Description

Technical Field

[0001] The invention relates to a glue dispensing device, in particular to a glue dispensing device for edge strips of a pickleball racket. Background Art

[0002] A pickleball racket is similar to a table tennis racket, but unlike a table tennis racket, the racket head is rectangular in shape. Pickleball rackets are typically between 10 and 16 mm thick. Racks of different thicknesses each have their own characteristics and are suitable for different groups of players: 13mm Thickness: Racks of this thickness are lighter and have faster swing speeds, making them suitable for quick reactions and agile play, but they have poor shock absorption and may feel harder when hitting the ball. 14mm Thickness: This thickness strikes a balance between weight and shock absorption, suitable for most players, providing better hitting accuracy and comfort. 16mm Thickness: Thicker rackets provide better shock absorption and a more comfortable feel, making them suitable for power-based play, but they may have slower swing speeds.

[0003] The production process of a pickle ball racket is as follows: first, a cutting machine cuts the material (glass fiber, carbon fiber, etc.) into the shape of a pickle ball racket, then a printing machine prints patterns on the front and back of the racket, and then the side strips are wrapped around the racket and glued and fixed; the side strips are long rubber strips with a U-shaped structure, and glue is dispensed at the corner between the bottom and side surfaces of the side strips through a glue dispenser, and then the side strips are wrapped around the circumference of the racket, and fixed with support until the glue solidifies to achieve the fixation of the side strips.

[0004] When the glue dispensing machine dispenses glue on the edge strips, the edge strips need to be fixed. There are currently two ways to fix the edge strips. The first is to set a fixed rod and a parallel movable rod. The movable rod is controlled by a cylinder. The cylinder pushes the movable rod to move close to the fixed rod to clamp and fix the edge strip between the fixed rod and the movable rod; then the glue dispensing machine dispenses glue; the second is to open several long grooves on a flat plate. When dispensing glue, the edge strips are placed in each long groove, and then the glue dispensing machine works to dispense glue; the first edge strip fixing method is less efficient and can only fix one edge strip at a time. The second edge strip fixing method can only fix edge strips of one width and cannot adapt to the fixation of edge strips of various widths. Each time the edge strips of different widths are replaced, the entire flat plate needs to be replaced, which is more troublesome to operate and has low production efficiency, while increasing the equipment manufacturing cost.

The slider 12 moves to the right, driving the moving rod 3 to move to the right, and then the edge strip 5 that has been glued can be removed; and then the next glue dispensing can be carried out.

[0031] When the output end of the hydraulic telescopic rod 22 in the above scheme is extended, since the slide plate 35 moves to the left faster than the driving rod 15 moves upward, the L plate 39 will move to the limited position earlier than the driving rod 15 and wait for the driving rod 15 to drive the pin 41 to move upward and insert into the socket 40 of the L plate 39; the thrust block 37 moves to the left to drive the two docking blocks 29 to move away from each other to the maximum stroke, which just makes the first connecting rod 23 and the second connecting rod 24 move to the position limited by the corresponding slider 12, that is, the L plate 39 stops waiting for the pin 41 to move upward and insert into the socket 40 of the L plate 39. At this time, if the thrust block 37 continues to move to the left, it will not be able to drive the two docking blocks 29 to move away from each other. This limitation of the thrust block 37 can be achieved by designing the width of the thrust block 37 in the front and rear directions.

[0032] During production, after the edge strip 5 is clamped and fixed, since the material of the edge strip 5 is rubber, the edge strip 5 becomes uneven and needs to be manually pressed to make the edge strip 5 flat. In order to solve this problem, in this embodiment, the upper end face of the fixing rod 2 is hinged with a pressure plate 42, and a torsion spring 44 is provided on the hinge axis of the pressure plate 42. The torsion spring 44 always drives the pressure plate 42 to rotate ninety degrees clockwise, so that the bottom surface 50 of the pressure plate 42 presses the middle position of the bottom of the edge strip 5, so that the edge strip 5 remains flat, and then the moving device 7 controls the movement of the hose 9 and the needle to dispense glue on the corners of the bottom of the edge strip 5.

