DETAILED DESCRIPTION

[0041] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0042] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0043] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0044] One of the preferred embodiments of the present application is as follows: Figures 2 to 22 As shown, an automatic glue dispensing device includes a glue dispensing head 200 and a displacement mechanism 3, a clamping mechanism 4, a feeding mechanism 5 and a baking device 7 installed on a workbench 1. The clamping mechanism 4 can be used to clamp or release the product 100 to be glued. The glue dispensing head 200 is installed on the displacement mechanism 3, so that the glue dispensing head 200 is driven by the displacement mechanism 3 to move above the product 100 clamped by the clamping mechanism 4; then the clamping mechanism 4 can drive the product 100 to rotate intermittently, so that during the process of the product 100 rotating one circle, each perforation 101 of the product 100 can be rotated in turn to the bottom of the glue dispensing head 200 for glue dispensing. The baking device 7 is spaced apart from the clamping mechanism 4, and a plurality of placement cavities 7120 are arranged in the baking device 7, and the placement cavity 7120 can be used to heat and cure the product 100 after glue dispensing. The baking device 7 can be connected to the clamping mechanism 4 by transmission, so that when the clamping mechanism 4 releases the product 100, the baking device 7 can place the next idle placement cavity 7120 directly opposite the clamping mechanism 4. The feeding mechanism 5 is installed between the clamping mechanism 4 and the baking device 7 and is connected to the baking device 7 by transmission; when the product 100 is glued, the baking device 7 can move toward the clamping mechanism 4; and then the feeding mechanism 5 can move the product 100 released by the clamping mechanism 4 to the placement cavity 7120 directly opposite the baking device 7 through transmission cooperation with the baking device 7, and then the glue after glueing the product 100 is heated and cured by the baking device 7.

[0045] It should be known that the entire dispensing process of product 100 is:

[0046] First, the product 100 to be dispensed is transported to the clamping mechanism 4 for clamping manually or by a robot.

[0047] Secondly, the displacement mechanism 3 can drive the dispensing head 200 to move to the position just above the through hole 101 of the corresponding product 100 according to the axial position of the through hole 101 on the side wall of the product 100; this position is the set position to which the displacement mechanism 3 moves.

[0048] Secondly, the clamping mechanism 4 rotates intermittently according to the initial position of the through-hole 101 and the number of the through-holes 101 , and then glue is dispensed to each through-hole 101 of the product 100 through the glue dispensing head 200 .

[0049] Secondly, after the product 100 has completed the dispensing, the baking device 7 can move in the direction of the clamping mechanism 4; during the movement of the baking device 7, the clamping mechanism 4 can loosen the product 100 that has completed the dispensing, and can also drive the placement cavity 7120 of the baking device 7 to move, so that the next idle placement cavity 7120 in the baking device 7 can be directly opposite to the product 100 that has completed the dispensing on the clamping mechanism 4; at the same time, the baking device 7 can also drive the loading mechanism 5 to place the product released by the clamping mechanism 4 in the idle placement cavity 7120 directly opposite the baking device 7 through movement.

[0050] Finally, the baking device 7 is reset, and the clamping mechanism 4 is ready to clamp the next product 100 to be dispensed.

[0051] It can be understood that the clamping and loosening of the clamping mechanism 4 in the above process, as well as the loading process of the product 100 to the baking device 7 can be performed automatically. Compared with the traditional manual method, the efficiency of the dispensing production process of the product 100 can be effectively improved; it meets the company's mass production needs.

[0052] In this embodiment, Figure 2 and Figure 3 As shown, the specific structure of the displacement mechanism 3 is a conventional technology of those skilled in the art, and the common structure is: including a first displacement device 31, a second displacement device 32 and a third displacement device 33; the first displacement device 31 is installed on the workbench, the second displacement device 32 is installed on the first displacement device 31, the third displacement device 33 is installed on the second displacement device 32, and the dispensing head 200 is installed on the third displacement device 33. The third displacement device 33 can drive the dispensing head 200 to move in the vertical z direction; the second displacement device 32 can drive the third displacement device 33 together with the dispensing head 200 to move in the horizontal y direction; the first displacement device 31 can drive the second displacement device 32, the third displacement device 33 and the dispensing head 200 to move in the horizontal x direction. Therefore, through the coordinated movement of the first displacement device 31, the second displacement device 32 and the third displacement device 33, the dispensing head 200 can be driven to move to any spatial position within a certain range, and then the perforations 101 on the products 100 of different models can be dispensed.

