[0001] This invention relates to the field of feed tray technology, and more specifically to a novel feed tray detection device. Background Technology

[0002] A feeding tray (vibratory feeder) is an auxiliary feeding device for automatic assembly or automatic processing machinery. It is widely used in various industries such as electronics, hardware, plastics, watchmaking, batteries, food, connectors, medical devices, pharmaceuticals, toys, stationery, and daily necessities manufacturing. It is an essential piece of equipment for solving the feeding problem of industrial automation equipment. It can arrange various products in an orderly manner and work with automatic assembly equipment to assemble the various parts of the product into a complete product, or work with automatic processing machinery to complete the processing of workpieces.

[0003] Currently, to improve production efficiency, an automatic feeding device has been installed. This device needs to detect whether there are products in the feeding tray. Currently, fiber optics are used to detect the presence of products in the tray and control the hopper's feeding. However, because the product color is similar to the feeding tray color, the detected feedback values ​​are also similar. Furthermore, the product heights are inconsistent, requiring constant adjustments. This results in frequent fluctuations in the number of products in the feeding tray, leading to a high machine alarm rate and impacting efficiency. Summary of the Invention

[0004] To overcome the above-mentioned defects of the prior art, the present invention provides a novel detection device for the feeding tray, which solves the problem that the current fiber optic detection method results in similar feedback values ​​because the color of the product is similar to that of the feeding tray, and the product height is inconsistent, requiring constant adjustments, which often leads to the phenomenon that the number of products in the feeding tray varies.

[0005] This invention provides the following technical solution: a novel detection device for a feeding tray, comprising, An adjustable bracket is used to support the installation of the testing device and to avoid vibration sources; A connecting bracket is hinged to an adjustable bracket for adjusting the detection angle of the detection device.

The top of the swing arm extends upward to form an extended arm, and the top of the extended arm extends into the slotted photoelectric switch. Multiple counterweights are detachably installed on one side of the swing arm.

[0009] As a further embodiment of the present invention, a second magnetic block is fixedly connected to one side of the extended arm, and a second mounting groove is provided on one side of the mounting plate. A first magnetic block that cooperates with the second magnetic block is detachably installed in the second mounting groove by screws. The centerline of the second mounting groove coincides with the centerline of the swing shaft.

[0010] As a further embodiment of the present invention, the pendulum component includes, The upper swing arm, omnidirectional ball, and lower swing arm are integrated, with the center lines of the upper and lower swing arms coinciding, and the diameter of the lower swing arm being larger than that of the upper swing arm. A ball sleeve is fitted onto the outer ring of a universal ball joint. A mounting bracket is fixedly connected to the outer wall of the ball sleeve, and the mounting bracket is installed on the side of the mounting plate by screws. At least four ball bearing slides are fixedly connected to the side of the mounting plate, a follower frame is slidably installed between the four ball bearing slides, a sensing plate is fixedly connected to the top of the follower frame, and the end of the sensing plate extends into the slotted photoelectric switch. The follower frame is rotatably mounted with a follower fork on its side. The follower fork forms a follower chamber that blocks the upper swing arm. The inner diameter of the follower chamber is equal to the diameter of the upper swing arm. The bottom end of the lower swing arm is fixedly connected to a lower sensing ball.

[0011] As a further embodiment of the present invention, the center of gravity of the pendulum component is located below the omnidirectional ball; The integrated upper swing arm, omnidirectional ball, and lower swing arm are initially in a vertical state, with the upper swing arm corresponding to the sensor plate; A vibration gap is left between the bottom end of the lower induction ball and the feeding tray, and the vibration gap is smaller than the thickness of the product in the feeding tray.

[0012] As a further embodiment of the present invention, at least two adjustment slots are provided on one side of the mounting plate, the two adjustment slots are opened in parallel, the mounting plate and the connecting bracket are installed perpendicularly, and the connecting bracket has two through holes that cooperate with the adjustment slots inside.

