[0047] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0048] like Figures 1 to 19 As shown, the elastic coefficient testing device of a pickle ball described in this embodiment is applied to the elastic coefficient testing of a pickle ball, and includes a base plate 5, a switching drive mechanism mounted on the base plate 5, a counting adjustment mechanism mounted on the base plate 5 and arranged on one side of the switching drive mechanism, a photographing member 3 mounted on the base plate 5 and arranged on the other side of the switching drive mechanism, and a pick-up and release mechanism mounted above the switching drive mechanism; the counting adjustment mechanism is in transmission connection with the switching drive mechanism, so that after a preset count value is reached, the counting adjustment mechanism drives the switching drive mechanism to drive the protective frame 14 to rotate, thereby performing elasticity tests on different test plates 15; preferably, the photographing member 3 is an industrial camera;

[0049] The switching drive mechanism includes a plurality of protective frames 14; the protective frames 14 are made of a transparent material; the number of protective frames 14 can be set according to actual design needs, such as Figure 12 and Figure 13As shown, the present embodiment provides three protective frames 14, each of which is provided with a test board 15. Each test board 15 is made of different materials, and the specific material can be selected according to the actual test needs; the test board 15 is provided with a low-position picking position 151, by setting the low-position picking position 151, so that the pickle ball can automatically return to the low-position picking position 151 after bouncing, so that the pickle ball can be grabbed by the pick-up release mechanism; the switching drive mechanism is provided with a first discharge port at the position corresponding to the low-position picking position 151, so that the unqualified pickle ball can be removed from the protective frame 1 through the first discharge port. 4. Collection of unqualified pickle balls; the first discharge port sequentially penetrates the test plate 15 and the protective frame 14; the switching drive mechanism is further provided with a second discharge port on the side of the low-position pickup position 151, and the second discharge port sequentially penetrates the test plate 15 and the protective frame 14; the second discharge port is provided with a guiding slope so that qualified pickle balls can be moved out of the protective frame 14 through the second discharge port, thereby realizing automatic discharge of qualified pickle balls; the first discharge port is provided with a first electric-controlled door 17, and the second discharge port is provided with a second electric-controlled door 18; when the pickle ball is located at the low-position pickup position 151, the pickle ball abuts against the second electric-controlled door 18;

[0050] The elastic coefficient testing device also includes a first conveying mechanism 6 located on one side of the switching drive mechanism, a second conveying mechanism 7 located on the other side of the switching drive mechanism, and a collection bin 8 located below the switching drive mechanism. The first conveying mechanism 6 is used to convey the pickle balls to be tested; the second conveying mechanism 7 is used to convey the pickle balls that have passed the test; and the collection bin 8 is used to collect the pickle balls that have failed the test. Preferably, both the first conveying mechanism 6 and the second conveying mechanism 7 are existing conveyor belt structures, and the width of the conveyor belt structure is adapted to the size of the pickle balls.

[0051] Preferably, the shooting component 3 may also have a built-in data processing unit; the shooting component 3 may be configured to communicate with an external terminal, such as by using Bluetooth, a local area network, or a wireless network; the external terminal may be a computer or a handheld portable terminal so that the user can view real-time detection data and detection records.

[0052] When the elastic coefficient testing device of this embodiment performs an elasticity test on the pickle ball, the switching driving mechanism rotates one of the protective frames 14 to the loading station, and the first conveying mechanism 6 conveys the pickle ball to be tested into the protective frame 14. The pickle ball entering the protective frame 14 rolls to the low picking position 151 and abuts against the second electric control door 18; then the protective frame 14 carrying the pickle ball to be tested is driven to move to the testing station, and the picking and releasing mechanism grabs and releases the pickle ball located at the low picking position 151, and the counting and adjusting mechanism counts the number of grabs of the picking and releasing mechanism, and the industrial camera records the motion trajectory of the pickle ball after release and transmits the detection data to the data processing unit until the pickle ball completes the preset number of grabs and releases; the data processing unit analyzes the motion trajectory of the pickle ball after detection and determines whether the pickle ball is qualified; the switching driving mechanism drives the protective frame 14 to rotate to the unloading station, at which time the first unloading port is located directly above the collecting bin 8, and the second unloading port corresponds to the position of the second conveying mechanism 7;

