[0058] The present application is described below based on embodiments, but the present application is not limited to these embodiments. In the detailed description of the present application below, some specific details are described in detail. It is possible for those skilled in the art to fully understand the present application without the description of these details. In order to avoid confusing the essence of the present application, known methods, processes, flows, components and circuits are not described in detail.

[0059] In addition, persons of ordinary skill in the art will appreciate that the drawings provided herein are for illustration purposes and are not necessarily drawn to scale.

[0060] Unless otherwise clearly defined and specified, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0062] Unless the context clearly requires otherwise, the words "include", "comprising" and similar words throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, the meaning is "including but not limited to".

[0063] In the description of this application, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0064] Figure 1 It is a structural schematic diagram of a dispensing system provided by an embodiment of the utility model. Figure 2 This is a partial structural diagram of the dispensing system provided by the embodiment of the utility model, combined with Figure 1 and Figure 2 As shown, the dispensing system realizes assembly line operation in the form of an automated machine so as to control and monitor the operation process. Specifically, the dispensing system includes a dispensing device 1, a feeding device 2, a positioning device 3, an operating device 4, a curing device 5, a workbench A, and a carrier B. Among them, the dispensing device 1, the feeding device 2, the positioning device 3, the operating device 4, and the curing device 5 are arranged on the workbench A, and the operating device 4 is configured to operate the carrier B so that multiple carriers B can move synchronously, so that the carrier B can realize the dispensing operation of the product C through recycling.

[0065] Figure 3 Schematic diagram of the structure of the operating device provided by the embodiment of the utility model, such as Figure 3 As shown, in one embodiment, the operating device 4 includes a starting slide 41, a first conveying mechanism 42, a first pushing mechanism 43, a second conveying mechanism 44, a second pushing mechanism 45, a third conveying mechanism 46, a supporting rod 47 and a third pushing mechanism 48. It should be noted that after the operator puts the product C into the carrier B, the carrier B can be slid onto the first conveying mechanism 42 through the starting slide 41. Specifically, Figure 4 : is a schematic diagram of the structure of the starting slide provided by the embodiment of the utility model, such as Figure 4 As shown, the starting slide 41 can be configured as a smooth strip having a plurality of rollers 411 , and the vehicle B can slide via the rollers 411 .

[0066] Figure 5 Schematic diagram of the structure of the first transmission mechanism provided by the embodiment of the utility model. Figure 5 As shown, in one embodiment, the first conveying mechanism 42 includes a first conveying belt 421, a first conveying motor 422, a first conveying sensor 423 and a first ejection cylinder 424. Specifically, the operator pushes the carrier B to the first conveying belt 421 by starting the slide 41, and the first conveying belt 421 drives the carrier B to move toward the positioning device 3 under the drive of the first conveying motor 422. It should be noted that in this embodiment, the carrier B is conveyed by belt transmission, which has the advantages of simple structure, low cost, and convenient installation and maintenance. As an optional embodiment, the carrier B can also be conveyed by chain transmission or other methods. Further, the first conveying belt 421 in this embodiment has two belts arranged at intervals, and the first ejection cylinder 424 can be ejected from between the two belts, so as to temporarily block the carrier B, thereby ensuring that the various operations of the dispensing system can be carried out in an orderly manner. Exemplarily, three first conveying sensors 423 are provided at each position of the first conveying belt 421, and two first ejection cylinders 424 are provided at intervals. When the first transmission sensor 423 senses the arrival of carrier B, the corresponding first ejection cylinder 424 will eject and block carrier B. Correspondingly, when the first ejection cylinder 424 retracts, carrier B can continue to move under the action of the first transmission belt 421. It should be noted that the number and position of the first transmission sensor 423 and the first ejection cylinder 424 can be adjusted as needed. It should be further noted that the first transmission sensor 423 can be set as an infrared sensor or other types of sensors.

[0067] Since the dispensing device 1 needs to keep the carrier B relatively still in order to dispense the product C on the carrier B, the positioning device 3 does not involve a conveying structure such as a conveyor belt. To this end, the first propulsion mechanism 43 is arranged at the junction of the first conveying mechanism 42 and the positioning device 3 to provide a function of pushing the carrier B from the first conveying mechanism 42 to the positioning device 3. Figure 6 : is a schematic diagram of the structure of the first propulsion mechanism provided in an embodiment of the utility model, such as Figure 6 As shown, in one embodiment, the first propulsion mechanism 43 includes a first propulsion slide 431, a regulating motor 432, a lifting cylinder 433, a first lever 434, a sensor plate 435 and a propulsion sensor 436. Specifically, the first lever 434 is connected to the lifting cylinder 433, and the lifting cylinder 433 is connected to the first propulsion slide 431. Optionally, the first propulsion slide 431 is configured as a ball screw structure, so that the lifting cylinder 433 can be driven to move back and forth under the action of the regulating motor 432, that is, the first lever 434 can be driven to move back and forth. Optionally, the regulating motor 432 and the first propulsion slide 431 are connected by a synchronous belt transmission. Further, corresponding to the first propulsion slide 431 being configured as a ball screw structure, the sensor plate 435 is fixedly connected to the ball nut, so as to achieve synchronous movement with the lifting cylinder 433. Furthermore, a propulsion sensor 436 is respectively provided at the position where the first propulsion slide 431 is close to and away from the positioning device 3, so that the control motor 432 and the lifting cylinder 433 can be controlled according to the sensing signals of the propulsion sensor 436 at different positions. Therefore, the first propulsion mechanism 43 provided in this embodiment first drives the lifting cylinder 433 away from the positioning device 3 through the control motor 432 in cooperation with the first propulsion slide 431, at which time the lifting cylinder 433 lifts the first lever 434 to a position higher than the height of the carrier B until the sensor sheet 435 moves to the propulsion sensor 436 away from the positioning device 3; then the lifting cylinder 433 lowers the first lever 434 to a position lower than the height of the carrier B, and the control motor 432 cooperates with the first propulsion slide 431 to drive the lifting cylinder 433 close to the positioning device 3, so that the first lever 434 can push the carrier B onto the positioning device 3, so that the product C on the carrier B can be positioned and glued. Optionally, the first propulsion slide 431 and the regulating motor 432 can be replaced by a three-rod slide cylinder to reduce costs.