[0053] It is understandable that the specific structures of the dispensing head 200, the first displacement device 31, the second displacement device 32 and the third displacement device 33 are well known to those skilled in the art, so they will not be elaborated in detail here. Among them, the common structures of the first displacement device 31, the second displacement device 32 and the third displacement device 33 are a motor screw structure and a cylinder or hydraulic cylinder transmission structure.

[0054] In this embodiment, in order to ensure that the displacement mechanism 3 can drive the dispensing head 200 to move accurately to the top of the through hole 101 of the product 100. Fig.14 As shown, the workbench 1 is equipped with a detection device 900 directly below the product 100, which can be specifically installed on the feeding mechanism 5. The number of the detection device 900 is at least one, preferably two; the two detection devices 900 are symmetrically arranged, and the position of the detection device 900 to the clamping mechanism 4 is a set value, and then when the clamping mechanism 4 clamps the product 100, the detection device 900 can detect the relative distance between the perforation 101 on the product 100 and the detection device 900, and then obtain the spatial position of the perforation 101 in the xyz three-coordinate system, and send the position signal to the displacement mechanism 3, so that the displacement mechanism 3 can drive the dispensing head 200 to move to the set position.

[0055] At the same time, the two detection devices 900 can also detect the initial position of the perforation 101 on the clamped product 100 to be glued, so as to obtain the angle at which the clamping mechanism 4 drives the product 100 to make a single rotation, thereby ensuring that after each rotation of the product 100, there is a perforation 101 located directly below the glue dispensing head 200.

[0056] It is understandable that the specific structure and working principle of the detection device 900 are well-known technologies to those skilled in the art. Common detection devices 900 include visual detection sensors and ultrasonic sensors.

[0057] One of the embodiments of the present application is as follows: Figure 2 and Figure 4As shown, the clamping mechanism 4 includes a rotating device 41 and a clamping assembly 42. The clamping assembly 42 is used to clamp or release the product 100. The clamping assembly 42 is supported and installed on the workbench 1 through the support seat 11, and the clamping assembly 42 and the support seat 11 are matched through the driving structure. The output end of the rotating device 41 is connected to the clamping assembly 42 through the transmission structure; when the rotating device 41 rotates forward, the clamping assembly 42 can clamp the product 100 and rotate forward through the transmission structure; when the rotating device 41 rotates reversely, the clamping assembly 42 can release the clamped product 100 driven by the driving structure. The clamping assembly 42 is driven to clamp, rotate and release the product 100 by different directions of a single rotating device 41, and while realizing automatic dispensing of the product 100, the production cost can be reduced by reducing the driving source.

[0058] It should be known that the specific structure and working principle of the rotating device 41 are well known to those skilled in the art. Common rotating devices 41 include motors, rotating cylinders, rotating hydraulic cylinders, and the like.

[0059] In this embodiment, Figure 4 , Figure 6 , Fig. 9 and Figures 17 to 22 As shown, the clamping assembly 42 includes a rotating sleeve 421, a push rod 422 and a plurality of clamping jaw assemblies 423. The rotating sleeve 421 is rotatably mounted on the support seat 11 through a bearing. The number of support seats 11 is at least one. In order to improve the support stability, two support seats 11 may preferably be used. The push rod 422 is slidably matched with the rotating sleeve 421, and both ends of the push rod 422 extend to the outside of the two ends of the rotating sleeve 421; the first end of the push rod 422 is rotatably mounted with a push block 4223, and the second end of the push rod 422 is matched with one of the support seats 11 through a driving structure. A plurality of clamping jaw assemblies 423 are circumferentially arranged on the side of the first end of the push rod 422, and each clamping jaw assembly 423 is respectively hinged to the push block 4223 and the first end of the rotating sleeve 421. The rotating sleeve 421 and the push rod 422 are both connected to the output end of the rotating device 41 through a transmission structure; when the rotating device 41 rotates forward, the rotating sleeve 421 can drive the clamping jaw assembly 423 and the clamped product 100 to rotate forward, and during this process, the push rod 422 remains stationary through the transmission structure; when the rotating device 41 rotates reversely, the push rod 422 can rotate reversely through the transmission structure, so that the push rod 422 moves axially with the cooperation of the driving structure, and then pushes the top block 4223 to drive the clamping jaw assembly 423 to release the clamped product 100.

