DETAILED DESCRIPTION

[0023] In order to better explain the present invention and facilitate understanding, the technical solutions and effects of the present invention are described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, a square thin-walled energy storage battery shell horizontal extrusion molding production line includes a polishing, saponification and horizontal reverse extrusion molding unit 1, a shaping and trimming and deburring unit 2 and an industrial cleaning and drying unit 3 which are arranged in sequence and connected by a conveying mechanism. The unit process arrangement order is polishing, saponification and horizontal reverse extrusion molding unit 1, shaping and trimming and deburring unit, and industrial cleaning and drying unit 3.

[0025] like Figure 2As shown in the figure, the polishing saponification and horizontal reverse extrusion forming unit 1 is used for the polishing saponification and multi-mode extrusion forming of raw aluminum plates, and includes a vibratory grinding machine 11, a bucket elevator 12, a multi-outlet vibrating disk 13, a horizontal cold extrusion press 14, a flat conveyor 15, an extrusion product shape detection CCD 16, a defective product ejection cylinder 17, a defective product conveyor 18, a controller (not shown in the figure), and a control cabinet (not shown in the figure) electrically connected to the controller. The extrusion product shape detection CCD 16 is a commercially available CCD camera and is electrically connected to the controller. The defective product ejection cylinder 17 is electrically connected to the control cabinet. The extrusion product shape detection CCD 16 and the defective product ejection cylinder 17 are sequentially installed at the conveying end of the flat conveyor 15, and the defective product ejection cylinder 17 is close to one side of the conveying end of the flat conveyor 15. The defective product conveyor 18 is arranged on the other side of the flat conveyor 15 and corresponds to the defective product ejection cylinder 17. The end sieve opening of the vibratory grinding machine 11 is located above the receiving opening of the bucket elevator 12, and the discharging opening of the bucket elevator 12 is located above the receiving opening of the multi-outlet vibrating disk 13. The vibrating disk channel 131 of the multi-outlet vibrating disk 13 is a multi-channel feeding mechanism of the multi-outlet vibrating disk 13, and there are three outlets in this embodiment. The horizontal cold extrusion press 14 includes a forming bottom die 141, a stripping plate 142, and an extrusion ejector rod 143. The shape of the extrusion ejector rod 143 is the same as the shape of the battery case to be formed, and the number of extrusion ejector rods 143 is the same as the number of outlets of the multi-outlet vibrating disk 13. The vibrating disk channel 131 is communicated with the forming bottom die 141, and the forming bottom die 141 is provided with receiving positions equal to the number of outlets of the multi-outlet vibrating disk 13, forming a structure of multi-mode parallel horizontal extrusion forming. Fiber optic sensors are arranged on the receiving positions. The stripping plate 142 is fixed between the forming bottom die 141 and the extrusion ejector rod 143, and through holes with the same shape as the outer shape of the extrusion ejector rod 143 are formed on the stripping plate 142. The flat conveyor 15 is arranged between the forming bottom die 141 and the stripping plate 142.

[0026] The raw material aluminum plates are manually and disorderly fed into the vibratory grinding machine 11. Zinc stearate is put into the vibratory grinding machine 11 for the polishing and saponification processes. After completion, the materials enter the bucket elevator conveyor 12 through the end sieve opening of the vibratory grinding machine 11, and are conveyed by the bucket elevator conveyor 12 into the multi-outlet vibrating disk 13 for orderly discharging. The orderly block materials enter the forming bottom die 141 of the horizontal cold extrusion press 14 through the discharge opening of the vibrating disk channel 131. When the receiving position of the forming bottom die 141 feeds back all the in-position detection signals of the materials through the fiber optic sensor, the extrusion ejector rod 143 of the horizontal cold extrusion press 14 moves to the receiving position of the forming bottom die 141 for the extrusion action. After the extrusion is completed, the extrusion ejector rod 143 moves backward. The formed battery case moves backward with the extrusion ejector rod 143. When it reaches the stripper plate 142, the formed battery case is blocked by the stripper plate 142. The extrusion ejector rod 143 continues to move backward and disengages from the inner cavity of the formed battery case. The formed battery case drops onto the flat conveyor 15 between the forming bottom die 141 and the stripping plate 142. The flat conveyor 15 continues to convey the extruded and formed battery case backward. When the formed battery case reaches below the extrusion product appearance detection CCD 16, the extrusion product appearance detection CCD 16 takes a photo for detection and transmits the captured information to the controller. The controller compares it with the qualified products pre-set in its system. If the comparison result is a defective product, the information is transmitted to the control cabinet, and the control cabinet issues a working instruction to the defective product ejection cylinder 17, and the defective product is ejected onto the defective product conveyor 18 for discharging and waiting for manual processing; if the comparison result is a qualified product, it is released and continues to be conveyed backward by the flat conveyor 15 to the subsequent process.

