Detailed Implementation

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the embodiments of this application. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such uses of the terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0026] Example: Figures 1-6 As shown, an automatic cotton stalk gluing mechanism includes a frame 100 and a feeding unit 200, a gluing unit 300, and a gluing extrusion unit 400 mounted on the frame 100. The feeding unit 200 includes a drive unit 210 and a clamping unit 220 mounted on the drive unit 210. The clamping unit 220 is used to fix the product group 600. The drive unit 210 can drive the clamping unit 220 to rotate. The gluing unit 300 includes a glue supply unit 310 and a pressing unit 320. The pressing unit 320 can drive the clamping unit 220 to run and immerse the product group 600 in the glue supply unit 310 to complete the gluing operation of the product group 600. The gluing extrusion unit 400 can act on the product group 600 to squeeze out excess glue from the product group 600.

[0027] During operation, the clamping unit 220 fixes the product group 600, and the driving unit 210 drives the clamping unit 220 to rotate, so that the product group 600 reaches the position of the adhesive unit 300. The adhesive supply unit 310 stores the adhesive, and the pressing unit 320 acts on the clamping unit 220 to immerse the product group 600 in the adhesive supply unit 310. The adhesive is then applied to the preset position of the product group 600. Then, the driving unit 210 drives the clamping unit 220 to rotate again, so that the product group 600 moves to the position of the extrusion unit 400. The extrusion unit 400 clamps the product group 600 and squeezes out the excess adhesive from the product group 600, thereby obtaining a product with an appropriate amount of adhesive. This application utilizes the cooperation between the drive unit 210, clamping unit 220, glue supply unit 310, pressing unit 320, and extrusion unit 400 to complete the automatic gluing and extrusion operations of the product, ensuring that the product has an appropriate amount of glue, thereby improving product quality and production efficiency, stabilizing the production process, reducing the labor intensity and danger of workers, and the gluing mechanism is miniaturized and desktop-mounted, making it easy to integrate with existing flocking equipment and facilitating operation and maintenance by workers.

[0028] like Figure 1 As shown, the drive unit 210 includes a servo motor 211 and a turntable 212 connected to the servo motor 211. The servo motor 211 can drive the turntable 212 to rotate. The servo motor 211 is fixedly mounted on the frame 100, and the clamping unit 220 is mounted on the turntable 212. Compared with the traditional method of transferring jigs using a divider, using the servo motor 211 to drive the turntable 212 to rotate results in higher rotation accuracy, more stable operation, and reduced vibration amplitude of the mechanism.

[0029] like Figure 1 As shown, the turntable 212 includes a disc-shaped structure, and four sets of clamping units 220 are installed around the turntable 212, such as... Figure 2 As shown, the frame 100 is equipped with a loading station 110, an adhesive bonding station 120, an adhesive extrusion and scraping station 130, and a unloading station 140. A servo motor 211 drives a clamping unit 220 to sequentially occupy the loading station 110, adhesive bonding station 120, adhesive extrusion and scraping station 130, and unloading station 140. An adhesive bonding unit 300 is located at the adhesive bonding station 120, and an adhesive extrusion unit 400 is located at the adhesive extrusion and scraping station 130. When the clamping unit 220 is located at the loading station 110, a robot or worker fixes the product group 600 onto the clamping unit 220. The servo motor 211 drives the clamping unit 220 to rotate 90° clockwise. Figure 2The circular arrows indicate the direction in which the product group 600 on the clamping unit 220 reaches the gluing station 120. After the gluing unit 300 completes the gluing operation on the product group 600, the servo motor 211 drives the clamping unit 220 to rotate 90° clockwise, bringing the product group 600 to the extrusion and scraping station 130. After the extrusion unit 400 completes the extrusion operation on the product group 600, the servo motor 211 drives the clamping unit 220 to rotate 90° clockwise, bringing the product group 600 to the unloading station 140. The robot or worker removes the glued product group 600 from the clamping unit 220, thus completing the entire operation. The turntable 212 rotates cyclically to complete the product cycle. This application has four clamping units 220, meaning four product groups 600 can operate simultaneously, improving product production efficiency.

