Description

Technical Field

[0001] The present invention relates to the field of loading belt equipment, and in particular to an automatic loading belt equipment for plastic products and a method of using the same. Background Art

[0002] Due to their small size, small plastic products are often placed on carrier tape to facilitate subsequent processing and assembly. A carrier tape consists of two parts: a carrier body and a sealing tape. The carrier body has a dedicated slot for accommodating plastic products. The sealing tape is made of self-adhesive material that adheres tightly to the carrier body, effectively preventing the product from accidentally moving out of the slot.

[0003] However, existing loading belt systems have several operational shortcomings. Specifically, they can typically only load one product at a time, resulting in low loading efficiency. Furthermore, instability can easily occur during the loading process of the carrier belt and sealing tape, leading to unstable transport of the carrier belt and sealing tape.

[0016] The present invention also provides a method for using a plastic product automatic loading belt device, comprising the following steps:

[0017] 1. Plastic product sorting and transportation:

[0018] The plastic products are placed on the vibrating plate. Through the vibration, the plastic products are neatly arranged and transported forward along the conveyor track.

[0019] 2. Transfer device operation:

[0020] When the plastic product reaches the end of the conveyor track, the transfer device starts working; the stepper motor drives the swing arm to swing back and forth. The swing arm is linked with the drive rod through the waist groove, so that the Z-axis track and the T-frame on it move in the vertical direction.

[0021] At the same time, the suction cup rod moves left and right in the X-axis slide, coordinating with the up and down movement of the Z-axis track to ensure that the suction cup can accurately contact the plastic product on the conveyor track;

[0022] After the suction cup absorbs the plastic product, the stepper motor continues to drive, so that the suction cup and the plastic product move to the top of the track groove of the carrier body conveyor device;

[0023] During this process, the suction cup rod moves in the adjustment slide, and the spacing between the first longitudinal portion and the second longitudinal portion is adjusted to achieve equal spacing adjustment of the suction cups, ensuring that the plastic product can be accurately placed in the receiving groove in the carrier body;

[0024] 3. Carrier body transportation and positioning:

[0025] The carrier body is unwound from the carrier body raw material roll, passes through the avoidance hole and the second notch in sequence, and is transported to the track groove on the conveyor frame;

[0026] The active roller and the driven roller cooperate with the carrier body through the positioning protrusions on the side wall to achieve stable transportation of the carrier body;

[0027] A dual-axis motor drives the active roller to rotate, while the induction sheet rotates along with the other output shaft of the dual-axis motor. When the U-shaped photoelectric sensor detects the light-transmitting groove on the induction sheet, it sends a signal to the controller, which controls the dual-axis motor to stop, achieving periodic stopping of the carrier body, facilitating the precise placement of plastic products.

[0028] 4. Sealing tape conveying and pressing:

[0029] The sealing tape is unwound from the sealing tape roll, guided by several guide rollers, and enters the bottom of the baffle along the first notch;

[0030] When the carrier tape body and the sealing tape are in place, the cylinder of the pressing device drives the pressing block and the pressing strip to move downward. The pressing strip passes through the strip hole and presses the connection between the sealing tape and the carrier tape body to achieve pressing;

[0031] 5. Winding and finished product output:

[0032] The pressed carrier tape body and sealing tape continue to be transported forward and finally reach the winding device;

[0033] The winding motor rotates to drive the winding drum to rotate, and the strip loaded with plastic products is wound onto the winding drum;

[0034] The guide wheel is used to guide the conveying path of the strip to ensure that the strip can be wound smoothly on the reel;

[0035] 6. Press wheel positioning and spring buffer:

[0036] The pressure wheel uses the spring and connecting arm to stably position the carrier body, while avoiding the positioning protrusion to ensure smooth transportation of the carrier body;

[0037] The spring provides a certain buffering effect, which can reduce the vibration and deviation of the carrier body during transportation.

[0038] Compared with the related art, the present invention has the following beneficial effects: improving production efficiency:

[0039] The plastic products are neatly arranged on the vibration plate and transported to the designated position with the help of the conveyor track, thus realizing the automatic loading of plastic products.

[0040] The design of the transfer device enables plastic products to be transferred from the conveyor track to the carrier body quickly and accurately, greatly shortening the loading time.

[0041] The coordinated operation of the carrier tape conveyor and the sealing tape conveyor ensures the continuous loading of plastic products and the timely supply of sealing tape.

[0042] The automated operation of the laminating device and the winding device further improves production efficiency, making the entire belt loading process smoother and more efficient.

[0043] Guarantee product quality:

[0044] The carrier tape body conveying device and the sealing tape material conveying device convey relatively smoothly, thereby preventing the carrier tape body and the sealing tape material from wrinkling.

[0045] The precise coordination between the vibration plate and the conveyor track ensures the stability and accuracy of the plastic products during loading.

[0046] The suction cup of the transfer device can accurately pick up and place plastic products, avoiding damage or misalignment of the products during the transfer process.

