The ends of the left side panel and the right side panel are riveted with reinforcements to improve the overall structural strength of the housing. Specifically, Figure 1 and Figure 2As shown, the riveting equipment includes a side panel positioning mechanism 1, a reinforcement riveting mechanism 2, and a reinforcement conveying mechanism 3. The side panel positioning mechanism 1 is used to position the side panel 100 in the riveting position. The reinforcement riveting mechanism 2 includes a riveting drive assembly 21 and a riveting clamp assembly 22. The riveting clamp assembly 22 is connected to the riveting drive assembly 21. The riveting clamp assembly 22 includes a riveting punch 221, a riveting die 222, and a punch driver 223. The riveting punch 221 and the riveting die 222 are arranged opposite to each other. The punch driver 223 is connected to the riveting punch 221. The riveting die 222 is provided with a reinforcement positioning portion 23. The reinforcement conveying mechanism 3 is used to convey the reinforcement 200 and cooperate with the riveting drive assembly 21 to place the reinforcement 200 in the reinforcement positioning portion 23. The riveting drive assembly 21 is used to drive the rivet clamp assembly 22 to move to the riveting position, so that the riveting punch 221 and the riveting die 222 are placed on both sides of the end fold of the side panel 100, and the reinforcement 200 is fit with the end fold of the side panel 100. The punch driving component 223 is used to drive the riveting punch 221 to move toward the riveting die 222 so that the reinforcement 200 is riveted to the end fold of the side panel 100.

[0057] In certain embodiments, the reinforcement member conveying mechanism 3 comprises a storage assembly 31, a first reinforcement member transfer assembly 32, a positioning turnover assembly 33 and a second reinforcement member transfer assembly 34. The first reinforcement member transfer assembly 32 is arranged between the storage assembly 31 and the positioning turnover assembly 33, and the second reinforcement member transfer assembly 34 is arranged between the positioning turnover assembly 33 and the reinforcement member riveting mechanism 2.

The storage assembly 31 is set and can store quantitative reinforcement 200, and continuous production can be realized. The first reinforcement member moving assembly 32 , the positioning and flipping assembly 33 and the second reinforcement member moving assembly 34 cooperate to realize automatic loading of the reinforcement member 200 and put the reinforcement member 200 into the state required for riveting.

[0058] Alternatively, as Figure 3As shown, the material storage assembly 31 includes a material storage platform 311, a material storage rotary drive member 312, and a stacking jig 313. The stacking jig 313 is used to horizontally stack the reinforcement members 200. The material storage platform 311 is provided with at least two stacking jigs 313, and the at least two stacking jigs 313 are spaced apart along the edge of the material storage platform 311. The material storage rotary drive member 312 is used to drive the material storage platform 311 to rotate so that the stacking jig 313 is placed on the side where the first reinforcement member transfer assembly 32 is provided. The plurality of stacking jigs 313 are provided to increase the number of reinforcement members 200 that can be loaded at one time, extend the production cycle, reduce the frequency of downtime for loading, and thus improve production efficiency. When it is detected that there is no reinforcement member 200 in the stacking jig 313 placed on the side of the first reinforcement member transfer assembly 32, the material storage rotary drive member 312 drives the material storage platform 311 to rotate so that the stacking jig 313 with the reinforcement member 200 is placed on the side where the first reinforcement member transfer assembly 32 is provided. The rotation angle of the material storage platform 311 can be a preset angle, wherein the preset angle can be 90° or 180°, which is not specifically limited here, and is set according to the number and position of the stacking tools 313. The rotation angle of the material storage platform 311 can also be detected by a set sensor. After detecting that the stacking tools 313 have moved into place, the material storage rotary drive 312 stops operating. The material storage rotary drive 312 can be a rotary cylinder or a motor, which is not specifically limited here.

[0059] Because the reinforcement 200 is an elongated structure, to facilitate positioning of the reinforcement 200 and facilitate gripping of the reinforcement 200 by the first reinforcement transfer assembly 32, the stacking tool 313 includes at least one set of limiting assemblies 3131. Each set of limiting assemblies 3131 includes two rows of spaced limiting posts 31311, with each row of limiting posts 31311 having at least two spaced limiting posts 31311. The reinforcement 200 is stacked between the two rows of limiting posts 31311, with the stacked reinforcement 200 height being less than or equal to the height of the limiting posts 31311. A limiting post 31311 is provided between the two rows of limiting posts 31311, which is configured to abut against the end of the reinforcement 200. Optionally, the stacking tool 313 includes multiple limiting assemblies 3131 to increase the number of reinforcements 200 that can be loaded at one time.