[0068] Fig.14 is a schematic diagram of the structure of the positioning device provided by the embodiment of the utility model, Fig.15 is a structural schematic diagram of a positioning device provided by an embodiment of the utility model from another perspective, Fig.16 is a schematic diagram of the working position of the positioning device provided by the embodiment of the utility model, combined with Figures 14 to 16As shown, in one embodiment, the positioning device 3 includes a first rotating seat 31, a bearing platform 32, a second rotating seat 33 and a flip cylinder 34. Specifically, the first rotating seat 31 is fixedly arranged above the workbench A, and the second rotating seat 33 is fixedly arranged below the workbench A. Further, the bottom of the bearing platform 32 is provided with a first support 321 and a second support 322 at intervals. It is easy to understand that the top of the bearing platform 32 is configured to carry the carrier B. That is, when the operating device 4 operates the carrier B containing the product C to the position of the positioning device 3 through the first propulsion mechanism 43, the bearing platform 32 is in a feeding position (that is, maintained in a horizontal state) so as to carry the operated carrier B. Furthermore, the first support 321 is rotatably connected to the first rotating seat 31, the cylinder barrel 341 of the flip cylinder 34 is rotatably connected to the second rotating seat 33, and the piston rod 342 of the flip cylinder 34 is rotatably connected to the second support 322. Optionally, the flip cylinder 34 is a pen-shaped cylinder so that it can rotate to a certain extent during the working process. It should be noted that the positions of the first rotating seat 31, the first support 321, the second support 322 and the second rotating seat 33 can be set as needed, so as to determine the matching mode between the flip cylinder 34 and the supporting platform 32. In this embodiment, when the flip cylinder 34 pushes out the piston rod 342, the supporting platform 32 is in the feeding position (such as Fig.14 and Fig.15 When the turning cylinder 34 retracts the piston rod 342, the carrier 32 is in the working position (as shown); Fig.16 As shown). As an optional embodiment, when the flip cylinder 34 retracts the piston rod 342, the carrier 32 is in the feeding position; when the flip cylinder 34 pushes out the piston rod 342, the carrier 32 is in the working position. It should be further explained that the flip angle of the carrier 32, that is, the angle when the carrier 32 is in the working position can be set as needed, for example, set to 90 degrees or 75 degrees. Thus, the positioning device 3 can put the carrier 32 in the feeding position by flipping the cylinder 34, so that the operating device 4 can operate the carrier B onto the carrier 32. Similarly, the positioning device 3 can also put the carrier 32 in the working position by flipping the cylinder 34, so that the dispensing device 1 can dispense glue to the product C on the carrier B. Optionally, when the propulsion sensor 436 away from the positioning device 3 senses the return of the lifting cylinder 433, the positioning device 3 can control the carrier 32 to flip to the working position.

[0069] Fig.17 Schematic diagram of the structure of the support platform provided by the embodiment of the utility model. Fig.17 As shown, in one embodiment, a first avoidance hole 323 is provided on the supporting platform 32. Figures 14 to 16As shown, the positioning device 3 also includes a first limiting mechanism 35. Specifically, the first limiting mechanism 35 is disposed at the bottom of the carrier 32 and is configured to pass through the carrier 32 through the first avoidance hole 323, thereby limiting the movement of the carrier B along the first direction 3a. It should be noted that the first direction 3a is the direction in which the first propulsion mechanism 43 pushes the carrier B. When the carrier B continues to move along the first direction 3a, it can reach the second conveying mechanism 44. It should be further noted that Fig.12 is a schematic diagram of the structure of the carrier provided by the embodiment of the utility model, such as Fig.12 As shown, a bottom groove B2 is provided at the bottom of the carrier B. When the first limiting mechanism 35 passes through the supporting platform 32 and is pushed out, it can be embedded in the bottom groove B2 to prevent the carrier B from continuing to move.

[0070] Fig.18 : is a schematic diagram of the structure of the first limiting mechanism provided in the embodiment of the utility model, such as Fig.18 As shown, in one embodiment, the first limiting mechanism 35 includes a first limiting cylinder 351 and a first limiting block 352. Specifically, the first limiting cylinder 351 is arranged at the bottom of the carrier 32, and the first limiting block 352 is connected to the piston rod of the first limiting cylinder 351. Thus, the first limiting cylinder 351 can drive the first limiting block 352 through the first avoidance hole 323 and embed into the bottom groove B2 to block the carrier B, or drive the first limiting block 352 to retract and disengage from the bottom groove B2 to achieve release. It is easy to understand that the structure of the first limiting block 352 matches the bottom groove B2. Exemplarily, the bottom groove B2 is a rectangular groove, and the first limiting block 352 is set as a rectangular parallelepiped structure.

[0071] like Fig.17 As shown, in one embodiment, a first protrusion 324 is formed on the top of the carrier 32, and a second avoidance hole 325 is provided on the carrier 32. Furthermore, there is a certain distance between the second avoidance hole 325 and the first protrusion 324. It should be noted that the distance between the second avoidance hole 325 and the first protrusion 324 matches the size of the bottom of the carrier B. Furthermore, in combination with Figures 14 to 16As shown, the positioning device 3 also includes a second limiting mechanism 36. Specifically, the second limiting mechanism 36 is arranged at the bottom of the carrier 32 and passes through the second avoidance hole 325. More specifically, the second limiting mechanism 36 is configured to move in the second avoidance hole 325 along the second direction 3b. It should be noted that the second direction 3b is a horizontal direction perpendicular to the first direction 3a, that is, a direction toward the first protrusion 324. When the carrier B moves to the positioning device 3, that is, moves onto the carrier 32 under the action of the first propulsion mechanism 43, the second limiting mechanism 36 presses the carrier B toward the first protrusion 324, thereby clamping the carrier B between the second limiting mechanism 36 and the first protrusion 324. Therefore, by clamping the carrier B with the first protrusion 324 through the second limiting mechanism 36, the carrier B can be restricted from moving along the second direction 3b to prevent the carrier B from falling. Optionally, a sensor is disposed on the carrying platform 32 , so that the second limiting mechanism 36 can position the carrier B when the sensor detects the carrier B.

[0072] Fig.19 : is a schematic diagram of the structure of the second limiting mechanism provided in the embodiment of the utility model, such as Fig.19 As shown, in one embodiment, the second limiting mechanism 36 includes a second limiting cylinder 361 and a second limiting block 362. Specifically, the second limiting cylinder 361 is arranged at the bottom of the carrier 32, and the second limiting block 362 is connected to the piston rod of the second limiting cylinder 361 and extends out of the second avoidance hole 325. Further, the second limiting cylinder 361 drives the second limiting block 362 to reciprocate along the second direction 3b in the second avoidance hole 325 through the piston rod. Thus, when the carrier B moves onto the carrier 32, the second limiting cylinder 361 drives the second limiting block 362 to move toward the first protrusion 324 to clamp the carrier B, so as to position and dispense the product C on the carrier B; when the product C on the carrier B is dispensed, the second limiting cylinder 361 drives the second limiting block 362 to move away from the first protrusion 324 to release the carrier B, so that the carrier B moves to the second conveying mechanism 44. Optionally, when the positioning device 3 flips the carrying platform 32 to the working position, the second limiting cylinder 361 abuts against the first rotating seat 31 .