[0053] At this time, if the pickle ball is judged to be qualified, the second electric control door 18 is controlled to open, and the qualified pickle ball rolls from the second unloading port to the second conveying mechanism 7 through the guide slope. The second conveying mechanism 7 conveys the qualified pickle ball to the next process, so that the pickle ball moves out of the unloading station;

[0054] If the pickle ball is judged to be unqualified, the first electric control door 17 is controlled to open, and the pickle ball that has passed the test falls into the collection bin 8 through the first discharge port;

[0055] In this way, by switching the driving mechanism, the protective frame 14 is driven to move cyclically between the loading station, the detection station, and the unloading station, thereby realizing automatic and continuous detection of pickle balls, improving the detection efficiency of pickle balls, and helping to improve the detection accuracy, which is suitable for the use scenario of large-scale pickle ball detection.

[0056] like Figure 2 、 Figures 7 to 9 As shown, in the elastic coefficient detection device of this embodiment, in some embodiments, the picking and releasing mechanism includes a guide rail 42, a lifting power member 43 slidingly arranged on the guide rail 42, and a sleeve 44 arranged at the output end of the lifting power member 43; both ends of the guide rail 42 are fixedly connected to the columns 41, and the columns 41 provide support for the guide rail 42 to ensure the horizontality and stability of the guide rail 42; a downwardly extending guide plate 421 is provided in the middle of the guide rail 42; the guide plate 421 is provided with a driving hole, a vertically sliding guide frame 45 and a fixed push rod 46; the push rod 46 is L-shaped; the driving hole is provided with a picking point and a lowering point located above the picking point; the picking point and the lowering point are located on different vertical lines; the push rod 46 is located above the lowering point; as shown Figure 2 and Figure 9As shown, the lower end of sleeve 44 is provided with a snap-on fit; the snap-on fit allows the pickle ball to be trapped within sleeve 44; the upper end of sleeve 44 is provided with a center hole, through which a push rod 46 extends into sleeve 44, thereby squeezing the pickle ball within sleeve 44 and allowing it to pass through the snap-on fit and fall downward; a guide rod 441 extends horizontally from the side wall of sleeve 44; the end of guide rod 441 movably passes through the drive hole and is movably hinged to one end of guide frame 45; the other end of guide frame 45 is movably hinged to a counting adjustment mechanism, so that each upward movement of guide frame 45 drives the counting adjustment mechanism to count once. The lifting power element 43 is a power cylinder. In this embodiment, a notch is provided on the side of protective frame 14 near guide frame 45 to avoid the guide plate 421.

[0057] When performing a pickle ball elasticity test, one of the test plates 15 is placed at the testing station, which is located directly below the push rod 46. The tester places the pickle ball into the sleeve 44 through the bayonet, and the power cylinder places the guide rod 441 at the pick-up point of the drive hole. At this time, the initialization of the testing equipment is completed;

[0058] Then the power cylinder drives the sleeve 44 to move upward, so that the guide rod 441 moves from the pick-up point position to the drop point position. Figure 1 As shown, at the same time, the guide rod 441 drives the guide frame 45 to move upward; when the guide rod 441 moves to the position just below the lowering point, the guide frame 45 starts to drive the counting adjustment mechanism to perform the counting action. As the sleeve 44 moves further upward, the push rod 46 extends into the sleeve 44 through the center hole, squeezing the pickle ball in the sleeve 44 until the diameter cross section of the pickle ball just exceeds the bayonet. At this time, the pickle ball can pass through the bayonet under its own weight and fall downward into the protective frame 14 until the guide rod 441 moves to the lowering point. Figure 6 As shown, the counting adjustment mechanism completes one count at this time; during the contact process between the pickle ball and the test board 15, the industrial camera records the detection data such as the bounce height and bounce trajectory of the pickle ball each time it falls in real time until the pickle ball stops at the low pick-up position 151 of the test board 15, thus completing one detection;