[0013] As a further embodiment of the present invention, the adjustable support includes, The upright frame and the side frame are fixedly connected and installed on the top side of the upright frame, and the top of the side frame has a plurality of equally spaced pin holes. An adjusting tube, which is sleeved on the outside of the side frame; The indexing pin has an internal threaded sleeve fixedly connected to the top of the adjusting tube. The indexing pin is threadedly installed inside the internal threaded sleeve, and the bottom end of the indexing pin passes through the adjusting tube and can mate with any pin hole.

[0014] As a further embodiment of the present invention, the end of the adjusting tube is fixedly connected to a shaft that is rotatably connected to the connecting bracket. A guide groove is provided on the outer circumference of the shaft, and a sliding sleeve that cooperates with the guide groove is sleeved on the outer side of the shaft. A plurality of arrayed inserts are provided on the top of the sliding sleeve, and a plurality of grooves that cooperate with the inserts are provided on the bottom of the connecting bracket. The shaft has an external thread on its outer circumference, and a wing nut is installed through the external thread. The sliding sleeve is located between the connecting bracket and the wing nut.

[0015] The technical effects and advantages of this invention are as follows: 1. The various adjustment structures of this invention (multi-position adjustment tube, adjustable angle and height of connecting bracket) and the different state designs of the pendulum component (vertical / tilted / omnidirectional ball structure) comprehensively solve the problems of unstable material quantity and high alarm rate caused by similar product colors and varying heights in traditional fiber optic detection, effectively improving production efficiency. 2. In the pendulum component of the present invention in its initial vertical state, the induction wheel and the feeding tray have a vibration gap smaller than the product thickness. When the product touches the pendulum, the pendulum arm rotates to keep the slotted photoelectric switch constantly lit (no feeding). When there is no product, the pendulum arm vertically blocks the switch (feeding), thus avoiding resonance and ensuring accurate detection.

[0016] 3. In the pendulum component of the present invention in its initial tilted state, the induction wheel contacts the feeding tray, the extended arm amplifies the rotation distance, and the magnetic block one and magnetic block two reduce micro-vibrations, prevent the pendulum arm from being blocked in the opposite direction, and improve lifespan and accuracy.

[0017] 4. In this invention, when the lower sensing ball is blocked by the product in the integrated upper swing arm, universal ball, and lower swing arm structure, the upper swing arm pushes the follower fork to drive the follower frame to slide along the four ball slides through the cooperation of the universal ball and the ball sleeve. The sensing plate is disengaged from the slotted photoelectric switch, which can reliably detect without precise installation and reduces the complexity of installation.

[0018] 5. This invention achieves multi-position locking by adjusting the tube sleeve on the side frame with multiple pin holes, and cooperating with the indexing pin and internal thread sleeve. It can flexibly adapt to different installation positions, avoid vibration sources, improve the operational stability of the detection device, and solve the problem of frequent debugging caused by the fixed position of traditional optical fiber detection.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figures 1-12 The present invention provides a novel detection device for a feeding tray, including an adjustable bracket 1 for mounting and supporting the detection device; The adjustable support 1 includes a vertical frame 101, a side frame 102, an adjusting tube 105, and an indexing pin 104. The side frame 102 is fixedly installed on the top side of the vertical frame 101 by bolts. The top of the side frame 102 has a plurality of equally spaced pin holes 103. The adjusting tube 105 is sleeved on the outside of the side frame 102. The top of the adjusting tube 105 is welded with an internal threaded sleeve 106. The indexing pin 104 is threaded into the internal threaded sleeve 106. The bottom end of the indexing pin 104 passes through the adjusting tube 105 and can engage with any of the pin holes 103.

[0034] like Figures 3-4As shown, specifically, the upright frame 101, as the main support structure of the adjustable support 1, can be installed on the workbench away from the feeding tray to avoid vibration sources and ensure the stability of the entire detection device during operation.

[0035] The side frame 102 provides multiple adjustment positions for the adjusting tube 105 through multiple pin holes 103. During adjustment, the indexing pin 104 inside the internal threaded sleeve 106 is rotated, allowing the bottom end of the indexing pin 104 to engage with different pin holes 103, thereby locking and fixing the adjusting tube 105 after it moves on the side frame 102 to adapt to different installation position requirements.