[0060] In this embodiment, the transmission structure includes a first transmission structure and a second transmission structure; the first transmission structure is used to transmit and connect the rotating sleeve 421 and the output end of the rotating device 41; one end of the second transmission structure is used to connect the push rod 422, and the other end of the second transmission structure is connected to the output end of the rotating device 41 through a one-way bearing; when the rotating device 41 rotates forward, the first transmission structure drives the rotating sleeve 421 to rotate, and the second transmission structure remains stationary through the one-way bearing; when the rotating device 41 rotates reversely, the second transmission structure drives the push rod 422 to rotate reversely through the one-way bearing.

[0061] Specifically, Figure 4 , Figure 5 , Figure 6 and Fig. 9 As shown, the first transmission structure includes a first transmission wheel 411 and a fourth transmission wheel 4211; the first transmission wheel 411 is installed on the output shaft of the rotating device 41, the fourth transmission wheel 4211 is installed on the rotating sleeve 421, and the first transmission wheel 411 and the fourth transmission wheel 4211 are matched and connected. The second transmission structure includes a second transmission wheel 412 and a fifth transmission wheel 4221; the second transmission wheel 412 is installed on the output shaft of the rotating device 41 through a second one-way bearing 415, the fifth transmission wheel 4221 is splined with the top rod 422, and the second transmission wheel 412 and the fifth transmission wheel 4221 are matched and connected.

[0062] When the rotating device 41 rotates forward, the first transmission wheel 411 cooperates with the fourth transmission wheel 4211 to drive the rotating sleeve 421 to rotate, and then the rotating sleeve 421 can drive the clamping jaw assembly 423 and the clamped product 100 to rotate forward; during this process, the second one-way bearing 412 is in a free state, so that the push rod 422 is in a stationary state (the clamping jaw assembly 423 drives the push block 4223 to rotate relative to the push rod 422).

[0063] When the rotating device 41 rotates in the reverse direction, the second one-way bearing 412 is in an engaged state, and then the second transmission wheel 412 can drive the push rod 422 to rotate in the reverse direction by cooperating with the fifth transmission wheel 4221; during this process, the push rod 422 also moves axially under the drive of the driving structure to drive the push block 4223 to drive the clamping claw assembly 423 to release the clamped product 100.

[0064] It is understandable that when the rotating device 41 rotates in the reverse direction, the cooperation between the first transmission wheel 411 and the fourth transmission wheel 4211 can also drive the rotating sleeve 421 and the clamped product 100 to rotate in the reverse direction synchronously. This rotation process may cause the glue in the perforation 101 to splash. Therefore, the first transmission wheel 411 can be connected to the output shaft of the rotating device 41 through the first one-way bearing 414; then when the rotating device 41 rotates forward, the first one-way bearing 414 is in a bite state; when the rotating device 41 rotates in the reverse direction, the first one-way bearing 414 is in a free state, so that the rotating sleeve 421 and the clamped product 100 remain stationary in the circumferential direction.

[0065] It should be known that there are various ways of matching the first transmission wheel 411 and the fourth transmission wheel 4211 as well as the second transmission wheel 412 and the fifth transmission wheel 4221 , and common ones include gear meshing transmission, belt transmission and chain transmission.

[0066] In order to ensure that the clamping jaw assembly 423 has sufficient clamping force on the product 100, as shown in FIG. Fig. 9 As shown, a second spring 425 is sleeved on the rod section between the first end of the push rod 422 and the first end of the rotating sleeve 421, and the two ends of the second spring 425 are respectively connected to the push block 4223 and the rotating sleeve 421; the second spring 425 is always in a stretched state, so that the push block 4223 always pulls the clamping jaw assembly 423 to close in the direction of clamping the product 100 through the elastic force of the second spring 425, thereby clamping the product 100. And when the clamping jaw assembly 423 rotates forward, it can also prevent the push rod 422 and the push block 4223 from synchronously following due to friction interference.