[0030] like Figure 1 and Figure 3 As shown, the clamping unit 220 includes a base 221, a guide post 222, a support rod 223, and a spring 224. The base 221 is mounted on the drive unit 210, i.e., the base 221 is mounted on the turntable 212. The first end of the guide post 222 is fixedly mounted on the base 221, and the support rod 223 is movably mounted on the second end of the guide post 222. The spring 224 is sleeved on the guide post 222 and is used to reset the support rod 223. The base 221 has an L-shaped structure, the guide post 222 is vertically mounted on the base 221, the support rod 223 is mounted on the upper end of the guide post 222, and the two ends of the spring 224 abut against the base 221 and the support rod 223, respectively. When the pressing unit 320 acts on the support rod 223, the support rod 223 moves down along the guide post 222, and the spring 224 is compressed. When the pressing unit 320 leaves the support rod 223, the support rod 223 resets under the action of the spring 224. The gluing action of product group 600 is performed by using the buffer elastic pressure of spring 224 to reduce the impact of high precision caused by fixture errors.

[0031] like Figure 6 As shown, product group 600 includes a flow channel 610 and a cotton rod 620 fixedly connected to the flow channel 610. The flow channel 610 is fixed to the support rod 223 by a spring clip. The spring clip is not shown in the figure. The flow channel 610 is the channel for injection molding of the cotton rod 620. Plastic particles enter the cotton rod mold through the flow channel 610 to form the cotton rod 620. It is also the excess material formed after injection molding. One set of cotton rod molds forms multiple cotton rods 620. When the mechanism operates at four stations, the cotton rods are fixed to the clamping unit 220 at each station by the spring clip for gluing and extrusion. In subsequent processes, the flow channel 610 is removed to form individual cotton rods 620. Using spring clips to fix product group 600 facilitates manual handling and ensures that the products are clamped to ensure product position accuracy. The design of the spring clips has high compatibility with product fixtures, allowing the mechanism to perform gluing processes on a variety of similar products.

[0032] like Figure 1 and Figure 3 As shown, the glue supply unit 310 includes a glue storage tank 311, a pipe 312, and an adhesive trough 314. The glue storage tank 311 and the adhesive trough 314 are fixedly installed on the frame 100. The pipe 312 is connected to the glue storage tank 311, and a solenoid valve 313 is installed on the pipe 312. The adhesive trough 314 is equipped with an overflow pipe. The pipe 312 is used to introduce the glue from the glue storage tank 311 into the adhesive trough 314. The adhesive trough 314 is located below the glue storage tank 311. The cotton rod 620 is immersed in the adhesive trough 314 to complete the adhesive application. The glue in the glue storage tank 311 flows into the adhesive trough 314 by gravity, and the flow rate of the glue is precisely controlled by the solenoid valve to ensure a stable supply of glue. The overflow pipe allows excess glue in the adhesive trough 314 to overflow, ensuring that the glue level remains constant and thus ensuring a uniform adhesive application height for the cotton rod 620.

[0033] like Figure 1 and Figure 3 As shown, the pressing unit 320 includes a first driving cylinder 321 and a pressure plate 322 connected to the first driving cylinder 321. The first driving cylinder 321 is mounted on the frame 100 and can drive the pressure plate 322 to move up and down. The pressure plate 322 is located above the support rod 223, and the adhesive groove 314 is located below the cotton rod 620. The first driving cylinder 321 drives the pressure plate 322 downward, and the pressure plate 322 acts on the support rod 223, causing the support rod 223 to move downward together with the cotton rod 620, and the lower end of the cotton rod 620 is inserted into the adhesive in the adhesive groove 314.

[0034] like Figure 1 and Figure 2 As shown, the extrusion unit 400 includes a second drive cylinder 410 and a clamping plate 420 connected to the second drive cylinder 410. An extrusion block 430 is fixedly installed on the inner side of the clamping plate 420. The second drive cylinder 410 is fixedly installed on the frame 100 and can drive the clamping plate 420 to move horizontally. This causes the extrusion block 430 to squeeze the cotton rod 620, thereby squeezing out excess glue from the cotton rod 620.

[0035] Optionally, two second drive cylinders 410 are mounted on the frame 100, each second drive cylinder 410 is connected to a clamping plate 420, and the two clamping plates 420 are arranged in parallel. Under the drive of the second drive cylinders 410, the extrusion blocks 430 on the two clamping plates 420 can clamp the product assembly 600 to squeeze out and absorb excess glue on the cotton rod 620. Optionally, the material of the extrusion block 430 includes sponge, artificial cotton, rubber, EVA, or inflatable silicone.

