Description

Technical Field

[0001] The utility model relates to the field of die cutting, and particularly to a die cutting machine. Background Art

[0002] Die cutting is a common processing technology, mainly used for cutting materials into specific shapes. Die cutting is a process of stamping and cutting materials through a die, and is widely used in industries such as packaging, printing, electronics, and automobiles. The types of die cutting processes include flat-bed die cutting: suitable for medium and small batch production, rotary die cutting: suitable for high-speed large batch production, and laser die cutting: without a die, suitable for small batch customization.

[0003] In the die cutting production process, it is necessary to detect defective products on the conveyor belt. The current conventional detection method is to install a vision detection device: through this device, the images of the products on the conveyor belt are collected, and the images are transmitted to the processor for comparison and analysis to determine whether the products are qualified. When a defective product is identified, the system will activate the rejection mechanism to remove it from the conveyor belt.

[0004] The rejection scheme adopted by traditional die cutting machines is to open a notch on the conveyor belt and set a pressing head device above the notch. When a defective product passes through the notch position, the pressing head presses down to push it into the notch to complete the rejection. However, this design has obvious defects: in actual production, there are often multiple die-cut products arranged in parallel and conveyed simultaneously on the same conveyor belt. If the existing rejection method is adopted, when there is a single defective product in the same batch of products, the action of the pressing head will push all the products in the whole row into the notch, resulting in the mis-rejection of good products. This not only causes material waste, but also when sorting good products from the rejected pile later, due to the products being stacked on top of each other, it is not only difficult to sort, but also extremely easy to cause product damage. Summary of the Utility Model

[0005] In order to overcome the defect that when there is a single defective product in the same batch of products in the prior art, the action of the pressing head will push all the products in the whole row into the notch, resulting in the mis-rejection of good products, the utility model provides a die cutting machine, including:

[0006] A cutting mechanism, which is provided with a conveyor belt and a vision detection module. The conveyor belt is used for conveying products, and the vision detection module is used for detecting whether the products on the conveyor belt are defective products;

[0007] A rejection mechanism, which is installed on the cutting mechanism and is provided with a driving device and a grasping device. The driving device is connected to the grasping device, and the grasping device is used for rejecting the products on the conveyor belt that are detected as defective products by the vision detection module.

[0008] Optionally, the driving device includes a motor, a driving wheel, and a driven wheel. The driving wheel and the driven wheel are connected by a belt, and the motor is connected to the driving wheel.

[0009] Optionally, the gripping device includes a first adsorption component and a second adsorption component, with the first adsorption component and the second adsorption component respectively connected to a belt.

[0010] Optionally, the first adsorption assembly includes a first vacuum suction head, a first cylinder, and a first movable seat. The first movable seat is connected to a belt, and the first cylinder is mounted on the first movable seat. The first cylinder is connected to the first vacuum suction head via a transmission.

[0011] Optionally, the second adsorption assembly includes a second vacuum suction head, a second cylinder, and a second movable base. The second cylinder and the second vacuum suction head are mounted on the second movable base, and the second cylinder and the second vacuum suction head are connected by a drive.

[0015] Optionally, the cutting mechanism includes a base on which a conveyor belt is mounted.

[0016] Optionally, the cutting mechanism is provided with a fixed frame, and the mounting bracket is installed on the fixed frame.

[0017] The beneficial effects of this utility model are as follows: A rejection mechanism is installed on the cutting mechanism. The product is placed on the conveyor belt, the conveyor belt carries the product, the cutting mechanism performs die cutting, and the vision inspection module performs visual inspection on the conveyor belt to determine whether the product on the conveyor belt is defective. If two products in the same batch on the conveyor belt have been die-cut and the vision inspection module detects that one of the products is defective, the rejection mechanism removes the product from the conveyor belt based on the detection result of the vision inspection module. Specifically, the drive device drives the gripping device to the top of the conveyor belt to grip the defective product of the two products. The drive device then drives the gripping device to carry the defective product away from the conveyor belt, while the good products continue to remain on the conveyor belt and eventually reach the designated location. By removing defective products from multiple products in the same batch through the gripping device, the traditional method of removing good and defective products at the same time is changed, avoiding the disadvantage of good products also being removed. This achieves the goal of removing only defective products from multiple products in the same batch. Attached Figure Description

Detailed Implementation

[0025] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0026] This utility model provides a die-cutting machine, including: a cutting mechanism 1, which is provided with a conveyor belt 101 and a vision inspection module. The conveyor belt 101 is used to transport products 3, and the vision inspection module is used to detect whether the products 3 on the conveyor belt 101 are defective products; and a rejection mechanism 2, which is installed on the cutting mechanism 1, and is provided with a driving device 201 and a gripping device 202. The driving device 201 is connected to the gripping device 202, and the gripping device 202 is used to reject the products 3 on the conveyor belt 101 that are detected as defective products by the vision inspection module.