[0073] like Fig.17As shown, in one embodiment, two second protrusions 326 are formed on the top of the carrier 32. Specifically, the second protrusions 326 are located on both sides of the second avoidance hole 325, and there is a spacing between the second protrusions 326 and the first protrusions 324. It is easy to understand that when the first propulsion mechanism 43 pushes the carrier B onto the carrier 32, the carrier B slides into the gap formed between the first protrusion 324 and the second protrusion 326, and the first protrusion 324 and the second protrusion 326 play a certain limiting role on the carrier B. Further, the spacing between the first protrusion 324 and the second avoidance hole 325 is smaller than the spacing between the second protrusion 326 and the first protrusion 324. That is to say, when the second limiting cylinder 361 drives the second limiting block 362 to move toward the first protrusion 324, the second limiting block 362 can be closer to the first protrusion 324 relative to the second protrusion 326, so that the carrier B can be clamped with the first protrusion 324.

[0074] like Fig.15 As shown, in one embodiment, the positioning device 3 also includes a plurality of magnets 37. Specifically, the magnet 37 is disposed on the carrier 32 and is configured to adsorb the carrier B. It should be noted that the number and position of the magnet 37 can be set as needed. Optionally, there are six magnets 37, and they are spaced apart on the carrier 32 in a rectangular array. Thus, when the carrier B moves onto the carrier 32 under the action of the first propulsion mechanism 43, the magnet 37 can adsorb the carrier B to limit the movement of the carrier B along the third direction 3c. It should be noted that the third direction 3c is a vertical direction perpendicular to the first direction 3a. In other words, the carrier B can be positioned from three directions by the first limiting mechanism 35, the second limiting mechanism 36 and the magnet 37, thereby preventing the carrier B from falling during the flipping process to ensure the dispensing quality of the product C.

[0075] Combination Fig.15 and Fig.16 As shown, in one embodiment, the positioning device 3 further includes a buffer mechanism 38. Specifically, the buffer mechanism 38 is disposed on a side of the workbench A away from the second support 322. Further, the buffer mechanism 38 is configured to decelerate the carrier 32 to a stop when it rotates to the feeding position. Thus, after the dispensing of the product C is completed, the carrier 32 rotates from the working position to the feeding position, and the buffering effect of the buffer mechanism 38 on the carrier 32 can reduce collision noise, improve safety, and increase the service life of the positioning device 3.

[0076] Fig. 20 Schematic diagram of the structure of the buffer mechanism provided by the embodiment of the utility model. Fig. 20As shown, in one embodiment, the buffer mechanism 38 includes a buffer seat 381 and a buffer 382. Specifically, the buffer seat 381 is arranged at the bottom of the bearing platform 32, and the buffer 382 is arranged on the buffer seat 381. Further, the buffer 382 is configured to slow down the bearing platform 32 to a stop when it rotates to the feeding position. It should be noted that the buffer 382 in this embodiment is a hydraulic buffer. As an optional embodiment, the buffer 382 can also use other types of buffers such as rubber buffers and spring buffers. It should be further explained that the height of the buffer seat 381 needs to match the feeding position of the bearing platform 32, so that the bearing platform 32 can remain horizontal when it abuts against the buffer seat 381, so that the carrier B can be smoothly moved to the bearing platform 32 or smoothly leave the bearing platform 32.

[0077] The positioning device 3 provided in the embodiment of the utility model includes a first rotating seat 31, a bearing platform 32, a second rotating seat 33 and a flip cylinder 34. Among them, the first rotating seat 31 is fixedly arranged above the workbench A, and the second rotating seat 33 is fixedly arranged below the workbench A. The top of the bearing platform 32 carries the carrier B, and the first support 321 and the second support 322 are arranged at intervals at the bottom, and the first support 321 is rotatably connected to the first rotating seat 31. The cylinder barrel 341 of the flip cylinder 34 is rotatably connected to the second rotating seat 33, and the piston rod 342 is rotatably connected to the second support 322. The flip cylinder 34 pushes out or retracts the piston rod 342, so that the bearing platform 32 rotates between the feeding position and the working position, so that the product C in the carrier B can rotate with it. As a result, the positioning device 3 can eliminate the positioning tolerance, and there is no need to worry about the cumulative positioning tolerance of the carrier B. It can not only ensure the normal operation of the carrier B, but also make the product C in the carrier B rotate with it, so as to perform positioning and dispensing operations on the product C to improve the quality of the dispensing operation.

[0078] As described above, when the carrier B carrying the product C moves onto the carrying platform 32 of the positioning device 3, the positioning device 3 turns the carrying platform 32 to the working position, and the glue dispensing device 1 can dispense glue to the turned product C. Fig.21 Schematic diagram of the structure of the dispensing device provided by the embodiment of the utility model, such as Fig.21 As shown, the dispensing device 1 includes a dispensing head mechanism 11, a driving mechanism 12 and a calibration mechanism 13. The driving mechanism 12 and the calibration mechanism 13 are arranged on a workbench A, and the dispensing head mechanism 11 is connected to the driving mechanism 12. Further, the calibration mechanism 13 is provided with a first dispensing position and a second dispensing position, and the driving mechanism 12 is configured to drive the dispensing head mechanism 11 to move to the calibration mechanism 13 to perform a calibration operation on the dispensing head mechanism 11.

[0079] Fig. 22 Schematic diagram of the structure of the dispensing head mechanism provided by the embodiment of the utility model, such as Fig. 22 As shown, in one embodiment, the dispensing head mechanism 11 includes a first support seat 111, an adjustment component 112, a first dispensing head 113 and a second dispensing head 114. Specifically, the first dispensing head 113 is fixedly disposed on the first support seat 111, and the second dispensing head 114 is movably disposed on the first support seat 111 through the adjustment component 112. In other words, the adjustment component 112 is respectively connected to the first support seat 111 and the second dispensing head 114, and the position of the second dispensing head 114 relative to the first support seat 111 can be adjusted. Furthermore, the driving mechanism 12 is connected to the first support seat 111, so that the dispensing head mechanism 11 can be driven to move by driving the first support seat 111. It should be noted that in order to improve the dispensing efficiency, a plurality of products C are loaded on the carrier B and are dispensed through a plurality of dispensing heads. Exemplarily, four products C are mounted on the carrier B and glue is dispensed by two glue dispensing heads (the first glue dispensing head 113 and the second glue dispensing head 114). After the two glue dispensing heads dispense glue to two of the products C, the driving mechanism 12 drives the glue dispensing head mechanism 11 to move, that is, drives the first glue dispensing head 113 and the second glue dispensing head 114 to move, so as to dispense glue to the remaining two products C. It should be further explained that in order to ensure the quality of glue dispensing, the relative position between the first glue dispensing head 113 and the second glue dispensing head 114 needs to be calibrated. To this end, the driving mechanism 12 first drives the glue dispensing head mechanism 11 to move, so that the first glue dispensing head 113 moves to the first calibration position; when the first glue dispensing head 113 is located at the first calibration position, the position of the second glue dispensing head 114 can be adjusted by the adjusting component 112, so that the second glue dispensing head 114 can be moved to the second glue dispensing position, thereby realizing the calibration of the first glue dispensing head 113 and the second glue dispensing head 114. It is easy to understand that the first calibration position and the second calibration position can be set according to the position of the product C on the carrier B.

