DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0019] See attached Figures 1 to 10 As shown, a table tennis racket board pasting machine in this embodiment includes a working platform 1 and a conveyor line 2 and a conveyor line 3 arranged in a cross shape; a pressing plate platform 4 is arranged at the intersection and overlap of the conveyor line 2 and the conveyor line 3, and the plates or rubber plates transported on the conveyor line 2 and the conveyor line 3 are stacked on the pressing plate platform 4 in the order of table tennis racket pasting plates, and are pressed, adhered and compounded on the pressing plate platform 4 to form a finished composite table tennis racket plate.

[0020] The two ends of the conveyor line 2 3 along its length direction are respectively provided with a finished product unloading mechanism 7 and a rubber plate empty plate loading mechanism 8 for loading empty rubber plates. The finished product unloading mechanism 7 is used to automatically transport the composite-formed table tennis racket plate to the next processing station, and the rubber plate empty plate loading mechanism 8 is used to automatically transfer the empty rubber plate to the double-sided gluing mechanism 9 for double-sided gluing treatment, so that the upper and lower surfaces of the subsequent rubber plate can be fixedly bonded with the thick plate and the thin plate; In some embodiments, the finished product unloading mechanism 7 can be a conveyor belt structure composed of a motor, gears and belts, or it can be other known transportation mechanical structures that can transport the product to the next workstation, which will not be elaborated here.

[0021] The empty rubber sheet feeding mechanism 8 includes an empty rubber sheet feeding support 82 and an empty rubber sheet feeding module 81 horizontally arranged thereon, and the straight line where the length direction of the empty rubber sheet feeding module 81 is located is perpendicular to the straight line where the length direction of the horizontal moving module 52 is located. A lifting cylinder is vertically arranged on the empty rubber sheet feeding module 81, and a vacuum suction plate 55 for sucking the empty rubber sheet is horizontally arranged at the top of the piston rod of the lifting cylinder. It is convenient to automatically feed the empty rubber sheet to the double-sided gluing mechanism 9.

[0022] A double-sided gluing mechanism 9 for gluing the empty surface of the rubber sheet is arranged between the pressing plate platform 4 and the empty rubber sheet feeding mechanism 8, so that the empty rubber sheet becomes a rubber sheet with glue coated on both sides. A thin plate or a thick plate can be alternately bonded to the upper and lower surfaces of each rubber sheet, so that multiple layers of plates can be bonded and compounded into the required composite table tennis racket plate.

[0023] The conveyor line 1 2 is provided with a plate feeding mechanism 5 along its length direction, and the plate feeding mechanism 5 includes at least one set of three-axis driving mechanisms and a conveying mechanism connected thereto, so as to cross-transport thick and thin plates to the pressing plate platform 4, and press and adhere them to the upper and lower surfaces of the glued plates. The plate feeding mechanism 5 can sequentially feed thin plates and thick plates respectively, and transport the thin plates and thick plates to the designated plate compounding station through the conveying mechanism.

[0024] Specifically, when the board bonding machine is working, the above-mentioned boards and rubber boards are stacked from bottom to top in the order of thin board, rubber board, thick board, rubber board, and thin board, so that each rubber board is bonded to a thin board or thick board on both the upper and lower sides, thereby ensuring that the five-layer board is bonded together to form a stable composite table tennis racket board. The composite table tennis racket board bonded in this way has a longer service life. And the entire process of feeding and bonding the board and the rubber board is an automated operation, and there is no need for the staff to bond the boards to the rubber board one by one. While effectively improving the efficiency of board bonding for table tennis rackets, it also reduces the labor intensity of the staff and the processing cost of the enterprise.

[0025] The plate feeding mechanism 5 also includes a feeding support frame 51 mounted on the pressing plate platform 4. The three-axis driving mechanism is connected to the feeding support frame 51 through a horizontal moving module 52. The horizontal moving module 52 can drive the three-axis driving mechanism to move back and forth along the length direction of the feeding support frame 51, so as to automatically transfer the thin plate or thick plate located on the conveying mechanism from the loading position to the pressing plate platform 4, thereby realizing automatic material transfer of the thin plate or thick plate.