[0036] To ensure the accuracy of the installation location (e.g.) Figure 2 As shown), the angle can be adjusted via connecting bracket 2; The connecting bracket 2 and the adjustable bracket 1 are hinged together for adjusting the detection angle of the detection device. A mounting plate 3 is installed on one side of the connecting bracket 2, and the relative height between the mounting plate 3 and the connecting bracket 2 is adjustable. The end of the adjusting tube 105 is bolted to a shaft 10501 rotatably connected to the connecting bracket 2. A guide groove 10502 is formed on the outer circumference of the shaft 10501, and a sliding sleeve 10504 that mates with the guide groove 10502 is fitted onto the outer side of the shaft 10501. The top of 504 is provided with multiple arrayed inserts 10503, and the bottom of the connecting bracket 2 is provided with multiple grooves 201 that cooperate with the inserts 10503. The guide groove 10502 on the shaft 10501 plays a guiding role to ensure that the sliding sleeve 10504 can move accurately along the shaft 10501. The inserts 10503 on the top of the sliding sleeve 10504 cooperate with the grooves 201 at the bottom of the connecting bracket 2 to further ensure the stable engagement of the relative positions between the connecting bracket 2 and the shaft 10501.

[0037] The shaft 10501 has an external thread on its outer circumference, and a wing nut 10505 is installed through the external thread. The sliding sleeve 10504 is located between the connecting bracket 2 and the wing nut 10505.

[0038] like Figures 5-6 As shown, specifically, by rotating the connecting bracket 2, since the connecting bracket 2 is hinged to the adjustable bracket 1, the connecting bracket 2 can rotate around the hinge point, thereby changing the detection angle. After adjusting to the appropriate position, tighten the wing nut 10505. By using the engagement between the wing nut 10505 and the external thread on the shaft 10501, the insert 10503 on the top of the sliding sleeve 10504 is engaged with the groove 201 at the bottom of the connecting bracket 2, thereby fixing the position of the connecting bracket 2 and ensuring that the angle and position of the detection device will not change during the detection process. The mounting plate 3 has at least two adjustment slots 301 on one side, which are parallel to each other. The mounting plate 3 and the connecting bracket 2 are installed perpendicularly. The connecting bracket 2 has two through holes inside that mate with the adjustment slots 301. Furthermore, the relative height between the mounting plate 3 and the connecting bracket 2 can be adjusted according to actual installation needs to meet the requirements of different installation positions in various scenarios.

[0039] It should be noted that the feeding tray (vibrating plate) in this application is an auxiliary feeding device for automated production lines. Its core function is to automatically and orderly arrange disordered workpieces and transport them to the next process. When the equipment is powered on, the pulse electromagnet generates periodic electromagnetic force, which acts on the bottom of the hopper. At the same time, the inclined spring plates undergo elastic deformation due to the electromagnetic force, driving the hopper to perform a combined vertical vibration and torsional vibration motion around the vertical axis. Under the combined force of gravity and vibration, the workpieces in the hopper slowly rise along the spiral track. The spiral track design allows the workpiece to continuously adjust its posture during the ascent, which is prior art and can be set by those skilled in the art according to actual needs, and will not be elaborated here.

[0040] The pendulum component 4 is disposed on the side of the mounting plate 3 and is rotatably connected to the mounting plate 3. The slotted photoelectric switch 5 is installed on the side of the mounting plate 3 and above the pendulum component 4, and is used to detect whether the pendulum component 4 is in a swinging state.

[0041] The pendulum component 4 includes a pendulum shaft 401, a pendulum arm 402, and a sensing wheel 403. The pendulum shaft 401 and the pendulum arm 402 are rotatably mounted by bearings, and the pendulum shaft 401 is fixedly mounted on the side of the mounting plate 3. The induction wheel 403 is rotatably mounted on the bottom end of the swing arm 402 via a bearing, and the top end of the swing arm 402 extends into the slotted photoelectric switch 5; the center of gravity of the pendulum component 4 is below the pendulum shaft 401.

[0042] The pendulum component 4 can be divided into two states, which can be freely selected according to the usage.

[0043] State 1: The initial state of the swing arm 402 is vertical (e.g., Figure 3 (as shown) A vibration gap is left between the bottom end of the induction wheel 403 and the feeding tray, and the vibration gap is smaller than the thickness of the product in the feeding tray.