[0059] Then the power cylinder drives the sleeve 44 to move downward, so that the guide rod 441 is reset to the picking point position. At this time, the sleeve 44 inserts the pickle ball located at the low picking position 151 into the sleeve 44 through the bayonet to pick up the pickle ball. Then the above action is repeated until the preset number of tests of the current test board 15 is completed. The industrial camera records the test data of each test, analyzes and processes the test data according to the preset elastic coefficient calculation formula, and averages the multiple test data to accurately evaluate the elastic coefficient of the current pickle ball, compare the landing point of the ball with the preset qualified landing point range, and determine whether the pickle ball is qualified; the counting adjustment mechanism drives the switching drive mechanism to drive the protective frame 14 to rotate a certain angle, such as 120 degrees, so that the next protective frame 14 drives the next test board 15 to rotate to the detection station;

[0060] Next, the tester places the pickle ball into the sleeve 44 again and repeats the above steps to complete the test of the next test board 15. This continues until all test boards 15 are tested.

[0061] The industrial camera analyzes the test data of each pickle ball on the test board 15 of different materials and generates a test report; the test report contains information such as the elastic coefficient, landing point of each pickle ball on the inclined board of different materials, and whether the product is qualified or not, so as to provide comprehensive evaluation and analysis of product quality.

[0062] This embodiment simulates a variety of actual usage scenarios by setting up multiple test boards 15, so that the elastic coefficient of the pickle ball can be tested on surfaces of different materials, thereby improving the comprehensiveness and reliability of the test results, and can more realistically reflect the performance of the pickle ball under various usage scenarios, providing richer and more accurate data support for product quality evaluation.

[0063] This embodiment sets a low-position picking position 151 on the test plate 15, so that under the drive of the lifting power part 43, the cooperation between the top rod 46 and the sleeve 44, the cooperation between the guide rod 441 and the drive hole, the cooperation between the guide frame 45 and the counting adjustment mechanism, and the cooperation between the counting adjustment mechanism and the switching drive mechanism are utilized to automatically complete the release and reset of the pickle ball and the switching action of the test plate 15 associated with the number of tests during the detection process, thereby reducing manual intervention, making the entire detection process coherent and efficient, shortening the detection time, and improving the detection efficiency. It is suitable for large-scale pickle ball elasticity detection scenarios.

[0064] like Figure 7 and Figure 8As shown, in the elastic coefficient detection device of this embodiment, in some embodiments, the driving hole includes a first vertical section 4211, an inclined section 4212 and a second vertical section 4213; the two ends of the inclined section 4212 are respectively connected to the first vertical section 4211 and the second vertical section 4213; the picking point is arranged at the lower end of the first vertical section 4211; and the lowering point is arranged at the upper end of the second vertical section 4213. Specifically, this embodiment provides a first vertical section 4211 so that when the guide rod 441 moves vertically downward in the first vertical section 4211, the sleeve 44 can insert the pickle ball located at the low picking position 151, thereby realizing automatic picking up of the pickle ball; a second vertical section 4213 is provided so that when the guide rod 441 moves upward along the second vertical section 4213, the top rod 46 can reliably extend into the sleeve 44 to squeeze the pickle ball in the sleeve 44, thereby realizing automatic release of the pickle ball; an inclined section 4212 is provided so that the guide rod 441 can automatically adapt to the height change of the sleeve 44, and the inclined section 4212 cooperates with the guide rod 441 so that the sleeve 44 can switch between the picking point position and the lowering point position.

