[0022] The accompanying drawings are for illustrative purposes only and are not to be construed as limitations on this patent. To better illustrate this embodiment, some components of the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted from the accompanying drawings. DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Example 1 like Figure 3 As shown, the tearable seat of this embodiment includes a connecting sleeve 702, and wings 701 are respectively provided on both sides of the connecting sleeve 702. A tearable groove 703 is opened in the middle of the connecting sleeve 702, and the two wings 701 are symmetrically arranged on both sides of the tearable groove 703. After use, the tearable seat product needs to be torn along the tearable groove 703. The tearing force needs to reach a certain value (25N in this embodiment). If the force value is too large, it may cause the product to be difficult to tear, affecting normal use. If the force value is too small, it may cause the product to be accidentally disconnected. Therefore, during the production process, the product is currently regularly inspected (in this embodiment, a batch is inspected every 15 minutes) to ensure product quality.

[0025] like Figure 1 and Figure 4 As shown, an automatic detection device for a tearable seat in this embodiment includes a vibration dividing device 20 for storing the tearable seat 70 and leading the tearable seat 70 out in a fixed posture. A visual screening device 30, a clamping device 40 and a product collecting device 60 are sequentially arranged on the path of the vibration dividing device 20 leading out the tearable seat 70. The automatic detection device also includes a tearing force detection device 50 for detecting the tearable seat clamped by the clamping device 40.

[0026] The tearable seat products guided out along the vibrating material distribution device 20 are first subjected to a preliminary appearance inspection by the visual screening device 30 (the visual screening device 30 will perform an appearance inspection on each tearable seat product). If unqualified products are found, they will be cleaned up in time (because appearance problems rarely occur, once they are found, the machine needs to be stopped for maintenance); products with no appearance problems continue to move forward along the vibrating material distribution device 20, and the tearable seats are regularly extracted by the clamping device 40 and transferred to the tearing force detection device 50 for detection to ensure that the tearing force of the product is within the required appropriate range. Once unqualified products are found, the machine needs to be stopped for maintenance.

[0027] In this embodiment, the product collecting device 60 is a conveyor belt, which can export qualified tearable seats for packaging. In some embodiments, according to the corresponding production requirements of the workshop, the product collecting device 60 can also be set as a collection basket, collection barrel, etc.

[0028] Above the vibration dividing device 20, an injection mold for processing the tearable seat 70 is also provided. The injection mold consists of a first mold shell 101 and a second mold shell 102. According to the actual situation of the workshop and the discharge situation of the vibration dividing device 20, it can be set to one out of two, one out of four, one out of eight and other forms, and adapted to the speed of the subsequent vibration dividing device 20, visual screening device 30, etc. to meet production needs.

[0029] like Figure 2 As shown, the vibrating material distribution device 20 includes a vibrating plate base 201 for storing the tearable seat and a vibrating plate vibrator 202 for driving the vibration of the vibrating plate base 201. The vibrating plate base 201 is provided with a vibrating plate feed channel 203, a vibrating plate circular vibration 204, and a vibrating plate straight vibration 205 for extracting the tearable seat. The vibrating plate feed channel 203, the vibrating plate circular vibration 204, and the vibrating plate straight vibration 205 are connected in sequence. The tearable seat product processed by the injection mold falls onto the vibrating plate base 201. Under the action of the vibrating plate vibrator 202, it moves upward along the vibrating plate feed channel 203 and enters the vibrating plate circular vibration 204 in a fixed posture, and is finally extracted along the vibrating plate straight vibration 205.

[0030] like Figure 4 As shown, the vibration plate straight vibration 205 includes five straight vibration rods 209, and a straight vibration conveying groove 208 for accommodating the tearable seat 70 is formed between two adjacent straight vibration rods 209 (four are provided in this embodiment), and the vibration plate circular vibration 204 has a circular vibration conveying groove (not shown in the figure) connected one by one with the straight vibration conveying groove 208. The posture of the tearable seat 70 in the figure is its conveying posture. Under the action of the vibration dividing device 20, the tearable seat 70 that does not meet the posture requirement will fall into the vibration plate bottom support 201 when it enters the vibration plate circular vibration 204 along the vibration plate feeding channel 203, and will be conveyed along the vibration plate feeding channel 203 again until the posture requirement is met.

[0031] like Figure 12As shown, a transition channel 212 is provided between the vibration plate feeding channel 203 and the vibration plate circular vibration 204, and a transition slope 213 with a gradually deepening slope (gradually deepening from the vibration plate feeding channel 203 to the vibration plate circular vibration 204, and its end passes through the transition channel 212 and is connected one-to-one with the circular vibration conveying trough) is provided on the transition channel 212. In the process of the tearable seat 70 entering the vibration plate circular vibration 204 along the vibration plate feeding channel 203 and the transition channel 212, other parts of the tearable seat 70 cannot enter the transition slope 213 (as well as the subsequent circular vibration conveying trough and straight vibration conveying trough 208. Due to size issues, the specific size of this equipment is designed according to the size of the tearable seat 70, so that the sizes of other parts of the tearable seat 70 are larger than the width of the transition slope 213 and the subsequent circular vibration conveying trough and straight vibration conveying trough 208). During the conveying process of the vibrating material distributing device 20, the tearable seat that has not been inserted into the transition slope 213 and the circular vibration conveying trough and the straight vibration conveying trough 208 will gradually fall off the vibrating material distributing device 20 under the action of vibration, ensuring that the tearable seat product that maintains the required posture (i.e., the tearable seat that has been inserted into the transition slope 213 and the circular vibration conveying trough and the straight vibration conveying trough 208) can be conveyed forward normally. Figure 4 As shown, the tearable seat product with a fixed posture has one wing 701 extending into the direct vibration conveying groove 208, and the other wing 701 is higher than the upper end surface of the vibration plate 205.