[0067] In this embodiment, Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, a support block 111 is installed on the support seat 11 near the second end of the top rod 422, and a rotating hole 1110 is provided on the support block 111. The second end of the top rod 422 is rotatably matched with the rotating hole 1110. The driving structure includes a driving groove 1111 and a driving block 4222 that are slidably matched; there are two ways to set the driving groove 1111 and the driving block 4222:

[0068] Method 1: Figures 6 to 8 As shown, the driving groove 1111 is disposed on the side wall of the rotating hole 1110 , and the driving block 4222 is disposed on the side wall of the top rod 422 .

[0069] In a second embodiment, the driving groove 1111 is disposed on a side wall of the top rod 422 , and the driving block 4222 is disposed on a side wall of the rotating hole 1110 .

[0070] Taking the above-mentioned method 1 as an example, the driving groove 1111 is in the shape of a cam groove in the circumferential direction, so that when the push rod 422 rotates, the driving block 4222 slides along the driving groove 1111 to drive the push rod 422 to reciprocate along the axial direction; wherein, the movement of the push rod 422 toward the first end direction drives the clamping jaw assembly 423 to release the product 100, and the movement of the push rod 422 toward the second end direction drives the clamping jaw assembly 423 to clamp the product 100.

[0071] Specifically, initially, Figure 8 As shown in (1), the driving block 4222 on the push rod 422 is located at the first extreme position of the driving groove 1111, and the clamping jaw assembly 423 is in a clamping state.

[0072] When the top rod 422 rotates 180° in the opposite direction, Figure 8 As shown in (2), the driving block 4222 on the top rod 422 slides along the driving groove 1111 to the second extreme position. During this process, the top rod 422 moves toward the first end, thereby driving the top block 4223 to move synchronously. During the movement of the top block 4223, the clamping jaw assembly 423 can be driven to rotate around the hinge position with the rotating sleeve 421 in the direction away from the product 100.

[0073] Then, the push rod 422 continues to rotate 180° in the opposite direction, so that the driving block 4222 on the push rod 422 slides along the driving groove 1111 to the first limit position again. Figure 8 The position shown in (1) is used to allow the clamping jaw assembly 423 to clamp the next product 100 to be dispensed.

[0074] In this embodiment, Fig. 9 As shown, one end of the clamping jaw assembly 423 can be hinged to the bracket on the side of the top block 4223, and the other end can be hinged to the bracket on the first end side of the rotating sleeve 421 through the hinge plate 424. Then, when the top block 4223 moves axially under the drive of the top rod 422, the clamping jaw assembly 423 can be driven to rotate around the bracket on the first end side of the rotating sleeve 421 through the hinge plate 424, thereby achieving the clamping or loosening of the product 100.

[0075] It is understandable that the other side of the end of the clamping jaw assembly 423 can be directly hinged to the bracket on the first end side of the rotating sleeve 421; this will cause the bracket on the first end side of the rotating sleeve 421 to be longer and inconvenient to process. Therefore, it is preferred to use a hinge plate 424 for transition connection.

[0076] In this embodiment, Fig. 9As shown, the clamping jaw assembly 423 includes a claw plate 4231 and a clamping plate 4232. The claw plate 4231 is hinged to the top block 4223 and the first end of the rotating sleeve 421 respectively; the clamping plate 4232 is elastically connected to the claw plate 4231. When clamping the product 100, the claw plate 4231 can drive the clamping plate 4232 to clamp the product 100; through the elastic sliding of the clamping plate 4232 relative to the claw plate 4231, products 100 of different diameters can be clamped.

[0077] It should be known that the number of the clamping jaw assemblies 423 is at least two, and the specific number can be selected by those skilled in the art according to actual needs; for example Figure 6 As shown, the number of the clamping jaw assemblies 423 is preferably four.

