DETAILED DESCRIPTION

[0065] Please refer to Figure 1 , Figure 1A and Figure 2 , which show the perspective view and top view schematic diagram of the manufacturing equipment 10 of the weight block of the sports equipment provided by a preferred embodiment of the present application. The manufacturing equipment 10 is an automatic equipment, which can automatically manufacture the weight block 90 (90A, 90B) shown in Figure 27A and Figure 27B by automatic control or program control. The manufacturing equipment 10 of the embodiment can be divided into three working stations. The first working station has one or more sheet body carrying devices 20, which carry one or more specifications of sheet bodies of metal material (hereinafter referred to as sheet body or metal sheet body). The second working station is an aligning machine 30, which is used to align the metal sheet body picked from the first working station. The third working station is an assembling machine 50, which stacks and fixes the metal sheet body of the second working station, thereby manufacturing Figure 27A or Figure 27BThe counterweight 90 is produced. Through the automated, continuous operation of these three workstations, metal sheets can be continuously and automatically manufactured into counterweights. The continuous and automated operation refers to the three workstations operating continuously, performing their respective work processes. The manufacturing equipment 10 has a transfer device that moves the sheet from the first workstation to the second workstation. After the second workstation performs appropriate operations on the sheet, the transfer device moves the sheet from the second workstation to the third workstation for subsequent operations. In this preferred embodiment, the transfer device includes a transfer mechanism 40 and a moving mechanism 80. The transfer mechanism 40 is located between the first and second workstations, moving a predetermined number of sheets from the first workstation to the second workstation. The moving mechanism 80 is located between the second and third workstations, or at the third workstation, for moving sheets from the second workstation to the third workstation.

[0066] Please see Figure 3 and Figure 5 In this embodiment, three sheet carrier devices 20 are provided at the first workstation to provide a plurality of sheets 22 to be assembled. Each sheet carrier device 20 has a hollow frame, forming an internal accommodating space that can hold four rows of sheets 22. The sheet carrier device 20 is movable, for example, in the form of a trolley, so that after loading the sheets 22, the sheets 22 can be easily moved to the first workstation. The transfer mechanism 40 picks up the sheets 22 from the sheet carrier device 20 and moves the sheets 22 to the second workstation. The three sheet carrier devices 20 can load sheets 22 of the same or different specifications as needed, and the different specifications of the sheets 22 have different shapes or outer diameters. Figure 3 The three sheet-bearing devices 20 are equipped with sheet bodies 22 of different specifications (22A to 22C), and each sheet body 22 is provided with several alignment holes 23, such as... Figure 27A As shown.

[0067] The transfer mechanism 40 can be any structure capable of moving the iron sheet 22. In this embodiment, the transfer mechanism 40 is a suction device, comprising: three sets of suction heads 42 mounted on a track assembly 44. The three sets of suction heads 42 correspond to the three sheet-carrying devices 20 respectively. The track assembly 44 drives the three sets of suction heads 42 to reciprocate between the first workstation and the second workstation. Please refer to... Figure 4Each set of suction heads 42 picks up one sheet 22 from a row of sheets, and each suction head 42 is equipped with an infrared detection element 46 on one side to detect the sheet 22 and confirm whether the suction head 42 has indeed picked up the sheet 22. If the suction head 42 does not pick up the sheet 22, an error signal will be issued. After the suction head 42 picks up the sheet 22, the track group 44 moves the suction head 42 and the sheet 22 from the first workstation to the second workstation. In this embodiment, each set of suction heads 42 picks up and moves one sheet 22 to the second workstation at a time. In practice, different structures of the transfer mechanism 40 can be selected, such as a robotic arm or a gripper, so that multiple sheets 22 can be gripped from the first workstation and moved to the second workstation at a time.