[0080] That is to say, before calibration, the needle of the first dispensing head 113 and the needle of the second dispensing head 114 are installed; because the two needles may be skewed due to installation during installation, the positions of the two needles need to be calibrated. During calibration, the distance between the needle of the first dispensing head 113 and the needle of the second dispensing head 114 should be consistent with the distance between adjacent products C. At the same time, the calibration mechanism 13 is used to detect the position of the first dispensing head 113 and use it as a reference position (zero position). The calibration mechanism 13 is then used to detect the position of the second dispensing head 114, and the calibration distance of the second dispensing head 114 is calculated based on the distance between adjacent products C, thereby avoiding the size error of the two needles causing the first dispensing head 113 and the second dispensing head 114 to produce position deviation relative to product C during dispensing, thereby improving product yield.

[0081] like Fig. 22As shown, in one embodiment, the adjustment assembly 112 includes a first micrometer 1121, a first sliding block 1122, a second micrometer 1123, and a second sliding block 1124. Specifically, the first micrometer 1121 is fixedly disposed on the first support seat 111, the first sliding block 1122 is slidably disposed on the first micrometer 1121 along the first adjustment direction 112a, the second micrometer 1123 is fixedly connected to the first sliding block 1122, the second sliding block 1124 is slidably disposed on the second micrometer 1123 along the second adjustment direction 112b, and the second dispensing head 114 is fixedly mounted on the second sliding block 1124. Therefore, the operator can accurately drive the first sliding block 1122 to move along the first adjustment direction 112a through the first micrometer 1121, thereby driving the second micrometer 1123 and the second sliding block 1124 to move, and then driving the second dispensing head 114 to move along the first adjustment direction 112a; the operator can accurately drive the second sliding block 1124 to move along the second adjustment direction 112b through the second micrometer 1123, thereby driving the second dispensing head 114 to move along the second adjustment direction 112b. It should be noted that the first adjustment direction 112a is a horizontal direction, which is used to adjust the distance between the second dispensing head 114 and the first dispensing head 113 in the horizontal direction, so as to adjust the horizontal position of the second dispensing head 114 based on the second calibration position when the first dispensing head 113 is located at the first calibration position, thereby ensuring that the distance between the second dispensing head 114 and the first dispensing head 113 in the horizontal direction is equal to the distance between the two products C that are dispensing synchronously in the horizontal direction; the second adjustment direction 112b is a vertical direction, which is used to adjust the height of the second dispensing head 114, so as to adjust the vertical position of the second dispensing head 114 based on the second calibration position when the first dispensing head 113 is located at the first calibration position, thereby ensuring that the height of the second dispensing head 114 is equal to the height of the first dispensing head 113. Therefore, the adjustment component 112 can accurately adjust the second dispensing head to the second calibration position when the first dispensing head 113 is in the first calibration position through the first micrometer 1121 and the second micrometer 1123.

[0082] like Fig. 22As shown, in one embodiment, the adjustment assembly 112 further includes a first locking member 1125 and a second locking member 1126. Specifically, the first locking member 1125 is disposed on the first micrometer 1121, and the second locking member 1126 is disposed on the second micrometer 1123. Further, the first locking member 1125 is configured to abut against the first sliding block 1122 to lock the first sliding block 1122, and the second locking member 1126 is configured to abut against the second sliding block 1124 to lock the second sliding block 1124. Optionally, a threaded structure is provided on the first locking member 1125 and the second locking member 1126, so that locking or loosening can be achieved by means of a knob. Therefore, when the first micrometer 1121 completes the adjustment, the first sliding block 1122 can be locked by the first locking piece 1125 to prevent the second dispensing head 114 from loosening in the first adjustment direction 112a; when the second micrometer 1123 completes the adjustment, the second sliding block 1124 can be locked by the second locking piece 1126 to prevent the second dispensing head 114 from loosening in the second adjustment direction 112b.

[0083] Fig.23 Schematic diagram of the structure of the driving mechanism provided by the embodiment of the utility model. Fig.23 As shown, in one embodiment, the driving mechanism 12 includes a first driving component 121, a second driving component 122 and a third driving component 123. Specifically, the first driving component 121 is connected to the first support seat 111, the second driving component 122 is connected to the first driving component 121, and the third driving component 123 is arranged on the workbench A and connected to the second driving component 122. Further, the first driving component 121 is configured to drive the dispensing head mechanism 11 to move along the first dispensing direction 11a; the second driving component 122 is configured to drive the first driving component 121 to move along the second dispensing direction 11b, thereby driving the dispensing head mechanism 11 to move along the first dispensing direction 11a; the third driving component 123 is configured to drive the second driving component 122 to move along the third dispensing direction 11c, thereby driving the first driving component 121 to move along the third dispensing direction 11c, and then driving the dispensing head mechanism 11 to move along the third dispensing direction 11c. It should be noted that the first dispensing direction 11a is a vertical direction, and the second dispensing direction 11b and the third dispensing direction 11c are two mutually perpendicular horizontal directions. Optionally, the second dispensing direction 11b is the same as the pushing direction of the first propulsion mechanism 43. Thus, the driving mechanism 12 can drive the dispensing head mechanism 11 in three dimensions through the first driving component 121, the second driving component 122 and the third driving component 123, so as to drive the dispensing head mechanism 11 to the calibration position or the dispensing position.

[0084] like Fig.23As shown, in one embodiment, the first driving assembly 121 includes a first driving slide 1211 and a first driving motor 1212, and the first driving slide 1211 is arranged along the first dispensing direction 11a and connected to the first support seat 111. It is easy to understand that the first driving motor 1212 drives the first support seat 111 through the first driving slide 1211, that is, drives the dispensing head mechanism 11 to move along the first dispensing direction 11a. Further, the second driving assembly 122 includes a second driving slide 1221, a second driving motor 1222 and a second support seat 1223, and the second support seat 1223 is connected to the first driving assembly 121, and the second driving slide 1221 is arranged along the second dispensing direction 11b and connected to the second support seat 1223. It is easy to understand that the second drive motor 1222 drives the second support seat 1223 through the second drive slide 1221, that is, drives the first drive component 121 to move along the second dispensing direction 11b, thereby driving the dispensing head mechanism 11 to move along the second dispensing direction 11b. Further, the third drive component 123 includes a third drive slide 1231, a third drive motor 1232 and a third support seat 1233, the third support seat 1233 is connected to the second drive component 122, and the third drive slide 1231 is arranged along the third dispensing direction 11c and connected to the third support seat 1233. It is easy to understand that the third drive motor 1232 drives the third support seat 1233 through the third drive slide 1231, that is, drives the second drive component 122 to move along the third dispensing direction 11c, thereby driving the first drive component 121 to move along the third dispensing direction 11c, and then driving the dispensing head mechanism 11 to move along the third dispensing direction 11c. It should be noted that the first driving assembly 121, the second driving assembly 122 and the third driving assembly 123 are driven by a motor in combination with a slide, which can ensure the accuracy and stability of the driving and help improve the dispensing quality.