[0060] For example, two stacking fixtures 313 are provided on the material storage platform 311. Each stacking fixture 313 includes three sets of limit assemblies 3131. A baffle plate 314 is provided between the two stacking fixtures 313. By manually filling each stacking fixture 313 with reinforcements 200, a production time of 18 minutes can be achieved.

[0061] Alternatively, as Figure 4As shown, the first reinforcement member transfer assembly 32 includes a first vertical transfer driver 321, a first horizontal transfer driver 322, and a first transfer clamping member 323.

The fixing member secures the reinforcement member 200 to the flipping member 333 to prevent the reinforcement member 200 from falling when the flipping member 333 switches from a horizontal position to a vertical position.

[0064] The flip driving member 334 is a flip cylinder, which is arranged on the side of the support base 331.

[0065] The flip member 333 includes a flip seat 3331 connected to the flip driving member 334. The flip seat 3331 is provided with a first stopper 3332 and a second stopper 3333.

The fixing member includes a magnetic element disposed on the flip seat 3331. The magnetic element attracts the reinforcement member 200 but does not affect the force applied by the first positioning portion 3321 and the second positioning portion 3322 to the reinforcement member 200 to adjust its position.

[0066] The first positioning part 3321 includes a first positioning cylinder 33211 and a first positioning plate 33212.

The second transfer clamp 343 is used to clamp the reinforcement 200 on the positioning and flipping assembly 33. The second horizontal transfer drive member 341 drives the third horizontal transfer drive member 342 to move along the first direction, so that the second transfer clamping member 343 moves toward the positioning and flipping assembly 33, and the second transfer clamping member 343 clamps the reinforcement 200 in a vertical state on the positioning and flipping assembly 33. After the second horizontal transfer drive member 341 drives the third horizontal transfer drive member 342 to move in a direction away from the positioning and flipping assembly 33, the third horizontal transfer drive member 342 drives the second transfer clamping member 343 to move along the second direction toward the reinforcement positioning portion 23, and cooperates with the riveting drive assembly 21 to enable the second transfer clamping member 343 to install the reinforcement 200 on the reinforcement positioning portion 23. After the reinforcement 200 is placed on the reinforcement positioning portion 23, the third horizontal transfer drive 342 drives the second transfer clamp 343 to move along the second direction away from the reinforcement positioning portion 23, the second horizontal transfer drive 341 drives the third horizontal transfer drive 342 to move along the first direction, and the second transfer clamp 343 continues to clamp the reinforcement 200 in a vertical state on the positioning flip assembly 33.

[0069] In some embodiments, as Figure 1 and Figures 8 to 10 As shown, there are two rivet clamp assemblies 22, and the side panel positioning mechanism 1 is used to position the two side panels 100. Each rivet clamp assembly 22 is respectively provided with a reinforcement conveying mechanism 3. The reinforcement conveying mechanism 3 is used to convey the reinforcement 200 to the reinforcement positioning portion 23 of the corresponding rivet clamp assembly 22. The riveting drive assembly 21 is used to drive the two rivet clamp assemblies 22 to move at the same time, so that the riveting punch 221 and the riveting die 222 are placed on both sides of the end fold of the corresponding side panel 100, and the reinforcement 200 is fit with the end fold of the corresponding side panel 100, so as to realize the simultaneous riveting of the two side panels 100 and the two reinforcements 200. The two side panels 100 can be the left and right panels of the same shell, thereby improving the production efficiency of the shell.

[0070] Optionally, the riveting drive assembly 21 includes a first riveting drive 211, a second riveting drive 212, and a third riveting drive 213. The second riveting drive 212 is connected to the first riveting drive 211, and the first riveting drive 211 is used to drive the second riveting drive 212 to move between the reinforcement conveying mechanism 3 and the riveting position. The third rivet driver 213 is connected to the second rivet driver 212, and the second rivet driver 212 is used to drive the third rivet driver 213 to move in the vertical direction. The two rivet clamp assemblies 22 are connected to the third rivet driver 213, and the third rivet driver 213 is used to drive the two rivet clamp assemblies 22 to approach each other, so that when the first rivet driver 211 drives the second rivet driver 212 to move toward the riveting position, the rivet punch 221 or the rivet die 222 can avoid the end folding edge of the side panel 100. The third rivet driver 213 is used to drive the two rivet clamp assemblies 22 away from each other, so that the rivet punch 221 and the rivet die 222 are located on both sides of the end folding edge of the corresponding side panel 100.