[0027] The wall thickness of the product formed by the polishing, saponification and horizontal backward extrusion forming unit 1 is ≤ 0.2 mm.

[0028] As Figure 3 shown, the shaping, trimming and deburring unit 2 is used to successively shape, trim and polish the extruded and formed battery case, and includes a 90° battery case flipping conveyor 21, a transverse moving flat conveyor 22, and a two-dimensional pick-and-place manipulator one 23, a mechanical eccentric shaping press 24 and corresponding shaping dies 25, a two-dimensional pick-and-place manipulator two 26, a mechanical eccentric trimming press 27 and corresponding rotary cutting dies 28, a two-dimensional pick-and-place manipulator three 29 and a polishing machine 210 arranged in sequence. The 90° battery case flipping conveyor 21 is arranged on one side of the starting end of the transverse moving flat conveyor 22 and is fixed on the transverse moving flat conveyor 22; the two-dimensional pick-and-place manipulator one 23 is arranged on one side close to the end of the transverse moving flat conveyor 22.

[0029] As Figure 6 shown, the shaping die 25 includes an upper template 251, a lower die 256, a shaping concave die 252 connected to the upper template 251, a knockout plate 253, a guide plate 257, a wedge block 255, and a punch 254 connected to the lower template 256.

[0030] The two-dimensional pick-and-place manipulator 1 23, the two-dimensional material-picking manipulator 2 26, and the two-dimensional material-picking manipulator 3 29 are all commercially available two-dimensional manipulators. The mechanical eccentric shaping press 24 and the mechanical eccentric trimming press 27 are both commercially available eccentric presses.

[0031] The 90° battery case turning conveyor 21 includes a planar conveying mechanism 211, a battery case aggregate bin 212, and a pneumatic 90° turning mechanism 213. The battery case aggregate bin 212 is fixed on the planar conveying mechanism 211, and a photoelectric sensor is arranged inside the battery case aggregate bin 212; the planar conveying mechanism 211 is fixed on the turning plate 2133 of the pneumatic 90° turning mechanism 213, and the inlet of the battery case aggregate bin 212 corresponds to the starting end of the conveying of the transverse planar conveyor 22; the planar conveying mechanism 211 and the transverse planar conveyor 22 are perpendicularly arranged. As Figure 5 shown, the pneumatic 90° turning mechanism 213 includes a support frame 2131 and a cylinder 2132. The fixed end of the cylinder 2132 is rotatably connected to the bottom rotary connection seat on the support frame 2131, and the turning plate 2133 is hinged to the end of the telescopic end of the cylinder 2132 through the top rotary connection seat. The conveying end of the planar conveying mechanism 211 is fixed on the support frame 2131 through a turning shaft. When the cylinder 2132 extends, the planar conveying mechanism 211 is pushed through the turning plate 2133 to rotate around the conveying end of the planar conveying mechanism 211 fixed on the support frame from the vertical direction to the horizontal direction, realizing the 90° turning of the battery case.

[0032] The battery case is conveyed to the battery case aggregate bin 212 of the 90° battery case turning conveyor 21 through the polishing, saponification and horizontal backward extrusion forming unit 1 via the planar conveyor 15. After the photoelectric sensor in the battery case aggregate bin 212 senses that the bin is full, the pneumatic 90° turning mechanism 213 acts to turn the battery case aggregate bin 212 and the planar conveyor 211 by 90°, making the opening side of the battery case face downward. At this time, the conveying directions of the planar conveying mechanism 211 and the transverse planar conveyor 22 are parallel; then the planar conveyor 211 is started, and the battery case in the battery case aggregate bin 212 is conveyed onto the transverse planar conveyor 22 and conveyed to the end by the transverse planar conveyor 22; the two-dimensional manipulator 1 23 picks up the battery case from the transverse planar conveyor 22 and transfers it to the shaping die 25 of the mechanical eccentric shaping press 24, and the mechanical eccentric shaping press 24 starts to work for shaping; after shaping, the two-dimensional manipulator 2 26 picks it up and transfers it to the rotary cutting die 28 of the mechanical eccentric trimming press 27, and the mechanical eccentric trimming press 27 starts to work for trimming; the trimmed battery case is picked up by the two-dimensional manipulator 3 29 and transferred to the conveyor of the polishing machine 210 for polishing operation, and then continues to be transferred backward.

