Description

Technical Field

[0001] This utility model belongs to the field of secondary punching technology, and in particular relates to a secondary punching device for blister trays. Background Technology

[0002] Blister trays are commonly used in the medical, electronics, auto parts, and food industries. They are primarily made of PE (polyethylene), are lightweight, and can be gripped and absorbed using a suction device. Blister trays are manufactured using stamping molds. The initial stamped trays often have rough edges, requiring a secondary stamping process to remove them. Currently, this secondary stamping process typically involves manually placing the blister tray into a specific area of ​​the stamping mold before starting the stamping machine. After stamping, the worker removes the stamped tray and places the next one in. This method requires manual loading and unloading, and the stamping equipment must wait for a new workpiece to be placed before proceeding with the next stamping, resulting in low efficiency.

[0020] Example Reference Figures 1 to 8 This embodiment provides a secondary punching device for a blister tray, specifically including: a support platform 1; a pressing power mechanism 2, located above the support platform 1; an upper mold, located at the bottom of the pressing power mechanism 2, which drives the upper mold to press down; a lower mold, located at the top of the support platform 1, having multiple first vertical holes 401 and multiple second vertical holes 402, and a workpiece limiting plate 403 at the top of the lower mold; a roller assembly 5, slidably disposed within the first vertical holes 401, which transports the workpiece to above the workpiece limiting plate 403; an adsorption assembly 6, slidably disposed within the second vertical holes 402, which adsorbs the workpiece above the workpiece limiting plate 403; a feeding mechanism, located on one side of the support platform 1, which transports the workpiece to the roller assembly 5; and a discharging mechanism, located on the side of the support platform 1 away from the feeding mechanism, which unloads the punched workpiece.

[0021] The upper mold includes a lower pressure plate 301, and a cavity 302 is provided at the bottom of the lower pressure plate 301. Trimming protrusions 303 are provided around the perimeter of the cavity 302.

[0022] The downward pressing mechanism 2 drives the lower pressing plate 301 to move downward, thereby driving the trimming protrusion 303 to punch the workpiece at the top of the workpiece limiting plate 403. The inner and outer sides of the trimming protrusion 303 are smooth surfaces and perpendicular to the horizontal plane, with the inner side serving as the cutting surface.

[0023] The lower mold also includes a connecting plate 404 located at the bottom of the workpiece limiting plate 403. The connecting plate 404 has waste grooves 4041 on all four edges. Multiple waste grooves 4041 are connected end to end to form a closed loop. Multiple wedges 4042 are provided in the waste grooves 4041. The top of the wedges 4042 is provided with a cutting edge for cutting the waste into small segments. The wedges 4042 and the connecting plate 404 are integrally formed.

[0024] The bottom of the connecting plate 404 is provided with a fixing plate 405, which is connected to the top of the support platform 1. The fixing plate 405 has multiple through slots 4051, which are located directly below the waste trough 4041.

[0025] When the upper and lower dies perform the punching action, the large sections of waste material in the waste material groove 4041 are cut into smaller sections by the cutting edges at the top of multiple wedges 4042. The smaller sections of waste material fall down along the waste material groove 4041 into the through groove 4051, and continue to fall down along the through groove 4051 to below the fixing plate 405. A waste material recycling pipe is provided below the fixing plate 405 for recycling waste material.

[0026] The roller assembly 5 includes multiple electric rollers 504 arranged in a matrix. A hollow tube 503 is connected below the electric rollers 504. The hollow tube 503 is slidably connected to the first vertical hole 401. A power control board 502 is connected to the bottom of the hollow tube 503. The power control board 502 is used to control the multiple electric rollers 504 to rotate synchronously. A first lifting cylinder 501 is connected below the power control board 502.

[0027] The adsorption assembly 6 includes multiple suction nozzles 603, which are slidably connected to the second vertical hole 402. A suction control plate 602 is connected to the bottom of the suction nozzle 603, and a second lifting cylinder 601 is connected below the suction control plate 602. Both the power control plate 502 and the suction control plate 602 are located below the fixed plate 405.

[0028] Each electric wheel 504 is connected to an electric wire, which is located inside the hollow tube 503 and connected to the power control board 502. The power control board 502 controls the rotation of the electric wheel 504. The power control board 502, the electric wheel 504, the suction control board 602, and the suction nozzle 603 are common mechanisms in the prior art, and their working principles will not be described in detail here.