[0071] When the second transfer clamp 343 moves to the gap between the upper and lower riveting punches 221 and the reinforcement 200 is placed between the riveting punch 221 and the riveting die 222, the first riveting drive 211 drives the riveting clamp assembly 22 to move the riveting die 222 toward the reinforcement 200, so that the positioning pin is inserted into the positioning hole. After the second transfer clamping member 343 moves away from the rivet clamp assembly 22, the third rivet driving member 213 drives the two rivet clamp assemblies 22 to approach each other, and the second rivet driving member 212 drives the third rivet driving member 213 to move in the vertical direction so that the reinforcement 200 corresponds to the position to be riveted of the side panel 100, and the first rivet driving member 211 drives the rivet clamp assembly 22 to move toward the riveting position, and the riveting punch 221 or the riveting die 222 can avoid the end folding edge of the side panel 100. The third rivet driving member 213 drives the two rivet clamp assemblies 22 away from each other, so that the riveting punch 221 and the riveting die 222 are located on both sides of the end folding edge of the corresponding side panel 100, and the reinforcement 200 is fitted with the end folding edge of the side panel 100. The punch driving member 223 drives the rivet punch 221 to move toward the riveting die 222, so that the reinforcement 200 is riveted to the end folding edge of the side panel 100.

[0072] The first rivet driving component 211 may be a screw-nut structure, a linear motor or a cylinder, and the second rivet driving component 212 may be a screw-nut structure, a linear motor or a cylinder.

[0073] The third riveting drive component 213 includes a lead screw, which is provided with two sections of threads with different rotation directions. A nut is screwed onto each section of the thread, and each nut is connected to a rivet clamp assembly 22. One end of the lead screw is rotated and fixed, and the other end of the lead screw is connected to a drive motor. The drive motor drives the lead screw to rotate, so that the two nuts are moved closer to or away from each other, and then the two rivet clamp assemblies 22 are moved closer to or away from each other.

[0074] The punch driving member 223 can be a linear motor or a cylinder.

[0075] In some embodiments, as Figure 11 and Figure 12 As shown, the side panel positioning mechanism 1 includes a side panel positioning platform 11, and two side panel support seats 12 are spaced apart on the side panel positioning platform 11. The side panel support seats 12 are respectively used to support the side panels 100, and the ends of the two side panel support seats 12 on the opposite sides are respectively provided with side positioning members 13, and the side positioning members 13 are used to position one side of the side panel 100. The sides facing each other of the two side panel support seats 12 are respectively provided with bottom positioning members 14, and the bottom positioning members 14 are used to position the surface of the side panel 100 close to the side panel support seat 12. The end of the side panel support seat 12 facing away from the side positioning member 13 is provided with an end positioning member 15, and the end positioning member 15 is used to position the end face of the side panel 100. The side positioning member 13 is arranged toward the rivet clamp assembly 22. The side panel 100 is placed vertically on the side panel support seat 12, and the side positioning members 13, the bottom positioning members 14 and the end positioning members 15 cooperate to position the side panel 100 on the side panel support seat 12. When the reinforcement 200 is riveted to the side panel 100, due to the limitation of the end positioning members 15, the side panel 100 will not be displaced, and the quality of the riveting between the reinforcement 200 and the side panel 100 can be guaranteed.

[0076] The side positioning member 13 includes a side positioning plate 131 . A plurality of vacuum suction cups 132 are provided on the side positioning plate 131 . The plurality of vacuum suction cups 132 are distributed along the width direction of the side plate 100 .

[0077] The bottom positioning member 14 includes a bottom positioning drive cylinder 141 and a bottom positioning block 142. The piston rod end of the bottom positioning drive cylinder 141 is hingedly connected to one end of the bottom positioning block 142, and the other end of the bottom positioning block 142 is hingedly connected to the side panel positioning platform 11. The bottom positioning drive cylinder 141 drives the bottom positioning block 142 to rotate, so that the bottom positioning block 142 abuts against the side panel 100 or moves away from the side panel 100.

[0078] The end positioning member 15 includes an end positioning driving cylinder 151 and an end positioning block 152 .

[0082] 3. The first reinforcement member transfer assembly 32 clamps the reinforcement member 200 on the stacking tooling 313 and transfers the reinforcement member 200 to the flip seat 3331 of the positioning flip assembly 33 which is in a horizontal state. The first positioning portion 3321 and the second positioning portion 3322 adjust the position of the reinforcement member 200 so that the side surface of the reinforcement member 200 is in contact with the first stop member 3332 and the end of the reinforcement member 200 is in contact with the second stop member 3333. The fixing member fixes the reinforcement member 200 on the flip seat 3331.

[0083] 4. The flip driving member 334 drives the flip seat 3331 to rotate, so that the flip seat 3331 flips from the horizontal state to the vertical state.

[0084] 5. The second reinforcement member transfer assembly 34 clamps the reinforcement member 200 on the flip seat 3331 and cooperates with the riveting drive assembly 21 to place the reinforcement member 200 on the reinforcement member positioning portion 23 .

[0085] 6.
