Description

[0002] During the production process, workpieces need to be glued. In the traditional gluing process, the degree of automation is not high, and each workstation requires multiple technicians to perform manual operation, which makes the gluing accuracy not high enough and the efficiency is relatively low, resulting in increased production costs and waste of human resources.

[0003] To this end, automated equipment is gradually being used to replace manual automatic gluing. The process is: the product to be glued is transported from the loading area to the gluing area by a robot, and then the product to be glued is pressed with the glue raw material in the gluing area by a robot to complete the gluing. This method of gluing has high gluing accuracy and efficiency, and can reduce costs.

[0004] However, when gluing some smaller products, in order to improve the gluing efficiency, it is necessary to glue multiple small-sized products in the same batch at the same time. And gluing multiple smaller products at the same time requires considering the accuracy of the fit between the products and the gluing area after the products are transported by the robot to the gluing area. For example, after arranging multiple products in the loading area, the robot transports these arranged products to the gluing area. The gluing area needs to arrange multiple rubber raw materials according to the positions of these products. In order to ensure the accuracy of gluing, this method of gluing still requires manual arrangement of the rubber raw materials according to the distribution of the products before automatic gluing. Due to the large number and small size of the rubber raw materials, the arrangement process of the rubber raw materials will also cause great waste of manpower costs and low production efficiency.

[0034] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0039] like Figure 1 and Figure 2 As shown, this embodiment provides a variable pitch positioning mechanism 10, including a bottom plate 11, a driving rod 13, a first driving unit 12 and a plurality of positioning parts 14. The first driving unit 12 can drive the driving rod 13 to move linearly along its length direction, and the plurality of positioning parts 14 are arranged on the bottom plate 11 in sequence along the length direction of the driving rod 13, and the positioning parts 14 can move on the bottom plate 11. A positioning hole 141 is provided on the positioning part 14, and the positioning hole 141 is provided between the top and the bottom of the positioning part 14. The top of the positioning part 14 is used to carry the rubber material, and the bottom of the positioning part 14 is in contact with the bottom plate 11. In the initial state, these positioning parts 14 are in a close fitting state, and the tops of the plurality of positioning parts 14 together constitute the bearing surface of the rubber material. The rubber material is placed on the bearing surface formed by the tops of the plurality of positioning parts 14, and the rubber material is pre-cut between the positioning parts 14, and the rubber material on the positioning part 14 and the top of the positioning part 14 are fixed in the horizontal direction. The driving rod 13 is inserted into the positioning holes 141 of the plurality of positioning parts 14. The driving rod 13 is provided with a plurality of stoppers 131 at intervals along the length direction thereof. When the driving rod 13 moves linearly, the stoppers 131 can drive the positioning parts 14, so that the plurality of positioning parts 14 are arranged in sequence according to the spacing of the plurality of stoppers 131. Since the rubber raw material has been pre-cut and is fixed to the positioning parts 14 in the lateral direction, the rubber raw material is torn at the pre-cut position during the process of the plurality of positioning parts 14 being distributed at intervals under the drive of the driving rod 13, so that a portion of the rubber raw material is on the top of each positioning part 14. The spacing of the stopping parts 131 on the driving rod 13 corresponds to the spacing between the multiple products to be glued, which can ensure that the positions of the products to be glued and the original rubber materials correspond in the subsequent gluing process. In the preparation for gluing, it is only necessary to manually place the pre-cut rubber materials on the multiple positioning parts 14 in a close and fitting state according to the set position. There is no need to place the multiple rubber materials in the gluing positions one by one according to the positions of the multiple products to be glued in batch gluing. This can improve the gluing efficiency and reduce labor costs, and can ensure that the positions of the products to be glued and the original rubber materials correspond accurately.

