Description

[0002] During the production and processing of resistors, it is necessary to perform laser marking and printing on the surface of the resistor, and its electrical performance also needs to be detected during laser marking and printing. In order to improve the level of mechanical automation of the enterprise, it is necessary to develop a non-standard device for automatically marking and printing resistors and detecting their electrical performance.

[0003] The traditional development thinking mode is a linear assembly line design, where each mechanism is linearly arranged on both sides of the assembly line. The resistor passes through each mechanism in turn under the transmission of the assembly line, and each mechanism performs corresponding operations on it. However, this design idea of the linear assembly line will make the span of the entire device very long, occupying a large amount of indoor space.

[0004] In addition, when detecting the electrical performance of resistors, according to the past experience of the enterprise, the probability of resistors being defective during the electrical performance detection is very low, which belongs to a small-probability event. Even for small-probability events, it is necessary to pick out and eliminate the defective resistors. How to distinguish small-probability defective products from large-probability non-defective products in an economically feasible way and improve production efficiency is a problem that needs to be considered.

The blanking notch 513 is formed between the marking and detecting track 511 and the auxiliary track 512. During the blanking process, the resistor will sink under the guidance of the inclined surface 514 and enter the blanking notch 513, and at the same time, it will be blocked by the blocking surface 515 and will not be out of position.

[0051] Next, the specific structure of the horizontal moving module 400 will be described:

[0052] As shown Figure 6 in the figure, the horizontal moving module 400 includes a horizontal lateral driving part 410 and a horizontal longitudinal driving part 420. The horizontal lateral driving part 410 is used for driving the resistor marking and detecting device 500, the clamping and resistance detecting device 600, and the good product blanking hopper 700 to reciprocate horizontally. The horizontal longitudinal driving part 420 is used for driving the resistor marking and detecting device 500, the clamping and resistance detecting device 600, and the good product blanking hopper 700 to reciprocate vertically.

[0053] Next, the specific structure of the feeding device 100 will be described:

[0054] As shown Figure 7 in the figure, the feeding device 100 includes: a vibrating disk 110 (as shown Figure 2As shown in the figure, a linear vibrator 120 and a feeding track 130 are provided. The feeding track 130 is arranged on the linear vibrator 120, and the discharge port of the vibrating bowl 110 is connected to the marking and inspection track 511 through the feeding track 130.

[0055] As Figure 7 shown, the feeding device 100 further includes a material stopping component 140 arranged on one side of the feeding track 130. The material stopping component 140 includes a material stopping block 141 and a material stopping air cylinder 142 which is drivingly connected to the material stopping block 141; As Figure 7 shown, the feeding device 100 further includes a pressing block 150 arranged above the feeding track 130.

[0056] Next, the specific structure of the good product pushing device 200 will be described:

[0057] As Figure 7 shown, the good product pushing device 200 includes a good product pushing block 210 and a good product pushing air cylinder 220 which is drivingly connected to the good product pushing block 210.

[0058] Next, the specific structure of the mixed material sorting device 300 will be described:

[0059] As Figure 7 shown, the mixed material sorting device 300 includes: a mixed material temporary storage track 310 and a sorting manipulator 320.

[0060] As Figure 8 shown, a linear guiding cavity 311 is formed along the extension direction of the mixed material temporary storage track 310. The guiding cavity 311 communicates with the side wall of the mixed material temporary storage track 310 to form a linear through groove 312.

[0061] As Figure 8 shown, the sorting manipulator 320 includes: a moving rotary head 321 accommodated in the guiding cavity 311, and a driver 322 for driving the moving rotary head 321 to reciprocate and rotate forward and backward.

[0062] Next, the working principle of the above-structured resistance surface laser marking and printing device 10 will be described:

[0063] Place the resistor 50 to be marked and inspected in the vibrating bowl 110. The resistor 50 exits from the discharge port of the vibrating bowl 110 and enters the feeding track 130. Under the action of the linear vibrator 120, the resistor 50 enters the marking and inspection track 511;

[0064] When a certain number of resistors 50 are gathered in the marking and inspection track 511, the material stopping air cylinder 142 drives the material stopping block 141 to block the resistor 50 in the feeding track 130 from continuing to enter the marking and inspection track 511;

[0065] When the clamping resistance measuring device 600 operates, the jaw driving part 630 drives the left jaw 610 and the right jaw 620 to approach each other, so that the left clamping block 612 and the right clamping block 622 clamp the resistor 50 on the marking detection track 511, and at the same time, the left detection needle and the right detection needle 621 are respectively in contact with the left and right pins of the resistor 50 to realize the resistance value detection;

[0066] At the same time, the laser marking printer 20 located above the marking detection track 511 operates to perform laser marking on the resistor 50 on the marking detection track 511;

[0067] After the resistor detection and laser marking are completed, there will be two detection structures for the resistor 50 on the marking detection track 511: most likely all are qualified products, and there is a small probability that there are some defective products mixed in;

[0068] When all the resistors 50 on the marking detection track 511 are qualified products, the moving module 40 drives the broken-bridge carrier track 510 to reach the qualified product pushing device 200. First, the power source 530 drives the multi-functional slider 520 to avoid, so that the blanking notch 513 is opened. Then, the qualified product pushing cylinder 220 drives the qualified product pushing block 210 to push the resistor 50 on the marking detection track 511 out from the blanking notch 513 and drop it into the qualified product blanking hopper 700;