[0026] The three-axis driving mechanism includes a lifting driving member 53 vertically arranged on the horizontal moving module 52 and a rotating driving member 54 located at the driving end of the lifting driving member 53. The transporting mechanism is located at the rotating shaft end of the rotating driving member 54 and is a vacuum suction plate 55. The driving of the lifting driving member 53 can make the transporting mechanism move up and down, thereby adjusting the height position of the plate transported by the transporting mechanism to make it more accurately placed. At the same time, after the plate is placed, downward pressure is applied to the plate from top to bottom, so that the adhesion between the plate and the rubber plate is more stable.

[0027] The rotary drive member 54 can drive the vacuum suction plate 55 to rotate the angle after adsorbing the thick plate or thin plate, so as to avoid position deviation between the plate and the rubber plate placed below when the plate is placed later, causing the table tennis racket to be misaligned and affecting its processing efficiency.

[0028] It should be noted that the lifting drive component 53 can be a lifting cylinder or a lifting module, as long as it is a known mechanical structure that can meet the requirements of up and down lifting and height adjustment; the rotating drive component 54 is a rotating drive motor or a dividing plate, as long as it is a known mechanical structure that can achieve angle adjustment.

[0029] In addition, the plates are uniformly made of thin plates and thick plates that can be bent along their length, and the rubber plates are made of rubber plates that can be bent along their width. The setting of the rotating drive member 54 can also ensure that the bending stress of each plate and the rubber plate is always perpendicular to each other after stacking, thereby further improving the service life of the table tennis racket.

[0030] It should be noted that the bending directions of the plate and the rubber sheet are not limited, as long as the bending directions are perpendicular to each other when the two are stacked.

[0031] An automatic lifting hopper mechanism 6 for cyclically feeding thin plates or thick plates is respectively arranged at both ends of the conveyor line 2 in the length direction, and the automatic lifting hopper mechanism 6 corresponds to the position of the transport mechanism. Each automatic lifting hopper mechanism 6 corresponds to the automatic cyclic feeding of thin plates or thick plates, and does not require staff to feed the materials, which can improve the feeding efficiency of thick plates and thin plates, and the automatic lifting hopper mechanism 6 corresponds to the position of the transport mechanism, which is convenient for the vacuum suction plate 55 to suck the materials.

[0032] In some embodiments, two sets of three-axis driving mechanisms are arranged on the loading support frame 51, and the two sets of three-axis driving mechanisms correspond to the positions of an automatic lifting hopper mechanism 6 respectively, so as to realize the rapid loading of thin plates and thick plates.

[0033] See attached Figures 1 to 2When pasting the board, the thin board is loaded first. Therefore, the horizontal moving module 52 is turned on, driving the three-axis driving mechanism on the left to move to the top of the automatic lifting hopper mechanism 6 on the left, and the lifting driving member 53 drives the rotating driving member 54 to move downward, so that the vacuum suction plate 55 adsorbs the thin board on the automatic lifting hopper. After the adsorption is completed, the horizontal moving module 52 continues to work, driving the thin board to move above the pressing plate platform 4, and the rotating driving member 54 drives the vacuum suction plate 55 to rotate to adjust the position of the thin board, and after the position adjustment is completed, it is placed on the pressing plate platform 4 with the assistance of the lifting driving member 53. At the same time, the vacant three-axis driving mechanism on the right is driven by the horizontal moving module 52 to move to the top of the automatic lifting hopper mechanism 6 on the right, and absorbs the thick board thereon to realize the thick board material removal.

[0034] That is, at least one vacuum suction plate 55 in the two three-axis driving mechanisms is in a state of having material, thereby improving the efficiency of the table tennis racket sticking to the board.

[0035] It should be noted that a pair of automatic lifting hopper mechanisms 6 for automatically loading empty rubber sheets are also provided on the side of the empty rubber sheet loading mechanism 8 .