[0040] Specifically, for the first driving unit 12 to drive the driving rod 13 to move, the first driving unit 12 includes a first driving member 121 and a driving plate 122. The first driving member 121 can be a cylinder, and the cylinder is fixedly connected to the bottom of the bottom plate 11. One side of the driving plate 122 has an extension plate 1221 downwardly. The bottom plate 11 is provided with a through slot 111 on one side of the driving plate 122, and the extension direction is consistent with the length direction of the driving rod 13. The extension plate 1221 of the driving plate 122 passes through the through slot 111 and is fixedly connected to the output shaft of the cylinder of the first driving unit 12, so that The driving plate 122 remains relatively fixed with the output shaft of the cylinder. The driving direction of the output shaft of the cylinder is consistent with the length direction of the driving rod 13, and can drive the driving plate 122 to move linearly along the length direction of the driving rod 13. One end of the driving rod 13 is fixedly connected to the middle part of the driving plate 122. The driving plate 122 drives the driving rod 13 to move linearly during the movement, and then the driving rod 13 drives the multiple positioning parts 14 to move through the stopping part 131 during the linear movement, so that the multiple positioning parts 14 are arranged in sequence according to the spacing of the multiple stopping parts 131.

[0041] In order to drive the plurality of positioning portions 14 through the stopper 131 on the driving rod 13, and arrange the plurality of positioning portions 14 according to the spacing between the plurality of stopper 131, the method adopted in this embodiment is as follows: in the arrangement direction of the plurality of positioning portions 14, the apertures of the positioning holes 141 of the plurality of positioning portions 14 gradually decrease, and the positioning holes 141 are coaxial, the plurality of stopper 131 on the driving rod 13 are cylindrical, and the cross-sectional areas of the stopper 131 gradually decrease in the arrangement direction of the plurality of positioning portions 14, such as Figure 1 and Figure 2 As shown in the figure, the arrangement direction of the positioning parts 14 is from the left side to the right side of the multiple positioning parts 14 in the figure. In this direction, the aperture of the positioning hole 141 of the positioning part 14 gradually decreases, and the cross-sectional area of ​​the stopping part 131 also gradually decreases. One stopping part 131 corresponds to one positioning part 14 drive, and the cross-sectional area of ​​the stopping part 131 in the corresponding group is larger than the area of ​​the positioning hole 141 of the positioning part 14, but the cross-sectional area of ​​the stopping part 131 is smaller than the area of ​​the positioning hole 141 of the positioning part 14 on the left side. In the process of the driving rod 13 moving linearly, due to the smaller cross-sectional area of ​​the stopping part 131 on the right side, the stopping part 131 on the right side can pass through the positioning hole 141 of the positioning part 14 on the left side, and in the subsequent movement process, it is offset with the positioning part 14 on the right side, driving the positioning part 14 on the right side to move linearly, and finally the multiple positioning parts 14 are arranged in sequence according to the spacing of the multiple stopping parts 131, and the positioning parts 14 and the stopping parts 131 are staggered on the driving rod 13.

[0042] Furthermore, Figure 1As shown in , after the first driving unit 12 drives the driving rod 13 to move linearly, it can also drive the driving rod 13 to move linearly in the opposite direction. One end of the driving rod 13 is fixedly connected to the positioning portion 14 at the end (i.e., the rightmost side in this embodiment) of the arrangement direction of the plurality of positioning portions 14, so as to drive the positioning portion 14 to move linearly. During the process in which the first driving unit 12 drives the driving rod 13 to move linearly in the opposite direction, since the cross-sectional area of ​​the stopper 131 in this direction is smaller than the size of the positioning hole 141 of the positioning portion 14 on the left side, the stopper 131 on the driving rod 13 will not interact with the positioning portion 14 during the process in which the driving rod 13 moves in the opposite direction. During the process in which the positioning portion 14 on the rightmost side gradually contacts the positioning portion 14 on the left side as the driving rod 13 moves, and pushes the positioning portion 14 on the left side to move to the left side, so that the plurality of positioning portions 14 are finally brought close to each other and restored to the initial state. At this time, the adhesive raw material is manually placed on the plurality of positioning portions 14 in the close and fitted state to carry out a new round of gluing.