[0068] Please see Figure 5 Each sheet-carrying device 20 is equipped with a lifting mechanism 24, which can rise or fall. Each row of sheets 20 is placed on the lifting mechanism 24. Each sheet-carrying device 20 also has an infrared detection component 26 on its top surface to detect the position and height of each row of sheets 22, thereby controlling the operation of the lifting mechanism 24. When the picking mechanism 40 removes a sheet 20, the infrared detection component 26 detects that the height of the sheet 22 is insufficient. Its detection signal drives the lifting mechanism 24 to rise, causing each row of sheets to rise, so that the topmost sheet 22 rises to the height to be picked up. When each row of sheets has been removed, the lifting mechanism 24 is lowered to allow new sheets to be loaded into the sheet-carrying device 20. The lifting mechanism can be a pneumatic cylinder, a hydraulic cylinder, a linkage driven by a stepper motor, or a similar structure.

[0069] Please see Figure 6 The alignment machine 30 has three picking platforms 32, corresponding to the three wafer carriers 20 and the three sets of suction heads 42, respectively. Each picking platform 32 has a first placement position 33 and a second placement position 34 at each end for placing the wafer 22, and each placement position 33, 34 has a stop 35 on its inner side. The alignment machine 30 also includes three pushers 36, each movable by a driving component, such as a pneumatic cylinder 37, or a similar driving component. These three pushers 36 correspond to the three picking platforms 32. The stop 35 and the corresponding pusher 36 of each picking platform 32 form a pair of alignment components for aligning the wafer 22 on the picking platform 32. Please refer to... Figure 5 Each inspection platform 32 is provided with at least one positioning pin 38 below it. The positioning pin 38 is driven by a driving component, such as a pneumatic cylinder 39, or a similar component, and can extend upward through the inspection platform 32 or retract downward below the inspection platform.

[0070] The retrieval platform 32 is rotatable, allowing the first placement position 33 and the second placement position 34 to be interchanged. Please refer to [link / reference]. Figure 8When a set number of wafers 22 are placed at the placement position 33 of the picking platform 32, for example, 5 or 6 wafers, the picking platform 32 will be driven to rotate. Figure 9 As shown. The inspection platform 32 will rotate 180 degrees, as... Figure 10 and Figure 7 The stacked pieces 22 on the first placement position 33 face the pusher 36, while the second placement position 34 of the pick-up platform 32 faces the first workstation. Next, the pneumatic cylinder 37 drives the pusher 36 to move towards the pieces 22. The pusher 36 pushes the stacked pieces 22 from the circumferential surface of the pieces towards the stop block 35 and tightens them. The pusher 36 and the stop block 35 hold the circumferential surface of the pieces, aligning the pieces 22 vertically. Then, the positioning pin 38 rises, as... Figure 7 and Figure 10 The pieces 22 are aligned through the alignment holes 23, thus precisely positioning them and forming a unit A composed of a predetermined number of pieces 22. Afterwards, the pusher 36 and positioning pin 38 retract (the pusher 36 leaves the piece, and the positioning pin 38 descends and passes through the piece), no longer pressing the piece. Next, the moving mechanism 80 moves the positioned unit A to the third workstation, where it is assembled by the assembly machine 50. After unit A is removed by the moving mechanism 80, there are no pieces on the placement position 33.

[0071] At Figure 10 During the positioning process of the wafer 22 at placement position 33, the transfer mechanism 40 continuously retrieves wafers 22 from the first workstation and places them at placement position 34. Similarly, once the number of wafers 22 at placement position 34 reaches the set quantity, the retrieval platform 32 will rotate 180 degrees again, causing placement position 34 to face the pusher 36, positioning the wafers at placement position 34 by the pusher 36, the stop block 35, and the positioning pin 38; while placement position 33 is then used to place new wafers.