[0085] Fig.24 Schematic diagram of the structure of the calibration mechanism provided by the embodiment of the utility model. Fig.24 As shown, in one embodiment, the calibration mechanism 13 includes a calibration seat 131 and a plurality of sensors 132. Specifically, the calibration seat 131 is disposed on the workbench A, and the plurality of sensors 132 are disposed at different positions on the calibration seat 131. It is easy to understand that the provision of the plurality of sensors 132 helps to sense the positions of the first dispensing head 113 and the second dispensing head 114 based on three-dimensional space, so that the position of the second dispensing head 114 can be adjusted according to the sensing result to improve the dispensing quality.

[0086] In this application, the distance between two adjacent products C on carrier B can be set in the system first, that is, Fig.12As shown, it can be understood that the distance (offset) between two adjacent products C in the first loading direction X and the third loading direction Z is 0, the distance in the second loading direction Y is a fixed value, and the distance between two adjacent products C is equal. The first dispensing head 113 is fixed after installation. After calibration, the first dispensing head 113 will move to the top of one of the corresponding products. That is, assuming that the first dispensing head 113 is always in zero position, and then the distance between two adjacent products C in the first loading direction X, the second loading direction Y, and the third loading direction Z is set as the standard, the position of the second dispensing head 114 is adjusted by the sensor 132 to correct the distance between the needle of the first dispensing head 113 and the needle of the second dispensing head 114. In fact, after the dispensing device 1 is installed, the center position of the two dispensing cylinders meets the standard requirements. This is mainly due to the fact that when replacing the dispensing head, the needle of the first dispensing head 113 and / or the needle of the second dispensing head 114 may be deflected before or after installation. When the needle tip of any dispensing head is deflected, the position of the second dispensing head 114 in the first loading direction X, the second loading direction Y, and the third loading direction Z can be fine-tuned so that the distance between the first dispensing head 113 and the second dispensing head 114 in the first loading direction X, the second loading direction Y, and the third loading direction Z meets the standard requirements, thereby making the first dispensing head 113 and the second dispensing head 114 respectively aligned with their corresponding products C to be dispensed, thereby achieving precise dispensing and improving the dispensing quality. That is to say, in the present application, the calibration and adjustment method of the first dispensing head 113 and the second dispensing head 114 is as follows: first, the driving mechanism 12 moves the first dispensing head 113 and the second dispensing head 114 to the calibration mechanism 13. Specifically, the first dispensing head 113 is used as a reference to align the first dispensing head 113 with the first calibration position in the calibration mechanism 13 (the alignment operation can also be detected by the sensor 132 to ensure that the first dispensing head 113 is at the zero position), and then the second dispensing head 114 is detected by other sensors 132 and adjusted. The position of 114 makes the distance between the first dispensing head 113 and the second dispensing head 114 in the first loading direction X, the second loading direction Y, and the third loading direction Z meet the standard requirements. Finally, the driving mechanism 12 moves the first dispensing head 113 and the second dispensing head 114 to be directly above the carrier B. It is indicated that during this movement, the moving distance is still calculated with the first dispensing head 113 as the zero position to ensure that the first dispensing head 113 is aligned with the corresponding product C to be dispensed, and thus the second dispensing head 114 is aligned with the corresponding product C to be dispensed.

[0087] like Fig.21As shown, in one embodiment, the glue dispensing device 1 also includes a glue discharge cylinder 14. It is easy to understand that the glue discharge cylinder 14 is configured as a cylindrical structure with an upper opening. Furthermore, the glue discharge cylinder 14 is disposed on the workbench A to accommodate the colloid discharged regularly by the first glue dispensing head 113 and the second glue dispensing head 114, thereby preventing the needles of the first glue dispensing head 113 and the second glue dispensing head 114 from being clogged by the colloid. It should be noted that, in the present embodiment, the glue dispensing head mechanism 11 is moved to the position of the glue discharge cylinder 14 under the driving action of the driving mechanism 12, thereby realizing the glue discharge operation of the first glue dispensing head 113 and the second glue dispensing head 114.

[0088] like Fig.21 As shown, in one embodiment, the glue dispensing device 1 further includes a glue erasing mechanism 15. Specifically, the glue erasing mechanism 15 is disposed on the workbench A. Further, the glue erasing mechanism 15 is configured to erase the colloid remaining at the needles of the first glue dispensing head 113 and the second glue dispensing head 114, thereby preventing the residual colloid from affecting the glue dispensing quality of the first glue dispensing head 113 and the second glue dispensing head 114 on the product C, and preventing the needles of the first glue dispensing head 113 and the second glue dispensing head 114 from being blocked by the residual colloid.

[0089] Fig.25 Schematic diagram of the structure of the eraser mechanism provided by the embodiment of the utility model. Fig.25 As shown, in one embodiment, the glue erasing mechanism 15 includes a glue erasing seat 151, a first reel 152, a second reel 153, a glue erasing platform 154, a plurality of rollers 155, a dust-free cloth 156, and a rotary motor 157. Specifically, the glue erasing seat 151 is disposed on the workbench A, the first reel 152 and the second reel 153 are rotatably disposed on the glue erasing seat 151, the glue erasing platform 154 is disposed on the glue erasing seat 151 and is located between the first reel 152 and the second reel 153, a plurality of rollers 155 are rotatably disposed on the glue erasing seat 151 and are spaced apart from each other, one end of the dust-free cloth 156 is wound on the first reel 152, the other end of the dust-free cloth 156 is mounted on the glue erasing platform 154 through the roller 155 and connected to the second reel 153, and the rotary motor 157 is disposed on the glue erasing seat 151. Furthermore, the rotary motor 157 is configured to drive the second reel 153 to rotate, so that the dust-free cloth 156 wound on the first reel 152 moves toward the second reel 153. Therefore, after the first dispensing head 113 and the second dispensing head 114 perform the glue wiping operation on the dust-free cloth 156 on the glue wiping table 154, the rotary motor 157 can drive the dust-free cloth 156 on the glue wiping table 154 to replace it with a clean part. It is easy to understand that by providing a plurality of rollers 155 to arrange the moving path of the dust-free cloth 156, it is helpful to make the movement of the dust-free cloth 156 smoother.

[0090] The dispensing device 1 provided by the embodiment of the utility model includes a dispensing head mechanism 11, a driving mechanism 12 and a calibration mechanism 13. Among them, the dispensing head mechanism 11 includes a first support seat 111, an adjustment component 112, a first dispensing head 113 and a second dispensing head 114, the first dispensing head 113 is fixedly arranged on the first support seat 111, the second dispensing head 114 is moved and arranged on the first support seat 111 through the adjustment component 112, the driving mechanism 12 is arranged on the workbench A and connected to the first support seat 111, and the calibration mechanism 13 is arranged on the workbench A and is provided with a first calibration position and a second calibration position. The driving mechanism 12 drives the dispensing head mechanism 11 to move to the calibration mechanism 13, and moves the first dispensing head 113 to the first calibration position, and then moves the second dispensing head 114 to the second calibration position through the adjustment component 112, thereby completing the calibration. Therefore, by adjusting the adjustment component 112 and cooperating with the calibration mechanism 13, the position accuracy of the first dispensing head 113 and the second dispensing head 114 can be guaranteed, thereby ensuring the quality of the dispensing operation.