[0033] In the above scheme, each time the side strip 5 is placed between the fixed rod 2 and the movable rod 3, it is necessary to manually rotate the pressure plate 42 so that the pressure plate 42 is rotated ninety degrees counterclockwise, and then the side strip 5 is placed, and then the pressure plate 42 is released to press the side strip 5. Manual operation is relatively troublesome. In order to solve this problem, in this embodiment, both ends of the left side of the pressure plate 42 are fixedly provided with hinged rods 45, and the outer end of the hinged rod 45 is fixedly provided with a hinge shaft. The hinge shaft is located in the accommodating groove 46 opened on the upper end surface of the fixed rod 2 and is rotatably connected to the fixed rod 2. The torsion spring 44 is sleeved on the hinge shaft, one end of the torsion spring 44 is connected to the fixed rod 2, and the other end of the torsion spring 44 is connected to the hinge shaft. The torsion spring 44 always drives the pressure plate through the hinge shaft and the hinge rod 45 in turn. 42 rotates ninety degrees clockwise; the upper end surfaces of the first connecting rod 23 and the second connecting rod 24 are fixedly provided with a connecting body 47, and the inner end of the connecting body 47 is fixedly provided with a limiting block 48, and the lower end surface of the limiting block 48 and the fixed rod 2 are slidably arranged along the left and right directions; a ninety-degree arc groove 49 is provided on the outer side surface of the limiting block 48, and the bottom surface 50 of the ninety-degree arc groove 49 gradually tilts away from the outer side surface of the limiting block 48 from top to bottom, and a through hole 51 connected to the ninety-degree arc groove 49 is provided on the inner side surface of the limiting block 48; a guide rod 52 is fixedly provided on the side surface of the hinged rod 45, and the free end of the guide rod 52 is located in the ninety-degree arc groove 49, and the free end of the guide rod 52 is in contact with the bottom surface 50 of the ninety-degree arc groove 49.

[0034] During use, after the glue dispensing is completed and the side strip 5 needs to be removed, the output end of the hydraulic telescopic rod 22 extends, producing two effects: a, driving the first connecting rod 23 and the second connecting rod 24 to move away from each other, thereby driving the rear positioning block 4 and the front positioning block 4 to move away from each other; b, the driving rod 15 moves upward, driving the driving block 16 to move upward, so that the return spring 14 pushes the slider 12 to move to the right, and the slider 12 drives the moving rod 3 to move to the right; and then the side strip 5 can be taken out. When the first connecting rod 23 and the second connecting rod 24 move away from each other, the limit block 48 is driven by the connecting body 47 to move toward the end directions of the front and rear ends of the fixed rod 2, and the limit block 48 moves through the bottom surface 50 of the ninety-degree arc groove 49 to force the guide rod 52 to slide in the ninety-degree arc groove 49, so that the guide rod 52 drives the pressure plate 42 through the hinge rod 45 to overcome the force of the torsion spring 44 and rotate ninety degrees counterclockwise around the hinge axis. When the pressure plate 42 rotates to ninety degrees, the guide rod 52 passes through the through hole 51 of the limit block 48 and does not interfere with the continued movement of the limit block 48; at this time, the pressure plate 42 does not interfere with the insertion of the side strip 5 between the fixed rod 2 and the movable rod 3.