[0036] like Figure 1 andFigure 2 As shown, when product group 600 is located at the extrusion and scraping station 130, a clamping plate 420 is provided on each side of product group 600. Under the action of the second drive cylinder 410, the two clamping plates 420 move towards product group 600 until the extrusion block 430 clamps the cotton rod 620 on product group 600. The extrusion block 430 is made of highly absorbent materials, such as sponge, artificial cotton, or inflatable silicone, to have a certain amount of glue storage capacity.

[0037] like Figure 4 As shown, the automatic adhesive applicator for cotton stalks also includes a scraping unit 500. The scraping unit 500 includes a third drive cylinder 510 and a support plate 520 connected to the third drive cylinder 510. The third drive cylinder 510 is fixedly mounted on the frame 100, and a scraping rod 530 is fixedly mounted on the support plate 520. The third drive cylinder 510 can drive the scraping rod 530 to move up and down to scrape the adhesive off the extrusion unit 400. That is, the adhesive absorbed by the extrusion block 430 is scraped off and recycled into a recycling box for reuse. After the extrusion block 430 has processed a certain number of batches of product groups 600, the amount of adhesive absorbed by the extrusion block 430 will approach the maximum absorption capacity. At this point, the scraping unit 500 scrapes the adhesive off the extrusion block 430 once. This certain number can be any set number of times, such as 10, 15, or 20 times. The process of extrusion block 430 processing one batch of product group 600 is described below: First, extrusion block 430 and product group 600 move relative to each other in the horizontal direction until they are squeezed together; second, extrusion block 430 and product group 600 move relative to each other in the vertical direction, causing the surface of extrusion block 430 and product group 600 to slide relative to each other. At this point, extrusion block 430 and product group 600 complete one batch processing. When a certain number of times (10 times) has been completed, after extrusion block 430 and product group 600 have completed the above processing 10 times, the glue scraping unit 500 scrapes off the glue from extrusion block 430 once.

[0038] The glue scraping unit 500 is located at the glue extrusion and scraping station 130 and below the glue extrusion unit 400. After the glue extrusion block 430 processes a certain number of batches of product groups 600, the third drive cylinder 510 drives the glue scraping rod 530 to move upward and scrape off the glue in the glue extrusion block 430 to ensure the glue absorption capacity of the glue extrusion unit 400, thereby ensuring the continuous operation of the glue bonding mechanism.

[0039] The operation process of this application includes the following steps:

[0040] Step 1: The robot or worker fixes the product group 600 onto the clamping unit 220 of the loading station 110 using spring clips;

[0041] Step 2: Servo motor 211 drives clamping unit 220 to rotate 90° clockwise, as shown. Figure 2 The circular arrow in the image indicates that product group 600 reaches adhesive station 120.

[0042] Step 3: The first drive cylinder 321 drives the pressure plate 322 downward. The pressure plate 322 acts on the support rod 223, causing the support rod 223 to move downward together with the cotton rod 620 until the lower end of the cotton rod 620 is inserted into the glue in the adhesive groove 314, thus completing the adhesive application.

[0043] Step 4: The first drive cylinder 321 drives the pressure plate 322 to move upward, the pressure plate 322 moves away from the support rod 223, and the support rod 223 is reset under the action of the spring 224;

[0044] Step 5: Servo motor 211 drives clamping unit 220 to rotate 90° clockwise again, so that product group 600 reaches the glue extrusion and scraping station 130.

[0045] Step 6: Under the action of the second drive cylinder 410, the two clamping plates 420 move toward the product group 600 until the extrusion block 430 clamps the cotton rod 620 on the product group 600 to squeeze out and absorb the excess glue on the cotton rod 620.

[0046] Step 7: Servo motor 211 drives clamping unit 220 to rotate 90° clockwise again, so that product group 600 reaches unloading station 140. The worker removes the glued product group 600 from clamping unit 220, thus completing the entire operation.

[0047] Step 8: After the extrusion block 430 processes a certain number of batches of product groups 600, the third drive cylinder 510 drives the scraper rod 530 to move upward and scrape off the glue in the extrusion block 430 to ensure the glue absorption capacity of the extrusion unit 400. The glue is recycled into the recycling box for reuse.

[0048] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be determined by the appended claims.
