Description

Technical Field

[0001] The utility model relates to the technical field of magnetic block batch detection, in particular to a magnetic block rejecting device for magnetic block batch detection equipment. Background Art

[0002] Due to their reusable nature, magnets are widely used in consumer applications such as home entertainment, outdoor adventures, and educational toys. The most critical process in magnet production is magnetizing the bulk magnetic material. Consumer magnets are relatively small, and the dimensional accuracy of mass-produced magnets is often inconsistent. This results in some magnetic material failing to reach full saturation during magnetization, leading to magnetic flux leakage. This manifests as insufficient magnetic attraction. Therefore, magnetic testing is a crucial step in magnet production.

[0003] Existing magnetic detection solutions, such as those described in patent document CN113311371A, place a magnet chain consisting of multiple magnetic blocks within a magnet chain slot on a magnet chain mounting platform. A movable guide rail drives the platform, allowing all the magnetic blocks in the chain to pass through a magnetic field sensor for magnetic detection. However, because existing technologies use grippers to remove magnetic blocks that fail magnetic detection, accurate identification of each individual magnetic block is required, which can be prone to errors. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a magnetic block rejecting device in a magnetic block batch detection device which can accurately reject magnetic blocks that fail magnetic detection.

[0005] In order to solve the above technical problems, the utility model provides a magnetic block rejection device for a magnetic block batch detection equipment. The magnetic block batch detection equipment includes a horizontal transmission channel for the magnetic blocks to be detected to pass through. The magnetic block rejection device is arranged at the end of the transmission channel. The magnetic block rejection device includes a resistance member and a lifting device for driving the resistance member to move up and down. A section of the transmission channel directly below the resistance member is hollowed out. The resistance member is driven by the lifting device to move downward until it abuts against the magnetic block on the transmission channel. The resistance member continues to move downward until the magnetic block detaches from the continuous batch of magnetic blocks. The detached magnetic block falls from the hollow part of the transmission channel and is rejected.

[0006] Furthermore, the resisting member includes a clamping jaw and a cylinder for driving the clamping jaw to open and close. When the clamping jaw is opened a short distance, the resisting member moves downward to remove the magnetic block.

[0007] Furthermore, the clamping jaw has two clamping parts, and the contact surfaces of the two clamping parts are respectively provided with gaskets.

[0008] Furthermore, the cylinder is a pneumatic finger cylinder with a model number of HFK40_CL.

[0009] Furthermore, the travel speed of the lifting device is greater than 1 m / s.

[0010] Furthermore, the magnetic block removal device also includes a mounting panel and a slide rail device mounted on a side of the mounting panel, and the lifting device is mounted on the slide rail device so as to achieve lateral movement to align with the hollow portion of the transmission channel.

[0011] The utility model has the following beneficial effects: the magnetic block rejecting device of the magnetic block batch detection equipment comprises a horizontal transmission channel for the magnetic blocks to be detected to pass through, the magnetic block rejecting device is arranged at the end of the transmission channel, the magnetic block rejecting device comprises a resistance member and a lifting device for driving the resistance member to move up and down, a section of the transmission channel directly below the resistance member is hollowed out, the resistance member moves downward under the drive of the lifting device until it abuts against the magnetic block on the transmission channel, the resistance member continues to move downward until the corresponding unqualified magnetic block is detached from the batch of magnetic blocks together with multiple magnetic blocks before and after it, the detached magnetic block falls from the hollow part of the transmission channel and is rejected, thereby being able to accurately reject the unqualified magnetic blocks detected by magnetic detection.

[0016] The present invention is further described in detail below in conjunction with specific embodiments.

[0017] The magnetic block batch detection device of this embodiment is as follows Figure 1 and 2 As shown, it includes a horizontal transmission channel for the magnetic blocks to be detected to pass through, as well as a controller and a loading and shaping conveying device 1, a detection orientation adjustment device 2, a unloading and pressing conveying device 3 and a magnetic block rejection device 4 which are arranged in sequence along the magnetic block transmission direction beside the magnetic block transmission channel. These devices are respectively communicated with the controller of the magnetic block batch detection equipment.