[0032] In other embodiments, the number of straight vibration rods 209 and straight vibration conveying troughs 208 can be actually set according to specific production requirements, and the number of circular vibration conveying troughs and transition slopes 213 can also be changed accordingly.

[0033] A retaining ring 207 is sleeved around the outside of the vibrating plate feed channel 203. A notch 206 is defined at the bottom of the retaining ring 207 to facilitate the entry of the tearable seat 70 into the vibrating plate feed channel 203. A tearable seat that falls from the injection mold may fall into the retaining ring 207 and be directly guided along the vibrating plate feed channel 203. A tearable seat that falls outside the retaining ring 207 may enter the retaining ring 207 through the notch 206 and then be guided along the vibrating plate feed channel 203. The bottom of the vibrating plate base 201 is funnel-shaped, ensuring that a tearable seat that falls outside the retaining ring 207 can smoothly enter through the notch.

[0034] like Figure 5 and Figure 6 As shown, the visual screening device 30 includes a visual screening bracket 301, and the vibration plate 205 passes through the visual screening bracket 301. The visual screening bracket 301 is provided with a sorting light 307 for lighting, a visual screening camera 302 for identifying defective tearable seats, and a sorting part 303 for blowing out the defective tearable seats. The sorting part 303 corresponds one-to-one to the direct vibration conveying trough 208.

[0035] In this embodiment, the sorting unit 303 is a sorting air blowing nozzle. When the tearable seat products are conveyed along the vibrating plate 205, the visual screening camera 302 can automatically identify defective products containing injection defects or black spots under the illumination of the sorting light 307. When a defective product is found, the sorting unit 303 at the corresponding position blows air according to the vibrating conveying trough 208 where the defective product is located, blowing the defective product out of the vibrating plate 205. Qualified products can continue to be conveyed along the vibrating plate 205. In some embodiments, the sorting unit 303 can also be a sorting movable rod / telescopic rod or other device. When a defective product is found, the movable rod extends to remove the defective product from the vibrating plate 205, preventing it from being conveyed further.

[0036] like Figure 7 and Figure 8 As shown, the clamping device 40 includes a clamping bracket 401, on which is provided a vibration plate blocker 410 capable of blocking the transport of the tearable seat and a first clamping jaw 404 for clamping the tearable seat. The clamping bracket 401 is also provided with a first clamping jaw air valve 403 capable of driving the first clamping jaw 404 to move back and forth between the vibration plate direct vibration 205 and the tearing force detection device 50. In this embodiment, a blocker air valve 411 capable of controlling the swing of the vibration plate blocker 410 is provided on the clamping bracket 401. The first clamping jaws 404 are provided at four locations, the same number as the direct vibration conveying slots 208, and the distance between two adjacent first clamping jaws 404 is also consistent with the distance between two adjacent direct vibration conveying slots 208, ensuring that the four first clamping jaws 404 can clamp four tearable seats 70 at the same time. During the transportation of the tearable seat 70 along the vibrating plate 205, the blocker air valve 411 is activated at regular intervals, and the vibrating plate blocker 410 rotates to the left, cutting off the transportation of the tearable seat 70 and positioning the tearable seat 70 at the designated position (the tearable seat 70 moves forward until it contacts the vibrating plate blocker 410 and cannot move forward any further. This position is the designated position); then the first clamping jaw air valve 403 controls the first clamping jaw 404 to move to the clamping position (corresponding to the designated position of the aforementioned tearable seat 70). At this position, the claws of each first clamping jaw 404 are located on both sides of the wing 701 of the corresponding tearable seat 70. Then the claws of the first clamping jaw 404 clamp to clamp four tearable seats 70 and move to the discharge position corresponding to the tearing force detection device 50 under the control of the first clamping jaw air valve 403.

[0037] In this embodiment, the reciprocating movement and clamping and releasing of the first clamping jaw 404 are all controlled by the first clamping jaw air valve 403, which is an existing conventional technology and will not be described in detail in this embodiment.

[0038] The clamping bracket 401 is also provided with a clamping guide rail 402 for reciprocating movement of the first clamping jaw 404, making the movement of the first clamping jaw 404 smoother and more stable. Guide rail buckles 408 for limiting position are provided at both ends of the clamping guide rail 402. In this embodiment, when the first clamping jaw 404 moves to contact the guide rail buckle 408 on the left side, it is in the clamping position, and when it moves to contact the guide rail buckle 408 on the other side, it is in the discharge position.

