Description

Technical Field

[0001] This utility model relates to the field of automated production line technology, and specifically to an automatic electronic scale automatic feeding machine. Background Technology

[0002] Many products undergo a weighing process during assembly line production to ensure product quality and production efficiency. In the past, this process was typically carried out manually, but manual weighing has limited accuracy and cannot perform complete inspections, often resulting in random sampling and low efficiency.

[0003] To address the inefficiency of manual inspection, many manufacturers have adopted the method of directly deploying electronic scales on the production line to weigh products. For example, Chinese utility model patent application CN 219495406 U discloses a belt scale, which includes: a weighing frame; support rollers; and an electronic scale. The electronic scale is fixedly mounted between any two adjacent support rollers via a bracket, and a weighing roller is provided on the top of the weighing platform of the electronic scale. The weighing roller and the support rollers are located on the same support surface. The conveyor belt, driven by the drive rollers, realizes the material conveying function. During the conveying process, the support rollers support the conveyor belt. When the material is conveyed above the weighing roller, the weight of the material is transferred to the electronic scale by the weighing roller, thereby the electronic scale senses the weight of the material and realizes the automatic weighing function during the material conveying process.

[0004] However, this existing belt scale uses a drive roller to move the conveyor belt, and the scale weighs the material when it is delivered to the weighing roller. However, after the material is weighed, it cannot distinguish between good and bad products, and it cannot automatically unload bad products. Alternatively, bad products can only be picked up manually, which is very inefficient and prone to missing, affecting subsequent production.

[0005] In view of the above, the inventors propose the following technical solution. Summary of the Invention

[0025] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0026] See Figures 1 to 6 As shown, an automatic electronic scale automatic feeding machine is provided. In Embodiment 1 of this utility model, it includes: a feeding mechanism 2 distributed along the working direction of the conveyor line 1 for automatic feeding; a weighing mechanism 3 disposed at the discharge end of the feeding mechanism 2 for weighing and detecting the product; and a discharging mechanism disposed on the conveyor line 1 for pushing the product out of the conveyor line 1. A defective product discharge area 5 is provided on the conveyor line 1. The weighing mechanism 3 is provided with a first channel 301 leading to the conveyor line 1 and a second channel 302 leading to the defective product discharge area 5. The discharging mechanism includes a first push rod device 41 distributed along the working direction of the conveyor line 1 for pushing the product into the first channel 301 and a second push rod device 42 perpendicular to or intersecting the working direction of the conveyor line 1 for pushing the product into the second channel 302.

[0027] This invention changes the traditional manual handling method by automatically transferring products to the weighing mechanism 3 via the feeding mechanism 2, effectively improving weighing efficiency and accuracy. Furthermore, compared to existing structures, this invention uses two different channels on the weighing mechanism 3 to distinguish between good and defective products. Good products are pushed into the first channel 301 by the first pusher device 41 of the unloading mechanism, while defective products are pushed into the second channel 302 by the second pusher device 42. This effectively achieves automatic sorting and picking, greatly improving work efficiency and virtually eliminating missed products, thus ensuring the production quality of the entire production line. It is suitable for widespread application in various assembly line weighing equipment.

[0028] The feeding mechanism 2 includes a first support leg 21 and a second support leg 22 disposed on the conveyor line 1, a feeding plate 23 disposed between the first support leg 21 and the second support leg 22, a feeding motor 24 mounted on one end of the feeding plate 23, a first rotating shaft 25 and a second rotating shaft 26 respectively disposed at both ends of the feeding plate 23, a conveyor belt 27 passing around the first rotating shaft 25 and the second rotating shaft 26 and covering the outside of the feeding plate 23, a gearbox 28 connecting the feeding motor 24 and the first rotating shaft 25, and a first guide member 291 and a second guide member 292 disposed in the middle of the feeding plate 23 for guiding the product. The first guide member 291 has a first guide portion 2911 protruding in a triangular shape, and the second guide member 292 has a second guide portion 2921 protruding in a triangular shape. Both the first guide portion 2911 and the second guide portion 2921 are located above the conveyor belt 27 to drive the product to the middle part of the conveyor belt 27. Here, the first guide 291 and the second guide 292 are respectively installed on both sides of the feeding plate 23. The first guide 2911 and the second guide 2921 extend from both sides of the conveyor belt 27 toward the middle. When the product moves forward from one end of the conveyor belt 27, the product located at the edge of the conveyor belt 27 will be blocked by the first guide 2911 and the second guide 2921 and moved to the middle position to ensure that it can be accurately dropped onto the weighing data instrument 34 of the weighing mechanism 3 for weighing.

