[0002] A body scale is an automated weighing device used to weigh people or goods. It is assembled from multiple parts. During assembly, the scale's feet and battery cells need to be manually placed into the base shell, and then the base shell is placed into the battery cells and the heat-fused individual components. After processing, they are manually removed. Fixing the battery cells and scale feet onto the base shell requires three workers, increasing labor costs. Furthermore, the repetitive manual work increases labor intensity and makes it impossible to guarantee assembly accuracy, thus failing to meet production requirements.

[0058] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0059] like Figures 1 to 16 As shown, this embodiment provides an automatic assembly equipment for a body scale. The automatic assembly equipment includes a frame 1, a bottom shell stacking conveyor 2, a turntable device 3, a vibratory feeder device 4, a moving module 5, and a heat-melting device 6. The bottom shell stacking conveyor 2 is mounted on the frame 1 and is used to separate stacked bottom shells 100 layer by layer and push the bottom shells 100 to the battery cell bottom shell assembly station. The turntable device 3 is located on one side of the bottom shell stacking conveyor 2 and is used to transfer battery cells 300 to the battery cell bottom shell assembly station and assemble them with the bottom shells 100. The vibratory feeder device 4 is used to provide scale feet 200. The moving module 5 is located on one side of the vibratory feeder device 4 and downstream of the battery cell bottom shell assembly station. The moving module 5 is used to transfer the scale feet 200 supplied by the vibratory feeder device 4 and assemble them onto the bottom shells 100. The heat-melting device 6 is used to heat-melt the scale feet 200 inside the bottom shells 100.

[0060] Specifically, in this embodiment, the bottom shell stacking conveyor 2 can push the stacked bottom shells 100 one by one to the battery cell bottom shell assembly station. The turntable device 3 transfers the battery cells 300 provided by the worker to the battery cell bottom shell assembly station and installs the battery cells 300 into the bottom shell 100. Then, the bottom shell 100 containing the battery cells 300 moves to the bottom of the moving module 5. The moving module 5 transfers the weighing feet 200 supplied by the vibratory feeder device 4 onto the bottom shell 100. The bottom shell 100 containing the battery cells 300 and the weighing feet 200 continues to move to the bottom of the hot-melt device 6. The hot-melt device 6 hot-melts the weighing foot positioning post of the weighing feet 200 so that the weighing feet 200 can be fixed on the bottom shell 100, ensuring the installation stability of the weighing feet 200 on the bottom shell 100. This invention requires only one person to load the battery cell 300 into the turntable device 3, resulting in low labor intensity and low labor costs. Both the battery cell 300 and the weighing foot 200 are automatically loaded into the bottom shell 100, achieving a high degree of automation and ensuring production efficiency. Furthermore, by using the heat-melting device 6 to heat-melt the weighing foot positioning post of the weighing foot 200, the weighing foot 200 can be fixed onto the bottom shell 100, ensuring the stability of the weighing foot 200 on the bottom shell 100.

[0061] Optionally, a guide slide plate 11 is provided on the top of the frame 1, and the bottom shell 100 is stacked on the guide slide plate 11. The guide slide plate 11 is used to guide and transport the bottom shell 100. The bottom shell stacking and conveying device 2 includes a shell support drive assembly 21, a shell push drive assembly 22 and a first positioning post 23 mounted on the guide slide plate 11. The first positioning post 23 is used to limit the offset of the stacked bottom shell 100 in the horizontal plane. The shell support drive assembly 21 can support the bottom shell 100 stacked on the bottom second layer. The shell push drive assembly 22 is used to push the bottom shell 100 stacked on the bottom first layer to the cell bottom shell assembly station.

[0062] Specifically, the guide slide plate 11 extends along the Y-axis, and a guide groove is formed on the guide slide plate 11 along the Y-axis. The two sides of the bottom shell 100 abut against the sidewalls of the guide groove, thereby limiting the rotation of the bottom shell 100 and ensuring that the bottom shell 100 can only move in the direction of the extension of the guide groove. The stacked bottom shells 100 are placed on the guide slide plate 11. First positioning posts 23 are provided on all four sides of the bottom shell 100 to accurately position the bottom shell 100. The shell support drive assembly 21 includes a first cylinder 211 and a support plate 212, and the shell push drive assembly 22 includes a second cylinder 221 and a push plate 222. The shell support drive assembly 21 can be set in two, three, or four sets. The shell support drive assembly 21 is provided on both sides of the guide groove. The first cylinder 211 can move along the X-axis. The drive plate 212 presses against the bottom shell 100 stacked on the second layer, thus supporting the second and higher layers of bottom shell 100. The second cylinder 221 drives the push plate 222 along the Y-axis to push the bottom shell 100 stacked on the first layer. Since the second and higher layers of bottom shell 100 are all supported by the shell support drive assembly 21 and limited by the first positioning post 23, the stacked bottom shell 100 will not collapse, and other bottom shells 100 will not flow downstream with the bottom first layer of bottom shell 100. After the bottom first layer of bottom shell 100 is pushed away, the first cylinder 211 drives the drive plate 212 away from the bottom shell 100, and the stacked bottom shell 100 falls into the guide groove. The first cylinder 211 drives the drive plate 212 again to press against and support the bottom second layer of bottom shell 100, and the second cylinder 221 drives the push plate 222 again to push the bottom first layer of bottom shell 100 downstream. This process is repeated.

