In the embodiment, the shell feeding device 32 is provided with four groups, each of which includes a vibrating disc 321 and a material carrying device 322. The vibrating disc 321 is used to vibrate the shell so that the front face of the shell faces upward. The material carrying device 322 is used to carry the shell with the front face facing upward to the carrier 312. The shell feeding device 32 vibrates the shell through the vibrating disc 321 so that the front face of the shell faces upward, facilitating subsequent assembly. The material carrying device 322 can carry the shell with the front face facing upward to the carrier 312 to realize the feeding operation.

[0137] Preferably, the vibrating disc 321 is movably arranged along the second direction. Each vibrating disc 321 is arranged on a group of linear slides and is movable along the second direction toward or away from the transfer flow line 31 under the driving of a cylinder or other linear driving mechanism, i.e., when the vibrating disc 321 needs to be fed, it moves away from the transfer flow line 31, and after feeding, it moves toward the transfer flow line 31 to work normally.

[0138] A visual recognition assembly is arranged beside each vibrating disc 321 to guide the material carrying device 322 to take the material. Specifically, after the vibrating disc 321 vibrates once, some of the terminal shell products have the front face facing upward, and some have the back face facing upward. The visual recognition assembly guides the material carrying device 322 to suck the products with the front face facing upward. The products with the back face facing upward continue to vibrate under the action of the vibrating disc 321 until they become products with the front face facing upward.

The second cam structure 425 is rotationally arranged on the second mounting base 421. The second driving mechanism is used for driving the second cam structure 425 to rotate. The second pushing plate assembly 4231 is provided with a receiving groove, which is a second receiving groove 42311. The second receiving groove 42311 is provided with a second follower 426 connected with the second cam structure 425. The second follower 426 is movably arranged in the second receiving groove 42311, so as to drive the second pushing plate assembly 4231 to reciprocate along the second direction.

[0169] The second follower 426 is driven to move in the second receiving groove 42311 by the rotation of the second cam structure 425, so as to realize the reciprocation of the second pushing plate assembly 4231 along the second direction. The structure is simple, and the operation of the second pushing plate assembly 4231 is stable.

[0170] Preferably, the second pressing plate assembly 4232 comprises a plurality of second pressing plates 42321. The plurality of second pressing plates 42321 are plate-shaped structures extending along the second direction. The plurality of second pressing plates 42321 are arranged side by side along the second direction on the side of the second pushing plate assembly 4231 away from the receiving groove. One end of the plurality of second pressing plates 42321 respectively movably extends into the corresponding mold groove on the second pushing mechanism 423. Each second pressing plate 42321 is provided with a profiling pushing head near the compacting and transferring path 4211. The profiling pushing head can match the structure of the shell, so as to stably and uniformly apply force on the shell.

[0171] The first pushing mechanism 422 comprises a pushing assembly 4221 and a pressing assembly 4222. The pressing assembly 4222 is arranged on the two sides of the compacting conveying path 4211 opposite to the pressing plate assembly of the second pushing mechanism 423. The pressing assembly 4222 is movably arranged on the second mounting base 421 along the second direction to extend into or out of the compacting conveying path 4211. The pressing assembly 4222 comprises a pressing main body movably arranged on the second mounting base 421 along the second direction and a pushing pressing plate 42221 arranged on the pressing main body. The pushing pressing plate 42221 is provided with a pushing pressing head 42222. The pushing pressing head 42222 is mounted on the pushing pressing plate 42221. The pushing assembly 4221 is movably arranged on the second mounting base 421 along the vertical direction and located on the side of the pressing assembly 4222 away from the conveying path. The pushing assembly 4221 is drivingly connected with a lifting driving device. The lifting driving device drives the pressing assembly 4222 to lift along the vertical direction. The pushing assembly 4221 is in slope cooperation with the pressing assembly 4222 to drive the pressing assembly 4222 to move along the second direction. The first pushing mechanism 422 drives the pressing assembly 4222 to move along the second direction through the slope cooperation between the pushing assembly 4221 and the pressing assembly 4222 and cooperates with the first pushing mechanism 422 to compact the shell on the shell.

[0172] Specifically, the side of the pushing assembly 4221 facing the pressing assembly 4222 is provided with a slope inclined from top to bottom towards the direction close to the pressing assembly 4222. The side of the pressing assembly 4222 away from the compacting conveying path 4211 is rotatably provided with a roller 42223. The roller 42223 is in rolling contact with the slope. The cooperation between the slope and the roller 42223 realizes the rolling contact and reduces the friction resistance therebetween.

[0173] The first pushing mechanism 422 further comprises a reset assembly 4223 for driving the pressing assembly 4222 to reset for reuse. The reset assembly 4223 comprises a spring. One end of the spring is connected with the pressing assembly 4222. The other end of the spring is connected with the pushing assembly 4221. The spring structure is simple and low in cost. The pushing assembly 4221 can be driven to reset through the contraction force of the spring.