[0091] After the carrier B has finished dispensing glue on the product C through the dispensing device 1 on the positioning device 3 , the carrier B can be pushed onto the second conveying mechanism 44 through the first pushing mechanism 43 . Figure 7 : is a schematic diagram of the structure of the second transmission mechanism provided by the embodiment of the utility model, such as Figure 7As shown, in one embodiment, the second conveying mechanism 44 includes a second conveying belt 441, a second conveying motor 442, a second conveying sensor 443 and a second ejection cylinder 444. Specifically, the carrier B moves onto the second conveying belt 441, and the second conveying belt 441 drives the carrier B to move away from the positioning device 3 under the drive of the second conveying motor 442. It should be noted that in this embodiment, the carrier B is conveyed by belt transmission, which has the advantages of simple structure, low cost, and convenient installation and maintenance. As an optional embodiment, the carrier B can also be conveyed by chain transmission or other methods. Further, the second conveying belt 441 in this embodiment has two belts arranged at intervals, and the second ejection cylinder 444 can be ejected from between the two belts, so as to temporarily block the carrier B, thereby ensuring that the various operations of the dispensing system can be carried out in an orderly manner. Exemplarily, three second conveying sensors 443 are provided at each position of the second conveying belt 441, and three second ejection cylinders 444 are provided at intervals. When the second conveying sensor 443 senses the arrival of carrier B, the corresponding second ejection cylinder 444 will eject and block carrier B. Correspondingly, when the second ejection cylinder 444 retracts, carrier B can continue to move under the action of the second conveying belt 441. It should be noted that the number and position of the second conveying sensor 443 and the second ejection cylinder 444 can be adjusted as needed. It should be further noted that the second conveying sensor 443 can be set as an infrared sensor or other types of sensors. Thus, when carrier B moves to the curing device 5, the second ejection cylinder 444 can lift up carrier B to perform curing operations on product C that has completed the dispensing operation on carrier B.

[0092] Fig.26 Schematic diagram of the structure of the curing device provided by the embodiment of the utility model, such as Fig.26 As shown, in one embodiment, the curing device 5 includes a lamp holder 51, a curing lamp 52 and a lamp cover 53. Specifically, the lamp holder 51 is arranged on the workbench A, the curing lamp 52 is arranged on the lamp holder 51, and the lamp cover 53 is arranged on the lamp holder 51 and covers the curing lamp 52. It should be noted that the curing lamp 52 is arranged as an ultraviolet lamp to cure the colloid, and the lamp cover 53 is used to prevent the ultraviolet lamp from directly covering the operator.

[0093] When the glued product C is completely cured, the second conveying mechanism 44 conveys the carrier B toward the unloading device 2 to unload the product C. Fig. 27 Schematic diagram of the structure of the feeding device provided by the embodiment of the utility model, such as Fig. 27As shown, in one embodiment, the unloading device 2 includes an unlocking mechanism 21, a clamping mechanism 22 and a transporting mechanism 23. Specifically, the unlocking mechanism 21 is disposed on the workbench A and is configured to push the lock B1 on the carrier B to release the carrier B from locking the product C. Fig.13 is a cross-sectional schematic diagram of a carrier provided by an embodiment of the utility model, such as Fig.13 As shown, the carrier B has a camshaft B3, a movable block B4 and a reset member B5. It should be noted that the lower end of the lock buckle B1 is fixedly connected to the camshaft B3, and the upper end of the lock buckle B1 can drive the camshaft B3 to rotate after being pushed. It is easy to understand that the cross-section of the camshaft B3 is an irregular shape, so that the movable block B4 can be driven to move after the camshaft B3 rotates. In other words, when the upper end of the lock buckle B1 is pushed, the camshaft B3 rotates, so that the movable block B4 releases the lock of the product C by moving. Further, the reset member B5 abuts against the movable block B4 to push the movable block B4 to reset after the external force on the lock buckle B1 is removed, and the camshaft B3 and the lock buckle B1 are reset synchronously. Optionally, the reset member B5 is a spring. Thus, the movable block B4 can be reciprocated by the camshaft B3 in cooperation with the reset member B5, so that the locking and unlocking of the product C can be achieved.

[0094] Fig.28 Schematic diagram of the structure of the unlocking mechanism provided by the embodiment of the utility model. Fig.28 As shown, in one embodiment, the unlocking mechanism 21 includes a first slide cylinder 211 and a plurality of push rods 212. Specifically, the first slide cylinder 211 is disposed on the workbench A, and the push rod 212 is connected to the slider of the first slide cylinder 211. Thus, the push rod 212 can be driven to move by the first slide cylinder 211, thereby pushing the lock B1 on the carrier B to unlock the product C; when the first slide cylinder 211 drives the push rod 212 away from the carrier B, the thrust of the push rod 212 on the lock B1 is removed, so that the various parts of the carrier B are reset under the action of the reset member B5.

[0095] When the unlocking mechanism 21 completes unlocking the product C, the clamping mechanism 22 can clamp the product C. Fig.29 Schematic diagram of the structure of the clamping mechanism provided by the embodiment of the utility model. Fig.29As shown, in one embodiment, the clamping mechanism 22 includes a first connecting seat 221, a clamping assembly 222 and a supporting assembly 223. The clamping assembly 222 and the supporting assembly 223 are arranged on the first connecting seat 221. Specifically, the conveying mechanism 23 is arranged on the workbench A and connected to the first connecting seat 221, and the conveying mechanism 23 is configured to drive the clamping mechanism 22 to move between the clamping position and the unloading position. It is easy to understand that the clamping position is the position where the clamping mechanism 22 can clamp the product C on the carrier B, and the unloading position is the position where the clamping mechanism 22 needs to release the product C. Further, when the clamping mechanism 22 is located at the clamping position, the clamping assembly 222 clamps the first part of the product C, and the supporting assembly 223 is configured to support the second part of the product C, so that all parts of the product C can be separated from the carrier B to improve the unloading efficiency. For example, the product C is a wire product, the clamping assembly 222 clamps the wire end of the wire product, and the supporting assembly 223 supports the main body of the wire product, thereby preventing the wire product from being dragged down and entangled with the running device 4 or other devices. Furthermore, when the clamping mechanism 22 clamping the product C moves to the unloading position under the action of the conveying mechanism 23, the clamping assembly 222 and the supporting assembly 223 are configured to release the product C so that the product C can smoothly reach the predetermined position.