[0043] At the same time, after the stopper 131 of the driving rod 13 drives the plurality of positioning parts 14 to move, in order to prevent the positioning parts 14 from continuing to move due to inertia, resulting in the final rubber material and the position of the product to be glued not corresponding to each other, such as Figure 3 and Figure 4 As shown in ( Figure 3 In order to facilitate the display of the structure, the positioning part 14 is hidden in the figure). The variable distance positioning mechanism 10 provided in this embodiment also includes a distance-fixing tooth part 15, which is arranged on the bottom plate 11 below the plurality of positioning parts 14. The positioning part 14 can be a part of the bottom plate 11 or can be fixedly installed on the bottom plate 11. The height of the plurality of positioning parts 14 gradually decreases in the arrangement direction thereof. The height mentioned here refers to the height of the length, width and height of the positioning part 14 itself, and does not refer to the installation height of the positioning part 14 on the driving rod 13. The tops of the plurality of positioning parts 14 are flush, and the spacing tooth part 15 is provided with a plurality of protrusions 151 with successively larger heights at intervals in the arrangement direction of the positioning parts 14. When the plurality of positioning parts 14 are moved from left to right under the drive of the driving rod 13, since the protrusion 151 on the far left has the smallest height, and the positioning part 14 on the far right has the smallest height, when the tops of the plurality of positioning parts 14 are flush, the bottom of the positioning part 14 is farthest from the spacing tooth part 15. When the positioning part 14 on the far right passes the protrusion 151 on the far left, the protrusion 151 will not interfere with the positioning part 14, and the positioning part 14 on the far right will not be limited until it moves to the protrusion 151 with the largest height on the far right, and cannot continue to move to the right. At this time, the two sides of the positioning part 14 are respectively limited by the stopping part 131 of the driving rod 13 and the protrusion 151 of the spacing tooth part 15, so that the positioning part 14 is firmly kept in the required position to ensure the accuracy of subsequent glue sticking.

[0044] The rubber material is kept horizontally fixed on the positioning part 14, such as Figure 5 and Figure 6 As shown in , the positioning part 14 includes a connecting rod 142, a mounting member 143 and a positioning pin 144. A through hole is provided on the connecting rod 142, and a blind hole is provided on the mounting member 143. The through hole of the mounting hole is aligned with the axis of the blind hole of the mounting member 143. The connecting rod 142 is detachably mounted on the top of the mounting member 143 by the positioning pin 144 penetrating the through hole of the connecting rod 142 and the blind hole of the mounting member 143. In this way, the positioning pin 144 can fix the connecting rod 142 and the mounting member 143 in the horizontal direction, while the connecting rod 142 and the positioning pin 144 can be separated in the vertical direction. The positioning hole 141 of the positioning part 14 is provided on the mounting member 143. When the rubber material is attached to the positioning part 14, it is located on the connecting rod 142 of the positioning part 14. The connecting rod 142 and the mounting member 143 are fixed in the horizontal direction by the positioning pin 144. When the driving rod 13 drives the mounting member 143 to move, the connecting rod 142 can also move together with the positioning pin 144, and the positioning pin 144 can be used as a connection part and a reference part for fixing the rubber material on the positioning part 14. For example, a hole is opened on the rubber material, and the hole of the rubber material is aligned with the positioning pin 144 and inserted, so that the positioning pin 144 and the rubber material can be fixed in the horizontal direction. When the positioning part 14 is driven to move and separate by the driving rod 13, since a part of the rubber material is fixed on the positioning pin 144 of the positioning part 14 in the horizontal direction, and the positioning part 14 is separated from each other, the rubber material can be automatically torn at the pre-cutting position. In addition, the position of the positioning pin 144 can be a reference for the standard position of the rubber material laying. The loading personnel lay the rubber material on the positioning part 14 according to the position of the positioning pin 144, thereby improving the accuracy of the laying of the rubber material.

