[0006] In some embodiments, the lead buckle striking device further includes a clamping component, which is spaced apart from the hammering component along the length of the conveyor belt, and is used to remove the lead buckle formed by hammering from the clamping structure.

[0007] In some embodiments, the clamping structure includes: clamping portions, two of which are disposed opposite each other in a first direction; and a driving structure connected to the two clamping portions respectively, so that the two clamping portions move closer to or further away from each other.

[0008] In some embodiments, the clamping structure surrounds and forms a clamping cavity, and the two clamping inner walls of the clamping cavity are disposed opposite each other in a first direction; when the clamping structure is subjected to a vertically downward force, the two clamping inner walls move closer to each other, and when the vertically downward force applied to the clamping structure is removed, the two clamping inner walls move further apart from each other.

[0009] In some embodiments, the clamping structure includes: a clamping plate, two clamping plates being rotatably connected, the rotation axis of the clamping plates being perpendicular to the vertical direction, and the connection position of the two clamping plates being located directly below the hammer body.

[0010] In some embodiments, the clamping structure further includes a torsion spring disposed at the connection position of the two clamping plates. The torsion spring is used to apply an elastic force to the clamping plates, and the elastic force is used to move the free ends of the two clamping plates away from each other. The free ends are the ends of the clamping plates that are away from the connection position.

[0011] In some embodiments, the free end of the clamping plate has a counterweight structure, and the free end is the end of the clamping plate away from the connection position.

[0012] In some embodiments, the clamping structure includes an elastic plate that extends along an arcuate curve.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0025] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0026] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0027] In the following specific embodiments, the lead-tapping device is used in the gold purity test. Before melting the precious metal to be tested, the gold, silver and lead foil to be tested need to be mixed with flux. The flux is placed at the bottom of the gold to be tested, and then the lead-tapping device hammers the mixture, so that the gold and silver to be tested are covered in the flux to form a lead tapping. The structure of the lead-tapping device is illustrated below with reference to the embodiments.

[0028] In some embodiments, such as Figure 1 As shown, the lead buckle-making device 1 includes a hammering assembly 10 and a clamping structure 20. The clamping structure 20 is used to clamp the object to be hammered, which is a mixture of gold to be tested and flux. The clamping structure 20 can be located below the hammering assembly 10. By hammering the mixture held by the clamping structure 20 with the hammering assembly 10, the gold to be tested can be coated inside the flux, thereby forming a lead buckle.

[0029] The hammering assembly 10 includes an operating structure 11 and a hammer body 12. The operating structure 11 enables the hammer body 12 to strike downwards. The operation of the hammer body 12 by the operating structure 11 can be achieved through mechanical transmission, and the force applied to the operating structure 11 can be transmitted to the hammer body 12 to control the hammer body 12 to strike downwards. For example, the operating structure 11 is a pull rod, the end of which is connected to the hammer body 12 via a cable. Pulling the pull rod can transmit the force to the hammer body 12 via the cable and raise the hammer body 12. After releasing the pull rod, the hammer body 12 can strike downwards under its own weight. The operation of the hammer body 12 by the operating structure 11 can also be achieved through an electronic control system. The hammering assembly 10 also includes a drive device for driving the movement of the hammer body 12, and the operating structure 11 is used to control the switching of the drive device. In the operation structure 11, for example, the operating structure 11 is a button, and the driving device is a drive motor. When the drive motor is running, it can control the hammer 12 to reciprocate in the vertical direction. When the drive motor stops running, the hammer 12 stops moving. Pressing the button once can put the drive motor into operation, and pressing the button again can stop the drive motor. At the same time, the distance between the operating structure 11 and the hammer 12 is greater than a first threshold, such as 300 mm. This can be understood as follows: by setting a clamping structure to clamp the mixture, there is no need to manually hold the mixture. At the same time, the distance between the operating structure 11 and the hammer 12 is far enough that the operator's hand does not need to be close to the hammer 12 during the hammer 12 striking the mixture, thereby reducing the risk of the operator's hand being injured by the hammer 12.

[0030] This utility model provides a lead buckle-making device, which includes a hammering assembly and a clamping structure. The clamping structure is used to hold the mixture to be hammered and can be located below the hammering assembly. After the hammering assembly hammers the mixture held by the clamping structure, the mixture can form a lead buckle. Meanwhile, the hammering assembly includes a hammer body for the operator to hammer the mixture, and an operating structure for controlling the hammer body to strike downwards. The distance between the operating structure and the hammer body is greater than a first distance threshold. It can be understood that by setting the clamping structure, the operator does not need to manually hold the mixture to be hammered. At the same time, the distance between the operating structure and the hammer body is far enough to ensure that the distance between the operator's hand and the hammer body is far enough when the hammer body strikes downwards, that is, to ensure that the operator's hand is far away from the hammer body when the hammer body strikes downwards, thereby reducing the risk of the operator's hand being injured.

