Description

However, in the production process, the hand mold size on the same production line can only produce the same size or the same style. If other size or style gloves need to be produced, the glove mold needs to be replaced, and the parameters of the glove mold of the required size need to be adjusted, such as: the impregnation depth of small size impregnated gloves is much smaller than that of large size impregnated gloves. When the production line producing small size impregnated gloves needs to be immediately replaced to produce large size impregnated gloves, the mold needs to be replaced, and the parameters of each process such as methanol impregnation, glue impregnation, wrinkle agent impregnation and spraying need to be adjusted to adapt to the production process of large size glove mold.

[0049] The current impregnation production line needs workers to adjust the process parameters of other processes according to the size or style of the current mold after replacing the mold, which not only affects the production efficiency, but also increases the labor cost of the production unit.

[0050] Therefore, the utility model provides an intelligent impregnation production line, referring to Figures 1 to 3 The intelligent impregnation production line comprises a control system, a rack 1, a conveying device, an identification device 2 and a plurality of impregnation stations 3, wherein:

[0051] The conveying device is used for conveying the mold 100;

[0052] The identification device 2 and each impregnation station 3 are sequentially arranged on the rack 1 along the conveying direction of the mold 100, and the identification device 2 is arranged upstream of each impregnation station 3;

[0053] The identification device 2 is used for obtaining the shape information of the current mold 100 and feeding back the shape information to the control system;

[0054] The control system can control each impregnation station 3 and / or the conveying device to impregnate the articles on the mold 100 according to the process parameters matched with the shape information of the current mold 100.

[0055] It should be noted that the number of impregnation stations 3 can be one or more. The liquid material category at the impregnation station 3 can be any one of glue, penetrant and surface treatment material, or other categories. When the number of impregnation stations 3 is more than one, the liquid material categories at each impregnation station 3 can be the same or different. In addition, since the structure of each impregnation station 3 is similar when the number of impregnation stations 3 is more than one, Figures 1 to 3 Only the structure of one of the impregnation stations 3 is shown. The number of impregnation stations 3 and the liquid material category can be adjusted according to the impregnation requirements of the articles to be processed (such as gloves), which is not limited here.

[0056] It should be further noted that in order to improve production efficiency, a plurality of molds 100 (when the articles to be processed are gloves, the mold 100 is specifically a hand mold) are processed simultaneously in a group; The molds 100 in the same group are fixed side by side on a mold rod 200, and are driven and moved and rotated by the mold rod 200. Of course, each mold 100 can also be conveyed and processed separately.

[0057] In order to realize automatic conveying of the mold 100, the rack 1 is further provided with a conveying device for conveying the mold 100, the conveying device is controlled by the control system to drive the mold 100 to move to the identification device 2 and each impregnation station 3 in turn, and to make the mold 100 stay at the identification device 2 and each impregnation station 3; the control system controls the length of stay of the mold 100 at each impregnation station 3 according to the process parameters of the mold 100. The conveying device includes one or more of a chain transmission mechanism, a belt transmission mechanism, a mechanical gripper mechanism, and a multi-degree-of-freedom robot. The above transmission mechanisms are conventional transmission mechanisms, and their structures are not described in detail here.

[0058] The intelligent impregnation production line provided in the application adds an identification device 2 upstream of each impregnation station 3, which can obtain the shape information (the shape information can be one or more of the length, width, height, angle, attitude, etc. of the mold 100) of the current mold 100 through the identification device 2 before formally processing the article and feed the shape information back to the control system; the control system (such as a computer CPU) can adjust and judge each control instruction according to the needs, and after receiving the shape information of the current mold 100, it can identify and judge the size or style corresponding to the mold 100 and automatically make corresponding adjustments to the subsequent process parameters. In the production process from the first impregnation station 3 to the last impregnation station 3 of the production line, the control system can make the impregnation station 3 process according to the corresponding process parameters (the process parameters include the impregnation depth, the turning angle, the waiting time, the number of turns, etc. of the mold 100) when a mold 100 of different sizes reaches the impregnation station 3, realizing online switching of molds 100 of different sizes, thereby improving production efficiency, reducing labor costs per unit of production, and not needing to debug production, thereby reducing the number of defective products.