[0063] Optionally, a sensor for detecting the bottom shell 100 is provided below the first positioning post 23. The sensor can control the operation of the shell support drive assembly 21 and the shell push drive assembly 22.

[0064] Optionally, a cell loading station is provided on one side of the cell bottom shell assembly station, and a protective cover 7 is provided on the cell loading station, with a cell storage slot 71 on the protective cover 7.

[0065] Specifically, the protective cover 7 includes a cover body 72 and a protective baffle 73. The cover body 72 is positioned above the turntable device 3. A battery cell storage slot 71 is located on the top of the cover body 72 and is used to store battery cells 300. A clearance slot 74 is also provided on the top of the cover body 72. Through the clearance slot 74, the worker can insert the battery cells 300 stored in the battery cell storage slot 71 into the turntable device 3 located directly below the clearance slot 74. The cover body 72 can prevent the worker from being hit by the turntable device 3, ensuring the worker's operational safety. The protective baffle 73 is provided around the edge of the cover body 72 near the guide slide plate 11 to separate the worker from other parts on the side of the guide slide plate 11, preventing the worker from being hit and ensuring the worker's operational safety.

[0066] Optionally, the turntable device 3 includes a first rotary drive 31, a positioning fixture 32, a first elastic member 33, and a first lifting drive assembly 34. The first lifting drive assembly 34 is installed inside the protective cover 7. The positioning fixture 32 is installed at the output end of the first rotary drive 31. The first rotary drive 31 is used to drive the positioning fixture 32 to reciprocate between the battery cell bottom shell assembly station and the battery cell insertion station. The first elastic member 33 is disposed at the bottom of the positioning fixture 32. The first lifting drive assembly 34 is used to lift the positioning fixture 32 to the top of the protective cover 7. The positioning fixture 32 inserts the battery cell 300 into the top of the protective cover 7. The first elastic member 33 is connected to the positioning fixture 32 and is used to drive the positioning fixture 32 to reset.

[0067] Specifically, the first lifting drive assembly 34 is fixedly installed on the frame 1. The first lifting drive assembly 34 includes a first lifting cylinder 341 and a first support plate 342. The first elastic element 33 is a spring, and the first rotary drive component 31 is a rotary cylinder. A rotary plate 311 is provided at the output end of the rotary cylinder. Positioning fixtures 32 are respectively provided at both ends of the rotary plate 311. The rotary cylinder can drive the two positioning fixtures 32 to reciprocate between the battery cell bottom shell assembly station and the battery cell installation station through the rotary plate 311. A first lifting rod 38 is respectively passed through both ends of the rotary plate 311. The top end of the first lifting rod 38 is fixedly connected to the positioning fixture 32. The first elastic element 33 is sleeved on the outer periphery of the first lifting rod 38, and the top end of the first elastic element 33 is connected to the rotary plate 311. The bottom end of the elastic element 33 is connected to the first lifting rod 38. When the unloaded positioning fixture 32 is driven by the rotating plate 311 to the underside of the clearance groove 74, the first lifting cylinder 341 drives the first support plate 342 upward. The first support plate 342 lifts the first lifting rod 38 from the bottom. The first elastic element 33, which is sleeved on the outer periphery of the first lifting rod 38, is compressed. The first lifting rod 38 drives the positioning fixture 32 through the clearance groove 74 and rises to the top of the cover 72. The worker can conveniently and quickly insert the battery cell 300 into the positioning fixture 32. After the battery cell 300 is inserted into the positioning fixture 32, the first lifting cylinder 341 drives the first support plate 342 away from the first lifting rod 38. The first elastic element 33 returns to its original state and pushes the first lifting rod 38 and the positioning fixture 32 back to their original positions.

[0068] Optionally, the turntable device 3 further includes a positioning drive assembly 35, a second lifting drive assembly 36, and a third lifting drive assembly 37. The second lifting drive assembly 36 and the third lifting drive assembly 37 are both located below the battery cell bottom shell assembly station. The second lifting drive assembly 36 is used to lift the positioning fixture 32 to contact the bottom shell 100, and the third lifting drive assembly 37 is used to insert the battery cell 300 installed in the positioning fixture 32 into the bottom shell 100. The positioning drive assembly 35 is used to limit the rotation of the positioning fixture 32.