[0072] Please see Figure 11 The assembly machine 50 has at least three consecutive working positions for stacking unit A, thickness inspection, and installing fixing pins. These at least three consecutive working positions are arranged sequentially. In this embodiment, the assembly machine 50 is an automated machine and provides four working positions I, II, III, and IV, spaced 90 degrees apart. These four working positions are formed on a turntable 51, which is mounted on a frame and driven by a transmission mechanism (e.g., a stepper motor). Four bearings 52 are arranged on the turntable 51 at 90-degree angles, corresponding to the four working positions. The turntable 51 rotates in 90-degree steps, causing the four bearings 52 to move cyclically between the four working positions I, II, III, and IV. Please refer to [link to relevant documentation]. Figure 13Each bearing 52 is provided with a plurality of retractable guide pins 54, each guide pin 54 being stepped, having a large diameter portion 541 and a small diameter portion 542 located at the top of the large diameter portion 541. The guide pins 54 are installed in the seat body 53 of the bearing 52. Under normal conditions, the guide pins 54 are held by the elastic element 531 located in the seat body 53, and their tops protrude upward from the seat body 53.

[0073] A thickness detection mechanism 55 is mounted on the frame of the assembly machine 50 and corresponds to the second working position II. The assembly machine 50 further includes an assembly mechanism mounted on the frame and corresponding to the third working position III. The assembly mechanism secures the stacked sheets with at least one fixing element. The assembly mechanism includes a fixing pin clamping mechanism 60 and a pressure mechanism 70, which also corresponds to the third working position III.

[0074] Preferably, the moving mechanism 80 is a multi-axial robotic arm with a gripper at its front end, capable of gripping and placing plates at multiple axes and angles. Please refer to [link / reference]. Figure 12 As previously described, the moving mechanism 80 moves the positioned unit A from the second workstation to the third workstation. According to its programmed settings, the moving mechanism 80 picks up several units A from the self-checking platform 32 and stacks them at the first position I of the turntable 51. The moving mechanism 80 can, according to its settings, pick up units A formed from sheets 22 of the same specifications (e.g., units formed from sheets 22A), or units A formed from sheets 22 of different specifications (e.g., units formed from sheets 22A, 22B, or 22C). The moving mechanism 80 stacks several units A at the first working position I to form the finished product B of the counterweight block. Please refer to [link to relevant documentation]. Figure 13 When unit A is stacked in the first working position I, it is placed on the seat 53 of the support 52, and the guide pin 54 passes through the alignment hole 23 of the plate 22. The large diameter portion 541 of the guide pin 54 enters the alignment hole 23 of unit A, and the diameter of the large diameter portion 541 is approximately equal to and slightly smaller than the diameter of the alignment hole 23; while the small diameter portion 542 of the guide pin 54 extends upward out of unit A. The plates 22 of the plurality of unit A in the first working position I remain aligned.

[0075] Next, as Figure 14 As shown, the turntable 51 rotates 90 degrees, moving the finished product B, formed by stacking sheet bodies 22, to the second working position II for thickness detection. During thickness detection, the moving mechanism 80 can continue to pick up new unit bodies from the second workstation and stack them at the first working position I.

[0076] The thickness detection mechanism 55 has a support 56 and a probe 57 mounted on the support 56 and movable up and down. Please refer to [link / reference]. Figure 15When the probe 57 of the thickness detection mechanism 55 moves downward and touches the workpiece B to be finished, it detects the thickness of the workpiece B. After detection, the probe 57 moves upward back to its original position. If the detection result is correct, the turntable 51 will rotate another 90 degrees, moving the workpiece B to the third working position III. If the thickness of the workpiece is incorrect after detection, an error signal will be issued, and it will be displayed as a defective product.

[0077] Please see Figure 16 , Figure 17 The turntable 51 moves the workpiece to be completed to the third working position III. The assembly machine 50 fixes the workpiece B to be completed at the third working position III with at least one fixing element, and makes the workpiece B into a counterweight.

[0078] In this preferred embodiment, the fixing element is a fixing pin, and the assembly machine 50 uses an assembly mechanism to attach at least one fixing pin 58 (e.g., Figure 18 (As shown) Insert it into the finished product B to fix the sheet 22 of the finished product B.