[0059] In some embodiments, the impregnation production line further includes a mold changing system for automatically changing the mold 100, through which online production switching can be realized, further improving the production switching efficiency. Exemplarily, the mold changing system includes a plurality of mold racks and a carrying device, wherein: the mold racks are placed with mold rods 200, and a plurality of molds 100 are installed side by side on each mold rod 200; the carrying device is used to take the mold rod 200 on the mold rack and place it at the feeding position of the rack 1. The carrying device can be a multi-degree-of-freedom manipulator or a six-axis robot with grippers.

[0060] In some optional embodiments, the number of the identification devices 2 is one and the identification device 2 is arranged upstream of all the dipping stations 3. Alternatively, the number of the identification devices 2 is multiple and the identification device 2 corresponds to the dipping station 3 one by one, and each identification device 2 is arranged at the front side of the corresponding dipping station 3. Of course, it is also possible to arrange that two or more adjacent dipping stations 3 share one identification device 2.

[0061] In the present embodiment, the number of the identification devices 2 is one and the identification device 2 is arranged upstream of all the dipping stations 3. After the control system identifies the size of the current mold 100, the control system starts to track the position of the mold 100 on the production line and makes a judgment when the mold 100 runs to each dipping station 3.

[0062] In the embodiment in which the identification device 2 corresponds to the dipping station 3 one by one, the size or type of the mold 100 can be identified and judged when the mold 100 runs to each dipping station 3.

[0063] In some embodiments, the identification device 2 comprises an image acquirer, which can be one of a camera, a camera head and a scanner. The identification device 2 is used to take an image of the current mold 100 and feed the image to the control system. The control system has pre-stored process parameters corresponding to molds 100 of different sizes, and after receiving the image of the current mold 100, the control system can identify and analyze the image to determine the size of the current mold 100 and call the process parameters matched with the size of the current mold 100, and then control each dipping station 3 to dip the articles on the mold 100 according to the corresponding process parameters.

[0064] It should be noted that when multiple molds 100 are processed as a group, the identification device 2 only needs to take an image of one of the molds 100 in the same group.

[0065] As an optional embodiment, the identification device 2 is located above or below the mold 100 to be taken. Figure 1 In the illustrated embodiment, the identification device 2 is suspended on the rack 1 by a mounting rod and located above the mold 100 to be taken, and when the mold 100 is conveyed to the working position of the identification device 2, the identification device 2 takes the image of the mold 100 from top to bottom. Of course, the identification device 2 can also be arranged below the rack 1, and the identification device 2 takes the image of the mold 100 from bottom to top.

[0066] In some embodiments, the identification device 2 further comprises a light source, and the light-emitting end of the light source faces the shooting area of the image acquirer. The light source can light the shooting area, making the image of the mold 100 clearer and easier to identify, and solving the problem of low identification accuracy in dim light.

[0067] With reference to the above Figure 1 Each of the dipping stations 3 comprises a tank 31 for storing liquid material required for dipping, which can be any one of glue, penetrating agent and surface treatment material. Each of the dipping stations 3 further comprises a height detection mechanism 32 for detecting and limiting the lifting height of the tank 31 or the lowering height of the mold 100, and a dipping material lifting mechanism 33, wherein the detection stop height of the height detection mechanism 32 can be adjusted according to the process parameters matched by the current mold 100 shape information; the dipping material lifting mechanism 33 is configured to drive the tank 31 to lift or drive the mold 100 to lower to the detection stop height.

[0068] In the glue dipping production line, there are two ways to dip the mold 100 into the tank 31, the first way is to lift the tank 31 while the mold 100 is stationary, and the second way is to lower the mold 100 while the tank 31 is stationary. For the first way, the height detection mechanism 32 is used to detect and limit the lifting height of the tank 31, and the dipping material lifting mechanism 33 is configured to drive the tank 31 to lift to the detection stop height. For the second way, the height detection mechanism 32 is used to detect and limit the lowering height of the mold 100, and the dipping material lifting mechanism 33 is configured to drive the mold 100 to lower to the detection stop height.