[0069] Specifically, the second lifting drive assembly 36 includes a second lifting cylinder 361 and a second support plate 362; the third lifting drive assembly 37 includes a third lifting cylinder 371 and a second lifting rod 372; and the positioning drive assembly 35 includes a first positioning cylinder 351 and a positioning rod 352. When the positioning fixture 32 carrying the battery cell 300 moves to below the battery cell bottom shell assembly station, the first positioning cylinder 351 drives the positioning rod 352 to insert into the side wall of the rotating plate 311, ensuring that the positioning fixture 32 can be accurately positioned below the battery cell bottom shell assembly station. The second lifting cylinder 361 drives the third lifting cylinder 371 to insert the positioning rod 352 into the side wall of the rotating plate 311. The second support plate 362 rises, and the second support plate 362 lifts the first lifting rod 38 from the bottom. The first elastic element 33, which is sleeved on the outer periphery of the first lifting rod 38, is compressed. The first lifting rod 38 drives the positioning fixture 32 to rise and contact the bottom shell 100. The third lifting cylinder 371 drives the second lifting rod 372 to rise. The second lifting rod 372 inserts the battery cell 300 installed in the positioning fixture 32 into the bottom shell 100. Then the third lifting drive assembly 37 and the second lifting drive assembly 36 reset, and the first elastic element 33 returns to its original state, pushing the first lifting rod 38 and the positioning fixture 32 back to their original positions.

[0070] Specifically, the guide slide plate 11 has an avoidance through hole, which is connected to the guide slide groove. The positioning fixture 32 passes through the avoidance through hole and abuts against the bottom shell 100.

[0071] Optionally, a second positioning cylinder 39 and a positioning plate 310 are provided above the clearance through hole. The second positioning cylinder 39 can drive the positioning plate 310 to move downward and abut against the bottom shell 100, so as to prevent the bottom shell 100 from being lifted off the guide slide plate 11 by the second lifting drive component 36 or the third lifting drive component 37.

[0072] Optionally, the battery cell bottom shell assembly station is equipped with a battery cell bending drive device 8, which is used to bend the battery cells 300 inserted into the bottom shell 100.

[0073] Specifically, the battery cell bending drive device 8 includes a bending cylinder 81 and a bending component 82. The bending cylinder 81 is inclined, and the bending component 82 is installed at the output end of the bending cylinder 81. The bending cylinder 81 drives the bending component 82 to bend the battery cell 300 on the bottom shell 100, and the battery cell 300 is in fixed contact with the battery cell.

[0074] Optionally, a weighing foot bottom shell assembly station is provided downstream of the battery cell bottom shell assembly station. A weighing foot correction device 9 is provided between the weighing foot bottom shell assembly station and the vibratory feeder device 4. The weighing foot correction device 9 is used to correct the weighing foot 200 clamped on the moving module 5.

[0075] Specifically, the scale foot correction device 9 includes a correction cylinder 91 and a correction block 92. The correction block 92 is installed at the output end of the correction cylinder 91. The correction cylinder 91 can drive the correction block 92 to correct the edge of the scale foot 200 located on the moving module 5.

[0076] Optionally, the moving module 5 includes a lead screw drive assembly 51, a lifting drive assembly 52, a stripping drive assembly 53, and a magnetic suction assembly 54. The lifting drive assembly 52 is installed at the output end of the lead screw drive assembly 51, and the magnetic suction assembly 54 and the stripping drive assembly 53 are both installed at the output end of the lifting drive assembly 52. ​​The magnetic suction assembly 54 is used to attract the weighing feet 200 supplied by the vibratory feeder device 4, and the stripping drive assembly 53 is used to drive the weighing feet 200 to detach from the magnetic suction assembly 54.

[0077] Specifically, when the bottom shell 100 containing the battery cell 300 moves to below the moving module 5, the screw drive assembly 51 drives the lifting drive assembly 52 to move to the output line of the vibratory feeder 4. The lifting drive assembly 52 drives the magnetic suction assembly 54 to move down to attract the weighing foot 200 located on the output line of the vibratory feeder 4. The lifting drive assembly 52 drives the magnetic suction assembly 54 to rise with the weighing foot 200. The screw drive assembly 51 drives the lifting drive assembly 52 to move above the bottom shell 100. The lifting drive assembly 52 drives the magnetic suction assembly 54 to bring the weighing foot 200 closer to the bottom shell 100. The unloading drive assembly 53 drives the weighing foot 200 to detach from the magnetic suction assembly 54, and the weighing foot 200 falls into the bottom shell 100.