[0079] The aforementioned fixed pin clamping mechanism 60 is installed around the third working position III and includes: a first clamp and a second clamp. The first clamp is a rotating clamp 61 and a movable clamp 64. The jaws 62 of the rotating clamp 61 can rotate between a horizontal position and a vertical position. The second clamp is a movable clamp 64, which is installed on a track assembly 66. Through the track assembly 66, the movable clamp 64 can move left and right along the X-axis, move forward and backward along the Y-axis, and move up and down along the Z-axis.

[0080] A vibratory feeder (not shown) is installed in a housing 67, and a conveyor 68 is disposed between the vibratory feeder and the rotating clamp 61. The vibratory feeder contains a large number of retaining pins; please refer to [reference needed]. Figure 18 Through the vibration of the vibrating plate, the fixing pins 58 are sequentially transported from the conveyor 68 to the rotating chuck 61. Figure 18 The rotating chuck 61 shows that the jaws 62 grip a horizontally positioned fixing pin 58.

[0081] Next, as Figure 19 The rotating chuck 61 rotates 90 degrees, uprighting the fixing pin 58; the movable chuck 64 returns to its original position. Figure 20 As shown, the movable chuck 64 descends along the Z-axis, causing its jaws 65 to clamp the retaining pin 58. Then, the movable chuck 64, carrying the retaining pin 58, moves three-dimensionally along the X, Y, and Z axes via the track assembly 66, fitting the retaining pin 58 onto a guide pin 54 of the bearing 52, as shown. Figure 21As shown. The fixing pin 58 is a hollow tube, and the diameter of its inner hole 581 is equal to and slightly larger than the outer diameter of the small diameter portion 542 of the guide pin 54. Therefore, the fixing pin 541 is only fitted on the small diameter portion 542 of the guide pin, and its bottom end rests on the top end of the large diameter portion 541.

[0082] Figure 21 In addition to showing that the first retaining pin 58 is fitted onto a guide pin 54, it also shows that the movable chuck 64 has gripped the second retaining pin 58a by rotating the rotating chuck 61 (the movable chuck grips the second retaining pin in the following manner...). Figure 18 to Figure 20 (as shown), and moves toward the support 52. Figure 22 This shows the state in which the movable chuck 64 has the second retaining pin 58a fitted onto the small diameter portion of another guide pin 54.

[0083] Following the above actions, at the third working position III, the fixing pin clamping mechanism 60 places the four fixing pins 58 onto the four guide pins 54 of the bearing 52, thus completing the fixing pin placement operation.

[0084] Subsequently, such as Figure 23 As shown, the pressure mechanism 70 uses a drive component, such as a hydraulic cylinder, pneumatic cylinder, or similar component, to drive a pressure table 72 downward, pressing the fixing pins 58 into the finished product B. Because the guide pins 54 are telescopic, the pressure from the pressure mechanism 70 is applied to the guide pins 54 through the fixing pins 58. Under the pressure of the pressure mechanism 70, the guide pins 54 move into the seat 53, forcing the four fixing pins 58 into the alignment holes 23 of the sheet body 22. The outer diameter of the fixing pins 58 is slightly larger than the diameter of the alignment holes 23; therefore, the fixing pins 58 press against the alignment holes 23, thereby fixing the sheet body 22 of the finished product B. At other work positions I and II, the stacking of unit bodies A and thickness detection are performed simultaneously.

[0085] After pressing the fixing pin 58 into the finished product B to complete the fixing operation, the counterweight is finished. The pressure table 72 rises, and the turntable 51 rotates 90 degrees again. Figure 25 As shown, move the counterweight 90 to the fourth working position IV, and finally, as... Figure 26 The moving mechanism 80 clamps the counterweight 90 and moves it to the finished product area 85, thus completing the manufacturing process of the counterweight 90. After the counterweight 90 is removed from the support 52, the four guide pins 54 of the support are pushed out of the seat body 53 by the elastic element 541.

[0086] Figure 27A The display shows a counterweight 90A made of sheet 22 and unit A of the same specifications, with a uniform width. Figure 27BThe display shows a counterweight 90B made from sheet materials (22A to 22C) of different specifications and unit A, with its outer diameter arranged in a stepped pattern.