[0069] In this embodiment, the height detection mechanism 32 is specifically used to detect and limit the liquid level in the tank 31, and further detect and limit the lifting height of the tank 31; the dipping material lifting mechanism 33 is configured to drive the tank 31 to lift to the detection stop height. When the mold 100 is dipped into the tank 31, the mold 100 is stationary, and the dipping material lifting mechanism 33 drives the tank 31 to lift, so that the mold 100 gradually dips into the tank 31. Compared with directly detecting the height of the tank 31, the embodiment indirectly controls the height of the tank 31 by detecting the liquid level in the tank 31, which can more accurately control the dipping depth of the mold 100. The dipping material lifting mechanism 33 comprises a tank driving source, which can be a motor or a piston cylinder, the body of which is mounted on the rack 1, and the power output end thereof can be directly connected with the tank 31 or indirectly connected with the tank 31 through chain wheel and chain, screw nut and other lifting transmission structures. The dipping material lifting mechanism 33 is prior art, which is not described in detail here.

[0070] In the structure, the height detection mechanism 32 and the dipping material lifting mechanism 33 are signal-connected with the control system. Taking one of the dipping stations 3 as an example, when the mold 100 reaches above the material pool 31 of the dipping station 3, the control system determines the process parameters corresponding to the mold 100, and then controls the height detection mechanism 32 to move, so that the detection stop height of the height detection mechanism 32 matches the process parameters of the mold 100; then, the control system controls the dipping material lifting mechanism 33 to drive the material pool 31 to be lifted (or drives the mold 100 to be lowered), and in this process, the mold 100 gradually dips into the material pool 31, and the lifting of the material pool 31 stops when the liquid level in the material pool 31 reaches the detection stop height of the height detection mechanism 32, so that the dipping depth of the mold 100 can be accurately controlled, and the processing quality of the product can be ensured.

[0071] Referring to Figure 4 and Figure 5 In some embodiments, the height detection mechanism 32 includes a lifting adjusting assembly arranged on the rack 1 and a first proximity switch 321 in transmission connection with the lifting adjusting assembly. The lifting adjusting assembly is configured to drive the first proximity switch 321 to a specified height according to the process parameters matched with the current mold 100, so as to realize the adjustment of the detection stop height of the height detection mechanism 32.

[0072] Optionally, the first proximity switch 321 is one of an optical switch, an ultrasonic proximity switch, a tuning fork proximity switch, and a radar proximity switch. In this embodiment, the first proximity switch 321 is specifically an optical switch.

[0073] In some embodiments, the lifting adjusting assembly includes a first lifting driving source 322. The body of the first lifting driving source 322 is arranged on the rack 1, the power output end of the first lifting driving source 322 is in transmission connection with the first proximity switch 321, and the first proximity switch 321 is suspended above the material pool 31. The first lifting driving source 322 is configured to be able to drive the first proximity switch 321 to rise and fall.

[0074] The first lifting driving source 322 can be a motor or a piston cylinder (including an oil cylinder, a gas cylinder, and an electric cylinder). When the first lifting driving source 322 is a motor, the output shaft of the motor can be indirectly connected to the first proximity switch 321 through a transmission structure such as a screw nut, a connecting rod, a gear belt, a gear rack, etc., so as to convert the torque of the motor into a linear torque. When the first lifting driving source 322 is a piston cylinder, the extension end of the piston cylinder can be directly connected to the first proximity switch 321, or can be indirectly connected to the first proximity switch 321 through a transmission structure.

[0075] As an optional embodiment, the lifting adjusting assembly comprises a lead screw 323 and a nut screwed on the lead screw 323, the lead screw 323 is in transmission connection with the power output end of the first lifting driving source 322, and the nut is connected with the first proximity switch 321.

[0076] And / or, the lifting adjusting assembly further comprises a guide rail 325 arranged on the rack 1 and a sliding block slidingly arranged on the guide rail 325, the sliding block is connected with the first proximity switch 321.

[0077] And / or, the lifting adjusting assembly further comprises a second lifting driving source 326, the body of the second lifting driving source 326 is in transmission connection with the power output end of the first lifting driving source 322, and the power output end of the second lifting driving source 326 is in transmission connection with the first proximity switch 321; the second lifting driving source 326 is configured to drive the first proximity switch 321 to lift.

