[0050] The present invention provides for reference Figures 1 to 10 , in the embodiments of the present invention, a fully automatic PVC drip glue production line, which sequentially includes according to the work process distribution:

[0051] Drip glue mechanism 1: used for drip glue molding of products in a mold in the form of drip glue;

[0052] Baking mold mechanism 2: used for drying the products after drip glue molding (different drying times and temperatures can be set for different types of products);

[0053] Cooling mold mechanism 3: used for rapid cooling of the dried products and molds (different cooling times can be set for different types of products)

[0054] Mold picking mechanism 4: used for mold picking work on products;

[0055] Second feeding belt 5 and first feeding belt 6: used for the transfer work of the processed molds;

[0056] The first feeding belt 6 is connected to the dispensing mechanism 1 to realize the device cycle.

[0057] It also includes: a control panel for controlling each device to work. The control panel is mainly used to control the automatic or manual working states of each mechanism and to set the heating time and temperature of the mold baking mechanism 2, the cooling time of the mold cooling mechanism 3, and other working states.

[0058] During processing: The mold is placed on the first feeding belt 6. The first feeding belt 6 conveys the mold and places it on the dispensing mechanism 1. Then, the dispensing mechanism 1 performs dispensing and forming of the product on the mold. Then, the dispensing mechanism 1 sends the mold into the mold baking mechanism 2, and the mold baking mechanism 2 dries the product in the mold in a specific temperature environment for a certain period of time. After drying, the mold baking mechanism 2 sends it into the mold cooling mechanism 3 to cool the product and the mold. After cooling for a certain period of time, the mold cooling mechanism 3 sends the mold into the mold picking mechanism 4, and the product is picked out of the mold through the mold picking mechanism 4. The product is placed into an external material box, and the mold is sent into the second feeding belt 5 by the mold picking mechanism 4, and then sent back to the first feeding belt 6 through the second feeding belt 5 and finally sent back to the dispensing mechanism 1 by the first feeding belt 6 to realize the cycle.

[0059] Further, the first feeding belt 6 includes: a first feeding belt body 61. The beginning of the first feeding belt body 61 is connected to the second feeding belt 5, and the end of the first feeding belt body 61 extends to the side of the dispensing mechanism 1;

[0060] A pushing cylinder 62 is installed at the end side position of the first feeding belt body 61, and the piston rod of the pushing cylinder 62 extends towards the dispensing mechanism 1. A baffle plate 63 is installed at the end of the first feeding belt body 61. A control sensor 64 is installed on the baffle plate 63.

[0061] The mold is placed in the first feeding belt body 61 and is driven forward by the first feeding belt body 61 until it abuts against the baffle plate 63, thereby triggering the control sensor 64, causing the first feeding belt body 61 to stop working and the pushing cylinder 62 to start working to push the mold onto the bearing plate 112 of the dispensing mechanism 1 to complete the feeding. Then, the pushing cylinder 62 resets and waits for the next feeding work.

[0062] Further, the epoxy resin dispensing mechanism 1 includes: a workbench 11, on which a set of epoxy resin dispensing Y-axis sliding modules 19 are installed; on the epoxy resin dispensing Y-axis sliding modules 19, a bearing plate 112 for placing an epoxy resin dispensing mold is installed, and a proximity sensor 10 is arranged on the bearing plate 112;

[0063] On one side of the bearing plate 112 away from the first feeding belt 6, an adjusting stop bar 114 is installed; a number of adjusting holes are arranged on the bearing plate 112, and the adjusting stop bar 114 can be fixedly fitted with each adjusting hole through screws. The adjusting stop bar 114 can be fixedly fitted with each adjusting hole through screws; the placement position of the mold pushed into by the pushing cylinder 62 is adjusted by adjusting the position of the adjusting stop bar 114.