[0065] like Figure 7 and Figure 8 As shown, in the elastic modulus testing device of this embodiment, in some embodiments, the guide plate 421 is further provided with a vertically extending first limiting hole 4214; the guide frame 45 is provided with a first limiting pin 451; and the first limiting pin 451 is movably embedded in the first limiting hole 4214. In this embodiment, the first limiting hole 4214 cooperates with the first limiting pin 451 to restrict the horizontal freedom of the guide frame 45, so that the guide frame 45 can only move in the vertical direction, thereby providing guidance and limiting for the guide frame 45.

[0066] like Figure 7 and Figure 8 As shown, in some embodiments of the elastic modulus testing device of this embodiment, a horizontally extending guide hole 452 is provided at one end of the guide frame 45; the distal end of the guide rod 441 is movably inserted into the guide hole 452. In this embodiment, the guide hole 452 is provided to flexibly engage with the guide rod 441, thereby achieving linkage between the guide rod 441 and the guide frame 45, while also allowing the guide rod 441 to slide relative to the guide frame 45 to pick up and release the pickle ball.

[0067] like Figure 4 、 Figures 10 to 15As shown, the elastic coefficient detection device of this embodiment, in some embodiments, the counting adjustment mechanism includes an adjusting seat 21, a locking block 23 vertically slidingly arranged on the adjusting seat 21, a locking strip 24 movably arranged on the adjusting seat 21, a locking slider 25 horizontally slidingly arranged on the adjusting seat 21, a rocker 26 hinged at one end to the locking slider 25 and a latch 261 elastically floatingly arranged at the other end of the rocker 26; the adjusting seat 21 is provided with a plurality of latching positions 211 arranged in sequence along the vertical direction; the adjusting seat 21 is provided with a first limiting block 27 for cooperating with the locking slider 25 on one side of the latching position 211 for vertical sliding; the lower end of the adjusting seat 21 is provided with a first limiting block 27 for cooperating with the locking slider 25 on the other side of the latching position 211 Two limit blocks 28; the lower end of the locking strip 24 is fixedly connected to the locking slider 25; the upper end of the locking strip 24 is provided with a plurality of locking grooves 241 arranged in sequence along the vertical direction; a tension spring 232 is provided between the lower end of the locking block 23 and the adjustment seat 21; the upper end of the locking block 23 is elastically floatingly connected with a locking pin 231 for one-way locking cooperation with the locking groove 241; the upper end of the locking block 23 is also movably hinged to the other end of the guide frame 45, specifically, the other end of the guide frame 45 is provided with a vertically extending second limit hole 453, and the upper end of the locking block 23 is provided with a guide pin 233, which is movably embedded in the second limit hole 453; initially, the guide pin 233 abuts against the upper end of the second limit hole 453.

[0068] At the beginning, if Figure 10 As shown, the locking slider 25 is at the lowest point, the latch 261 is located below the lowest latching position 211 under the action of the second limit block 28, and the locking pin 231 is locked with the lock groove 241 at the top. According to the preset number of single pickle ball detections, the latching position 211 corresponding to the number of detections is determined, and the first limit block 27 is slid to the corresponding height position of the latching position 211 and the first limit block 27 is limited to keep the first limit block 27 at the current height.

[0069] When the guide rod 441 moves to the lower end of the second vertical section 4213, the guide frame 45 cooperates with the guide pin 233 through the second limiting hole 453, driving the locking block 23 to move upward to overcome the tension of the tension spring 232. At the same time, the locking block 23 synchronously drives the locking bar 24 to move upward through the one-way locking cooperation between the locking pin 231 and the locking groove 241. The locking bar 24 drives the locking slider 25 to move upward until the guide rod 441 moves to the lowering point. At this time, the latch pin 261 is locked in the lowest latching position 211.