[0078] In this embodiment, the lifting adjusting assembly comprises a lead screw 323 and a nut screwed on the lead screw 323, the lead screw 323 is connected with the power output end of the first lifting driving source 322 (specifically, a motor) through a shaft coupling, and the nut is connected with the first proximity switch 321. The transmission mode of the lead screw and the nut can accurately control the lifting height of the first proximity switch 321, and the accuracy is within 1mm (this accuracy meets the tolerance range of the immersion depth). When the molds 100 of different sizes reach each immersion station 3, the lifting adjusting assembly drives the first proximity switch 321 to reach the corresponding detection stop height in advance, so as to limit the lifting height of the material pool 31 (that is, limit the immersion depth of the mold 100), and meet the problem that the immersion depths of different size molds 100 are different. In order to limit the movement track of the first proximity switch 321 and improve the installation stability of the first proximity switch 321, the lifting adjusting assembly further comprises a guide rail 325 arranged on the rack 1 and a sliding block slidingly arranged on the guide rail 325, the sliding block is connected with the first proximity switch 321, so that the first proximity switch 321 can only slide up and down along the length direction of the guide rail 325.

[0079] On the basis of the above structure, the first lifting driving source 322, the lead screw 323, the nut, the guide rail 325 and the sliding block are integrally arranged on the same mounting seat, and the mounting seat is fixedly arranged on the rack 1 by bolts.

[0080] Further, in the embodiment, the lifting adjusting assembly further comprises a second lifting driving source 326, which is specifically a pneumatic cylinder. The lifting adjusting assembly further comprises a sliding plate 324 fixedly connected with the nut and the sliding block. The body of the second lifting driving source 326 is fixedly installed on the sliding plate 324 through bolts. The telescopic end of the second lifting driving source 326 is fixedly connected with the first proximity switch 321 through connecting plates, bolts, nuts and other connecting structures. In other embodiments, the second lifting driving source 326 can also be an electric cylinder or an oil cylinder.

[0081] In the embodiment, a two-stage lifting driving structure is arranged, wherein the first-stage lifting driving structure comprises the first lifting driving source 322, the lead screw 323 and the nut, and the second-stage lifting driving structure comprises the second lifting driving source 326. When the control system identifies the process parameters corresponding to the current mold 100, if the immersion depth of the current mold 100 is different from that of the previous mold 100, the control system first controls the first lifting driving source 322 to start, drives the second lifting driving source 326 and the first proximity switch 321 to lift to a specified height through the lead screw 323 and the nut. Then, the control system controls the second lifting driving source 326 to start, drives the first proximity switch 321 to descend to the specified height. At this time, the detection and stop height of the first proximity switch 321 matches the immersion depth corresponding to the current mold 100, so that the lifting height of the liquid pool 31 can be controlled through the first proximity switch 321. If the immersion depth of the current mold 100 is the same as that of the previous mold 100, the control system directly controls the second lifting driving source 326 to start, drives the first proximity switch 321 to descend to the specified height. At this time, the detection and stop height of the first proximity switch 321 matches the immersion depth corresponding to the current mold 100. After the mold 100 is immersed, the control system controls the second lifting driving source 326 to start, drives the first proximity switch 321 to lift to the initial height, so that the first proximity switch 321 avoids the moving path of the mold 100, and thus the mold 100 can be smoothly conveyed to the next station. Since the two-stage lifting driving structure is arranged, for the molds 100 of the same size, only the second-stage lifting driving structure needs to be started before each immersion, which greatly reduces the response time of the height detection mechanism 32.

[0082] In other embodiments, the second lifting driving source 326 can not be arranged, and the first proximity switch 321 can also be driven to lift to avoid the moving path of the mold 100 through the first lifting driving source 322.

[0083] Continuing to refer to Figure 3, each of the dipping stations 3 comprises an angle detection mechanism 34 and a turnover mechanism 35, wherein: the angle detection mechanism 34 is configured to detect and limit the turnover angle of the mold 100, and the stop angle of the angle detection mechanism 34 can be adjusted according to the process parameters matched by the current mold 100; the turnover mechanism 35 is configured to drive the mold 100 to turn over until the turnover angle of the mold 100 reaches the stop angle.

[0084] The turnover mechanism 35 is a conventional setting of the dipping production line, and will not be described in detail here. During the turnover of the mold 100 by the turnover mechanism 35, when the mold 100 is turned over to the turnover angle matched by the mold 100, the mold 100 is just at the stop angle of the angle detection mechanism 34, at this time, the angle detection mechanism 34 is triggered, and the control system controls the turnover mechanism 35 to stop turning over the mold 100.