[0064] At the rear end of the bearing plate 112, a relief groove (not shown in the figure) is arranged along its length direction, and a lifting stop bar 111 that is lifted and lowered by a cylinder is arranged in the relief groove;

[0065] On the workbench 11 at the front end position of the bearing plate 112, a set of clamping cylinders 113 are installed. A clamping push plate (not shown in the figure) is arranged on the piston rod of the clamping cylinder 113, and the piston rod of the clamping cylinder 113 makes a telescopic movement towards the lifting stop bar 111;

[0066] The mold is pushed into the bearing plate 112 by the pushing cylinder 62 of the first feeding belt 6. When being pushed in, the mold abuts against the adjusting stop bar 114 to make the mold straighten;

[0067] At the same time, the mold triggers the proximity sensor 10, and the proximity sensor 10 drives the clamping cylinder 113 to work. The clamping cylinder 113 pushes the clamping push plate forward to push the mold so that the mold abuts against the lifting stop bar 111, thereby realizing the positioning work of the mold; the mold loading and positioning action is completed;

[0068] At the upper end of the epoxy resin dispensing Y-axis sliding modules 19, a set of cross beam brackets 17 straddling the upper end of the epoxy resin dispensing Y-axis sliding modules 19 are arranged, and a set of epoxy resin dispensing X-axis sliding modules 19 are installed on the cross beam brackets 17; on the sliding part of the epoxy resin dispensing X-axis sliding modules 19, an epoxy resin dispensing Z-axis lifting module 15 is installed;

[0069] On the lifting part of the epoxy resin dispensing Z-axis lifting module 15, a horizontally arranged epoxy resin dispensing gun bracket 13 is installed. A number of epoxy resin dispensing gun holders 14 are arranged on the epoxy resin dispensing gun bracket 13, and epoxy resin dispensing guns (not shown in the figure) are installed in the epoxy resin dispensing gun holders 14; a material cup holder 16 is also installed on the cross beam bracket 17. A number of cup grooves 161 are formed in the material cup holder 16, and a material cup (not shown in the figure) is placed in each cup groove 161. A set of epoxy resin dispensing groups are formed by connecting one material cup and one epoxy resin dispensing gun;

[0070] An UV lamp 12 that irradiates vertically downward is also installed on the epoxy resin dispensing gun bracket 13;

[0071] After completing the loading and positioning action, the dispensing Y-axis sliding module 19, the dispensing X-axis sliding module 19 and the dispensing Z-axis lifting module 15 are controlled by an automated control program to drive the mold and the dispensing gun to perform three-axis motion coordination, so as to realize the forming process of the dispensing product in each forming cavity of the mold;

[0072] During processing: After the dispensing gun finishes the topcoat processing in each forming cavity, the dispensing Y-axis sliding module 19, the dispensing X-axis sliding module 19 and the dispensing Z-axis lifting module 15 drive the UV lamp 12 to scan the topcoat in each forming cavity one by one, so as to achieve the effect of preheating and curing it; Avoid the mixing of the topcoat and the primer during the secondary dispensing process (primer processing), which affects the forming rate of the product.

[0073] Then, the dispensing Y-axis sliding module 19, the dispensing X-axis sliding module 19 and the dispensing Z-axis lifting module 15 are controlled by the automated control program again to drive the mold and the dispensing gun to perform three-axis motion coordination again to realize the processing of the primer; Complete the dispensing processing action;

[0074] A material frame 118 is arranged at the rear end of the dispensing Y-axis sliding module 19, and a pair of material frame guide rails 113 extending backward to the baking mold mechanism 2 are arranged on both sides of the rear end of the dispensing Y-axis sliding module 19; A corresponding sliding seat 116 is slidably fitted on the material frame guide rail 113; A pushing material cylinder 120 for pushing the sliding seat 116 to move along the material frame guide rail 113 towards the baking mold mechanism 2 is respectively arranged on both sides of the dispensing Y-axis sliding module 19;

[0075] A material frame lifting cylinder 119 is installed on the sliding seat 116, and the piston rod of the material frame lifting cylinder 119 vertically moves up and down and is fixedly connected to the lower side end of the material frame 118;

[0076] A number of groups of downward-extending material frame lifting guide rails 117 are also installed on both sides of the material frame 118, and a guiding slider 116 corresponding to the material frame lifting guide rail 117 is fixedly installed on the sliding seat 116;

[0077] After completing the dispensing processing action, the dispensing Y-axis sliding module 19 drives the bearing plate 112 and the mold to move to the lower end of the material frame 118; Then, the material frame lifting cylinder 119 drives the material frame 118 to descend to surround and block the four sides of the mold on the bearing plate 112; Then, the pushing material cylinder 120 drives the material frame 118 to move towards the baking mold mechanism 2; At the same time, the material frame 118 will drive the mold to move towards the baking mold mechanism 2; Before moving, the lifting strip 111 descends into the avoidance groove for avoidance, and after the movement is completed, the lifting strip rises and resets again.