[0078] Specifically, Fig. 9 As shown, the clamping plate 4232 is slidably matched with the claw plate 4231, and the clamping plate 4232 is located on the side of the claw plate 4231 close to the product 100. At least one first sliding rod 4235 is provided on the clamping plate 4232, and at least one first mounting groove 4233 is provided on the claw plate 4231. The clamping plate 4232 is slidably matched with the first mounting groove 4233 through the first sliding rod 4235. At the same time, a first spring 4234 is installed in the first mounting groove 4233, and the two ends of the first spring 4234 are respectively against the first mounting groove 4233 and the first sliding rod 4235, so that the clamping plate 4232 compresses the first spring 4234 through the first sliding rod 4235, and then the product 100 is clamped by the elastic force of the first spring 4234; by the different compression amounts of the first spring 4234, products 100 with different diameters can be clamped.

[0079] One of the embodiments of the present application is as follows: Figure 2 and Fig.11 As shown, the baking device 7 includes a baking box 71 and a telescopic device 72. A plurality of first guide rails 12 are installed on the workbench 1, and the baking box 71 is slidably matched with the first guide rails 12. The side wall of the baking box 71 is provided with an open groove 7110 facing the placement cavity 7120; the telescopic device 72 is installed on the workbench 1 and connected to the baking box 71 through the output end, so that the baking box 71 can be driven by the telescopic device 72 to move toward the direction of the clamping mechanism 4, so that the feeding mechanism 5 can drive the baking box 71 to pass the dispensing product 100 through the open groove 7110 to place it in the facing placement cavity 7120.

[0080] It is understandable that the specific structure and working principle of the telescopic device 72 are well known to those skilled in the art, and common telescopic devices 72 include linear motors, telescopic cylinders, and telescopic hydraulic cylinders. At the same time, a heating device is provided in the baking box 71, and the heating device can be heated, and the specific heating temperature can be set according to actual needs.

[0081] In this embodiment, Figure 2 , Figure 5 , Figures 10 to 12 As shown, the baking oven 71 includes a box body 711, a conveyor belt 712 and a pair of rollers 713. The opening groove 7110 is set on the side wall of the box body 711, the conveyor belt 712 is rotatably installed on the box body 711 through the rollers 713, and the placement cavities 7120 are evenly distributed on the conveyor belt 712. A reduction device 600 is installed between the rotating device 41 and the baking oven 71, and the output end of the rotating device 41 is connected to the input end of the reduction device 600 through a one-way bearing, and the output end of the reduction device 600 is spline-connected to one of the rollers 713. When the rotating device 41 rotates forward, the reduction device 600 remains stationary through the one-way bearing; when the rotating device 41 rotates reversely, the reduction device 600 reduces the output speed of the rotating device 41, thereby driving the rollers 713 to drive the conveyor belt 712 to move a short distance, so that the next idle placement cavity 7120 is directly opposite to the clamping mechanism 4. Alternatively, when the rotating device 41 rotates forward, the reduction device 600 reduces the output speed of the rotating device 41, thereby driving the roller 713 to drive the conveyor belt 712 to move a short distance, so that the next idle placement cavity 7120 is opposite to the clamping mechanism 4; when the rotating device 41 rotates reversely, the reduction device 600 remains stationary through the one-way bearing.

[0082] Specifically, Figure 5 , Fig.10 and Fig.12 As shown, a third transmission wheel 413 is also installed at the output end of the rotating device 41, and a sixth transmission wheel 610 is installed at the input end of the reduction device 600 via a fourth one-way bearing 620; the third transmission wheel 413 and the sixth transmission wheel 610 can be connected by a gear meshing transmission, a belt transmission or a chain transmission; the output end of the reduction device 600 is spline-connected to one of the rollers 713 via a spline shaft 630, so that the baking oven 71 can also be transmission-connected to the reduction device 600 when moving.

[0083] When the rotating device 41 rotates forward, the fourth one-way bearing 620 is in a free state, so that the conveyor belt 712 remains stationary; when the rotating device 41 rotates reversely, the fourth one-way bearing 620 is in an engaged state, and then the reduction device 600 can drive the roller 713 to drive the conveyor belt 712 to move a set distance through the spline shaft 630 at the output end.