[0036] The automatic lifting hopper mechanism 6 includes a hopper mounting frame 61, a hopper 64, a circulating drive assembly 63 and a sensing assembly 65. The hopper mounting frame 61 is provided with a circular circulating track 62 along its height direction. In some embodiments, the material taking place of thin plates or thick plates is arranged at the top of the circulating track 62, which is convenient for taking materials into the hopper, and there will be no interference in the vertical direction when taking materials. The setting of the circulating track 62 enables the track to drive multiple hoppers to move synchronously during the rotation process. When the thin plates or thick plates in the hopper at the top of the circulating track 62 are completely taken, the circulating track 62 rotates, so that the hopper at the second height and filled with thin plates or thick plates moves upward to the top of the circulating track 62 at this moment, and the thin plates or thick plates in the hopper can continue to be taken, thereby realizing uninterrupted cyclic feeding of thin plates or thick plates, and effectively improving the feeding speed of thin plates or thick plates. At the same time, after the above rotation, the hopper at the bottom of the circulating track 62 can also be filled with thin plates or thick plates.

[0037] In addition, the hopper may be damaged after long-term use, and the detachable arrangement of the hopper and the circulation track 62 also facilitates its replacement at any time.

[0038] When the hoppers are arranged in sequence, a distance is left between two adjacent hoppers to avoid interference with the subsequent sensors in sensing whether there are thin plates or thick plates in the current hopper.

[0039] The multiple hoppers are detachably arranged in sequence on the outer periphery of the circulating track 62, and the circulating drive assembly 63 includes a rotating drive machine 631, a driving gear 632 and a driven gear 633. The circulating track 62 is wound around the outer periphery of the driving gear 632 and the driven gear 633 and meshed with them, so that the multiple hoppers can rise or fall relative to the hopper mounting frame 61; when the rotating drive machine 631 drives the driving gear 632 to rotate, it can drive the circulating track 62 meshed with it to rotate, thereby providing power for the rising or falling of the hoppers thereon.

[0040] The rotary drive motor 631 can drive the circulating track 62 to rotate so that multiple hoppers rise or fall relative to the hopper mounting frame 61. The sensing component 65 is installed on the hopper mounting frame 61 and includes a sensor. The sensor corresponds to the position of the hopper at the thick plate or thin plate material collection point to sense whether there is material in the hopper at the material collection point.

[0041] Specifically, the sensor corresponds to the empty rubber sheet position at the bottom of the hopper at the thick or thin plate material taking place, and can sense whether there is a thick or thin plate placed within the height range of this point, so as to judge whether there is still a thick or thin plate in the hopper and whether the next hopper needs to be replaced. That is, through the induction of the sensor, the cooperation of the circulating track 62 and the circulating drive assembly 63, it can sense whether there is a thick or thin plate in the hopper, and realize the automatic loading of the table tennis racket board, thereby improving the loading efficiency of the thick or thin plates.

[0042] Specifically, the sensor is electrically connected to the rotary drive motor 631. When the sensor senses that there is no thick plate or thin plate at the height it is set to, it will transmit a signal to the rotary drive motor. At this time, the rotary drive motor starts to work, driving the active gear 632 to rotate, and the circulating track 62 can drive the hopper filled with thick plates or thin plates to move up one carrier position. When the sensor senses that there is a thick plate or thin plate in the hopper, it will remind the plate feeding mechanism 5 to automatically grab the thick plate or thin plate in the hopper. At the same time, the raw material hopper will drop one carrier position under the rotation of the rotary track.

[0043] It should be noted that the type of the sensor is not limited, and it can be a sensor as long as it can sense whether there are empty rubber sheets at the bottom of the hopper.

[0044] There are two groups of sensing components 65, and they are symmetrically arranged along the center line of the length direction of the hopper mounting frame 61. The sensing component 65 also includes a sensor mounting frame 651. The sensor mounting frame 651 is arranged on the outside of the hopper mounting frame 61, and the straight line in its length direction is parallel to the straight line in the width direction of the hopper mounting frame 61. A plurality of sensor mounting holes 652 for installing sensors are opened on one side of the sensor mounting frame 651 close to the feeding end.

[0045] The circulating track 62 is a circulating chain, and each hopper is connected to a single chain plate on the circulating chain through a connector. A plurality of hoppers can be assembled to the circulating chain in sequence through the connector.

[0046] The connecting piece is set in a shape, one side of which is fixedly connected to the chain plate, and the other side is provided with at least one connecting hole, through which the locking screw passes and is connected to the hopper. The hopper and the circulating chain are locked and connected by screws, which facilitates the disassembly and replacement of the hopper and makes the operation more convenient.