[0078] After the mold is carried into the baking mold mechanism 2 by the material frame 118 and leaves the bearing plate 112, the dispensing Y-axis sliding module 19 leaves and drives the bearing plate 112 to reset to receive the next group of molds;

[0079] After the material frame 118 drives the mold into the baking mold mechanism 2, the material frame lifting cylinder 119 drives the material frame 118 to rise, and the material pushing cylinder 120 drives the material frame 118 to exit the baking mold mechanism 2 and reset, completing the mold feeding work.

[0080] Furthermore, a delay sensor (not shown in the figure) for detecting the working state of the baking mold mechanism 2 is also provided at the midpoint position of the dispensing Y-axis sliding module 19; during the mold feeding process, when the delay sensor senses that there is still a mold being dried and processed in the baking mold mechanism 2, the delay sensor will control the dispensing Y-axis sliding module 19 to pause working until the baking mold mechanism 2 sends out the mold to be processed, and then the delay sensor starts the dispensing Y-axis sliding module 19 again to perform the mold feeding work.

[0081] Furthermore, several groups of pressure gauges 122 for viewing the dispensing groups are arranged at the front end position of the workbench 11, and a pressure regulating valve 123 corresponding to each pressure gauge 122 is provided at the lower end of each pressure gauge 122. The relative pressure gauges 122 and pressure regulating valves 123 correspond to a group of dispensing groups; during use, the pressure regulating valve 123 cooperates with the pressure gauge 122 to adjust the pressure of the dispensing group to meet different dispensing requirements.

[0082] Furthermore, several pressure regulating valves 121 for adjusting the height of the dispensing gun are provided at the rear end position of the crossbeam support 17, and one pressure regulating valve 121 corresponds to the dispensing gun of a group of dispensing groups.

[0083] Furthermore, the baking mold mechanism 2 includes: a feeding mechanism respectively communicating with the dispensing mechanism 1 and the mold cooling mechanism 3; the feeding mechanism includes: two groups of symmetrically arranged stainless steel conveying chain groups 27, and four stainless steel conveying chain push rods 28 are arranged between the two groups of stainless steel conveying chain groups 27; the four stainless steel conveying chain push rods 28 are evenly distributed on the stainless steel conveying chain groups 27; among them, the four stainless steel conveying chain push rods 28 are distributed at the front and rear ends and the middle positions of the upper and lower ends of the stainless steel conveying chain groups 27; when the stainless steel conveying chain groups 27 work, they will drive the stainless steel conveying chain push rods 28 located at this position to the next position (for example: the stainless steel conveying chain groups 27 work will drive the stainless steel conveying chain push rod 28 originally located at the starting position to the upper end setting);

[0084] A baking device is also installed between the stainless steel conveying chain groups 27. The baking device includes: two groups of baking furnace groups 21, and each group of baking furnace groups 21 includes an upper baking furnace 22 and a lower baking furnace 26. A baking cavity is formed between the upper baking furnace 22 and the lower baking furnace 26; the baking cavities of the two groups of baking furnace groups 21 are communicated; the stainless steel conveying chain push rods 28 are driven by the stainless steel conveying chain groups 27 to pass through the baking cavity;

[0085] The material frame guide rail 113 extends into the first baking chamber (i.e., the baking chamber of the oven group 21 close to the dispensing mechanism 1).

[0086] During the working process, after the mold is brought into the first baking chamber by the material frame 118, it is dried at high temperature by the oven group 21. After drying for a certain time, the stainless steel conveying chain group 27 drives the stainless steel conveying chain push rod 28 to move forward, and then the mold in the first baking chamber is pushed into the second baking chamber by the stainless steel conveying chain push rod 28 for continuous drying; this makes the position of the first baking chamber vacant so that the dispensing mechanism 1 can send the subsequent molds in.

[0087] The drying temperature in the first baking chamber is the same as that in the second baking chamber, and the baking time of the mold in the two baking chambers is the same; that is, in actual processing through the double-station baking device, there will always be molds being dried in the two baking chambers. While ensuring the drying time of the products in the mold, it can also enable the molds after subsequent dispensing to quickly enter the drying work, effectively avoiding the situation where the dispensing mechanism 1 waits for drying during the processing; thereby improving the production efficiency of the processing.

[0088] Similarly, during the working process, the stainless steel conveying chain group 27 drives the stainless steel conveying chain push rod 28 to move forward, and then the mold in the first baking chamber is pushed into the second baking chamber by the stainless steel conveying chain push rod 28. If there is a mold in the second baking chamber, the mold will be pushed outwards by the stainless steel conveying chain push rod 28.