[0070] The guide rod 441 is then moved from the picking point position to the placing point position, and the guide frame 45 drives the locking block 23 to move up again, and the locking block 23 drives the locking bar 24 to move up again, and at the same time, the latch 261 moves up to engage with the next lowest locking position 211, as shown in FIG. Figure 12 So reciprocating, when the locking slider 25 moves to cooperate with the first limit block 27, as shown Figure 13 As shown, the first limit block 27 drives the locking slider 25 to slide horizontally, and the locking slider 25 drives the locking bar 24 to move away from the locking block 23, so that the locking pin 231 moves out of the locking groove 241. At this time, the latch 261 moves out of the latching position 211, thereby releasing the restriction on the locking slider 25. At this time, the locking slider 25 and the locking bar 24 return downward under their own weight until the locking slider 25 engages with the second limit block 28 again, thus completing the counting of the number of detections.

[0071] In this embodiment, the highest point position of the locking slider 25 is limited by setting a first limit block 27 to cooperate with the locking slider 25, thereby corresponding to the number of detection times, and the lowest point position of the locking slider 25 is limited by setting a second limit block 28 to cooperate with the locking slider 25 to achieve the reset of the locking slider 25; by setting a one-way locking cooperation between the locking pin 231 and the locking groove 241, when the locking pin 231 moves upward, it can drive the locking bar 24 to move upward, and when the locking pin 231 moves downward, the position of the locking bar 24 is limited by the cooperation of the latch 261 and the latch position 211, so that the locking pin 231 and the locking groove 241 are disengaged from the locking cooperation, so that the locking bar 24 remains at the current moving height, thereby achieving the accumulation of the counting times.

[0072] like Figures 10 to 13As shown, in the elastic coefficient detection device of this embodiment, in some embodiments, the first limit block 27 is provided with a first downward inclined surface; the second limit block 28 is provided with a second upward inclined surface; the locking slider 25 is provided with a first extension arm 251 and a second extension arm 252 located below the first extension arm 251; the first extension arm 251 is centrally symmetrical with the second extension arm 252; the first extension arm 251 is provided with a third upward inclined surface; the second extension arm 252 is provided with a fourth downward inclined surface; a torsion spring 262 is connected between the rocker arm 26 and the locking slider 25; the torsion spring 262 makes the other end of the rocker arm 26 maintain a tendency to swing toward the locking position 211; by setting the torsion spring 262, the rocker arm 26 has a certain degree of freedom of swinging to adapt to the movement of the locking slider 25. Through the above-mentioned arrangement, in this embodiment, when the third inclined surface of the first extension arm 251 contacts the first inclined surface of the first limit block 27, as the locking slider 25 moves upward, the first limit block 27 applies a thrust to the locking slider 25, so that the locking slider 25 drives the locking bar 24 to move away from the locking block 23, so as to achieve the reset of the locking bar 24; and when the fourth inclined surface of the second extension arm 252 contacts the second inclined surface of the second limit block 28, the second limit block 28 applies a thrust to the locking slider 25, so that the locking slider 25 drives the locking bar 24 to move toward the locking block 23, so that the locking pin 231 can cooperate with the locking groove 241 again.

[0073] like Figures 10 to 13 As shown, in the elastic coefficient detection device of this embodiment, in some embodiments, the counting adjustment mechanism also includes an adjusting slider 22 that is vertically slidably arranged on the adjusting seat 21; the locking bar 24 is movably passed through the adjusting slider 22; the locking bar 24 can slide vertically and horizontally relative to the adjusting slider 22; the locking slider 25 is horizontally slidably connected to the adjusting slider 22; the adjusting slider 22 is provided with a driving part 221; the driving part 221 is transmission-connected to the switching driving mechanism to drive the switching driving mechanism to drive the protective frame 14 to rotate. Specifically, when the locking block 23 drives the locking bar 24 to move upward, the locking bar 24 drives the adjusting slider 22 to move upward through the locking slider 25. At this time, the adjusting slider 22 will not drive the switching drive mechanism to drive the protective frame 14 to rotate; when the first limit block 27 cooperates with the first extension arm 251, so that the locking pin 261 is released from the locking position 211, the adjusting slider 22, the locking slider 25, and the locking bar 24 move downward under their own weight. At this time, the driving part 221 can drive the switching drive mechanism to drive the protective frame 14 to rotate, so that the next test board 15 moves to the detection station, thereby realizing automatic switching of the test board 15.