[0085] In some embodiments, the angle detection mechanism 34 comprises a second proximity switch 341. The second proximity switch 341 can be an optical switch or a Hall switch. When the second proximity switch 341 is a Hall switch, a magnet for triggering the Hall switch needs to be installed on the mold 100 or the mold rod 200.

[0086] In some embodiments, the stop angle of the angle detection mechanism 34 is adjusted manually. Different sizes of the mold 100 have a greater impact on the lifting height of the tank 31, but generally have little impact on the turnover angle of the mold 100, and only in the case of a large size span or special requirements for the product, the turnover angle of the mold 100 will be changed. Since the turnover angle of the mold 100 is generally unchanged, for a small number of cases where the turnover angle of the mold 100 needs to be changed, the stop angle of the angle detection mechanism 34 can be adjusted manually.

[0087] As an embodiment of manually adjusting the second proximity switch 341, as shown in Figure 6 and Figure 7 , the angle detection mechanism 34 further comprises a first adapter plate 342, a second adapter plate 343, and a locking member 344, the first adapter plate 342 is fixedly installed on the rack 1 and hinged to one end of the second adapter plate 343, the second proximity switch 341 is fixed to the other end of the second adapter plate 343, and the locking member 344 is connected between the first adapter plate 342 and the second adapter plate 343 and can lock or release the relative position of the two. The detection end of the second proximity switch 341 can face the mold 100 or the mold rod 200; in this embodiment, the detection end of the second proximity switch 341 faces one end of the length direction of the mold rod 200.

[0088] In this embodiment, the first adapter piece 342 is L-shaped, the horizontal section of which is fixed on the rack 1 by bolts, and the vertical section and one end of the second adapter piece 343 are sleeved on a screw rod 345, and the screw rod 345 is fixedly connected with the vertical section by a nut. The locking members 344 are nuts screwed on the screw rod 345, and the number of the locking members 344 is two, which are arranged on the two sides of the thickness direction of the second adapter piece 343 respectively. By screwing the two nuts, the second adapter piece 343 can be clamped or released. When it is necessary to adjust the position of the second proximity switch 341, the two locking members 344 are screwed to release the second adapter piece 343, and then the second proximity switch 341 can be adjusted.

[0089] As another embodiment for manually adjusting the second proximity switch 341, a plurality of installation positions are provided on the rack 1, and the plurality of installation positions are matched with the process parameters of the mold 100 of different sizes. The second proximity switch 341 is fixedly arranged at one of the installation positions by bolts.

[0090] Of course, in some other embodiments, the detection stop angle of the angle detection mechanism 34 can be adjusted automatically. The angle detection mechanism 34 further comprises a rotary driving source configured to drive the second proximity switch 341 to rotate eccentrically according to the process parameters matched with the shape information of the current mold 100, so as to realize the automatic adjustment of the detection stop angle of the second proximity switch 341. The rotary driving source can be an electric motor, an oil cylinder, a piston cylinder, etc. The power output end of the rotary driving source can be directly connected to the second proximity switch 341, or indirectly connected to the second proximity switch 341 through a transmission structure. For example, the rotary driving source is an electric motor, the body of the electric motor is fixedly arranged on the rack 1, an eccentric connecting plate is fixedly sleeved on the output shaft of the electric motor, and the second proximity switch 341 is fixedly arranged on the end of the eccentric connecting plate away from the output shaft of the electric motor.

[0091] In addition to the above embodiments, in some embodiments, when the mold 100 is replaced, the second proximity switch 341 can also not be adjusted (i.e. the angle adjustment assembly and the rotary driving source can not be provided), but the turning angle of the mold 100 is adjusted by the control system. The specific implementation is as follows: taking the second proximity switch 341 as a reference, when the mold 100 is turned, the control system controls the turning mechanism 35 to rotate the mold 100 forward, and when the second proximity switch 341 is triggered, the mold 100 is continuously rotated forward or reversely by a compensation angle X. The above forward and reverse directions are relative directions, and the compensation angle X can be positive or negative. The specific value of the compensation angle is adjusted according to the process parameters matched with the mold 100. When the compensation angle X is positive, the mold 100 is continuously rotated forward by the compensation angle X when the second proximity switch 341 is triggered. When the compensation angle X is negative, the mold 100 is continuously rotated reversely by the compensation angle X when the second proximity switch 341 is triggered.