[0089] The delay sensor of the dispensing Y-axis sliding module 19 is mainly used to detect whether there is a mold being dried in the first baking chamber. If there is still a mold being dried in the first baking chamber, the delay sensor will control the dispensing Y-axis sliding module 19 to pause working until the first baking chamber sends out the dried mold, and then the delay sensor starts the dispensing Y-axis sliding module 19 again for mold feeding work.

[0090] At the discharge port position of the baking chamber, there is a baking oven push-up and down cylinder 24 installed. The piston rod of the baking oven push-up and down cylinder 24 moves up and down. A baking oven push cylinder 25 is installed on the piston rod of the baking oven push-up and down cylinder 24. The piston rod of the baking oven push cylinder 25 extends towards the inside of the baking chamber. A baking oven push plate 23 is installed on the piston rod of the baking oven push cylinder 25.

[0091] During the process of the mold being pushed outwards by the stainless steel conveying chain push rod 28 in the second baking chamber, due to the structural characteristics of the stainless steel conveying chain push rod 28, the mold cannot be completely pushed out of the baking chamber.

[0092] Therefore, after the mold is pushed outwards by the stainless steel conveyor chain push rod 28, the oven push cylinder 25 operates to move the oven push plate 23 to the upper rear end of the mold, and then the oven push lifting cylinder 24 drives it to descend so that the oven push plate 23 moves to the rear end of the oven. Finally, the oven push cylinder 25 drives the oven push plate 23 to return outward. During the return process, the oven push plate 23 pushes the mold out and drops it into the mold cooling mechanism 3, completing the mold drying and the work of sending out the dried mold.

[0093] Further, the mold cooling mechanism 3 includes: a mold cooling water tank 31 arranged at the rear end of the mold baking mechanism 2; a partition net 35 is installed at the upper end of the mold cooling water tank 31; a water spray head 32 that sprays upward is installed at the middle position of the mold cooling water tank 31;

[0094] A drainage groove 33 is formed at the side end of the mold cooling water tank 31, and a drainage port (not shown in the figure) for drainage is provided in the drainage groove 33;

[0095] The mold cooling mechanism 3 further includes: a cold water tank 34, the water outlet of the cold water tank 34 is connected to the water spray head 32 through a pipeline and a water pump; the water inlet of the cold water tank 34 is connected to the drainage port through a pipeline;

[0096] After the mold is dried, the mold is pushed by the oven push plate 23 driven by the oven push cylinder 25 onto the mold cooling water tank 31 and is cushioned by the partition net 35;

[0097] Then the water pump starts to work, pumps out the cold water in the cold water tank 34, and sprays it on the lower end face of the mold by the water spray head 32, thereby quickly cooling the mold. The sprayed water will overflow in the mold cooling water tank 31 and flow into the drainage groove 33 and return to the cold water tank 34 from the drainage port, realizing water circulation;

[0098] Within the set cooling time, the water spray head 32 will continuously spray water for cooling. After the cooling is completed, the water pump is turned off and the water spray head 32 stops working to complete the cooling work;

[0099] A mold cooling push cylinder 62 that makes a pushing movement towards the mold picking mechanism 4 is arranged at the side end of the mold cooling water tank 31;

[0100] After the cooling work is completed, the mold cooling push cylinder 62 operates to push the module into the mold picking mechanism 4, and then the mold cooling push cylinder 62 resets and waits for the subsequent mold feeding.

[0101] Further, the mold picking mechanism 4 includes: a sprocket roller group 41, a mold picking device;

[0102] The sprocket drum group 41 includes: a set of powered sprocket drums 412 and several sets of unpowered sprocket drums 413; a chain is used for transmission between the powered sprocket drum 412 and one set of unpowered sprocket drums 413, and chains are also used for transmission between the individual unpowered sprocket drums 413, thereby achieving the effect that the powered sprocket drum 412 drives the unpowered sprocket drums 413 to work.