[0033] like Figure 4 As shown, the industrial cleaning and drying unit 3 is used to clean and dry the battery shell, including a commercially available ultrasonic cleaning and drying machine 31, which includes an internal ultrasonic cleaning machine, a cleaning tank, an internal plane conveyor, and a drying machine, and the internal plane conveyor is arranged in the direction of ultrasonic cleaning first and then drying. The battery shell after the polishing operation is transmitted to the internal plane conveyor of the ultrasonic cleaning and drying machine 31 through the self-contained conveyor of the polishing machine 210, and the finished product is transferred out after ultrasonic cleaning and subsequent drying operations.

[0034] The automated conveying of materials on the entire line is composed of a flat conveyor, a battery shell 90° flip conveyor 21, a multi-outlet vibrating plate 13, a bucket slope conveyor 12 and a secondary manipulator.

[0035] The working principle and process of the above-mentioned horizontal extrusion molding production line for square thin-walled energy storage battery shells are as follows:

[0036] Manually throw the raw material aluminum plates into the vibrating grinding machine 11 disorderly. Zinc stearate is put into the vibrating grinding machine 11 for polishing and saponification processes. After completion, the materials enter the bucket elevator 12 through the end sieve opening of the vibrating grinding machine 11 and are conveyed by the bucket elevator 12 to the multi-outlet vibrating disk 13 for orderly discharging. The orderly blocks enter the forming bottom die 141 of the horizontal cold extrusion press 14 through the discharge port of the vibrating disk channel 131. When the receiving position of the forming bottom die 141 feeds back the signal of all materials in place detected by the fiber optic sensor, the extrusion ejector rod 143 of the horizontal cold extrusion press 14 moves to the receiving position of the forming bottom die 141 for extrusion action. After extrusion, the extrusion ejector rod 143 moves backward, and the formed battery case moves backward with the extrusion ejector rod 143. When it reaches the stripper plate 142, the formed battery case is blocked by the stripper plate 142. The extrusion ejector rod 143 continues to move backward to disengage from the inner cavity of the formed battery case, and the formed battery case drops onto the flat conveyor 15 between the forming bottom die 141 and the stripping template 142. The flat conveyor 15 conveys the extruded and formed battery case backward continuously. When the formed battery case reaches below the extrusion product appearance detection CCD 16, the extrusion product appearance detection CCD 16 takes a photo for detection and transmits the captured information to the controller. The controller compares it with the qualified products preset in its system. If the comparison result is a defective product, the information is transmitted to the control cabinet, and the control cabinet issues a working instruction to the defective product ejection cylinder 17, and the defective product is ejected onto the defective product conveyor 18 for discharging and waiting for manual processing; if the comparison result is a qualified product, it is released and continuously conveyed backward by the flat conveyor 15. The battery case is conveyed by the flat conveyor 15 to the battery case aggregate bin 212 of the 90° flipping conveyor 21 through the polishing saponification and horizontal reverse extrusion forming unit 1. When the photoelectric sensor in the battery case aggregate bin 212 senses full, the pneumatic 90° flipping mechanism 213 acts to flip the battery case aggregate bin 212 and the flat conveyor 211 by 90°, making the opening side of the battery case face downward. At this time, the conveying direction of the flat conveying mechanism 211 is parallel to that of the transverse flat conveyor 22; then the flat conveyor 211 starts and conveys the battery cases in the battery case aggregate bin 212 to the transverse flat conveyor 22 and is conveyed to the end by the transverse flat conveyor 22; the first two-dimensional manipulator 23 picks up the battery case from the transverse flat conveyor 22 and transfers it to the shaping die 25 of the mechanical eccentric shaping press 24, and the mechanical eccentric shaping press 24 starts to work for shaping; after shaping, the second two-dimensional manipulator 26 picks it up and transfers it to the rotary cutting die 28 of the mechanical eccentric trimming press 27, and the mechanical eccentric trimming press 27 starts to work for trimming; the trimmed battery case is picked up by the third two-dimensional manipulator 29 and transferred to the conveyor of the polishing machine 210 for polishing operation and then continues to be conveyed backward. The battery case after polishing operation is conveyed to the internal flat conveyor of the ultrasonic cleaning and drying integrated machine 31 by the conveyor of the polishing machine 210, and is transferred out as a finished product after ultrasonic cleaning and subsequent drying operation.The above production process is a necessary production technological process.