[0092] With the processing flow of one set of molds as an example, the production flow of the intelligent sizing production line provided by one specific embodiment of the present application is as follows:

[0093] S1: The mold rod 200 together with the mold 100 thereon is placed at the feeding position of the rack 1 by the mold changing system, and the control system controls the conveying device on the rack 1 to drive the mold 100 to convey;

[0094] S2: During the conveying of the mold rod 200 on the rack 1, the mold rod 200 first passes through the identification device 2, the image of one of the molds 100 (or multiple molds) on the mold rod 200 is acquired by the identification device 2, and the image (which contains the shape information of the mold 100) is fed back to the control system. The control system identifies the image, judges the size or style corresponding to the mold 100, and then calls the process parameters (including the flip angle, the dipping depth, the waiting time, the number of flips, etc.) matched by the mold 100. After the matching is completed, the control system starts to track the position of the mold 100 on the production line and makes a judgment at each dipping station 3;

[0095] S3: When the mold 100 is conveyed to the first dipping station 3, the control system judges whether the process parameters of the mold 100 are the same as those of the mold 100 dipped previously;

[0096] If the flip angle of the mold 100 is different from that of the mold 100 dipped previously, the control system controls the rotary drive source to drive the second proximity switch 341 to rotate to a specified angle, at which time the detection and stop angle of the second proximity switch 341 matches the flip angle corresponding to the mold 100. Then, the control system controls the flip mechanism 35 to drive the mold rod 200 together with the mold 100 thereon to flip until the mold rod 200 stops when the second proximity switch 341 is triggered;

[0097] If the flip angle of the mold 100 is the same as that of the mold 100 dipped previously, the control system controls the flip mechanism 35 to directly drive the mold rod 200 together with the mold 100 thereon to flip until the mold rod 200 stops when the second proximity switch 341 is triggered;

[0098] If the dipping depth of the mold 100 is different from that of the mold 100 dipped previously, the control system first controls the first lifting drive source 322 to start, drives the second lifting drive source 326 and the first proximity switch 321 to lift to a specified height through the lead screw 323 and the nut, and then controls the second lifting drive source 326 to start, drives the first proximity switch 321 to descend to a specified height, at which time the detection and stop height of the first proximity switch 321 matches the dipping height corresponding to the mold 100. Subsequently, the control system controls the dipping material lifting mechanism 33 to drive the material pool 31 to lift up;

[0099] If the current mold 100 has the same impregnation depth as the previous mold 100, the control system directly controls the second lifting driving source 326 to start, drives the first proximity switch 321 to descend to a specified height; then, the control system controls the impregnation lifting mechanism 33 to drive the material pool 31 to rise;

[0100] During the process of the material pool 31 rising, the mold 100 after turning gradually immerses in the material pool 31 until the liquid surface in the material pool 31 triggers the first proximity switch 321 to stop; during the impregnation process, the control system controls the rising time of the material pool 31 according to the waiting time of the mold 100, and controls the mold 100 to repeatedly perform corresponding actions according to the impregnation and turning times of the mold 100;

[0101] After the impregnation is completed, the control system controls the impregnation lifting mechanism 33 to drive the material pool 31 to descend to the initial position, at the same time, the control system controls the second lifting driving source 326 to lift the first proximity switch 321 to the initial position to avoid the mold 100, and then the control system controls the conveying device to convey the mold 100 to the next process;

[0102] S4: Repeat step S3 when the mold 100 is conveyed to each subsequent impregnation station 3, until the mold 100 completes all processing procedures.

[0103] As described above, the rubber impregnation production line provided by the present application solves the problem that the production line cannot produce multiple sizes simultaneously, saves the labor cost of changing molds 100 and adjusting corresponding process parameters, improves the efficiency of changing molds, and reduces the defective products generated by trial production; for the production process, reduces (even eliminates) the human factors of process adjustment, makes the quality of rubber glove products more stable, and greatly improves the intelligent degree of the labor protection rubber glove industry.