[0027] The cutting mechanism 1 is used to complete the die-cutting process of product 3, and the rejection mechanism 2 is used to reject defective products 3. In this embodiment, a die-cutting process for two products 3 in the same batch is adopted. The cutting mechanism 1 uses rotary die-cutting, and the product 3 it targets is a packaging bag, such as a dog food packaging bag or a snack packaging bag. The conveyor belt 101 is used to transport product 3, and the vision inspection module is used to detect whether product 3 is defective. The conveyor belt 101 is a common production line conveyor belt 101 on the market. The drive device 201 is used to drive the gripping device 202. The drive device 201 can be an electric push rod, a drive device 201 with a motor 203 and a lead screw, or a drive device 201 with a motor 203 and a belt 219, etc. The gripping device 202 can be a gripping robot, a clamping cylinder, or a vacuum suction head, etc.

[0028] In implementation, a rejection mechanism 2 is installed on the cutting mechanism 1. Products 3 are placed on the conveyor belt 101, which carries the products 3. The cutting mechanism 1 performs die-cutting. A vision inspection module performs visual inspection on the products on the conveyor belt 101 to determine if they are defective. If two products 3 in the same batch are die-cut on the conveyor belt 101 and the vision inspection module detects one of them as defective, the rejection mechanism 2 removes the product 3 from the conveyor belt 101 based on the vision inspection module's detection result. Specifically... The drive unit 201 drives the gripping device 202 above the conveyor belt 101 to grip the defective products from the two products 3. The drive unit 201 then drives the gripping device 202 to remove the defective products from the conveyor belt 101, while the good products remain on the conveyor belt 101 and eventually reach the designated location. By using the gripping device 202 to remove defective products from multiple products 3 in the same batch, the traditional method of removing good and defective products at the same time is changed, avoiding the disadvantage of good products being removed as well. This achieves the removal of only defective products from multiple products 3 in the same batch.

[0029] Furthermore, the visual inspection module includes a CCD camera and a processor. The CCD camera is used to capture the product 3 on the conveyor belt 101 and upload the captured image to the processor. The processor is used to receive the image and send execution instructions. After receiving the image, the processor compares and analyzes the image to determine defective products. When a defective product is determined, an execution instruction is sent to the rejection mechanism 2. The rejection mechanism 2 performs the rejection work according to the execution instruction and rejects the product 3 on the conveyor belt 101. A defective product collection device is set on one side of the die-cutting machine. The drive device 201 first drives the gripping device 202 to pick up the defective product from the conveyor belt 101, and then the drive device 201 drives the gripping device 202 to transfer the defective product to the defective product collection device.

[0030] In some embodiments, the drive device 201 includes a motor 203, a drive wheel 204 and a driven wheel 205. The drive wheel 204 and the driven wheel 205 are connected by a belt 219, and the motor 203 is connected to the drive wheel 204.

[0031] In practice, the driving wheel 204 and the driven wheel 205 are installed at intervals and connected by a belt 219. The motor 203 is connected to the driving wheel 204 for transmission. The motor 203 drives the driving wheel 204 to rotate, and the driving wheel 204 drives the belt 219. The gripping device 202 can be connected to the belt 219. The movement of the belt 219 drives the gripping device 202. A defective product collection device is provided on one side of the die-cutting machine. The belt 219 drives the gripping device 202 to move back and forth between the conveyor belt 101 and the defective product collection device.

[0032] In some cases, the drive unit 201 may also be an electric slide, and the gripping device 202 is connected to the electric slide.

[0033] In some embodiments, the gripping device 202 includes a first adsorption component 206 and a second adsorption component 207, with the first adsorption component 206 and the second adsorption component 207 respectively connected to a belt 219.

[0034] The first adsorption component 206 and the second adsorption component 207 are used to grasp defective products by adsorbing them, and the adsorption method is vacuum adsorption.