[0031] In some embodiments, such as Figure 1 As shown, the lead buckle-making device 1 also includes a transmission belt 30. Along the length of the transmission belt 30, multiple clamping structures 20 are spaced apart. The transmission belt 30 can move along its own length, so that each clamping structure 20 moves sequentially to directly below the hammer body 12, thereby allowing the hammer body 12 to sequentially strike the mixture contained in each clamping structure 20. That is, it can realize the function of batch lead buckle making. Specifically, the transmission belt 30 moves intermittently along its own length. When a clamping structure 20 moves to directly below the hammer body 12, the transmission belt 30 stops running for a period of time, so that the clamping structure 20 can stay directly below the hammer body 12, thus providing time for the hammer body 12 to strike the mixture. After the hammer body 12 strikes the mixture and forms a lead buckle, the transmission belt 30 continues to run to carry the lead buckle away from directly below the hammer body 12 and move a new mixture to be struck to directly below the hammer body 12.

[0032] In some embodiments, such as Figure 1 As shown, the lead buckle striking device 1 also includes a clamping assembly 40. Along the length of the conveyor belt 30, the clamping assembly 40 and the hammering assembly 10 are arranged at intervals. The clamping assembly 40 is used to remove the lead buckle formed by hammering from the clamping structure 20. Specifically, along the movement direction of the conveyor belt 30, the hammering assembly 10 and the clamping assembly 40 are arranged at intervals. The mixture to be struck is first transported by the conveyor belt 30 to the area directly below the hammer body 12 so that the mixture to be struck can be struck by the hammer body 12 to form a lead buckle. The formed lead buckle is then moved and transported to the area directly below the clamping assembly 40 so that the clamping assembly 40 can remove the lead buckle from the clamping structure 20 so that the lead buckle can be transferred to the next station of the gold purity testing system.

[0033] It should be noted that the clamping component 40 can be any structure capable of clamping the lead buckle. For example, the clamping component 40 includes a jaw and a lifting structure. The lifting structure can drive the jaw to move up and down vertically towards or away from the lead buckle, allowing the jaw to clamp it. The clamping component 40 can clamp the lead buckle manually. For example, the clamping component 40 has a clamping operation structure. When the lead buckle formed by the hammer is directly below the hammer, this clamping operation structure can control the movement of the lifting structure and the jaw, enabling the jaw to clamp the lead buckle. The clamping component 40 can also clamp the lead buckle automatically. For example, a position sensor is positioned directly below the clamping component 40. When a lead buckle is detected moving directly below the clamping component 40, the clamping component 40 is controlled to clamp the lead buckle.

[0034] In some embodiments, such as Figure 2 As shown, the clamping structure 20 includes a clamping portion 21 and a driving structure 22. The two clamping portions 21 are in a first direction (the first direction is as shown in the figure). Figure 2 As shown by the middle arrow, the drive structure 22 is connected to the two clamping parts respectively, so that the two clamping parts move closer or further apart. Specifically, the drive structure 22 is used to drive the clamping parts 21 to slide in opposite directions in a first direction, so that the two clamping parts 21 can move closer or further apart. When the two clamping parts 21 move closer to each other, the two clamping parts 21 can clamp the mixture to be hammered, and when passing through... Figure 1 During the hammering process of the mixture by the hammer 12, the two clamping parts 21 clamp the mixture, keeping it directly below the hammer 12. This allows the solvent to better coat the outside of the gold being tested, thus improving the quality of the lead buckle formed by the hammering. Figure 1 Before the clamping assembly 40 is directly below it, the two clamping parts 21 are moved away from each other by the drive structure 22, thereby releasing the clamping parts 21 from the lead buckle so that the clamping assembly 40 can remove the lead buckle.

[0035] The drive structure 22 can control the movement of the clamping part 21 in any way. For example, the drive structure 22 is two linear motors, which are respectively connected to the two clamping parts 21 to control the two clamping parts 21 to slide in a first direction. For example, the drive structure 22 may include a rotary motor and a pair of meshing gears. The rotary motor is connected to one gear in the gear pair to form a driving gear, and the other gear forms a driven gear. The driving gear meshes with a first rack structure and the first rack is fixedly connected to one clamping part 21. The driven gear meshes with a second rack structure and the second rack is fixedly connected to the other clamping part 21. The rotary motor can move the two clamping parts 21 closer to each other when it rotates in one direction, and can move the two clamping parts 21 further apart when it rotates in the opposite direction.

