[0063] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0064] See also Figures 1-1 to 1-4 , an assembly machine of the present invention includes an assembly machine 100 and a forming machine 200 connected in sequence along a conveying direction;

[0065] The assembly machine 100 includes a disc clamping device 11, a plug feeding device 12, a shell feeding device 13, a lead wire pulling device 16, a detection device 17, a pressing device 14 and a transfer device 15;

[0066] The disc clamping device 11 includes a first turntable 111, a guide member 112 and a plurality of clamping assemblies 113. The first turntable 111 rotates relative to the guide member 112. The plurality of clamping assemblies 113 are all arranged on the first turntable 111.

[0067] The plug feeding device 12, the shell feeding device 13, the lead-pulling device 16, the detection device 17, the pressing device 14 and the transfer device 15 are arranged in sequence around the rotation direction of the first turntable 111. The clamping assembly 113 is used to receive the external plug a from the plug feeding device 12. The clamping assembly 113 is used to receive the external shell b from the shell feeding device 13. The clamping assembly 113 and the guide member 112 are in contact with each other so that the central axis of the external plug a coincides with the central axis of the shell b. The lead-pulling device 16 pulls the lead in the external shell b to a preset length. The detection device 17 is used to detect the lead of the shell b. The pressing device 14 inserts the external plug a into the port of the shell b to form a semi-finished battery c. The transfer device 15 transfers the semi-finished battery c to the forming machine 200.

[0068] The forming machine 200 presses an annular groove on the outer side of the battery semi-finished product c. The annular groove is located at the fitting position between the external rubber plug a and the external shell b. The forming machine 200 folds the top of the shell b with the extruded annular groove inward and presses it onto the upper surface of the rubber plug a.

[0069] Specifically, in this embodiment, the assembly machine 100 needs to complete the production process of inserting the rubber plug a into the shell b to form a semi-finished battery c. A plurality of clamping assemblies 113 are installed on the edge of the first turntable 111 in a ring array state with the central axis of the first turntable 111. The disc clamping device 11 also includes a divider and a flange. The divider drives the first turntable 111 to rotate. The flange is installed below the first turntable 111. The guide 112 is fixed to the flange. The central axis of the guide 112 coincides with the central axis of the first turntable 111. The plug feeding device 12, the shell feeding device 13, the pressing device 14 and the transfer device 15 are arranged in the rotation direction of 111. The plug feeding device 12 inputs the external plug a into the clamping assembly 113, and the shell feeding device 13 inputs the external shell b into the clamping assembly 113. The plug a is located above the shell b. Under the rotation of the first turntable 111, the clamping assembly 113 moves along the guide member 112 so that the central axis of the shell b coincides with the central axis of the plug a. Under the action of the pressing device 14, the plug a is inserted into the open end of the shell b to complete the plugging. The pre-assembly of plug a and shell b forms a semi-finished battery c. Preferably, a lead-pulling device 16 and a detection device 17 are further provided between the shell feeding device 13 and the pressing device 14. The number of the lead-pulling devices 16 is two, and the two lead-pulling devices 16 are arranged at a distance. The lead-pulling device 16 pulls out the core package lead in the shell b, that is, adjusts the position of the core package installed in the shell b in the shell b to ensure the quality of production. Then the detection device 17 checks the core package lead of the shell b, collects unqualified plug a and shell b assemblies into a waste box, and closes the battery. The assembled plug a and shell b are transported to the pressing device 14 to complete the assembly and form a semi-finished battery product c. The semi-finished battery product c is transported to the transfer device 15. Under the action of the transfer device 15, the semi-finished battery product c is transferred to the forming machine 200. The forming machine 200 presses an annular groove on the outer side of the semi-finished battery product c. The annular groove is located at the fitting position of the external plug a and the external shell b. The forming machine 200 folds the top of the shell b with the extruded annular groove inward and presses it on the upper surface of the plug a, completing the automated assembly and pressing of the plug a and the shell b into one.

[0070] By providing a disc clamping device 11 consisting of a first turntable 111, a guide member 112 and a plurality of clamping assemblies 113, and an assembly machine 100 consisting of the disc clamping device 11, a plug feeding device 12, a shell feeding device 13, a pressing device 14 and a transfer device 15, the purpose of automatically assembling the outer plug a and the outer shell b into a semi-finished battery product c is achieved. The semi-finished battery product c enters the forming machine 200 under the action of the transfer device 15, thereby improving the degree of production automation, production efficiency and processing accuracy.

[0071] See also Figures 2-1 to 2-7The clamping assembly 113 includes a first mounting plate 1131, a plug clamp 1132, a shell clamp 1133 and a first wheel body 1134. The first mounting plate 1131 is fixed on the lower surface of the first turntable 111, the plug clamp 1132 is arranged on the first mounting plate 1131, the shell clamp 1133 is slidably connected to the first mounting plate 1131 and is located below the plug clamp 1132. The first wheel body 1134 is connected to the plug clamp 1132. The first wheel body 1134 is slidably connected to the guide member 112 so that the central axis of the shell clamp 1133 coincides with or is parallel to the central axis of the plug clamp 1132. Each clamping assembly 113 includes a first mounting plate 1131, a plug clamp 1132, a shell clamp 1133 and a first wheel body 11 34. The first mounting plate 1131 includes two baffles and a base plate. The two baffles are arranged above the base plate and are spaced apart. The two baffles are fixed to the lower surface of the first turntable 111 by screw connectors. The plug clamp 1132 is connected to the base plate and is located below the baffle. The plug clamp 1132 is used to clamp the external plug a supplied by the plug feeding device 12. The baffle is used to longitudinally limit the clamped plug a. The shell clamp 1133 is slidably connected to the base plate. The shell clamp 1133 is used to clamp the external shell b supplied by the shell feeding device 13. Then, the first wheel body 1134 moves along the radial direction of the first turntable 111 under the drive of the guide member 2, so that the central axis of the shell b coincides with the central axis of the plug b, completing the positioning of the plug a and the shell b before assembly.