[0084] Alternatively, when the rotating device 41 rotates forward, the fourth one-way bearing 620 is in an engaged state, and then the reduction device 600 can drive the roller 713 to drive the conveyor belt 712 to move a set distance through the spline shaft 630 at the output end; when the rotating device 41 rotates reversely, the fourth one-way bearing 620 is in a free state, so that the conveyor belt 712 remains stationary.

[0085] It is understandable that the specific structure and working principle of the deceleration device 600 are well known to those skilled in the art, and the deceleration ratio of the deceleration device 600 is related to the number and spacing of the placement cavities 7120 in the baking oven 71. Assuming that the spacing between adjacent placement cavities 7120 is L, the deceleration device 600 can drive the conveyor belt 712 to move a distance of L every time the rotating device 41 rotates one circle, so that the next idle placement cavity 7120 can be moved to a set position.

[0086] It is also understandable that the specific number of the placement cavities 7120 can be selected according to the heating and curing time. Assuming that the time for the product 100 to complete the glue dispensing process is t, and the maximum time for the glue of the product 100 to be heated and cured is T; then the number of the placement cavities 7120 is at least T / t.

[0087] In this embodiment, Figure 2 and Fig.11 As shown, a material unloading component 8 is installed on the workbench 1 on the side of the baking oven 71 close to the clamping mechanism 4; the material unloading component 8 can correspond to the position of the placement cavity 7120 set in the baking oven 71, and then when the baking oven 71 moves toward the clamping mechanism 4, the material unloading component 8 can pass through the opening groove 7110 to push the cured product 100 in the placement cavity 7120 at the set position out of the baking oven 71.

[0088] Specifically, Fig.11 and Figures 17 to 19 As shown, the unloading component 8 includes a second guide rail 81 and a sliding block 82; the second guide rail 81 is installed on the workbench 1 and its extension direction is parallel to the extension direction of the baking oven 71; the sliding block 82 is slidably installed on the second guide rail 81 with an adjustable position, and a push rod 820 is arranged on the sliding block 82, and the push rod 820 corresponds to the height of the opening groove 7110, so that when the baking oven 71 moves toward the direction of the clamping mechanism 4, the push rod 820 can extend into the baking oven 71 to push the product 100 that has completed heating and curing at the set position out of the baking oven 71 for unloading.

[0089] It is understandable that, depending on the temperature in the oven 71 or the type of glue, the heating and curing time of different products 100 is also different. Therefore, the position of the sliding block 82 on the second guide rail 81 can be adjusted to realize the unloading of products 100 with different heating times. That is, after adjusting the position of the sliding block 82, the distance between the position of the placement cavity 7120 facing the push rod 820 and the position of the placement cavity 7120 for loading by the loading mechanism 5 changes, thereby adjusting the heating and fixing time of the product 100.

[0090] One of the embodiments of the present application is as follows: Figure 2 , Fig.13 , Fig.14 and Figures 17 to 22 As shown, the feeding mechanism 5 includes a pair of guide seats 51 symmetrically arranged on both sides of the clamped product 100 , a pair of clamping components 52 and a pair of swinging components 55 . The guide seat 51 is fixedly installed on the workbench 1, and a slide groove 510 is provided on the upper part of the guide seat 51. The clamping assembly 52 is slidably installed in the slide groove 510 and cooperated with the guide structure; a rotating shaft 512 is rotatably installed in the middle part of the guide seat 51, and the rotating shaft 512 is connected to the baking device 7 through a third transmission structure; the swing assembly 55 is correspondingly located on the side of the guide seat 51, the input end of the swing assembly 55 is connected to the rotating shaft 512 to form a crank rocker structure, and the output end of the swing assembly 55 is connected to the clamping assembly 52; when the baking device 7 approaches the clamping mechanism, the swing assembly 55 drives the feeding mechanism 5 to perform the first process and the second process under the drive of the third transmission structure; wherein, in the first process: the clamping assembly 52 moves toward the end of the product 100 and clamps; in the second process: the clamping assembly 52 drives the product 100 to move toward the baking device 7 and relaxes; when the baking device 7 is reversed and reset, the swing assembly 55 remains stationary through the third transmission structure.