[0029] The feeding mechanism includes a first conveyor belt 701, a second conveyor belt 702, and a belt conveyor assembly 703. The first conveyor belt 701 is used to convey stacked workpieces. A gripping assembly 704 is provided between the first conveyor belt 701 and the second conveyor belt 702. The gripping assembly 704 is used to grip the workpieces on the first conveyor belt 701 one by one and transfer them to the second conveyor belt 702.

[0030] The belt conveyor assembly 703 is located between the second conveyor belt 702 and the support platform 1. The belt conveyor assembly 703 is connected to the support platform 1 through a bracket. The upper surface of the belt conveyor assembly 703 is flush with the upper surface of the electric wheel 504.

[0031] The unloading mechanism includes an unloading plate 801, an unloading sensor 802 on the unloading plate 801, and a guide stacking bin 803 below the unloading plate 801.

[0032] The front side of the support platform 1 is a manual observation position. Two safety light curtains are symmetrically arranged on the side of the fixed plate 405 near the manual observation position. The safety light curtains are connected to the mold controller. When the equipment is running, the safety light curtains monitor in real time whether there is any human error in the area. When a human error occurs, the mold controller controls the equipment to stop suddenly to avoid injury to personnel.

[0033] The material feeding sensor 802 is connected to the mold controller. When the mold performs a punching action and the material feeding sensor 802 senses the material feeding, the mold controller can perform the next punching action. Conversely, if the material feeding sensor 802 does not sense the material feeding, the equipment stops running and waits for the worker to check the equipment, resolve the corresponding problem, and then restart the equipment.

[0034] Below the guide stacking bin 803 is a finished product conveyor belt. The workpieces are corrected in position after passing through the guide stacking bin 803, so that each workpiece falls vertically into the designated area of ​​the finished product conveyor belt, thereby achieving stacking.

[0035] When the equipment is working, the first lifting cylinder 501 is activated to drive the electric wheel 504 to rise to a position flush with the upper surface of the belt conveyor assembly 703. Then, the power control board 502 is activated to control the electric wheel 504 to rotate synchronously. The first conveyor belt 701 transports stacked workpieces. The gripping assembly 704 transfers the topmost workpiece to the second conveyor belt 702 in sequence. The workpieces flow into the belt conveyor assembly 703 and then into the roller assembly 5. The roller assembly 5 drives the workpieces to move directly above the workpiece limiting plate 403.

[0036] At this time, the power control board 502 controls the electric wheel 504 to stop rotating, the second lifting cylinder 601 drives the suction nozzle 603 to move upward, and the suction control board 602 is activated to generate negative pressure at the suction nozzle 603 to adsorb the workpiece. Then, the second lifting cylinder 601 drives the suction nozzle 603 to move downward until it contacts the top of the workpiece limiting plate 403. Multiple locking blocks are set at intervals on the top edge of the workpiece limiting plate 403, and the bottom of the workpiece is provided with a locking groove that cooperates with the locking blocks. The suction nozzle 603 continues to drive the workpiece to move downward. Under the action of the locking groove and the locking blocks, the workpiece overcomes the suction force of the suction nozzle 603 and engages with the workpiece limiting plate 403 to achieve positioning.

[0037] After positioning, the suction nozzle 603 stops adsorbing the workpiece, and at the same time, the roller assembly 5 and the adsorption assembly 6 move downward until they leave the punching area between the upper and lower molds. Then, the pressing power mechanism 2 drives the upper mold to move downward to perform the punching action. When the upper and lower molds are completely closed, the inner wall of the scrap groove 4041 acts as another cutting surface and cooperates with the inner side of the trimming protrusion 303 to cut the material. Small pieces of scrap fall down along the scrap groove 4041 and the through groove 4051, while large pieces of scrap remain in the scrap groove 4041. In the next punching action, since the cutting edge at the top of the wedge 4042 is opposite to the bottom of the trimming protrusion 303, the large pieces of scrap are cut into small pieces of scrap, which then fall down along the scrap groove 4041 and the through groove 4051.

[0038] After punching is completed, the upper mold retracts, the roller assembly 5 moves upward and lifts the workpiece away from the workpiece limiting plate 403, the power control board 502 is activated to control the electric wheel 504 to rotate synchronously, driving the workpiece to move to the lower material plate 801, the workpiece falls into the material plate 801 and drops into the guide stacking bin 803, and enters the subsequent flow line.

[0039] The above content is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