[0044] Specifically, when the feeding tray feeds the product into it, the product spirals upward along the edge of the feeding tray and touches the sensing wheel 403. At this time, the swing arm 402 rotates around the swing shaft 401 (the rotation direction of the swing arm 402 is the same as the spiral feeding direction of the product in the feeding tray), and the top of the swing arm 402 moves away from the slot photoelectric switch 5. The slot photoelectric switch 5 is in a constantly lit state, so there is still a product in the feeding tray. At this time, a signal is sent to the external hopper, and the external hopper does not feed the product into the feeding tray. When there is a lack of products in the feeding tray, there are no products to block the induction wheel 403, so the swing arm 402 returns to the vertical state. At this time, the top of the swing arm 402 blocks the slotted photoelectric switch 5, and sends a signal to the external hopper to make the external hopper deliver products into the feeding tray.

[0045] Meanwhile, based on the vibration gap between the sensing wheel 403 and the feeding tray and the thickness of the product in the feeding tray, it can be ensured that when the feeding tray is feeding normally and the product thickness is appropriate, the sensing wheel 403 can accurately sense the product (i.e., when it is blocked by the product, the swing arm 402 rotates around the swing axis 401), avoiding the impact of insufficient product thickness on the accuracy of the detection results; when there is no product, the sensing wheel 403 will not contact the feeding tray, effectively avoiding the situation where the sensing wheel 403 and the feeding tray resonate upon contact.

[0046] However, the following problems still exist during the detection process: when there are a few products in the feeding tray, the sensing wheel 403 will sometimes be blocked by the products, causing the swing arm 402 to rotate around the swing shaft 401; at other times it will not be blocked by the products, causing the swing arm 402 to rotate around the swing shaft 401 and reset. At this time, the swing arm 402 is prone to pendulum state around the swing shaft 401, and the slotted photoelectric switch 5 will be repeatedly blocked, affecting the accuracy of the detection results. Furthermore, when the swing arm 402 swings to the opposite direction, if a moving product appears below, the swing arm 402 will be blocked by the product in the opposite direction. This will cause the rotation direction of the swing arm 402 to be opposite to the spiral feeding direction of the product on the feeding tray, which will not only affect the accuracy of the detection results, but also affect the service life of the detection device.

[0047] State 2: The initial state of swing arm 402 is tilted (e.g., Figures 7-9 (as shown) At this time, the bottom end of the induction wheel 403 is in contact with the surface of the feeding tray, and the slotted photoelectric switch 5 is installed in the mounting arc groove 302 opened in the mounting plate 3. The center line of the mounting arc groove 302 coincides with the center line of the swing shaft 401. Therefore, the slotted photoelectric switch 5 can be adjusted in position in the mounting arc groove 302 according to different installation requirements.

[0048] The top of the swing arm 402 extends upward to form an extended arm 405, and the top of the extended arm 405 extends into the slotted photoelectric switch 5, thereby increasing the swing amplitude of the swing arm 402.

[0049] Specifically, at this time, the bottom end of the sensing wheel 403 is always in contact with the surface of the feeding tray. The slotted photoelectric switch 5 in this position is blocked by the extended arm 405. When the sensing wheel 403 presses over the product on the surface of the feeding tray, the swing arm 402 rotates around the swing shaft 401, and the extended arm 405 rotates with the swing arm 402 at the same time, amplifying the distance of rotation of the end of the extended arm 405 and causing the end of the extended arm 405 to disengage from the slotted photoelectric switch 5. Therefore, by adopting this tilted implementation method, the product testing effect can still be achieved, and the situation where the swing arm 402 swings to the opposite position can be effectively avoided.