[0072] The clamping assembly 113 also includes a correction block 1135 and a second wheel body 1136 connected to the correction block 1135. The correction block 1135 is located above the plug clamp 1132. The correction block 1135 is slidably connected to the first mounting plate 1131. The second wheel body 1136 is connected to the guide member 112 so that the center axis of the correction block 1135 coincides with or is parallel to the center axis of the plug clamp 1132. The correction block 1135 and the second wheel body 1136 are connected by a connecting rod, and the connecting rod is slidably connected between the two blocks. Under the action of the guide member 112, the second wheel body 1136 makes the center axis of the correction block 1135 coincide with or move away from the center of the plug clamp 1132. A pointed protrusion is provided at the end of the correction block 1135. The center axis of the pointed protrusion is parallel to the center axis of the plug clamp 1132. The pointed protrusion performs leg separation correction on the two core-wrapped leads of the shell b to ensure the qualified rate of subsequent processing quality.

[0073] The guide member 112 includes a first guide surface 1121, a second guide surface 1122 and a notch 1123. The distance between the second guide surface 1122 and the central axis of the guide member 112 is a constant value. The distance between the first guide surface 1121 and the central axis of the guide member 112 changes from small to large and then to small. The notch 1123 is located on the second guide surface 1122 and passes through the second guide surface 1122. The first wheel body 1134 conflicts with the first guide surface 1121, and the second wheel body 1136 conflicts with the second guide surface 1122. Preferably, the distance between the first guide surface 1121 and the central axis of the guide member 112 is greater than the distance between the second guide surface 1122 and the central axis of the guide member 112. The first guide surface 1121 is arc-shaped, and the second guide surface 1122 is arc-shaped. The first guide surface 1121 drives the plug clamp 1132 to move in the radial direction and ensures that the distance between the plug clamp 1132 and the central axis of the guide member 112 is within a preset range. The setting of the second guide surface 1122 makes the correction block 1135 rotate synchronously with the first turntable 111. During the process, the correction block 1135 is relatively stationary relative to the central axis of the guide member 112. When the second wheel body 1136 passes through the notch 1123, the central axis of the correction block 1135 is away from the central axis of the guide member 112 and thus close to the central axis of the plug clamp 1132, thereby correcting the core lead of the shell b and further ensuring the stability of production quality.

[0074] The first guide surface 1121 includes a first arc segment 11211, a second arc segment 11212 and a third arc segment 11213 connected in sequence, the first arc segment 11211 and the third arc segment 11213 are arranged at intervals, the distance from any point of the second arc segment 11212 to the central axis of the guide member 112 is greater than the distance from any point of the first arc segment 11211 to the central axis of the guide member 112, the distance from any point of the second arc segment 11212 to the central axis of the guide member 112 is greater than the distance from any point of the third arc segment 11213 to the central axis of the guide member 112, the distance from the first arc segment 11211 to the central axis of the guide member 112 is gradually changing from small to large, the distance from the second arc segment 11212 to the central axis of the guide member 112 is a constant value, and the distance from the third arc segment 11213 to the central axis of the guide member 112 is gradually changing from large to small, so that the shell clamp 1133 moves radially at a uniform speed.

[0075] The first rotating disk 111 is provided with a first elongated hole 1111 and a second elongated hole 1112. The length direction of the first elongated hole 1111 is arranged along the radial direction of the first rotating disk 111, and the length direction of the second elongated hole 1112 is arranged along the radial direction of the first rotating disk 111.

The first limiting member 1137 is fixedly connected to the shell clamp 1133, and the first limiting member 1137 is slidably connected to the first long hole 1111. The second limiting member 1138 is fixedly connected to the correction block 1135, and the second limiting member 1138 is slidably connected to the second long hole 1112, ensuring that the shell clamp 1133 reciprocates within a preset distance, ensuring that the correction block 1135 reciprocates within a preset distance, and further ensuring the safety of production.

A vacuum suction piece 25 is installed on the clamping claw, and when the clamping claw clamps the semi-finished battery product c for correction, the vacuum suction piece 25 synchronously adsorbs the battery. The gas inside the battery semi-finished product c makes the interior of the battery semi-finished product c in a vacuum state, and then the second turntable 21 rotates to transfer the corrected battery semi-finished product c to the waisting station. Preferably, the waisting component 244 and the sealing component 245 are both installed on the second mounting plate 241, and the rotating drive part 242 adopts a servo motor to drive the waisting component 244 and the sealing component 245 to rotate synchronously, respectively realizing the waisting processing and sealing processing of the battery semi-finished product c, and the lifting drive source 243 drives the waisting component 244 and the sealing component 245 to rise and fall, avoiding the collision between the battery semi-finished product c and the waisting component 244 or the sealing component 245 when the second turntable 21 carries the battery semi-finished product c to rotate, thereby improving production safety.