[0096] Fig.30 Schematic diagram of the exploded structure of the clamping assembly provided by the embodiment of the utility model, such as Fig.30As shown, in one embodiment, the clamping assembly 222 includes a first clamping jaw cylinder 2221, a first clamping member 2222 and a second clamping member 2223. Specifically, the first clamping jaw cylinder 2221 is disposed on the first connecting seat 221 and has two first movable claws 22211 that are closed or opened relative to each other, the first clamping member 2222 is connected to one first movable claw 22211, and the second clamping member 2223 is connected to the other first movable claw 22211. In other words, the first clamping jaw cylinder 2221 can drive the first clamping member 2222 and the second clamping member 2223 to move synchronously by driving the two first movable claws 22211 to move. Furthermore, the first clamping member 2222 extends downward to form a plurality of first clamping jaws 22221, and the plurality of first clamping jaws 22221 are spaced apart along the clamping direction. Furthermore, the second clamping member 2223 extends downward to form a plurality of second clamping claws 22231, and the plurality of second clamping claws 22231 are spaced apart along the clamping direction and correspond one to one with the plurality of first clamping claws 22231. It should be noted that the clamping direction is the moving direction of the two first movable claws 22211 of the first clamping claw cylinder 2221, and is associated with the placement position of the product C on the carrier B. Thus, under the driving action of the first clamping claw cylinder 2221, the first clamping member 2222 cooperates with the second clamping member 2223 to clamp the first part of the product C, and can prevent the product C from falling during the handling process. It should be further noted that, in the present embodiment, the first movable claw 22211 is moved by sliding, which helps the first clamping member 2222 and the second clamping member 2223 to complete the clamping action.

[0097] Specifically, the first clamping claw 22221 and the corresponding second clamping claw 22231 are opened or closed relative to each other along the clamping direction, and the first clamping claw 22221 and the corresponding second clamping claw 22231 are staggered; each first clamping claw 22221 extends toward the corresponding second clamping claw 22231 to form a first gripping portion 222211, and each second clamping claw 22231 extends toward the corresponding first clamping claw 22221 to form a second gripping portion 222311, and the first gripping portion 222211 cooperates with the second gripping portion 222311 to form a space for gripping the product C. That is, if Figure 29-Figure 30As shown, when it is necessary to grasp the product C, the first clamping jaw cylinder 2221 drives the two first movable jaws 22211 to move toward each other so that the two are relatively closed, and then the two first movable jaws 22211 respectively drive the first clamping jaw 22221 and the second clamping jaw 22231 to move along the clamping direction, and the first gripping portion 222211 on the first clamping jaw 22221 cooperates with the second gripping portion 222311 on the second clamping jaw 22231 to form a space for grasping the product C, until the first clamping jaw 22221 and the corresponding second clamping jaw 22231 are staggered, and the first clamping jaw 22221 and the second clamping jaw 22231 grasp the corresponding product C. Through the above arrangement, multiple first clamping jaws 22221 and multiple second clamping jaws 22231 can be configured on the first movable jaw 22211, thereby realizing batch grasping of product C and improving production efficiency. Furthermore, when it is necessary to release product C, the first clamping jaw 22221 and the second clamping jaw 22231 move away from each other, and the maximum distance between the two can be set to be smaller than the distance between two adjacent first clamping jaws 22221 or the distance between two adjacent second clamping jaws 22231, thereby further improving the loading and unloading efficiency and production efficiency.

[0098] Preferably, soft material can also be provided on the first gripping portion and the second gripping portion to prevent the first clamping claw 22221 and the second clamping claw 22231 from pinching the product C. The soft material can be selected from a material with low hardness and certain elasticity, and there is no specific restriction on its material.

[0099] Fig.31 Schematic diagram of the exploded structure of the supporting assembly provided by the embodiment of the utility model, such as Fig.31As shown, in one embodiment, the supporting assembly 223 includes a second clamping jaw cylinder 2231, a first supporting member 2232 and a second supporting member 2233. Specifically, the second clamping jaw cylinder 2231 is disposed on the first connecting seat 221 and has two second movable claws 22311 that are closed or opened relative to each other, the first supporting member 2232 is connected to one second movable claw 22311, and the second supporting member 2233 is connected to another second movable claw 22311. In other words, the second clamping jaw cylinder 2231 can drive the first supporting member 2232 and the second supporting member 2233 to move synchronously by driving the two second movable claws 22311 to move. Furthermore, the first supporting member 2232 extends downward to form a plurality of first supporting claws 22321, and the plurality of first supporting claws 22321 are spaced and distributed perpendicular to the clamping direction. Furthermore, the second supporting member 2233 extends downward to form a plurality of second supporting claws 22331, and the plurality of second supporting claws 22331 are spaced apart perpendicular to the clamping direction and correspond one to one with the plurality of first supporting claws 22331. Thus, under the driving action of the second clamping claw cylinder 2231, the first supporting member 2232 cooperates with the second supporting member 2233 to support the second part of the product C, and can prevent the product C from being entangled with the device during the handling process. It should be further explained that, in this embodiment, the second movable claw 22311 is moved by rotating, which helps the first supporting member 2232 and the second supporting member 2223 to support the second part of the product C as much as possible.

[0100] Fig.32 Schematic diagram of the structure of the transport mechanism provided by the embodiment of the utility model. Fig.32As shown, in one embodiment, the conveying mechanism 23 includes a first conveying assembly 231 and a second conveying assembly 232. Specifically, the first conveying assembly 231 is connected to the first connecting seat 221, and the second conveying assembly 232 is arranged on the workbench A and connected to the first conveying assembly 231. Further, the first conveying assembly 231 is configured to drive the clamping mechanism 22 to move along the first conveying direction 23a, and the second conveying assembly 232 is configured to drive the first conveying assembly 231 to move along the second conveying direction 23b. It should be noted that the first conveying direction 23a is a vertical direction, and the second conveying direction 23b is a horizontal direction. Thus, the first conveying assembly 231 cooperates with the second conveying assembly 232 to realize moving the clamping mechanism 22 in a vertical plane so as to complete the unloading operation of the product C. Exemplarily, the first conveying component 231 drives the clamping mechanism 22 to move downward along the first conveying direction 23a to the clamping position, so that the clamping mechanism 22 can clamp product C; when product C is clamped by the clamping mechanism 22, the first conveying component 231 drives the clamping mechanism 22 to move upward along the first conveying direction 23a, and the second conveying component 232 drives the first conveying component 231 along the second conveying direction 23b away from the carrier B; then the first conveying component 231 drives the clamping mechanism 22 to move downward along the first conveying direction 23a to the unloading position, and the clamping mechanism 22 releases product C; finally, the first conveying component 231 cooperates with the second conveying component 232 to make the clamping mechanism 22 return to the clamping position along the original path to complete the next unloading operation.

