DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Example 1

[0032] Reference Figure 1-Figure 7 A gluing tool comprises: a workbench and a material table, a rectangular opening 2 is opened on the top of the workbench 1, and the rectangular opening 2 is used to accommodate and fix the material table 3. The material table 3 is accurately placed in the rectangular opening 2, and is designed to support the cover plate to be processed to ensure the stability of the cover plate during the processing.

[0033] Two rotating seats 9 are installed on the top of the workbench 1, and it is ensured that the two are parallel and appropriately spaced. A first screw 11 is set to rotate between the two rotating seats 9. The motor 10 is fixed at an appropriate position of the workbench 1, and its output end is fixedly connected to one end of the first screw 11. The moving frame 5 is designed to be threaded on the first screw 11, so that when the motor 10 is started, it can drive the first screw 11 to rotate, thereby driving the moving frame 5 to move linearly along the top of the workbench 1.

[0034] An electric push rod 7 is fixedly installed on the top of the moving frame 5. The output end of the electric push rod 7 is connected to a connecting frame 8, and a plurality of suction cups are installed at the bottom of the connecting frame 8, which are used to firmly grasp the cover plate in the adsorption state. At the same time, in order to ensure the stability of the connecting frame 8 during the lifting process, a first guide rod 6 is also slidably installed on the top of the moving frame 5, and the bottom end of the first guide rod 6 is fixedly connected to the connecting frame 8, which plays a role of guidance and support.

[0035] The glue coating mechanism includes: a mounting frame 12 is fixedly arranged on the top of the workbench 1. Three mounting holes 23 are provided on the top of the mounting frame 12, and a glue gun barrel 13 is installed in each mounting hole 23. In order to ensure the stability of the glue gun barrel 13, a detachable fixing plate 24 is also provided on the top of the mounting frame 12, which can be connected by bolts, and the three glue gun barrels 13 are accurately positioned by the fixing plate 24.

[0036] Inside the mounting frame 12, a support plate 25 is fixedly arranged, and the top of the support plate 25 passes through a position limiting cover 26 corresponding to the glue gun barrel 13. The bottom of each position limiting cover 26 contacts the bottom of the corresponding glue gun barrel 13 to ensure the stability of the glue gun barrel 13. The top of the position limiting cover 26 passes through a second screw rod 27, and the top end of the second screw rod 27 is rotatably sleeved with a stop plate 32 located in the glue gun barrel 13.

[0037] When gluing is required, the second screw rod 27 is driven to rotate and move upward by an external driving mechanism. As the second screw rod 27 rises, the abutment plate 32 also moves upward, gradually squeezing the glue in the glue gun barrel 13, causing it to flow out from the glue outlet of the glue gun barrel 13, and completing the gluing operation. Since the three second screw rods 27 are all connected to the moving frame 5 by transmission, the cover plate can be automatically and continuously glued during the process of the moving frame 5 driving the cover plate to move, realizing a fast and accurate gluing operation.

[0038] A waist-shaped hole 37 is provided on the top of the workbench 1 along its length. A connecting column 20 is slidably installed in the waist-shaped hole 37, and the top end of the connecting column 20 is fixedly connected to the moving frame 5 by welding or bolts. In this way, the horizontal movement of the moving frame 5 is achieved by sliding the connecting column 20 in the waist-shaped hole 37.

[0039] A connecting plate 21 is fixedly sleeved on the outer wall of the connecting column 20. A rack 22 is fixedly mounted on one side edge of the connecting plate 21 by welding or bolts.

[0040] A sliding ring 28 is slidably sleeved on the outer wall of each second screw rod 27. The three sliding rings 28 are connected by multiple synchronous wheels 16 and double-sided synchronous belts 17. In this way, when one of the sliding rings 28 rotates, the other two sliding rings 28 will be driven to rotate synchronously.

[0041] A gear 29 is fixedly sleeved on the outer wall of one of the sliding rings 28. The gear 29 meshes with the rack 22 on the connecting plate 21. Therefore, when the moving frame 5 drives the connecting column 20 to move in the waist-shaped hole 37, the connecting plate 21 and the rack 22 will move accordingly. Due to the meshing relationship between the gear 29 and the rack 22, the movement of the rack 22 will drive the gear 29 to rotate, and then drive the three second screws 27 to rotate synchronously through the synchronous transmission mechanism. In order to ensure that the glue coating stops during the resetting process of the moving frame 5, the gear 29 is sleeved on the corresponding sliding ring 28 through a one-way bearing.

[0042] The positioning mechanism comprises: two first clamping plates 14 are slidably mounted on the top of the workbench 1. The two first clamping plates 14 are respectively located on both sides of the workbench 1 and are used to clamp the bracket.

[0043] A connecting rod 36 is rotatably mounted at both ends of each first clamping plate 14. The other ends of the two connecting rods 36 on the same side are rotatably connected to the same second clamping plate 15. In this way, a four-bar linkage is formed between the second clamping plate 15 and the two first clamping plates 14.

[0044] A protrusion 19 is fixedly mounted on one side of the mobile frame 5 and is used in conjunction with one of the first clamping plates 14 or the second clamping plates 15. When the mobile frame 5 moves in the horizontal direction, the protrusion 19 will drive the second clamping plate 15 connected thereto to move. Due to the characteristics of the four-bar linkage, the movement of the second clamping plate 15 will drive the two first clamping plates 14 to move synchronously through the connecting rod 36, thereby achieving the clamping and positioning of the bracket or other components to be positioned.