[0074] like Figure 1 、 Figures 4 to 6 、 Figures 16 to 18As shown, in the elastic coefficient detection equipment of this embodiment, in some embodiments, the switching drive mechanism includes two centrally symmetrical machine bases 11; the two machine bases 11 are rotatably connected to the bogies 12; a plurality of bearing plates 13 are hinged between the two bogies 12; each bearing plate 13 is provided with a protective frame 14; one of the machine bases 11 is provided with a one-way drive component; the one-way drive component is connected to the corresponding bogie 12; the one-way drive component includes a second limit pin 1611 and a rotatably arranged friction sleeve 163; the friction sleeve 163 is in sliding friction contact with the driving part 221; one of the machine bases 11 is provided with a limit arc groove 111; the second limit pin 1611 is movably embedded in the limit arc groove 111.

[0075] When the adjusting slider 22 moves upward, the driving part 221 drives the friction sleeve 163 to rotate through friction force, and the friction sleeve 163 drives the one-way driving component to idle, and the second limit pin 1611 moves along the limit arc groove 111. When the second limit pin 1611 abuts against the end of the limit arc groove 111, the friction sleeve 163 idles. During this process, the one-way driving component will not drive the bogie 12 to rotate; when the adjusting slider 22 moves downward, the driving part 221 friction sleeve 163 rotates, and the friction sleeve 163 drives the one-way driving component to work. The one-way driving component drives the bogie 12 to rotate a certain angle, so that the next test plate 15 moves to the detection station, thereby realizing automatic switching of the test plate 15.

[0076] like Figures 16 to 19As shown, the elastic coefficient detection device of this embodiment, in some embodiments, the one-way drive assembly also includes a first ratchet 161 rotatably provided on the machine base 11 and a second ratchet 162 fixedly sleeved on the bogie 12; the first ratchet 161 is provided with a receiving hole on the side facing away from the machine base 11; the inner peripheral wall of the receiving hole is evenly distributed with one-way ratchet teeth 1612; the second ratchet 162 is located in the receiving hole; the outer peripheral wall of the second ratchet 162 is provided with an elastic pawl 1621; the elastic pawl 1621 is unidirectionally engaged with the one-way ratchet 1612; the friction sleeve 163 is rotatably sleeved on the outer peripheral wall of the first ratchet 161. Specifically, when the adjusting slider 22 moves upward, the driving part 221 drives the friction sleeve 163 to rotate through the friction force, and the friction sleeve 163 drives the first ratchet 161 to rotate. Since the one-way ratchet 1612 is unidirectionally meshed with the elastic pawl 1621, the first ratchet 161 rotates idly at this time until the second limit pin 1611 abuts against the end of the limit arc groove 111. At this time, the first ratchet 161 is restricted, and the friction sleeve 163 no longer drives the first ratchet 161 to rotate, that is, the friction sleeve 163 rotates idly. Rotate; when the adjustment slider 22 moves downward, the driving part 221 drives the friction sleeve 163 to rotate through friction force, and the friction sleeve 163 drives the first ratchet 161 to rotate through friction force, and the first ratchet 161 drives the second ratchet 162 to rotate through the one-way engagement of the one-way ratchet 1612 and the elastic pawl 1621, and the second ratchet 162 drives the bogie 12 to rotate until the second limit pin 1611 abuts against the other end of the limit arc groove 111, thereby realizing the switching of the test plate 15.