[0047] There are two groups of induction components 65, which are symmetrically arranged along the center line of the length direction of the hopper mounting frame 61. The induction components 65 also include an induction mounting frame 651, which is arranged on the outside of the hopper mounting frame 61, and the straight line in its length direction is parallel to the straight line in the width direction of the hopper mounting frame 61. A plurality of induction mounting holes 652 for mounting the induction components are provided on the side of the induction mounting frame 651 close to the feeding end. The induction components can be through-beam sensors. When there is no plate in the hopper, the through-beam sensor on one side can receive the signal of the through-beam sensor on the other side, and the signal is then transmitted to the circulation drive component 63, and the circulation drive component 63 starts to work to drive the circulation track 62 to rotate, so as to realize the automatic rise of the hopper below by one carrier station and automatic loading of materials; after the hopper below the raw material hopper, which is full of plates, moves up by one station, the plates at the bottom of the hopper will block the signals between the two through-beam sensors, and the through-beam sensor will transmit the signal of blocking the material to the material taking process, reminding it to continue taking the materials. This enables uninterrupted automatic loading of the plates.

[0048] The hopper includes a connecting plate, a supporting plate vertically arranged at the bottom thereof, and a limit baffle. The connecting plate is connected to a circulating track 62. The two limit baffles are respectively arranged at both ends of the supporting plate in the length direction. The limit baffles extend in the width direction of the supporting plate.

[0049] The connecting plate, the supporting plate and the limit baffle are integrally formed. The supporting plate is used to support and place multiple plates, and the limit baffle can prevent the plates in the hopper from falling during the rising process, thereby ensuring the transportation efficiency of the plates.

[0050] The installation position of the sensor installation hole 652 matches the position of the support plate, and the limit baffle is set shorter than the width of the support plate, which can avoid the limit baffle from interfering with the induction of the sensor and avoid signal reception errors.

[0051] Two circulating tracks 62 are provided, and the two circulating tracks 62 are respectively provided inside the hopper mounting frame 61, and are symmetrically provided along the center line of the length direction of the hopper mounting frame 61. By providing two circulating tracks 62, the hopper is more stable during the conveying process, and the plate is prevented from falling from the hopper due to the tilting phenomenon on one side of the length direction.

[0052] The driving gear 632 and the driven gear 633 on the two circulating tracks 62 are connected by a transmission shaft, and the rotary drive machine 631 is arranged on the hopper mounting frame 611 and connected to the transmission shaft that passes through the driving gear 632. The two circulating tracks 62 are driven by the transmission shaft, so that only one rotary drive machine 631 is needed to realize the synchronous rotation of the two circulating tracks 62.

[0053] In some embodiments, the rotary drive machine 631 may be a speed reducer or a drive motor, and is not limited to the above two types. Any known mechanical structure that can realize transmission of the transmission shaft may be used.

[0054] A guide member is provided on the hopper mounting frame 61 at a position corresponding to the circulating track 62 , and two parallel chain guide grooves are respectively provided on both sides of the guide member in the length direction and along the height direction thereof.

[0055] The chain plates on both sides of each circulating chain are located in a corresponding chain guide groove, and the chain guide groove provides guidance for the circulating rotation of the circulating chain to ensure the stability of multiple hoppers thereon during the circulating rotation process.

[0056] A rubber sheet empty board pushing platform 10 is provided between the rubber sheet empty board feeding mechanism 8 and the double-sided gluing mechanism 9, and a pushing cylinder 103 is horizontally provided on the rubber sheet empty board pushing platform 10, and a pushing plate 102 for pushing the rubber sheet empty board on the rubber sheet empty board pushing platform 10 to the double-sided gluing mechanism 9 is connected to the top of the piston rod of the pushing cylinder 103. After the rubber sheet empty board feeding mechanism 8 takes the material, the rubber sheet empty board is directly placed on the rubber sheet empty board pushing platform 10, and the pushing cylinder 103 drives the pushing plate 102 to move toward the double-sided gluing mechanism 9, so that the rubber sheet empty board can be pushed into the double-sided gluing mechanism 9, and double-sided gluing is automatically performed.