[0035] After the edge strip 5 is placed, the output end of the hydraulic telescopic rod 22 contracts, producing two effects: a. The latch 41 disengages downward from the socket 40 of the L plate 39, and the power spring 26 pushes the first connecting rod 23 and the second connecting rod 24 to move closer to each other, thereby driving the rear positioning block 4 and the front positioning block 4 to move similarly, clamping and positioning the two ends of the edge strip 5; b. The driving rod 15 moves downward, driving the driving block 16 to move downward, so that the driving block 16 pushes the slider 12 to move to the left, and the slider 12 drives the moving rod 3 to move to the left, clamping the edge strip 5. When the first connecting rod 23 and the second connecting rod 24 move toward each other, the limit block 48 is driven by the connecting body 47 to move toward the middle section of the fixed rod 2. The limit block 48 causes the bottom surface 50 of the 90-degree arc groove 49 to move away from the free end of the guide rod 52. The torsion spring 44 drives the hinge shaft to rotate clockwise, thereby driving the hinge rod 45 and the pressure plate 42 to rotate clockwise. The guide rod 52 on the hinge rod 45 slides in the 90-degree arc groove 49 until the bottom surface 50 of the pressure plate 42 presses against the bottom surface 50 of the edge strip 5. This achieves the purpose of eliminating the need for manual operation of the pressure plate 42.

[0036] In this embodiment, the first and second connecting rods 23 and 24 are provided with avoidance grooves 53 at positions corresponding to the hinge rod 45 . The avoidance grooves 53 are used to prevent the first and second connecting rods 23 and 24 from being interfered with when moving.

[0037] The working principle of the present invention is as follows: first, the edge strip 5 is placed between the fixed rod 2 and the mobile rod 3, and then the output end of the hydraulic telescopic rod 22 is contracted to make the latch 41 downwardly disengaged from the socket 40 of the L plate 39, and the power spring 26 pushes the first connecting rod 23 and the second connecting rod 24 to move closer to each other, thereby making the rear positioning block 4 and the front positioning block 4 move closer to each other, clamping and positioning the two ends of the edge strip 5, and then the output end of the hydraulic telescopic rod 22 is contracted and drives the mobile rod 3 to move leftward to clamp the side of the edge strip 5; at the first connecting rod, the second connecting rod 23 and the second connecting rod 24 are pushed closer to each other, thereby making the rear positioning block 4 and the front positioning block 4 move closer to each other, thereby clamping and positioning the two ends of the edge strip 5, and then the output end of the hydraulic telescopic rod 22 is contracted and drives the mobile rod 3 to move leftward to clamp the side of the edge strip 5; at the first connecting rod, the second connecting rod 23 and the second connecting rod 24 are pushed closer to each other, thereby clamping and positioning the two ends ... When the movable rod 23 and the second connecting rod 24 move toward each other, the connector 47 drives the stopper 48 toward the middle section of the fixed rod 2. The stopper 48 causes the bottom surface 50 of the 90-degree arc groove 49 to move away from the free end of the guide rod 52. The torsion spring 44 drives the hinge shaft to rotate clockwise, thereby driving the hinge rod 45 and the pressure plate 42 to rotate clockwise. The guide rod 52 on the hinge rod 45 slides within the 90-degree arc groove 49 until the bottom surface 50 of the pressure plate 42 presses against the bottom surface 50 of the edge strip 5, thereby flattening the bottom surface 50 of the edge strip 5. The movable device 7 then controls the rubber hose 9 and the needle to dispense glue to the edge strip 5. After the glue dispensing is completed, the output end of the hydraulic telescopic rod 22 extends, driving the moving rod 3 to move right to contact the clamping of the opposite edge strip 5, and at the same time driving the first connecting rod 23 and the second connecting rod 24 to move away from each other, so that the L plate 39 moves to the limited position and waits for the driving rod 15 to move upward to drive the latch 41 to move upward and insert into the socket 40 of the L plate 39. The movement of the first connecting rod 23 and the second connecting rod 24 away from each other drives the limit block 48 to move toward the end of the fixed rod 2. The limit block 48 moves through the bottom surface 50 of the 90-degree arc groove 49, forcing the guide rod 52 to slide in the 90-degree arc groove 49, thereby causing the guide rod 52 to drive the pressure plate 42 to overcome the force of the torsion spring 44 and rotate counterclockwise by 90 degrees through the hinge rod 45. When the pressure plate 42 rotates to 90 degrees, the guide rod 52 passes through the through hole 51 of the limit block 48 and does not interfere with the continued movement of the limit block 48; then the next glue dispensing cycle is carried out.