[0174] When the piston rod of the lifting driving device extends to push the pushing assembly 4221 to move upward, the lower part of the slope will be in contact with the roller 42223 and push the pressing assembly 4222 to move towards the compacting conveying path 4211, so that the pushing pressing head 42222 on the pressing assembly 4222 presses the terminal material belt. The compacting operation is cooperated with the second pushing mechanism 423. When the piston rod of the lifting driving device retracts, the pushing assembly 4221 also descends. The upper part of the slope is separated from the roller 42223. The pressing assembly 4222 moves away from the compacting conveying path 4211 under the action of the spring to reset, so that the pushing pressing head 42222 releases the pressing on the terminal material belt.

[0175] As Figures 14-25 shown, the terminal assembly processing line further comprises a cutting device 5 and a welding device 6, which are sequentially arranged along the conveying path, the cutting device 5 is used for cutting off the terminal pieces in the terminal assembly that are unqualified in quality; the welding device 6 is used for welding the two disconnected parts of the terminal assembly. The cutting device 5 can cut off the terminal pieces in the terminal assembly that are unqualified in assembly, and the disconnected terminal assembly is connected by the welding device 6.

[0176] Specifically, as Figures 14-22 shown, the cutting device 5 comprises a support structure 50, a cutting knife assembly 51 and a floating knife block assembly 52 arranged on the support structure 50, the support structure 50 has a cutting movement path 501, the cutting knife assembly 51 is arranged above the cutting movement path 501 and is used for cutting the terminal assembly; the cutting knife assembly 51 is arranged in a lifting manner; the floating knife block assembly 52 comprises a plurality of floating knife blocks, the plurality of floating knife blocks are arranged on one side of the cutting movement path 501 along a first direction, and each floating knife block is independently movable along a second direction to abut against the terminal assembly, and the second direction is perpendicular to the first direction. The cutting device 5 cuts the terminal assembly by the cutting knife assembly 51, and the plurality of floating knife blocks of the floating knife block assembly 52 can limit the terminal assembly at different positions to avoid displacement of the terminal assembly during cutting by the cutting knife assembly 51.

[0177] Specifically, the cutting knife assembly 51 comprises a cutting knife 511, a cutting positioning pin 512 and a cutting knife lifting cylinder 513, the cutting knife lifting cylinder 513 can drive the cutting knife 511 and the cutting positioning pin 512 to synchronously lift relative to the conveying path, and the cutting positioning pin 512 is used for positioning the terminal strip to facilitate cutting of the terminal strip by the cutting knife 511.

[0178] The floating knife block assembly 52 comprises three floating knife blocks, which are a front floating knife block 521, a middle floating knife block 522 and a rear floating knife block 523 along the direction of the conveying path, the three floating knife blocks are opposite to the cutting knife 511 in a vertical direction, and the floating knife blocks can also independently move horizontally along the second direction to avoid the downward movement of the cutting knife 511, in the embodiment, the front floating knife block 521 is driven by a front driving mechanism 524, the rear floating knife block 523 is driven by a rear driving mechanism 525, the cutting knife assembly 51 is connected with a lifting push block 53, the lifting push block 53 is matched with the inclined surface of the middle floating knife block 522 to push the middle floating knife block 522 to move along the second direction close to the conveying path.

[0179] The working mode of the cutting mechanism is as follows:

[0180] If the terminal assembly is not NG, the cutting mechanism does not work;

[0181] If the middle part of the terminal assembly has NG, the cutter assembly 51 is actuated, and the floating cutter block 522 is pushed away by the lifting push block 53, while the cutter 511 is lowered to cut the terminal assembly (terminal material belt);

[0182] If the head part of the terminal assembly has NG, the cutter assembly 51 and a horizontal moving cylinder are actuated, and the floating cutter block 522 and the front floating cutter block 521 are pushed away, while the cutter 511 is lowered to cut the terminal assembly (terminal material belt).

[0183] If the tail part of the terminal assembly has NG, the cutter assembly 51 and a horizontal moving cylinder are actuated, and the floating cutter block 522 and the rear floating cutter block 523 are pushed away, while the cutter 511 is lowered to cut the terminal assembly (terminal material belt).

[0184] The cutting device 5 has the advantages that the cutting mechanism adopts a cutting mode in which the cutter assembly 51 cooperates with the floating cutter block assembly 52, and different positions of the terminal material belt can be cut.

[0185] When the terminal assembly is cut due to NG, the welding device 6 is used to weld the cut terminal assembly segments into one body. The specific description is as follows:

[0186] As shown in Figures 23-25 The welding device 6 includes a horizontal moving driving mechanism 61, a welding lifting driving mechanism 62, and a resistance welding head 63. The horizontal moving driving mechanism 61 can drive the welding lifting driving mechanism 62 to move horizontally along the extension direction of the conveying path, and the welding lifting driving mechanism 62 can drive the resistance welding head 63 to move up and down.