[0050] Furthermore, multiple counterweights 404 are detachably installed on one side of the swing arm 402, and a second magnetic block 40502 is fixed to one side of the extended arm 405 by bolts. A second mounting groove 303 is opened on one side of the mounting plate 3, and a first magnetic block 40501 that cooperates with the second magnetic block 40502 is detachably installed in the second mounting groove 303 by screws. The center line of the second mounting groove 303 coincides with the center line of the swing shaft 401, which is used to synchronously adjust the installation position of the first magnetic block 40501. The counterweights 404 are used in conjunction with the extended arm 405 to prevent the center of gravity from exceeding the swing shaft 401. The complementary magnetic blocks 40502 and 40501 are used to solve the vibration problem. Since the bottom of the sensing wheel 403 needs to be in constant contact with the surface of the feeding tray when it is tilted, the vibration of the feeding tray will be transmitted to the sensing wheel 403 and the swing arm 402. This will cause the extended arm 405 to vibrate slightly, affecting the sensing accuracy of the slotted photoelectric switch 5. Therefore, the amplitude of the extended arm 405 is reduced by magnetic blocks 40502 and 40501, thereby improving the sensing accuracy of the slotted photoelectric switch 5.

[0051] In the above embodiment, the pendulum component 4 requires precise positioning during installation to ensure the perpendicular distribution of the induction wheel 403 to the surface of the feeding tray (e.g., Figure 2 (as shown in the image), which greatly increases the complexity of installation. Therefore, a device was designed that can still perform sensing operations without precise installation. The specific plan is as follows (please refer to...) Figures 10-12 ): The upper swing arm 413, the omnidirectional ball 412 and the lower swing arm 411 are integrated. The center lines of the upper swing arm 413 and the lower swing arm 411 coincide. The diameter of the lower swing arm 411 is larger than the diameter of the upper swing arm 413, so as to ensure that the center of gravity is below the omnidirectional ball 412. Ball sleeve 415 is fitted around the outer ring of universal ball 412. A mounting bracket 416 is welded to the outer wall of the ball sleeve 415, and the mounting bracket 416 is installed on the side of the mounting plate 3 by screws. At least four ball bearing slides 420 are fixed to the side of the mounting plate 3 by bolts. A follower frame 418 is slidably installed between the four ball bearing slides 420. A sensing plate 419 is fixed to the top of the follower frame 418 by bolts. The end of the sensing plate 419 extends into the slotted photoelectric switch 5. A follower fork 417 is rotatably mounted on the side of the follower frame 418. The follower fork 417 forms a follower chamber that blocks the upper swing arm 413. The inner diameter of the follower chamber is equal to the diameter of the upper swing arm 413. The bottom end of the lower swing arm 411 is fixed with a lower sensing ball 414 by bolts for contact with the product.

[0052] Therefore, when the lower sensing ball 414 is blocked by the product in the feeding tray, the lower sensing ball 414 will cause the lower swing arm 411 to drive the universal ball 412 and the upper swing arm 413 to rotate around the ball sleeve 415. Since the inner diameter of the follower chamber is equal to the diameter of the upper swing arm 413, the upper swing arm 413 will drive the follower frame 418 to slide along the four ball slides 420 through the follower fork 417. The sensing plate 419 moves with the movement of the follower frame 418, and the end of the sensing plate 419 is disengaged from the slot photoelectric switch 5. Even with a misalignment in the installation position, the upper swing arm 413 will still rotate due to the cooperation between the universal ball 412 and the ball sleeve 415 (e.g., Figure 12 (as shown) Assumption: When the upper swing arm 413 rotates to the upper left, since the follower fork 417 and the follower frame 418 are rotatably mounted, and the upper swing arm 413 can move in the follower chamber formed by the follower fork 417, it can still push the follower frame 418 to produce displacement. Therefore, with this implementation method, the detection device does not need to be precisely installed, yet the product detection effect can still be achieved.

[0053] It should be noted that the center of gravity of the pendulum component 4 in this embodiment is below the universal ball 412, thereby ensuring the smooth operation of the pendulum component 4. The initial state of the integrated upper swing arm 413, universal ball 412 and lower swing arm 411 is vertical. The upper swing arm 413 corresponds to the sensing plate 419. The bottom end of the lower sensing ball 414 leaves a vibration gap with the feeding tray, which is smaller than the thickness of the product in the feeding tray.

[0054] The effect of this setting is the same as Figure 3 The implementation methods shown are the same, all aimed at avoiding direct contact with the vibratory plate, which would cause the lower sensing ball 414 to resonate.

[0055] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