[0035] In implementation, the belt 219 in the drive unit 201 always maintains two sections moving in opposite directions. The first adsorption component 206 is connected to one section of the belt 219, and the second adsorption component 207 is installed on the other section. When the motor 203 drives the drive pulley 204, the drive pulley 204 drives the belt 219. When the first adsorption component 206 moves towards the conveyor belt 101, the second adsorption component 207 moves in the opposite direction. After the first adsorption component 206 picks up product 3, the motor 203 reverses and drives the drive pulley 204, and the belt... 219 drives the first adsorption component 206 to move in the direction of the conveyor belt 101, while the second adsorption component 207 moves closer to the conveyor belt 101. The second adsorption component 207 can pick up defective products on the conveyor belt 101. After the second adsorption component 207 picks up the defective products, the motor 203 reverses and moves the second adsorption component 207 away from the conveyor belt 101, while the first adsorption component 206 moves closer to the conveyor belt 101. This cycle repeats to achieve the alternating picking up of defective products by the first adsorption component 206 and the second adsorption component 207, thus achieving efficient removal of defective products.

[0036] In some embodiments, the first adsorption assembly 206 includes a first vacuum suction head 208, a first cylinder 209, and a first movable seat 210. The first movable seat 210 is connected to a belt 219, and the first cylinder 209 is mounted on the first movable seat 210. The first cylinder 209 is connected to the first vacuum suction head 208 in a driving connection.

[0037] In practice, the first movable seat 210 is connected to the belt 219, the first cylinder 209 is mounted on the first movable seat 210, and the first vacuum suction head 208 is connected to the first cylinder 209 via transmission. The belt 219 drives the first movable seat 210 to move, and the first movable seat 210 moves closer to the conveyor belt 101. After reaching above the conveyor belt 101, the first cylinder 209 drives the first vacuum suction head 208 to move downward to pick up defective products. After picking up defective products, the first cylinder 209 drives the first vacuum suction head 208 to move upward. The motor 203 reverses the belt 219 to drive the first movable seat 210 to move away from the conveyor belt 101, thereby realizing the rejection of defective products.

[0038] In some embodiments, the first movable seat 210 is provided with two or more first cylinders 209, each first cylinder 209 is connected to a first vacuum suction head 208, and the first movable seat 210 is also provided with a vacuum generator connected to the vacuum suction head. The number of first cylinders 209 and first vacuum suction heads 208 can be set according to the number of products 3 processed in the same batch on the actual production line. By setting multiple first cylinders 209 and a corresponding number of first vacuum suction heads 208, multiple defective products can be picked up at the same time, thereby improving rejection efficiency.

[0039] In some embodiments, the second adsorption assembly 207 includes a second vacuum suction head 211, a second cylinder 212, and a second movable seat 213. The second cylinder 212 and the second vacuum suction head 211 are mounted on the second movable seat 213, and the second cylinder 212 and the second vacuum suction head 211 are connected in a driving connection.

The belt 219 drives the second movable seat 213 to move, and the second movable seat 213 moves closer to the conveyor belt 101. After reaching above the conveyor belt 101, the second cylinder 212 drives the second vacuum suction head 211 to move downward to pick up defective products. After picking up defective products, the second cylinder 212 drives the second vacuum suction head 211 to move upward. The motor 203 reverses the belt 219 to drive the second movable seat 213 to move away from the conveyor belt 101, thereby realizing the rejection of defective products.

[0041] In some embodiments, the second movable seat 213 is provided with two or more second cylinders 212, such as Figure 3As shown, the second moving base 213 is equipped with four cylinders, and each second cylinder 212 is connected to two second vacuum suction heads 211 (the second vacuum suction heads 211 on the two second cylinders 212 in the figure are not shown). The second moving base 213 is also equipped with a vacuum generator, which is connected to the vacuum suction heads. The number of second cylinders 212 and second vacuum suction heads 211 can be set according to the number of products 3 processed in the same batch on the actual production line. By setting multiple second cylinders 212 and corresponding number of second vacuum suction heads 211, multiple defective products can be picked up at the same time, improving rejection efficiency.

[0048] Specifically, the rejection mechanism 2 includes a mounting frame 218, and a drive unit 201 is mounted on the mounting frame 218. The mounting frame 218 has two guide rails, each with a slider. The two guide rails are located on the sides of the belt 219. A first connecting plate 215 connects to the slider on one of the guide rails and also connects to the belt 219. A second connecting plate 217 connects to the slider on the other guide rail. The length of the first connecting plate 215 is greater than the length of the second connecting plate 217, and the height of the slider connected to the first connecting plate 215 is greater than the height of the slider connected to the second connecting plate 217. Therefore, the positions of the first mounting plate 214 and the second mounting plate 216 are staggered, and they will not affect each other when the first mounting plate 214 and the second mounting plate 216 move.