[0018] like Figure 3As shown, batches of magnetic blocks C are placed into a transmission channel from the starting point S of the magnetic block batch inspection equipment in an engaged state. A removable vertical baffle is installed at the head end of the transmission channel. Before inspection, the vertical baffle is removed to insert the magnetic blocks to be inspected. After the batch of magnetic blocks to be inspected is placed in the first section of the transmission channel, the vertical baffle is installed to hold the last magnetic block in place, ensuring a compact queue of magnetic blocks. The loading and shaping conveyor 1 is used to limit and transport the batch of magnetic blocks at the top and sides, allowing multiple magnetic blocks to continuously pass through the magnetic detector in the inspection orientation adjustment device 2 in a neatly connected manner. The magnetic detector detects the magnetism of each magnetic block and transmits the detected magnetic data to the controller. The controller is also communicatively connected to the display 0, which displays the magnetic data. The unloading and compacting conveyor 3 applies pressure to the passing magnetic block queue from both sides to ensure a compact connection between adjacent magnetic blocks. The controller identifies unqualified magnetic blocks from the received magnetic data according to a preset program and sends an in-place signal indicating the unqualified magnetic blocks to the magnetic block rejection device 4. The magnetic block rejection device 4 is designed to operate in response to received in-place signals, removing the corresponding magnetic block from the continuous batch of magnetic blocks. A baffle is positioned a short distance away from the end of the transmission channel, tilted in the direction of the transmission channel. Magnetic blocks that remain in the batch, considered qualified, are removed from the transmission channel at the end E of the magnetic block batch inspection equipment and fall due to gravity or are caught by the baffle, dropping into a discharge chute below the end of the transmission channel.

[0019] The following is a detailed description of the working process of each device of the magnetic block batch detection equipment.

[0020] like Figure 3 As shown, the transmission channel is specifically a U-shaped structure consisting of two interlocking left and right panels 24 and 25. One of the panels is a horizontal bottom panel that supports the magnetic block to be detected, while the other is an inverted L-shaped structure. The entire transmission channel is composed of multiple sets of two interlocking panels, each equipped with a transverse drive device to move the two panels apart or together, thereby adjusting the width of the transmission channel to accommodate the width of the magnetic block.

[0021] like Figure 4 As shown, the final section of the batch magnetic block inspection equipment is equipped with a magnetic block rejection device 4. This device includes a resisting member and a lifting device for driving the resisting member up and down. A section of the transmission channel directly below the resisting member is hollowed out. Driven by the lifting device, the resisting member moves downward until it contacts the magnetic block on the transmission channel. The resisting member continues to move downward until the magnetic block detaches from the continuous batch of magnetic blocks. The detached magnetic block falls through the hollow portion of the transmission channel and is rejected. The lifting device has a travel speed of greater than 1m / s. The high travel speed of the lifting device provides a greater impulse to disconnect the continuously attracted magnetic blocks.

[0022] like Figure 4As shown, the resistance member includes a clamping jaw 43 and a cylinder 42 for driving the clamping jaw 43 to open and close. The cylinder 42 is a pneumatic finger cylinder with model HFK40_CL. The clamping jaw 43 has two clamping members, and the contact surfaces of the two clamping members are respectively provided with gaskets 44. When the clamping jaw 43 is opened a short distance, the resistance member moves downward to remove the magnetic block, so that the contact between the resistance member and the top of the magnetic block is not the entire surface but a discontinuous line segment, which can provide intermittent impact force to disconnect the continuously attracted magnetic block.

[0023] The magnetic block removal device 4 further includes a mounting panel 41 and a slide rail device mounted on the side of the mounting panel. The lifting device is mounted on the slide rail device so as to achieve lateral movement to align with the hollow portion of the transmission channel.

[0024] The above is only an embodiment of the invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention and still fall within the scope of patent protection.