[0047] The pressure strips of the pressing device can tightly press the sealing tape and the carrier tape body to ensure the firmness and sealing of the carrier tape. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0058] Please refer to Figures 1 to 8 An automatic loading belt device for plastic products mainly includes a body 1. A plurality of key components are carefully arranged on the top of the body 1 to ensure automatic and efficient loading of plastic products.

[0059] At the top of the machine body 1, the first thing that catches your eye is the vibrating plate 2, which neatly arranges the plastic products and conveys them to the conveyor track 6 at the output end. Next, the carrier conveyor 3 is cleverly mounted on the machine body 1. Its core component, the conveyor frame 7, features a track groove 8 at the top, specifically designed to accommodate the carrier body. To ensure accurate transfer of plastic products to the carrier body, a transfer device 9 is also installed on the top of the machine body 1.

[0060] The design of the transfer device 9 is particularly complex and sophisticated. It begins with a mounting plate 10 fixed to the top of the machine body 1, to which a horizontal plate 11 is further fixed. A vertical plate 12 extends from one end of the horizontal plate 11, and a Y-axis track 13 is securely mounted on one side of the vertical plate 12. A slider 14 slides freely on the Y-axis track 13, and a Z-axis track 15 is further mounted on the slider 14. The top of the Z-axis track 15 is connected to a connecting plate 16, to which a drive rod 17 is fixed. Furthermore, a stepper motor 18 is mounted on the side of the vertical plate 12 facing away from the Y-axis track 13. Its output shaft passes through the vertical plate 12 and is connected to a rocker arm 19. One end of the rocker arm 19 is cleverly designed with a waist-shaped groove 20, allowing the drive rod 17 to move flexibly within it. The vertical plate 12 also has a U-shaped groove 21, through which one end of the drive rod 17 is inserted.

[0061] The bottom end of the Z-axis track 15 is connected to a T-shaped frame 22, which is equipped with an X-axis slide 23, within which multiple suction cup rods 24 can be slidably connected. One end of these suction cup rods 24 passes through an adjustment slide 25 provided on the horizontal plate 11 and is fixedly connected to a suction cup 29 that can pick up and put down plastic products. The design of the adjustment slide 25 is very clever. It includes a first longitudinal portion 26 and a second longitudinal portion 27, and an inclined spacing adjustment portion 28 connecting the two. This design ensures that the spacing between adjacent first longitudinal portions 26 and second longitudinal portions 27 remains equal, thereby achieving equal spacing adjustment of the suction cups 29 by moving the suction cup rods 24 within the adjustment slide 25.

[0062] When the plastic product needs to be moved, the stepper motor 18 drives the rocker arm 19 to swing back and forth. This movement, through the linkage of the drive rod 17 and the connecting plate 16, enables the T-shaped frame 22 on the Z-axis track 15 to move up and down. Simultaneously, the suction cup rod 24 can also move left and right within the X-axis slot 23, ensuring that the suction cup 29 can accurately contact the plastic product on the conveyor track 6. Once the suction cup 29 has absorbed the plastic product, the stepper motor 18 is driven again, accurately transferring the plastic product from the conveyor track 6 to the carrier body within the track slot 8 of the carrier body conveyor device 3.

[0063] The design of the carrier body conveying device 3 is also very outstanding. It includes an active roller 30 and a driven roller 31 that are rotatably connected to the two ends of the conveying frame 7, and positioning protrusions 32 that cooperate with the carrier body are installed at equal angles on the side walls of both. A dual-axis motor 33 is also fixed on the conveying frame 7, and one of its output shafts is tightly connected to one end of the active roller 30. In order to ensure the stable transportation and periodic stopping of the carrier body, a U-shaped photoelectric sensor 34 is installed on the body 1, and cooperates with the induction plate 35 fixed on the other output shaft of the dual-axis motor 33. Light-transmitting grooves 36 are provided at equal angles on the induction plate 35. When the U-shaped photoelectric sensor 34 is facing the light-transmitting grooves 36, it can detect the signal and transmit the signal to the controller, thereby controlling the dual-axis motor 33 to stop working.

[0064] Furthermore, a carrier tape roll 42 is mounted within the body 1, and a clearance hole 43 and a second notch 50 are provided at the top of the body 1 for the carrier tape to pass through. To ensure stable transport of the carrier tape, the carrier tape conveyor 3 also includes a connecting arm 37 hinged to the conveyor frame 7. The middle portion of the connecting arm 37 is connected to the conveyor frame 7 via a spring 38. A mounting shaft 39 is fixed to the end of the conveyor frame 7. The end of the mounting shaft 39 is rotatably connected to a pressure roller 40. The sidewall of the pressure roller 40 is also provided with a clearance groove 41 for passing the positioning protrusion 32.