[0103] The beginning of the sprocket drum group 41 is connected to the cooling die mechanism 3, and the second feeding belt 5 is arranged on the end side of the sprocket drum group 41;

[0104] A clamping lifting cylinder 40 is installed on one side of the end of the sprocket drum group 41 close to the second feeding belt 5. The piston rod of the clamping lifting cylinder 40 moves up and down. A clamping cylinder 411 is installed on the piston rod of the clamping lifting cylinder 40. The piston rod of the clamping cylinder 411 extends upward to the upper side of the sprocket drum group 41. A clamping pressing plate 48 is installed on the piston rod of the clamping cylinder 411;

[0105] A die pushing rodless cylinder 49 is installed at the lower end of the end position of the sprocket drum group 41. The piston rod of the die pushing rodless cylinder 49 moves from the side far from the second feeding belt 5 to the side close to the second feeding belt 5; A clamping pushing plate 46 is installed on the piston rod of the die pushing rodless cylinder 49. The upper end of the clamping pushing plate 46 branches out and passes through between the drums of the sprocket drum group 41;

[0106] The needle picking device includes: a needle picking frame 42, and a needle picker 45 for picking the product out of the die is installed on the needle picking frame 42; A swing cylinder 44 for driving the needle picker 45 to swing is arranged on the needle picking frame 42;

[0107] The needle picking device further includes: a three-axis driving module 43 for driving the needle picker 45 to perform XYZ three-axis movement and a scraper 414 arranged at the end of the sprocket drum group 41.

[0108] An opto-electronic inductor 47 is installed at the end position of the sprocket drum group 41;

[0109] After the die enters the die picking mechanism 4, the die is driven forward by the sprocket drum group 41 until the opto-electronic inductor 47 is triggered. After the opto-electronic inductor 47 is triggered, it drives the clamping cylinder 411 and the die pushing rodless cylinder 49 to work simultaneously, so that the clamping pressing plate 48 and the clamping pushing plate 46 move closer to the middle of the sprocket drum group 41 at the same time until the clamping pressing plate 48 and the clamping pushing plate 46 clamp the die to achieve positioning and clamping;

[0110] After positioning and clamping, the three-axis drive module 43 drives the pick needle 45 to move to at least the position of the molding cavity of the mold. Then, the swing cylinder 44 drives the pick needle 45 to swing to pick out the product. The picked product will hang on the pick needle 45. Then, the three-axis drive module 43 drives the pick needle 45 to move from the upper end of the scraper 414 to the outer side of the end of the sprocket roller group 41 (where the material box is placed). Then, the three-axis drive module 43 drives the pick needle 45 to descend and at the same time drives the pick needle 45 to move backward to reset, so that the product contacts the scraper 414. The product hanging on the pick needle 45 is scraped off by the scraper 414 and falls into the material box to realize the pick-mold blanking action. This is repeated to complete the pick-mold blanking work;

[0111] After completing the pick-mold blanking work, after the pick needle device finishes processing, the clamping cylinder 411 resets. At the same time, the clamping lifting cylinder 40 drives the clamping cylinder 411 to lift, so that a material passing gap is formed between the clamping push plate 46 and the unpowered sprocket roller group 41. Then, the mold pushing rodless cylinder 49 works for the second time to push. The mold on the unpowered sprocket roller group 41 is pushed into the second feeding belt 5 through the material passing gap by the clamping push plate 46 to complete the feeding work after pick-molding; then the mold pushing rodless cylinder 49 drives the clamping push plate 46 to reset and waits for the subsequent mold loading.

[0112] Further, the second feeding belt 5 includes: a second feeding belt body 51, and both ends of the second feeding belt body 51 are respectively connected to the pick-mold mechanism 4 and the first feeding belt 6;

[0113] After the mold enters the second feeding belt body 51, since the second feeding belt body 51 drives the mold to be transported to the first feeding belt 6, the effect of transfer is achieved;

[0114] A second photoelectric inductor 55 is also installed on the second feeding belt body 51;

[0115] During the transfer process, the second photoelectric inductor 55 continuously senses the feeding state of the first feeding belt 6. If there are still untransported mold products on the first feeding belt 6, the second photoelectric inductor 55 controls the second feeding belt body 51 to stop working to avoid the situation of material accumulation on the first feeding belt 6; otherwise, it controls the work normally.

[0116] Furthermore, a reduction motor 53 and a speed regulator 54 for adjusting the feeding speeds of the first feeding belt body 61 and the second feeding belt body 51 are respectively installed on the first feeding belt body 61 and the second feeding belt body 51; to achieve the effect of different transmission speeds according to different product molds and the effect of stopping during work.

[0117] Further, a pair of adjustable adjusting baffles 52 are provided on both sides of the first feed belt body 61 and the second feed belt body 51, and the position between the adjusting baffles 52 is adjusted to achieve the effect of transmission guidance for different product mold sizes.