[0057] In some embodiments, a pushing cylinder 103 is disposed on the lower surface of the rubber sheet empty plate pushing platform 10, and its telescopic end faces in a direction away from the double-sided gluing mechanism 9. An end of the rubber sheet empty plate pushing platform 10 away from the double-sided gluing mechanism 9 is provided with a distance limiting groove 101 for the pushing plate 102 to move in a direction toward or away from the double-sided gluing mechanism 9.

[0058] Specifically, the push plate 102 is arranged in a U-shaped structure.

[0059] The double-sided gluing mechanism 9 includes a gluing support 94, on which an upper gluing roller 92 and a lower gluing roller 93 are sequentially arranged from top to bottom. A guide roller 91 is correspondingly arranged on one side of the upper gluing roller 92 and the lower gluing roller 93 close to the blank rubber sheet feeding mechanism 8, and the lower part of the lower gluing roller 93 is immersed in a glue storage box 95 located below it. When gluing, the lower gluing roller 93 contacts the upper gluing roller 92, and when the lower gluing roller 93 rotates to glue, the surface of the upper gluing roller 92 can also be evenly covered with glue. When the blank rubber sheet passes between the upper gluing roller 92 and the lower gluing roller 93, the upper and lower surfaces of the blank rubber sheet can be glued by the upper gluing roller 92 and the lower gluing roller 93 to form the rubber sheet required for subsequent board pasting.

[0060] In some embodiments, a rubber roller driving motor is also provided, and the driving end of the rubber roller driving motor is connected to one end of the lower rubber roller 93 to drive the lower rubber roller 93 to rotate and glue. A moving guide groove is provided on the glue coating bracket 94 for the upper glue coating roller 92 to move up and down, and the two ends of the upper glue coating roller 92 in the length direction are respectively connected to the moving block through a bearing, and one end of the locking bolt passes through the top of the glue coating bracket 94 and is fixedly connected to the moving block. A spring is sleeved on the part of the locking bolt located in the moving guide groove. Under the action of the spring, a downward force can be applied to the upper glue coating roller 92 until it abuts against the lower glue coating roller 93, which is convenient for the initial state. The lower glue coating roller 93 initially applies glue to the upper glue coating roller 92, and at the same time, the elastic force of the spring can also apply a pre-tightening force to the upper glue coating roller 92, so that when the lower glue coating roller 93 rotates to apply glue, it can also drive the glue plate coated with glue to move toward the direction close to the pressing plate platform 4 for loading.

[0061] A rubber sheet loading mechanism 12 is arranged above the pressing plate platform 4, and the rubber sheet loading mechanism 12 includes a rubber sheet loading module 121 arranged along the length direction of the conveyor line 23, a fixed support 122 located thereon, and a clamping cylinder 123. The clamping cylinder 123 is located on the fixed support 122 on the side facing the double-sided gluing mechanism 9. The rubber sheet loading module 121 drives the fixed support frame to move toward the double-sided gluing mechanism 9 so that the clamping cylinder 123 clamps one end of the rubber sheet coated with glue.

[0062] In some embodiments, the fixed support member 122 is horizontally arranged in a direction perpendicular to the rubber sheet loading module 121. When taking the rubber sheet, the rubber sheet loading module 121 drives the fixed support member 122 to move toward the direction close to the double-sided gluing mechanism 9 until the clamping cylinder 123 thereon clamps the rubber sheet coated with glue. Then the rubber sheet loading module 121 drives the fixed support member 122 to move toward the direction away from the double-sided glue coating mechanism to above the pressing plate platform 4. The clamping cylinder 123 is released, and the rubber sheet can fall onto the pressing plate platform 4, realizing automatic loading of the rubber sheet.

[0063] An inclined rubber sheet blanking plate 11 is provided between the double-sided gluing mechanism 9 and the pressing plate platform 4. The rubber sheet blanking plate 11 corresponds to the position of the clamping cylinder 123. A pushing cylinder 124 is vertically provided on both sides of the fixed support 122 along its length direction. A vertical pushing rod 125 is connected to the top of the piston rod of each pushing cylinder 124.