[0029] The weighing mechanism 3 includes a weighing base 31 mounted on the conveyor line 1, a channel seat 32 mounted on the weighing base 31, a weighing device 33 mounted on the channel seat 32 for weighing products, and a weighing data analyzer 34 mounted on the weighing base 31 for analyzing weighing data. The first channel 301 and the second channel 302 are both located on the channel seat 32. Preferably, the weighing device 33 is directly opposite the discharge end of the conveyor belt 27, and is cylindrical in shape and connected to the weighing data analyzer 34 to transmit weighing data to the weighing data analyzer 34 in real time for analysis.

[0030] The first push rod device 41 includes a first push rod seat 411 disposed on the conveyor line 1, a first push rod unit 412 mounted on one end of the first push rod seat 411, a first slide rail 413 disposed on the first push rod seat 411, a first slider 414 slidably disposed on the first slide rail 413, a first support arm 410 mounted on the first slider 414, a first push rod 415 mounted on the first support arm 410, a first synchronous wheel 416 disposed at the output end of the first push rod unit 412, a second synchronous wheel 417 disposed on the first push rod seat 411, a first synchronous belt 418 sleeved on the first synchronous wheel 416 and the second synchronous wheel 417, and a first brush 419 disposed at the end of the first push rod 415, wherein the front end of the first push rod 415 is arc-shaped, and one end of the first support arm 410 is connected to the first synchronous belt 418. Here, when the weighing mechanism 3 tests the product and finds it to be a good product, the first push rod 412 drives the first synchronous wheel 416 and drives the first synchronous belt 418 to rotate. At the same time, the first synchronous belt 418 drives the first support arm 410 and the first slider 414 to move along the first slide rail 413, so as to drive the first brush 419 of the first push rod 415 to move. The first brush 419 sweeps the product into the first channel 301. When the first brush 419 sweeps, it will not scratch the product, and it can also clean the surface of the weighing device 33 at the same time to avoid residues affecting the weighing data.

Here, the working principle of the second push rod device 42 is basically the same as that of the first push rod device 41, and can be implemented with reference to the scheme of the first push rod device 41. It will not be described in detail here.

[0032] A lifting pad mechanism 8 is provided on the conveyor line 1, and both the loading mechanism 2 and the unloading mechanism are mounted on this lifting pad mechanism 8. The lifting pad mechanism 8 includes several shock-absorbing pads 81 mounted on the conveyor line 1, a lifting screw 82 passing through each shock-absorbing pad 81 from bottom to top, a pad 83 mounted on the upper end of the lifting screw 82, and a lifting nut 84 embedded and fixed in the pad 83 and matching each lifting screw 82. Here, the lifting pad mechanism 8 can improve the balance and stability of the pad 83 by adjusting the lifting screw 82 and the lifting nut 84, and can also move, effectively enhancing adaptability.

[0033] The pad 83 is equipped with a display 831 for displaying weighing data. Here, the display 831 can display the data information of the product being inspected in real time, effectively realizing the visualization of weighing data and improving the degree of automation.

[0034] In the second embodiment of this utility model, combined with Figure 7 As shown, the weighing mechanism 3 is surrounded by a third protective cover 300. The third protective cover 300 has a first clearance opening 310 for avoiding the first channel 301, and a second clearance opening 320 for avoiding the second channel 302. The first push rod device 41 is surrounded by a first protective cover 450 to prevent foreign objects from falling in. The second push rod device 42 is surrounded by a second protective cover 460 to prevent foreign objects from falling in. Compared with Embodiment 1, this embodiment differs only in the third protective cover 300, the first protective cover 450, and the second protective cover 460. All other parts are the same and will not be described in detail here.

[0035] In summary, this invention changes the traditional manual handling method by automatically transferring products to the weighing mechanism 3 via the feeding mechanism 2, effectively improving weighing efficiency and accuracy. Furthermore, compared to existing structures, this invention distinguishes between good and defective products by setting two different channels on the weighing mechanism 3. Good products are pushed into the first channel 301 by the first pusher device 41 of the unloading mechanism, while defective products are pushed into the second channel 302 by the second pusher device 42. This effectively achieves automatic sorting and picking, greatly improving work efficiency and virtually eliminating missed products, thus ensuring the production quality of the entire production line. It is suitable for widespread application in various assembly line weighing equipment.