[0039] like Figure 9 and Figure 10 As shown, the tearing force detection device 50 includes a fixing seat for receiving and fixing the tearable seat 70 delivered by the first clamping jaw 404 and a testing portion for detecting the tearable seat 70 on the fixing seat.

[0040] The fixed base includes a fixed chassis 512, on which a rotating tray 509 is mounted. Six sets of clamping plates 510 are mounted on the rotating tray 509. Each set of clamping plates 510 has two clamping plates 511 for clamping the tearable seat 70. The six sets of clamping plates 510 are evenly spaced on the rotating tray 509. When the tearable seat 70 is not being inspected, one of the clamping plates 510 is located directly below the discharge position of the first clamping jaw 404. To inspect the tearable seat 70, the first clamping jaw 404 moves to the discharge position and places the gripped tearable seat 70 into the clamping plate 510 below it, where the clamping plate 511 clamps the other wing 701. The rotating tray 509 then rotates 60° (this rotation angle needs to be adjusted accordingly depending on the number of clamping plates 510 installed). The next clamping plate 510 rotates below the material discharge position and clamps another tearable plate 70, until the transfer of four tearable plates 70 is completed. The clamping plates 511 are long (the effective clamping length is no less than four times the width of the wings 701 of the tearable plate 70), which can reliably clamp the tearable plates 70 clamped by the four first clamping jaws 404.

[0041] In this embodiment, the effective clamping length of the clamping plate 511 is not less than four times the width of the wing 701 of the tearable seat 70. Its function is: because there are four first clamping jaws 404 and the four first clamping jaws 404 move synchronously, it is necessary to ensure that the clamping plate 511 located at the receiving position can effectively clamp the tearable seat 70 product transported by the first clamping jaw 404, not only the product clamped by the first clamping jaw 404 located at the first position among the four first clamping jaws 404, but also the product clamped by the first clamping jaw 404 located at the last position.

[0042] In other embodiments, if the number of the first clamping jaws 404 is changed, the effective clamping length of the clamping plate 511 must also be changed accordingly. For example, if three first clamping jaws 404 are provided, the effective clamping length of the clamping plate 511 must be no less than three times the width of the wing 701 of the tearable seat 70, thereby achieving reliable clamping of the tearable seat 70.

[0043] An air outlet 513 is provided at the center of the rotating tray 509 to blow out the tearable seat after inspection. After the tearable seat completes the inspection, the corresponding clamping plate 511 is loosened, and the air outlet 513 blows air out to blow it off, making it convenient for the next inspection.

[0044] In order to purify the workshop environment and reduce manual workload, a collection device (such as a collection basket) can be set under the tearing force detection device 50 to collect the tearable seat 70 that has been tested. A dedicated conveyor belt can also be set to transport the tested tearable seat 70 to a designated location. This structure is an existing conventional technology and will not be described in detail in this embodiment.

[0045] like Figure 9 — Figure 11 As shown, the testing part includes a rotating card seat 505, a first connecting arm 506 and a second connecting arm 507 which are hinged in sequence. The rotating card seat 505 is hinged with the connecting seat 501, and the second connecting arm 507 is provided with a second clamping claw 508 for detecting the tearable seat 70.

[0046] In this embodiment, the connecting base 501 and the fixed chassis 512 are both mounted on a tensile testing machine (not shown in the figure). The connecting base 501 is provided with a rotating shaft 502. The rotating clamping base 505 is connected to the second hinge 504, and the middle section of the rotating shaft 502 is located in the arc groove formed by the second hinge 504 and the first hinge 503. The rotating clamping base 505 and the first connecting arm 506, the first connecting arm 506 and the second connecting arm 507 are all connected by a pin, and the second connecting arm 507 and the second clamping jaw 508 are connected by a bolt. After the first clamping jaw 404 transfers the tearable base 70 to the fixed base, the second clamping jaw 508 extends to clamp the wing 701 of the tearable base 70 and moves upward. At this time, the clamping plate 511 clamps the other wing until the tearable base 70 is torn apart (along the tearable groove 703). The tensile testing machine records the tension at this time. In this embodiment, four products are tested each time. If the recorded pulling forces meet the requirements, the products are qualified, the blocker air valve 411 is shut down, the vibration plate blocker 410 rotates to the right, and the vibration plate direct vibration 205 is restored to transport the tearable seat 70. Once it is found that the pulling force does not meet the requirements, the blocker air valve 411 continues to work, the vibration plate blocker 410 continues to block the transportation of the tearable seat 70, and prompts to shut down for maintenance.

[0047] The process of the second clamping jaw 508 clamping the tearable seat 70 is controlled by an air valve and is performed automatically. This is a conventional technology and will not be described in detail in this embodiment.

[0048] When the device is in use, the automatic operation of the equipment is realized through the setting of the injection mold, the vibration distribution device 20, the visual screening device 30, the clamping device 40, the tearing force detection device 50 and the product collection device 60, which greatly improves the production efficiency and also improves the product quality.