[0101] like Fig.32 As shown, in one embodiment, the first transport assembly 231 includes a second slide cylinder 2311. Specifically, the slider of the second slide cylinder 2311 is connected to the first connecting seat 221. Further, the second slide cylinder 2311 is configured to drive the clamping mechanism 22 to reciprocate in the vertical direction along the first transport direction 23a.

[0102] like Fig.32 As shown, in one embodiment, the second transport assembly 232 includes a second connection seat 2321, a transport slide 2322, and a transport motor 2323. Specifically, the second connection seat 2321 is connected to the second slide cylinder 2311, and the transport slide 2322 is connected to the second connection seat 2321. Further, the transport motor 2323 drives the second slide cylinder 2311 through the transport slide 2322, that is, drives the clamping mechanism 22 to reciprocate in the horizontal direction along the second transport direction 23b.

[0103] like Fig. 27As shown, in one embodiment, the unloading device 2 further includes a conveying mechanism 24. Specifically, the conveying mechanism 24 is disposed on the workbench A and is located below the unloading position. Thus, when the clamping mechanism 22 is located at the unloading position and releases the product C, the product C can fall onto the conveying mechanism 24. Furthermore, the conveying mechanism 24 is configured to convey the product C so that the product C can continue to move to a predetermined detection position, so that the operator can check the dispensing quality of the product C.

[0104] like Fig. 27 As shown, in one embodiment, the conveying mechanism 24 includes a support frame 241, a conveying belt 242 and a conveying motor 243. Specifically, the support frame 241 is arranged on the workbench A, the conveying belt 242 is arranged on the support frame 241, and the conveying motor 243 is arranged on the workbench A and is configured to drive the conveying belt 242. Thus, the conveying mechanism 24 can convey the product C to a predetermined detection position. It should be noted that the specifications of the conveying belt 242 are set to match the size of the product C.

[0105] The unloading device 2 provided in the embodiment of the utility model includes an unlocking mechanism 21, a clamping mechanism 22 and a conveying mechanism 23. Among them, the unlocking mechanism 21 is arranged on the workbench A and is used to push the lock B1 on the carrier B to release the carrier B from locking the product C. The clamping mechanism 22 includes a first connecting seat 221 and a clamping assembly 222 and a supporting assembly 223 arranged on the first connecting seat 221. The conveying mechanism 23 is arranged on the workbench A and connected to the first connecting seat 221 to drive the clamping mechanism 22 to move between the clamping position and the unloading position. When the clamping mechanism 22 is located at the clamping position, the clamping assembly 222 clamps the first part of the product C, and the supporting assembly 223 supports the second part of the product C. When the clamping mechanism 22 is located at the unloading position, the clamping assembly 222 and the supporting assembly 223 release the product C. In this way, the unloading device 2 can realize automatic unloading, and can ensure that the product C and the carrier B can be completely separated, thereby improving the unloading efficiency.

[0106] It should be noted that when the clamping mechanism 22 clamps the product C, the second ejection cylinder 444 is lifted up according to the sensing signal of the second transmission sensor 443, so that the carrier B remains stationary, so that the clamping mechanism 22 clamps the product C. When the clamping mechanism 22 completes clamping the product C, the second ejection cylinder 444 retracts, so that the carrier B continues to move until the second propulsion mechanism 45 is located. Figure 8 : is a schematic diagram of the structure of the second propulsion mechanism provided in the embodiment of the utility model, such as Figure 8As shown, in one embodiment, the second propulsion mechanism 45 includes a second propulsion slide 451, a propulsion cylinder 452, a second lever 453 and an auxiliary slide rail 454. Optionally, the second propulsion slide 451 is configured as a smooth strip. Further, the second lever 453 is connected to the piston rod of the propulsion cylinder 452, so that it can reciprocate under the action of the propulsion cylinder 452, thereby realizing the movement of the vehicle B along the second propulsion slide 451. Furthermore, corresponding to the propulsion cylinder 452 being a pen-shaped cylinder with a longer piston rod, the auxiliary slide rail 454 can play a supporting and guiding role to ensure the stable operation of the second propulsion mechanism 45.

[0107] It should be noted that the carrier B can be moved to the third conveying mechanism 46 via the second propulsion mechanism 45 . Fig. 9 : is a schematic diagram of the structure of the third transmission mechanism provided by the embodiment of the utility model, such as Fig. 9 As shown, in one embodiment, the third conveying mechanism 46 includes a third conveying belt 461, a third conveying motor 462, a stop cylinder 463, a stopper 464 and a stopper sensor 465. Specifically, the third conveying belt 461 is driven by the third conveying motor 462 to allow the carrier B to continue to move until it moves to the position of the stopper sensor 465. Further, the stopper 464 is connected to the piston rod of the stopper cylinder 463, so that it can reciprocate in the vertical direction under the action of the stopper cylinder 463. Thus, when the stopper sensor 465 senses the carrier B, the stopper cylinder 463 drives the stopper 464 to block the carrier B downward to prevent multiple carriers B from colliding or getting stuck. It is easy to understand that when the stopper cylinder 463 drives the stopper 464 to move upward, the carrier B can continue to move under the action of the third conveying belt 461.

[0108] Fig.10 Schematic diagram of the structure of the support rod provided by the embodiment of the utility model, such as Fig.10 As shown, in one embodiment, the support rod 47 includes a base 471 and a rod 472. Specifically, the base 471 is disposed on the workbench A, and the rod 472 is detachably disposed on the base 471. It is easy to understand that the first conveying mechanism 42, the second conveying mechanism 44, and the third conveying mechanism 46 are each correspondingly configured with a support rod 47 to play a supporting role when the carrier B is running, thereby preventing the carrier B from deflecting and falling. It should be noted that the rod 472 of the corresponding length can be selected according to the size of the first conveying mechanism 42, the second conveying mechanism 44, and the third conveying mechanism 46 to ensure that the support rod 47 can complete the supporting role.

[0109] It should be noted that when the third conveying mechanism 46 moves the carrier B to the third pushing mechanism 48 , the third pushing mechanism 48 moves the carrier B toward the starting slide 41 , that is, toward the position where the product C is loaded. Fig.11 : is a schematic diagram of the structure of the third propulsion mechanism provided in the embodiment of the utility model. Fig.11 As shown, in one embodiment, the third propulsion mechanism 48 includes a third propulsion slide 481, a driving motor 482, a steering cylinder 483, and a third lever 484. Specifically, the third lever 484 is connected to the piston rod of the steering cylinder 483, so that the carrier B can be moved to the third propulsion slide 481 under the action of the steering cylinder 483. Further, the third propulsion slide 481 drives the carrier B to move by belt transmission under the action of the driving motor 482, so that the operator can obtain the carrier B and load the product C.

[0110] The dispensing system provided in the embodiment of the utility model realizes the recycling use of the carrier B and the automatic dispensing of the product C through the mutual cooperation of the dispensing device 1, the feeding device 2, the positioning device 3, the operating device 4 and the curing device 5, and helps to improve the efficiency and quality of the dispensing operation.
