Description

Technical Field

[0001] The utility model relates to the technical field of automatic glue dispensing machines, in particular to an automatic glue dispensing machine and a positioner thereof. Background Art

[0002] Automatic dispensing machine, also known as glue coating machine, glue dripping machine, glue spraying machine, glue filling machine, etc., is an automated machine that specializes in controlling fluids and dripping and applying fluids to the surface or inside of products. It can achieve three-dimensional and four-dimensional path dispensing, precise positioning, and precise glue control without drawing, leaking, or dripping. When using the automatic dispensing machine, a locator is required to position the product that needs to be dispensed.

[0003] However, existing positioners have poor product positioning effects. Most of them adopt a two-side fixing method and cannot perform multi-directional positioning of products according to their shapes and sizes. This can easily cause the products to shift during the dispensing process, and the anti-drifting effect is poor, which will directly affect the dispensing accuracy and directly increase the defective rate. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that the product cannot be positioned in multiple directions according to the shape and size of the product, which easily causes the product to be displaced and offset during the dispensing process and has poor anti-offset effect, and to propose an automatic dispensing machine and its positioner.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A positioner includes a placement plate arranged on an automatic dispensing machine, multiple groups of mounting frames are evenly slidably arranged on the placement plate, extension frames are symmetrically fixed on the side where the multiple groups of mounting frames are close to each other, and auxiliary components are arranged on the mounting frames and the placement plate.

[0007] The two cams are connected by a plurality of springs, each of which is connected to the bottom of the plate, and the two cams are connected by a plurality of springs.

[0008] Preferably, an annular slide is provided on the placement plate, and an arc-shaped slide is fixed to the bottom of each group of the mounting frames, and the arc-shaped slide is slidably arranged in the annular slide.

[0009] Preferably, an auxiliary plate for use with the mounting frame is rotatably mounted on the locking frame, and an elastic pad is embedded in the bottom of the auxiliary plate.

[0010] Preferably, the bottom of the limiting frame and the bottom of the placement tray are located on the same plane.

[0011] Preferably, the number of the mounting frames is at least five, and the extension frames are generally L-shaped.

[0012] An automatic glue dispensing machine includes the positioner described above.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The automatic dispensing machine and its positioner are designed with auxiliary components and multiple sets of slidable mounting plates so that the angle of the pressure plate can be freely adjusted according to the shape of the product. The design of the limit frame, locking bolt and locking nut can quickly form an extrusion locking structure to fix the adjusted mounting frame. The elastic rebound of the first spring can be used to quickly squeeze and position the product according to the size of the product. Under the elastic action of the second spring, the locking frame and the second teeth can be driven downward and the second teeth can be engaged in the gap between the first teeth. On the one hand, the extension plate and the pressure plate can be positioned to improve the fixing effect of the product and prevent the pressure plate from retracting due to external force. On the other hand, the downward pressure of the extension plate by the second teeth can be used to limit the pressure plate so that it can be tightly attached to the placement plate to prevent it from warping up and affecting the limiting effect. The pressure plate with self-adjustable position and locking structure can be used to position the product in multiple directions according to the shape and size of the product, which can effectively prevent the product from positional deviation during the dispensing process, improve the overall anti-drift effect of the positioner, and improve the dispensing accuracy.

[0020] 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.