[0045] In addition, after the adhesive raw material and the product to be glued are glued, the adhesive of the adhesive raw material is attached to the product, while the release paper of the adhesive raw material is still on the positioning part 14. In order to conveniently remove the release paper and prepare for the next round of gluing, the variable pitch positioning mechanism 10 in this embodiment also includes a second driving unit 16, and the second driving unit 16 includes two second driving members 161 and two connecting rod pressing blocks 162. The two second driving members 161 are arranged on the bottom plate 11 and located on both sides of the positioning part 14. The two second driving members 161 are respectively connected to the two connecting rod pressing blocks 162. The connecting rod pressing block 162 is provided with a accommodating space 1621, and the accommodating space 1621 is connected to the outside in the direction toward the positioning part 14. This accommodating space 1621 forms a slide groove, and the two ends of the connecting rod 142 slide in the slide grooves of the connecting rod pressing blocks 162 on both sides of the positioning part 14 respectively. The second driving member 161 can be a cylinder, and the second driving member 161 has an output shaft, which can make a linear reciprocating movement on the second driving member 161. The second driving member 161 is located below the connecting rod pressure block 162, and the output shaft of the second driving member 161 can contact the connecting rod pressure block 162 and push the connecting rod pressure block 162 to rise when it extends toward the connecting rod pressure block 162. In the process of the connecting rod pressure block 162 rising, the connecting rod 142 is driven to rise, and the connecting rod 142 is separated from the mounting member 143 during the rising process, and when the connecting rod 142 rises to a height higher than the height of the positioning pin 144, the connecting rod 142 and the positioning pin 144 can also be separated. When the connecting rod 142 is separated from the positioning pin 144, the release paper of the rubber raw material on the connecting rod 142 loses the limiting effect of the positioning pin 144, and the release paper falls off the connecting rod 142.

[0046] At the same time, if Figure 5 As shown, the variable pitch positioning mechanism 10 provided in this embodiment also includes a third driving unit 18 and a cushion block 17. The cushion block 17 is located below the positioning portion 14. The third driving unit 18 can drive the cushion block 17 to rise and fall. When the plurality of positioning portions 14 are spaced apart under the drive of the driving rod 13, the third driving unit 18 drives the cushion block 17 to rise, so that the cushion block 17 is located between adjacent positioning portions 14, providing support for the product to be glued. Figure 7As shown in , it also includes a fourth drive unit 19, a first mounting plate 181 and a second mounting plate 182. The third drive unit 18 can drive the first mounting plate 181 to rise and fall. The fourth drive unit 19 is installed on the first mounting plate 181 and can drive the second mounting plate 182 to rise and fall. The third drive unit 18 and the fourth drive unit 19 can be cylinders, and the cushion block 17 is arranged on the second mounting plate 182. After the driving rod 13 drives the positioning part 14 to move, there is a gap between the positioning parts 14. At this time, the third drive unit 18 drives the first mounting plate 181 to rise. During the process of the first mounting plate 181 rising, the fourth drive unit 19 and the second mounting plate 182 are driven to rise, and then the cushion block 17 is driven to rise between the multiple positioning parts 14 to provide support for the product during the gluing process. When the third drive unit 18 drives the first mounting plate 181 to rise and drives the second mounting plate 182 and the cushion block 17 to rise, the fourth drive unit 19 drives the second mounting plate 182 to rise, so that the product is fully in contact with the rubber material during the bonding process, so that the product and the rubber material are fully bonded to the preset parameters.

[0047] In summary, the variable distance positioning mechanism 10 provided in this embodiment can conveniently and efficiently arrange the rubber raw materials according to the set position, and the arrangement accuracy is high, which improves efficiency and reduces labor costs.