[0045] The present application can be used in the field of glass plate positioning, and can also be used in other fields applicable to the present application.

[0046] Example 2

[0047] refer to Figure 1-Figure 7 , improved on the basis of Example 1: a glue tool with fast and accurate positioning, which is applied to the field of glass plate positioning, a plurality of limit strips 18 are fixedly installed on the top of the material table 3. These limit strips 18 are arranged according to the size and shape of the cover plate to ensure that the cover plate can be stably placed between the plurality of limit strips 18 to achieve preliminary positioning.

[0048] A plurality of universal wheels 4 are installed at the bottom of the material platform 3. These universal wheels 4 are not only convenient for moving and adjusting the position of the material platform 3, but also have a braking function. When the material platform 3 needs to be fixed, the universal wheels 4 can be locked by the braking device to prevent the material platform 3 from moving accidentally.

[0049] In order to realize the quick reset and stable clamping function of the first clamping plate 14 and the second clamping plate 15: two parallel fixing bars 33 are fixedly installed along the length direction of the workbench 1. The two fixing bars 33 serve as the basis for support and guidance.

[0050] Two second guide rods 34 are slidably installed on one side of each fixing bar 33. The sliding direction of the second guide rods 34 is consistent with the length direction of the workbench 1 to ensure its stability during the movement.

[0051] One side of the two second guide rods 34 is respectively fixedly connected with the corresponding first clamping plate 14. In this way, when the first clamping plate 14 moves, the second guide rods 34 will be driven to slide on the fixing strip 33.

[0052] A tension spring 35 is sleeved on the outer wall of each second guide rod 34. The two ends of the tension spring 35 are respectively fixedly connected to the first clamping plate 14 and the side of the fixing bar 33 that is close to each other. When the moving frame 5 is away from the second clamping plate 15, that is, when no thrust is applied to the second clamping plate 15, the tension spring 35 will automatically return to its original state, thereby driving the first clamping plate 14 and the second clamping plate 15 to reset, thereby quickly releasing the clamped bracket.

[0053] In order to improve the stability and positioning accuracy of the glue gun barrel 13 on the mounting frame 12: a plurality of limiting blocks 30 are arranged inside the limiting cover 26, and a positioning groove 31 corresponding to the limiting block 30 is provided at the bottom end of the glue gun barrel 13. When the glue gun barrel 13 is inserted into the limiting cover 26, the positioning groove 31 will fit with the limiting block 30, thereby realizing accurate positioning of the glue gun barrel 13.

[0054] In the present application, when in use, the device is powered on, and the cover plate is placed on the material platform 3, and then the material platform 3 is pushed into the rectangular opening 2, and the universal wheel 4 below is locked, and then the bracket is placed between the two second clamping plates 15 and the two first clamping plates 14;

[0055] Then put the structural glue in the glue gun barrel 13, and insert the glue gun barrel 13 into the mounting hole 23 until the bottom of the glue gun barrel 13 hits the limit cover 26, at this time the stop plate 32 is located in the glue gun barrel 13, and finally fix the fixing plate 24 on the mounting frame 12 by bolts;

[0056] Then the electric push rod 7 extends, and in the process of extending, it can drive the connecting frame 8 to move downward until the suction cup under the connecting frame 8 contacts the topmost cover plate, and the suction cup is started to adsorb the top cover plate, and after the adsorption is completed, the electric push rod 7 is started to retract and drive the connecting frame 8 to move upward;

[0057] Secondly, the motor 10 is started to drive the first screw 11 to rotate. The rotation of the first screw 11 can drive the moving frame 5 to move. The movement of the moving frame 5 can drive the connecting frame 8 to move toward the first clamping plate 14, and at the same time can drive the connecting column 20 to move in the waist-shaped hole 37. During the movement, the rack 22 can be driven to move through the connecting plate 21. The movement of the rack 22 can drive the gear 29 to rotate. The rotation of the gear 29 can drive the sliding ring 28 to rotate. The rotation of the sliding ring 28 can drive the second screw 27 to rotate. The second screw 27 can move upward in the limit cover 26, drive the abutment plate 32 to move upward, and the structural adhesive can be squeezed out of the glue gun barrel 13. At the same time, the connecting frame 8 drives the cover plate to move, and glue is applied while moving;

[0058] Continue to start the motor 10 to drive the moving frame 5 to move, and drive the connecting frame 8 to move to the top of the bracket. During the movement of the moving frame 5, the corresponding second clamping plate 15 can be driven to move inwards through the protrusion 19. The movement of the second clamping plate 15 can drive the first clamping plates 14 on both sides to approach each other to clamp the bracket through the two connecting rods 36. When the two first clamping plates 14 are close to each other, the other second clamping plate 15 can be driven to move inwards through the connecting rod 36 to achieve the front, back, left and right positioning of the bracket.

[0059] After moving into position, start the electric push rod 7 to extend and drive the connecting frame 8 to move downward to place the cover on the bracket, and continue to start the electric push rod 7 to drive the connecting frame 8 to move downward to press the cover. After the pressing is completed, start the electric push rod 7 to drive the connecting frame 8 to reset and move, and start the motor 10 to drive the moving frame 5 to reset and move. During the reset process of the moving frame 5, the rack 22 drives the gear 29 to rotate in the opposite direction. Due to the effect of the one-way bearing, the sliding ring 28 will not be driven to rotate, and the processing is continued in sequence.

[0060] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 10 and the electric push rod 7 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