[0091] In this embodiment, Fig.13 , Fig.16 and Figure 20 to Figure 22As shown, the guide structure includes a guide rod 525 and a guide groove 511 that are slidably matched. The guide rod 525 is elastically slidably installed on the clamping assembly 52; the guide groove 511 is arranged at the bottom of the slide groove 510, and the guide groove 511 includes a first groove section 5111, a second groove section 5112, a third groove section 5113 and a fourth groove section 5114 in the form of a parallelogram; wherein the first groove section 5111 and the third groove section 5113 are parallel to the axial direction of the product 100, and the two ends of the first groove section 5111 and the third groove section 5113 are connected through the inclined second groove section 5112 and the fourth groove section 5114 respectively; the third groove section 5113 is close to the product 100, the second groove section 5112 is smoothly connected with the first groove section 5111, and the depth of the second groove section 5112 is shallower than the depth of the adjacent end of the third groove section 5113; the fourth groove section 5114 is smoothly connected with the third groove section 5113, and the depth of the fourth groove section 5114 is shallower than the adjacent end of the first groove section 5111 depth of the adjacent end; when performing the first process, the clamping assembly 52 can slide along the first slot section 5111 toward the end of the product 100 through the guide rod 525, so that the clamping assembly 52 maintains a gap with the product 100; then, the clamping assembly 52 slides along the second slot section 5112 to the end of the third slot section 5113 through the guide rod 525, so that the clamping assembly 52 and the end of the product 100 are clamped; when performing the second process, the clamping assembly 52 can first slide along the third slot section 5113 through the guide rod 525, so that the clamping assembly 52 clamps the product 100 and moves it toward the baking oven 71; then, the clamping assembly 52 slides along the fourth slot section 5114 to the end of the first slot section 5111 through the guide rod 525, so that the clamping assembly 52 moves the product 100 to the corresponding placement cavity 7120 and releases it.

[0092] For ease of understanding, the specific working process of the guide structure may be described in detail below.

[0093] like Fig.16 As shown, the connection point between the first slot section 5111 and the fourth slot section 5114 is A, the connection point between the first slot section 5111 and the second slot section 5112 is B, the connection point between the second slot section 5112 and the third slot section 5113 is C, and the connection point between the third slot section 5113 and the fourth slot section 5114 is D. Among them, the depth of point A is greater than the depth of the fourth slot section 5114, and the depth of point C is greater than the depth of the second slot section 5112. At the same time, take the example of the forward rotation of the rotating device 41 driving the conveyor belt 712 to move.

[0094] Initially, the clamping mechanism 4 rotates forward to complete the dispensing process of the product 100; at the same time, the conveyor belt 712 moves a set distance L under the drive of the deceleration device 600, so that the next idle placement cavity 7120 faces the product 100. In this process, Fig.16 , Fig.17 and Fig. 20 As shown, the clamping assembly 52 is located at point A through the guide rod 525 ; at this time, there is a gap X between the clamping assembly 52 and the side wall of the product 100 to ensure that there is no interference between the clamping assembly 52 and the product 100 .

[0095] When the baking oven 71 moves a certain distance toward the clamping mechanism 4, Fig.16 As shown, the clamping assembly 52 is driven by the swing assembly to move from point A to point B through the guide rod 525; during this process, the clamping assembly 52 always maintains a gap X between it and the product 100.

[0096] Then, the baking box 71 continues to move toward the clamping mechanism 4 for a certain distance. Fig.16 , Fig.18 and Fig.21 As shown, the clamping assembly 52 is driven by the swing assembly to move from point B to point C through the guide rod 525; during this process, the clamping assembly 52 gradually approaches the product 100 until the product 100 is clamped.

[0097] Then, if Fig.18 and Fig.21 As shown, the rotating device 41 rotates in the reverse direction, and then the push rod 422 rotates in the reverse direction and drives the clamping claw assembly 423 to loosen the glue-dispensed product 100 through the driving structure, so that the product 100 is only clamped by the clamping assembly 52. ​​At the same time, the reverse rotation of the rotating device 41 can also drive the conveyor belt 712 in the baking oven 71 to move the next idle placement cavity 7120 to face the product 100 clamped by the clamping assembly 52.