[0048] like Figure 8 As shown, the present embodiment further provides an automatic gluing device, including a feeding mechanism 20, a gluing mechanism 30 and the variable distance positioning mechanism 10 as described above, the feeding mechanism 20 is used to place the products to be glued according to the set margins, the gluing mechanism 30 moves the products to be glued on the feeding mechanism 20 to the variable distance positioning mechanism 10 and the margins of the products to be glued are kept fixed during the operation, and after being moved into place, the products to be glued are bonded with the adhesive raw material on the positioning portion 14 after the distance is changed on the variable distance positioning mechanism 10.

[0049] The gluing mechanism 30 includes a first slide rail 31 and a gluing unit 32. The first slide rail 31 is located above the variable-distance positioning mechanism 10 and extends along the length direction of the driving rod 13. The gluing unit 32 is slidably installed on the first slide rail 31. The gluing unit 32 batches the products to be glued from the feeding mechanism 20 onto the variable-distance positioning mechanism 10.

[0050] Among them, Fig. 9As shown, the gluing unit 32 includes a slider 321, a fifth driving unit 322 and a gluing member 325. The fifth driving unit 322 is fixedly mounted on the slider 321. The slider 321 is slidably mounted on the first slide rail 31. The slider 321 drives the fifth driving unit 322 to move together. The gluing member 325 is mounted on the fifth driving unit 322. The fifth driving unit 322 can drive the gluing member 325 to rise and fall. The gluing member 325 is used for batch operation of the products to be glued on the feeding mechanism 20 and can tightly press the products to be glued and the original glue material during the process of attaching the products to be glued and the original glue material. Exemplarily, the fifth driving unit 322 can be a cylinder, and the gluing member 325 can be a suction cup capable of vacuum adsorption. The products to be glued are transported in batches through the adsorption effect of the gluing member 325.

[0051] Furthermore, since the products to be glued are transported in batches, in order to ensure that the products to be glued do not move during transportation, the positioning is accurate in the subsequent gluing process, such as Figure 8 , Figures 10 to 12 As shown, the automatic glue sticking device provided in this embodiment further includes a transfer mechanism 40 , and the transfer mechanism 40 includes a support seat 41 , a transfer plate 42 , an adhesive sheet 43 and a transfer film 45 . The transfer plate 42 is provided with a plurality of transfer slots 421 for placing the products 1 to be glued according to the set variable pitch. The feeding mechanism 20 moves the products 1 to be glued to the transfer slots 421 of the transfer plate 42 while maintaining the margins. The number of adhesive sheets 43 is consistent with the number of products 1 to be glued, and adhesive is provided on the front and back of the adhesive sheets 43. The adhesive sheets 43 are attached to the transfer film 45 through the front. After the feeding mechanism 20 moves the products 1 to be glued to the transfer slots 421, the transfer film 45 is manually covered on the transfer plate 42. The transfer film 45 adheres the products 1 to be glued to the transfer film 45 in batches through the attached plurality of adhesive sheets 43. The gluing mechanism 30 moves the transfer film 45 with the products 1 to be glued to the variable pitch positioning mechanism 10. In order to ensure that the transfer film 45 and the product 1 to be glued in the transfer groove 421 of the transfer plate 42 are accurately aligned, alignment holes are opened around the transfer film 45 and the transfer plate 42, and the transfer mechanism 40 also includes an alignment plug-in 46. When covering the transfer film 45, the alignment plug-in 46 is inserted into the alignment holes of the transfer film 45 and the transfer plate 42 to ensure that the transfer film 45 and the transfer plate 42 are accurately aligned, thereby ensuring that the adhesive sheet 43 on the transfer film 45 and the product 1 to be glued in the transfer groove 421 of the transfer plate 42 are accurately aligned.