[0065] The sealing tape conveyor 4 is also mounted on the mounting plate 10 and comprises a sealing tape roll 44 and multiple guide rollers 45. A baffle 46 is fixed to the top of the conveyor frame 7, facing the track groove 8. A V-shaped plate 47 is hinged to the mounting plate 10 via a rotating shaft, with two guide rollers 45 pivotally connected to each end of the V-shaped plate 47. One side of the V-shaped plate 47 is connected to the mounting plate 10 via a return spring 48, while a corner of the baffle 46 is provided with a first notch 49 for the sealing tape to pass through. After being guided by the guide rollers 45, the sealing tape roll 44 passes through the first notch 49 and enters the bottom of the baffle 46.

[0066] The pressing device 5 comprises a cylinder 51 fixed to the mounting plate 10. A pressure block 52 is fixed to the output shaft of the cylinder 51. Two pressure strips 53 are located at the bottom of the pressure block 52. The baffle 46 has a strip-shaped hole 54, and the pressure strips 53 are positioned opposite the strip holes 54. When the sealing tape and the carrier tape body need to be pressed together, the cylinder 51 drives the pressure block 52 and pressure strips 53 downward, pressing the two together tightly.

[0067] Finally, the device also includes a winding device 55, which consists of a mounting base 56, a winding motor 57 fixed to one side of the mounting base 56, and a winding reel 58 mounted on the output shaft of the winding motor 57. A guide wheel 59 is also rotatably connected to the mounting base 56 to guide the strip loaded with the plastic product and smoothly wind it around the winding reel 58. During the entire process, the carrier tape is unloaded from the main material roll 42, passes through the avoidance hole 43, the second notch 50, the driven roller 31, the track groove 8, the driven roller 31, and the guide wheel 59, and is finally wound around the winding reel 58, completing the entire loading and winding process.

[0068] The present invention also provides a method for using a plastic product automatic loading belt device, comprising the following steps:

[0069] Plastic product sorting and conveying:

[0070] The plastic products are placed in the vibration plate 2 , and through the vibration, the plastic products are neatly arranged and transported forward along the conveying track 6 .

[0071] Transfer device working:

[0072] When the plastic product reaches the end of the conveyor track 6, the transfer device 9 starts to work. The stepper motor 18 drives the swing rod 19 to swing back and forth. The swing rod 19 is linked with the waist groove 20 and the driving rod 17 to move the Z-axis track 15 and the T-shaped frame 22 thereon in the vertical direction.

[0073] At the same time, the suction cup rod 24 moves left and right in the X-axis slide 23 , cooperating with the up and down movement of the Z-axis track 15 , to ensure that the suction cup 29 can accurately contact the plastic product on the conveying track 6 .

[0074] After the suction cup 29 absorbs the plastic product, the stepper motor 18 continues to drive, so that the suction cup 29 moves with the plastic product to above the track groove 8 of the carrier body conveying device 3.

[0075] During this process, the suction cup rod 24 moves in the adjustment slide 25, and the spacing between the first longitudinal portion 26 and the second longitudinal portion 27 is adjusted to achieve equal spacing adjustment of the suction cups 29, ensuring that the plastic product can be accurately placed in the receiving groove in the carrier body.

[0076] Carrier body conveying and positioning:

[0077] The carrier body is unwound from the carrier body raw material roll 42 , passes through the avoidance hole 43 and the second notch 50 in sequence, and is transported to the track groove 8 on the transport frame 7 .

[0078] The active roller 30 and the driven roller 31 cooperate with the carrier tape body through the positioning protrusion 32 on the side wall to achieve stable transportation of the carrier tape body.

[0079] A dual-axis motor 33 drives the active roller 30, while a sensor plate 35 rotates along the other output shaft of the dual-axis motor 33. When a U-shaped photoelectric sensor 34 detects a light-transmitting slot 36 on the sensor plate 35, it sends a signal to the controller, which stops the dual-axis motor 33. This periodically stops the carrier tape, facilitating precise placement of plastic products.

[0080] Sealing strip conveying and pressing:

[0081] The sealing tape is unwound from the sealing tape roll 44 , guided by a plurality of guide rollers 45 , and enters the bottom of the baffle 46 along the first notch 49 .

[0082] When the carrier tape body and the sealing tape are in place, the cylinder 51 of the pressing device 5 drives the pressing block 52 and the pressing strip 53 to move downward. The pressing strip 53 passes through the strip hole 54 and presses the connection between the sealing tape and the carrier tape body to achieve pressing.

[0083] Winding and finished product output:

[0084] The pressed carrier tape body and the sealing tape continue to be transported forward and eventually reach the winding device 55 .

[0085] The winding motor 57 rotates to drive the winding drum 58 to rotate, and the strip loaded with the plastic product is wound onto the winding drum 58.

[0086] The guide wheel 59 is used to guide the conveying path of the strip to ensure that the strip can be smoothly wound on the winding drum 58.

[0087] Pressure wheel positioning and spring buffer:

[0088] The pressure wheel 40 can stably position the carrier tape body through the action of the spring 38 and the connecting arm 37 , and can avoid the positioning protrusion 32 at the same time, thereby ensuring smooth transportation of the carrier tape body.

[0089] The spring 38 provides a certain buffering effect, which can reduce the vibration and deviation of the carrier body during the transportation process.

[0090] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