[0187] Preferably, the horizontal moving driving mechanism 61 adopts a combination of a motor and a KK module; the welding lifting driving mechanism 62 adopts a lifting cylinder or a combination of a motor and a lead screw, etc.

[0188] The welding device 6 further includes a material pressing mechanism 64, which is arranged on the welding lifting driving mechanism 62 and specifically includes a material pressing lifting cylinder 643, a material pressing plate 641, and a probe 642. The material pressing lifting cylinder 643 is arranged on the welding lifting driving mechanism 62, the material pressing plate 641 is arranged on the output end of the material pressing lifting cylinder 643, and the probe 642 is arranged at the bottom of the material pressing plate 641. The material pressing plate 641 and the probe 642 are moved along the height direction by the material pressing lifting cylinder 643. The material pressing plate 641 is used to press the terminal assembly, and the probe 642 is used to position the terminal assembly.

[0189] The working method of the welding device 6 is as follows: after the terminal assembly is cut due to NG, the terminal assembly is divided into two sections; then the front section of the terminal assembly is driven by the conveying mechanism 11 to a certain distance and stopped (that is, it stops at the welding position), the rear section of the terminal assembly is driven by the conveying mechanism 11 to move until the cutting surfaces of the front and rear sections of the terminal assembly are in contact; then the pressing mechanism 64 works, the lifting cylinder drives the pressing plate 641 and the probe 642 to move downward to press the terminal assembly, and then the horizontal driving mechanism 61 and the welding lifting driving mechanism 62 drive the resistance welding head 63 to move to weld the two sections of the terminal assembly together.

[0190] The welding device 6 has the following advantages: a) the resistance welding head 63 can be adjusted in horizontal position and vertical position, which can well find the welding position; b) the configuration of the pressing mechanism 64 can effectively improve the welding quality.

[0191] The processing line integrates the following processing procedures: terminal tape feeding, terminal shell feeding, terminal tape conveying, terminal tape and terminal shell pressing to form a semi-finished product, semi-finished product detection and cutting, semi-finished product welding and reconnection to form a finished product, etc. The layout is reasonable and the automation degree is high, thereby improving the production efficiency and processing quality and reducing the production cost.

[0192] The conveying device 1 has a novel and reasonable structure, which can ensure accurate feeding of the terminal tape according to the set working rhythm.

[0193] The pressing procedure is divided into two times: the first time is pre-pressing and the second time is compacting. The reason for dividing the pressing procedure into two times is that the terminal shell may not be aligned when it is initially introduced, and direct compacting may easily cause the terminals on the terminal tape to be tilted and damaged. Therefore, the first pre-pressing is actually a trial pressing for guiding and correcting, and the second pressing is compacting directly because the terminal shell is already in the correct position. By adopting two times of pressing, the stability and accuracy of the pressing of the terminal shell and the terminal tape can be greatly improved, thereby ensuring the quality of the terminal assembly.

[0194] The cutting mechanism adopts a cutting mode in which the cutting knife assembly 51 cooperates with the floating knife block assembly 52, which can realize cutting of different positions of the terminal tape.

[0195] The resistance welding head 63 in the welding device 6 can be adjusted in horizontal position and vertical position, and the pressing mechanism 64 is further configured, which can effectively improve the welding quality.

[0196] As shown in Figure 26 , the conveying mechanism 11 is sequentially provided with three groups, which are respectively a first conveying mechanism, a second conveying mechanism and a third conveying mechanism along the conveying path.

[0197] Condition 1: the welding device 6 and the third conveying mechanism are without material (the first material of the tape, which is just connected).

[0198] To ensure the tape smoothly hung on the third transfer mechanism, the product in the d section and e section are all OK; if not, re-count from the cutting position; design size: b+c>d+e;

[0199] · Case 2: normal production, the first transfer mechanism, the second transfer mechanism, the third transfer mechanism position have tape;

[0200] To ensure the tape to reach the welding device 6 position welding, the product in the d size section need all OK; if not, re-count from the cutting position;

[0201] · Case 3: the end of the tape, the left side of the press device 4 has no material, the right side has material;

[0202] 1) To ensure the end of the tape to reach the welding device 6 position welding, need to leave c+d section material quantity cannot be cut (c+d section material cutting after the second transfer mechanism cannot determine can be cut to the welding position remaining material) ;

[0203] 2) design b+c>c+d (to ensure that the c+d section quantity material can not be cut), the third transfer mechanism pull material, b section material normal pull cutting;

[0204] 3) the end of the tape to the cutter position; the third transfer mechanism reverse rotation, cutting device 5 from the tail end continuous cutting material, NG material is all cut; the third transfer mechanism positive rotation will be cut to the welding device 6 position waiting for welding.