[0052] Furthermore, Fig. 9 as well as Fig.10 As shown, the base plate 11 of the variable pitch positioning mechanism 10 is provided with a first guide groove 112 (see Figure 1), a second guide groove 44 is provided on the transfer plate 42 of the transfer mechanism 40, and a positioning member 323 matching the guide groove is provided on the glue sticking member 325 of the glue sticking mechanism 30. When the positioning member 323 is inserted into the guide groove, the product to be glued on the glue sticking mechanism 30 is aligned with the positioning portion 14 of the variable pitch positioning mechanism 10 or the transfer groove 421 of the transfer mechanism 40. In this way, when the glue sticking member 325 of the glue sticking mechanism 30 takes and puts the product to be glued on the transfer mechanism 40 and the variable pitch positioning mechanism 10, the positioning member 323 can be aligned with the guide groove to ensure the alignment accuracy of the product to be glued and the raw material of the glue.

[0053] At the same time, if Fig. 9 As shown, the glue-applying mechanism 30 also includes an assembly plate 324, the positioning member 323 includes a positioning shaft 3231, an elastic reset member 3232, the assembly plate 324 is fixedly connected to the output end of the fifth driving unit 322, the fifth driving unit 322 can drive the assembly plate 324 to rise and fall, the glue-applying member 325 is installed on the lower surface of the assembly plate 324, and the glue-applying member 325 rises and falls together with the assembly plate 324. At least two apex corners of the assembly plate 324 are provided with assembly holes, which are light holes. The positioning shaft 3231 is penetrated through the assembly holes, and the positioning shaft 3231 is provided with two limiting portions 32311 with a cross-sectional area larger than the area of ​​the assembly hole at intervals along its length direction. The limiting portion 32311 located at the top on the positioning shaft 3231 abuts against the upper surface of the assembly plate 324, and the two ends of the elastic return member 3232 abut against the lower surface of the assembly plate 324 and the limiting portion 32311 of the positioning shaft 3231 at the bottom, respectively. During the matching process of the positioning shaft 3231 of the positioning member 323 with the first guide groove 112 and the second guide groove 44 of the variable pitch positioning mechanism 10 and the transfer mechanism 40, the elastic return member 3232 on the positioning shaft 3231 can guide the matching of the positioning shaft 3231 and the guide grooves (referring to the first guide groove 112 and the second guide groove 44, the same below) by deformation, thereby improving the positioning matching accuracy. The bottom of the positioning shaft 3231 is the positioning block 32312. The cross-sectional area of ​​the positioning block 32312 gradually increases in the direction gradually moving away from the variable pitch positioning mechanism 10 below. The guide groove matches the shape of the positioning block 32312. The cross-sectional area of ​​the guide groove gradually decreases from top to bottom, which facilitates the positioning shaft 3231 to be inserted into the guide groove during the positioning matching process.

[0054] The feeding mechanism 20 moves the product to be glued to the transfer mechanism 40, such as Figures 13 to 15As shown, the feeding mechanism 20 includes a driving module 21 and an operating module 22. The driving module 21 includes a second slide rail 211 and a motor 212. The extension direction of the second slide rail 211 is perpendicular to the length direction of the driving rod 13. The operating module 22 includes an operating frame 222, a sixth driving unit 223, a feeding plate 224 and an adsorption plate 221. The motor 212 drives the operating frame 222 to make a linear reciprocating movement on the second slide rail 211. The adsorption plate 221 is installed on the operating frame 222 and the sixth driving unit 223 can drive the adsorption plate 221 to move up and down. The loading plate 224 is located below the adsorption plate 221. The loading plate 224 is provided with a plurality of loading troughs 2241 for placing the products to be glued. When the adsorption plate 221 is driven by the sixth driving unit 223 and descends to fit with the loading plate 224, the adsorption plate 221 adsorbs the products to be glued in the loading troughs 2241 of the loading plate 224 through the adsorption effect and moves it on the second slide rail 211 to the transfer plate 42 of the transfer mechanism 40, thereby completing the transfer of the products to be glued.

[0055] In summary, the automatic gluing device provided in this embodiment can complete the gluing of multiple products to be glued in batches with high precision and low labor cost.