[0069] When there are some defective products mixed in the resistors 50 on the marking detection track 511, the moving module 40 drives the broken-bridge carrier track 510 to reach the mixed material sorting device 300, and the power source 530 drives the multi-functional slider 520 to push the resistor 50 on the marking detection track 511 into the mixed material temporary storage track 310;

[0070] The mixed material sorting device 300 starts to work to sort the resistors in the mixed material temporary storage track 310. It should be noted that after the resistor detection is completed, the detection data has been sent to the control center, and the control center realizes the sorting of the resistors by controlling the mixed material sorting device 300; specifically, the driver 322 drives the moving rotary head 321 to pass through each resistor in the mixed material temporary storage track 310 in turn and stay temporarily. During the stay, the driver 322 drives the moving rotary head 321 to rotate forward or backward by a small angle, so as to rotate and stir the resistors on the mixed material temporary storage track 310, so that the resistors can fall off from the mixed material temporary storage track 310; for example, when the current resistor is a qualified product, the driver 322 drives the moving rotary head 321 to rotate forward, and when the current resistor is a defective product, the driver 322 drives the moving rotary head 321 to rotate backward, so as to realize the sorting of qualified products and defective products;

[0071] During the sorting process of the mixing and sorting device 300, the moving module 40 drives the bridge-type conveying track 510 back to the loading track 130, and repeats the previous actions to mark and detect the next batch of resistors.

[0072] For the resistor surface laser marking and printing device 10 of the present invention, each device is arranged non-linearly on both sides of the production line. It mainly sets a fixed module 30 and a moving module 40. The fixed module 30 includes a loading device 100, a good product pushing device 200, and a mixing and sorting device 300 arranged in sequence from left to right. The moving module 40 reaches the loading device 100, the good product pushing device 200, and the mixing and sorting device 300 in a reciprocating movement manner to realize resistor loading, marking and detection, and sorting and unloading. Compared with the design idea of the traditional linear production line, the equipment of the present invention has a short span and is suitable for use in workshops with limited space.

[0073] It should be particularly noted that when detecting the electrical performance of resistors, according to the past experience of the enterprise, the probability of resistors being defective during the electrical performance detection process is very low, which belongs to a small probability event. However, even for a small probability event, it is necessary to select and remove the defective resistors. When small probability defective products appear, it will not affect the normal unloading of high probability good products, thereby improving production efficiency. This is a technical problem that needs to be considered before the equipment development.

[0074] To solve the above technical problems, the present invention particularly sets a good product unloading area and a defective product sorting and unloading area. The high probability good products will be pushed to the good product unloading hopper 700 under the action of the good product pushing device 200, while the low probability good products are pushed to the mixing and sorting device 300 for sorting. It should be particularly noted that in the present invention, 12 resistors are grouped for loading, marking and detection, and the defective products generated can be mixed in them, which is not conducive to sorting. Therefore, based on production efficiency, the present invention separately sets a mixing and sorting device 300. When there are defective products in this group of resistors, the mixing and sorting device 300 sorts this group of resistors to classify and organize the good products and defective products. In this way, although the mixing and sorting device 300 takes a certain amount of time during the sorting process, it does not affect the normal production of high probability good products and can greatly improve production efficiency.

[0075] It should be noted that in the mixing and sorting device 300 of the present invention, a linear guiding cavity 311 is provided along the extension direction of the mixing temporary storage track 310. The guiding cavity 311 communicates with the side wall of the mixing temporary storage track 310 to form a linear through groove 312. Twelve resistors in a group can be smoothly pushed onto the mixing temporary storage track 310, and the resistors can be stably pressed on the linear through groove 312 and are not prone to shaking. When sorting is required, sorting is performed by the moving rotary head 321 in the linear guiding cavity 311. The moving rotary head 321 realizes the sorting of the resistors in a way of linear movement plus forward and reverse rotation, so that the resistors can easily rotate and then fall from the mixing temporary storage track 310. For example, defective products can fall onto the platform, while good products fall from the hopper.

[0076] Furthermore, the present invention also discloses a production process for laser marking and printing on the surface of resistors. Based on the above-mentioned laser marking and printing device 10 for the surface of resistors, it includes the following steps:

[0077] Step 1, the feeding device is used to feed the resistors to the broken-bridge type carrier track and is blocked by the multi-functional slider;

[0078] Step 2, the clamping and resistance measuring device clamps the resistors at the broken-bridge type carrier track and conducts resistance value detection at the same time, and the laser marking and printing machine marks the resistors at the broken-bridge type carrier track;

[0079] Step 3, if all the resistors at the broken-bridge type carrier track are good products, the horizontal movement module drives the resistors at the broken-bridge type carrier track to the good product pushing device, and the good product pushing device pushes the resistors at the broken-bridge type carrier track to the good product discharging hopper and is avoided by the multi-functional slider; if there are defective products among the resistors at the broken-bridge type carrier track, the horizontal movement module drives the resistors at the broken-bridge type carrier track to the mixing and sorting device, the multi-functional slider pushes the resistors at the broken-bridge type carrier track to the mixing and sorting device, and the driver drives the moving rotary head to move back and forth and rotate forward and backward to sort the good products and defective products;

[0080] Step 4, the horizontal movement module drives the broken-bridge type carrier track to return to the feeding device again and repeats the operation of Step 1, and so on.

[0081] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