[0064] Two pushing grooves 44 for the pushing rod 125 to insert and move and at least one liftable limit block 43 are symmetrically arranged on the pressure plate platform 4, and the pushing groove 44 is opened along the length direction of the conveyor line 23. A front baffle plate 41 is arranged on the side of the pressure plate platform 4 away from the double-sided gluing mechanism 9, and a limit cylinder 42 is vertically arranged on the back of the front baffle plate 41. The limit block 43 is at the top of the piston rod of the limit cylinder 42, and a clearance groove for the limit block 43 to be inserted is opened on the pressure plate platform 4.

[0065] After the upper and lower surfaces of the rubber sheet are coated with glue, the rubber sheet blank slides to the rubber sheet entrance on the pressing plate platform 4 through the inclined rubber sheet unloading plate 11 to wait for the clamping claw cylinder 123 to clamp and take the material. When the sheet is loaded under the action of the sheet loading mechanism 5, the rubber sheet loading module 121 drives the clamping claw cylinder 123 to move toward the rubber sheet until the clamping claw cylinder 123 can clamp one side of the rubber sheet. Then, the rubber sheet feeding module 121 drives the clamping claw cylinder 123 holding the rubber sheet to move toward the direction of the pressing plate platform 4. At this time, the piston rod of the limit cylinder 42 is in an extended state. When the side of the rubber sheet clamped by the clamping claw cylinder 123 abuts against the limit stopper 43, the surface rubber sheet moves into place. At this time, the clamping claw cylinder 123 is released, so that the rubber sheet can fall accurately onto the substrate below. The rubber sheet feeding module 121 drives the fixed support 122 to reset. After the multi-layer board material and the rubber board are pressed and bonded to form the finished table tennis racket board material, the piston rod of the second pushing cylinder 124 is extended to allow the pushing rod 125 to be inserted into the pushing groove 44, and the piston rod of the limit cylinder 42 is retracted to allow the limit block 43 to move to the bottom of the pressure plate platform 4. At this time, the rubber board loading module 121 drives the pushing rod 125 to move toward the direction of the finished product unloading mechanism 7, so that the table tennis racket board material with layer by layer of boarding can be smoothly pushed out to the finished product unloading mechanism 7 for automatic unloading.

[0066] It should be noted that the length of the push groove 44 is greater than the length of the rubber sheet so that there will be no interference between the insertion of the push rod 125 and the rubber sheet; the distance between the two push rods 125 is less than the width of the rubber sheet to ensure that the two push rods 125 can smoothly push the rubber sheet to the finished product unloading mechanism 7 for automatic unloading.

[0067] In some embodiments, a material unloading baffle 111 is provided on the top of one end of the rubber sheet unloading plate 11 close to the pressure plate platform 4, and a baffle assembly 13 is provided above the rubber sheet unloading plate 11. The baffle assembly 13 includes two symmetrically arranged connecting baffles 131, one end of the two connecting baffles 131 is respectively hinged to the connecting rod at the top of the glue coating bracket 94, so that the connecting baffles 131 can rotate around the connecting rod; the other end is respectively connected to a baffle wheel 134 by a bearing, and the two baffle wheels 134 are connected by a connecting rod. When the rubber sheet coated with glue on both sides enters the rubber sheet unloading plate 11 and slides down along it, one end of it will contact and push up the baffle wheel 134 before the baffle wheel 134, and pass through between the baffle wheel 134 and the rubber sheet unloading plate 11. The setting of the baffle wheel 134 can effectively prevent the rubber sheet from sliding down too fast and flying out of the rubber sheet unloading plate 11, thereby ensuring the loading efficiency of the rubber sheet.

[0068] In addition, in order to ensure the stability of the baffle assembly 13 during use, the middle parts of the two connecting baffles 131 are also connected by a stabilizing connecting plate 132 .

[0069] A table tennis racket board attachment method comprises the following steps: S1: Apply glue to the upper and lower surfaces of the empty plastic sheet; S2: The sheet feeding mechanism 5 and the rubber sheet feeding mechanism 12 sequentially stack the thin sheet, the thick sheet and the rubber sheet on the pressing plate platform 4 in the order of thin sheet, rubber sheet, thick sheet, rubber sheet and thin sheet, and press and adhere them; S3: The finished table tennis racket board is formed and automatically unloaded.
