for junction boxes as described above, a drive mechanism connected to the junction box mold to drive the mold to perform opening, closing or forming actions, and a robot arm for performing junction box blank picking, processing part transfer or finished product unloading operations during junction box processing. Each station is equipped with a robot arm for moving the junction box to be processed to the next processing station. The robot arm can also rotate to adjust the orientation of the junction box. For example, from the second station to the third station, the robot arm first needs to grip the junction box to be processed at the second station, then move it to the third station, then rotate it to flip the two sides of the junction box, and finally place the junction box to be processed on the third station. By coordinating with the robot arm for automatic gripping operations, the production process is greatly simplified, reducing the coordination between personnel and equipment, and avoiding production interruptions caused by differences in operating rhythms or equipment connection delays. At the same time, it eliminates the need for multiple independent machines to process in steps, shortening the product processing cycle, effectively meeting the needs of large-scale and high-efficiency production, and significantly improving overall production efficiency.