[0021] Example

[0022] Reference Figures 1-4The cam 11 is a kind of cam 12 that is provided with the support frame 1 of the present invention, and the cam 12 is provided with the support frame 1 of the present invention. The first spring 8 is wound around the bottom of the bracket 12, and the two ends of the first spring 8 are fixed to the side where the mounting bracket 2 and the limit plate 6 are close to each other. A locking bracket 12 is inserted into the two adjacent groups of extension brackets 11. The number of mounting brackets 2 is at least five groups. The extension bracket 11 is an L-shaped structure as a whole. The limitation of the number of mounting brackets 2 improves the multi-directional positioning effect of the mounting bracket 2 on the product, and has more selectivity. The design of the extension bracket 11 with an L-shaped structure can increase the contact area with the locking bracket 12, thereby improving the stability of the locking bracket 12 when moving. The two ends of the bottom of each group of locking brackets 12 are fixed with second teeth 14 used in conjunction with the first teeth 10, and the second spring 13 is symmetrically wound around each group of locking brackets 12, and the two ends of the second spring 13 are fixed to the protruding end of the locking bracket 12 and the extension bracket 11. By utilizing the elastic rebound of the first spring 8, the product can be quickly squeezed and positioned according to the size of the product, and the extension plate 5 and the pressure plate 7 can be positioned under the elastic action of the second spring 13;

[0023] Reference Figure 1-Figure 3The locking frame 12 is rotatably equipped with an auxiliary plate 15 for use with the mounting frame 2, and an elastic pad is embedded in the bottom of the auxiliary plate 15. The design of the auxiliary plate 15 and the elastic pad allows the auxiliary plate 15 to be flipped over in time and brought into contact with the top of the mounting frame 2 when the second tooth 14 and the first tooth 10 are disengaged, thereby limiting the locking frame 12 to avoid affecting the normal expansion and contraction of the extension plate 5 and the pressure plate 7. The design of the elastic pad makes the auxiliary plate 15 more tightly connected to the mounting frame 2 or the top of the locking frame 12, and the bottom of the mounting frame 2 away from each other is fixed with a limiting frame 16 that fits on the placement tray 1, and the bottom of the limiting frame 16 is in contact with the placement tray The bottom of 1 is located in the same plane. The design of being located in the same plane prevents the limit frame 16 from colliding with the structure on the automatic dispensing machine when rotating. A locking nut 18 is fixed to the side of the limit frame 16 away from the placement plate 1. The locking nut 18 is internally threaded and connected to a locking bolt 17. One end of the locking bolt 17 passes through the limit frame 16 and fits on the placement plate 1. By setting an auxiliary component and adopting a pressure plate 7 that can adjust the position independently and has a locking structure, the product can be positioned in multiple directions according to the shape and size of the product, which can effectively prevent the product from positionally shifting during the dispensing process, thereby improving the overall anti-shifting effect of the locator and improving the dispensing accuracy.

[0024] An automatic glue dispensing machine includes the above-mentioned positioner.

[0025] In the present invention, the user selects the number of mounting brackets 2 required in advance according to the shape of the product, that is, if the product is square, four sets of mounting brackets 2 need to be selected, and the four sets of mounting brackets 2 are moved to the four sides of the placement tray 1, and the elastic rebound of the first spring 8 is used to push the pressure plate 7 to quickly contact the four sides of the product to press and position the product. Then the user rotates the locking bolt 17 to rotate and move it in the locking nut 18 until it contacts the placement tray 1, so that the extrusion force can be used to quickly fix the limit frame 16 on the placement tray 1, thereby limiting the position of the mounting bracket 2 and the pressure plate 7 to prevent rotation. Then the user rotates the auxiliary plate 15 to separate it from the mounting bracket 2 and rotate it to the locking frame 12. At this time, the user uses The elastic rebound of the second spring 13 can drive the locking frame 12 and the second tooth 14 to move downward quickly, and be clamped in the gap of the first tooth 10, so that the extension frame 11 and the pressure plate 7 can be quickly positioned, thereby improving the fixing effect of the product and preventing the pressure plate 7 from retracting due to external force. The second tooth 14 can be used to exert downward pressure on the extension plate 5 to limit the pressure plate 7 so that it can be tightly attached to the placement tray 1 to prevent it from warping and affecting the positioning effect. At this time, a pressure plate 7 that can adjust its position independently and has a locking structure is used. The product can be positioned in multiple directions according to its shape and size, which can effectively prevent the product from positional deviation during the dispensing process and improve the overall anti-drift effect of the locator. Then the automatic dispensing machine can start dispensing the product.

[0026] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