[0098] Then, the baking box 71 continues to move toward the clamping mechanism 4 for a certain distance. Fig.16 As shown, the clamping assembly 52 is driven by the swing assembly to move from point C to point D through the guide rod 525; during this process, the clamping assembly 52 always maintains clamping with the product 100, and can move the product 100 toward the baking oven 71.

[0099] Then, the baking box 71 continues to move a distance toward the clamping mechanism 4 to the limit position. Fig.16 , Fig.19 and Fig. 22 As shown, the clamping assembly 52 is driven by the swing assembly to move from point D to point A through the guide rod 525; during this process, the clamping assembly 52 moves in a direction away from the product 100, and then releases the product 100 after the product 100 extends into the corresponding placement cavity 7120.

[0100] Finally, the oven 71 is driven by the telescopic device 72 to reset to the initial position; then the glue dispensing process of the next product 100 is carried out.

[0101] In this embodiment, Fig.11 , Fig.13 , Fig.14 and Figures 17 to 22 As shown, the third transmission structure includes a transmission gear 53 and a rack plate 73; the transmission gear 53 is mounted on the rotating shaft 512 through a third one-way bearing 54, and the rack plate 73 is fixedly mounted on the side wall of the box body 711 of the baking oven 71 and meshes with the transmission gear 53. When the baking oven 71 moves toward the direction of the clamping mechanism 4, the third one-way bearing 54 is in a meshing state, thereby driving the transmission gear 53 and the rotating shaft 512 to rotate synchronously to drive the swing assembly 55 to swing. When the baking oven 71 moves in a direction away from the clamping mechanism 4, the third one-way bearing 54 is in a free state, so that the rotating shaft 512 remains stationary.

[0102] In this embodiment, Fig.13 , Fig.14 and Figures 17 to 20 As shown, the swing assembly 55 includes a swing rod 551, a sleeve 552 and a crank 553; one end of the swing rod 551 is hinged to the workbench 1, and the other end of the swing rod 551 cooperates with the traction rod 5213 of the clamping assembly 52 through the provided traction groove 5510; the sleeve 552 is slidably sleeved on the middle part of the swing rod 551, one end of the crank 553 is fixed to the rotating shaft 512, and the other end of the crank 553 is hinged to the sleeve 552, thereby forming a crank swing rod mechanism. Therefore, when the rotating shaft 512 rotates, the crank 553 can drive the sleeve 552 to rotate in a circle, thereby driving the swing rod 551 to swing.

[0103] It can be understood that the meshing stroke of the rack plate 73 and the transmission gear 53 can drive the rotating shaft 512 to rotate one circle; that is, the swing rod 551 can swing to the extreme position and then return to the initial position during the rotating shaft 512 rotates one circle.

[0104] In this embodiment, Fig.13 and Fig.15As shown, the clamping assembly 52 includes a clamping block 521 and a pressing plate 522; a second mounting groove 5211 is provided on the side of the clamping block 521 close to the product 100, and a third mounting groove 5212 is provided on the side of the clamping block 521 close to the guide groove 511; the pressing plate 522 is slidably connected to the clamping block 521, and the pressing block 522 is slidably matched with the second mounting groove 5211 through a second sliding rod 5220, and a third spring 523 is also installed in the second mounting groove 5211, so that the pressing plate 522 and the clamping block 521 are elastically connected, and then the products 100 with different diameters can be clamped by the different compression amounts of the third spring 523. The guide rod 525 is elastically slidably installed in the third mounting groove 5212 through the fourth spring 524, so that when encountering guide grooves 511 of different depths, the guide rod 525 can be elastically slid to always keep matching with the guide groove 511. The traction rod 5213 is arranged on the other side of the clamping block 521 away from the product 100. The traction rod 5213 can pass through the slide groove 510 and cooperate with the traction groove 5110 on the rocker arm 551; the length of the traction groove 5110 is greater than the diameter of the traction rod 5213 to ensure that the rocker arm 551 does not interfere with the traction rod 5213 during the swinging process.

[0105] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