[0036] In some embodiments, such as Figure 3 As shown, the clamping structure 20 surrounds and forms a clamping cavity 23, and the two inner walls of the clamping cavity 23 are in a first direction (the first direction is as shown in the figure). Figure 3 As shown by the middle arrow, the clamping structures 20 are positioned opposite each other. When the clamping structure 20 is subjected to a vertically downward force, the clamping structure 20 undergoes elastic deformation or different parts of the clamping structure 20 move relative to each other in a straight line, so that the two inner walls of the clamping cavity 23 move closer to each other, thereby enabling... Figure 1 When the hammer 12 strikes downwards, the two inner walls of the clamping cavity 23 clamp the mixture inside the clamping cavity 23. When the downward vertical force on the clamping structure 20 is removed, the two inner walls of the clamping cavity 23 move away from each other, thereby enabling... Figure 1 After the hammer body strikes downwards, the two inner walls of the clamping cavity 23 move away from each other and return to their initial position, releasing the clamp on the lead buckle formed by the impact. This can be understood as, through... Figure 1 The hammer 12, under the hammering force applied to the clamping structure 20, causes elastic deformation of the clamping structure 20 or relative movement between different parts of the clamping structure 20. This allows the clamping structure 20 to automatically clamp the mixture during hammering without requiring a drive structure, and automatically releases the lead clamp formed after hammering, making the structure of the clamping structure 20 more compact. Simultaneously, since the shape and size changes of the clamping cavity 23 are driven by the hammering force applied by the hammer 12, the shape and size of the clamping cavity 23 can adapt to the position of the hammer 12, thereby reducing the risk of motion interference between the clamping cavity 23 and the hammer 12. The following section combines... Figure 4 and Figure 5 The structure of the clamping structure 20 is described by way of example. Those skilled in the art should understand that the clamping structure 20 can also be other than, Figure 4 and Figure 5 Other structures shown.

[0037] like Figure 4As shown, the first type of clamping structure 20A includes clamping plates 21A. Two clamping plates 21A are rotatably connected, and the rotation axis of the clamping plates 21A is perpendicular to the vertical direction. The ends of the two clamping plates 21A are hinged to form rotating ends. In the thickness direction of the clamping plates 21A, the outer surfaces of the two clamping plates 21A on the same side form two clamping inner walls. During the rotation of the two clamping plates 21A, the two clamping inner walls surround and form... Figure 3 The clamping cavity is located in the middle, and at the same time, the connection position of the two clamping plates 21A is located in the middle. Figure 1 Directly below the hammer 12, it can be understood that when the hammer 12 strikes down, it applies a vertically downward hammering force to the rotating end. Under the action of this hammering force, the two clamping plates 21A rotate around the rotating end, so that the included angle between the two clamping plates 21A decreases, thereby enabling the two clamping plates 21A to clamp the mixture. After the hammer 12 finishes striking, it removes the hammering force from the rotating end, and the clamping plates 21A rotate in the opposite direction around the rotating end under their own weight, so that the included angle between the two clamping plates 21A increases, thereby causing the two clamping plates 21A to loosen the lead buckle formed by the hammering.

[0038] Optional, such as Figure 4 As shown, the first type of clamping structure 20A also includes a torsion spring 22A. The torsion spring 22A is disposed at the connection position of the two clamping plates 21A, that is, the torsion spring 22A is located at the rotating end of the two clamping plates 21A and different parts of the torsion spring 22A are respectively connected to the two clamping plates 21A, so that the torsion spring 22A can apply an elastic rotational force to the two clamping plates 21A. This elastic force is used to move the free ends of the two clamping plates 21A away from each other. The free end is the end opposite to the rotating end, that is, the end away from the connection position. Figure 1 After the hammering force applied by the hammer body 12 to the rotating end is removed, the two clamping plates 21A can rotate in opposite directions under the action of the elastic force, thereby increasing the included angle between the two clamping plates 21A, thus more reliably releasing the lead buckle formed by the hammering.

[0039] Optional, such as Figure 4 As shown, the free end of the clamping plate 21A has a counterweight structure 23A. By setting the counterweight structure at the free end of the clamping plate 21A, the center of mass of the clamping plate 21 can be located further away from the rotating end, thereby generating a larger torque at the rotating end due to the weight of the clamping plate 21A itself. This torque can... Figure 1 After the hammering force applied to the rotating end by the hammer body 12 is removed, the two clamping plates 21A rotate in opposite directions more quickly, so that the included angle between the two clamping plates 21A increases, thereby more reliably releasing the lead buckle formed by the impact.

[0040] like Figure 5As shown, the second type of clamping structure 20B includes an elastic plate 21B that extends along an arc-shaped curve, thereby forming a U-shaped structure. The surface of the elastic plate 21B located within this U-shaped structure surrounds and forms... Figure 3 The clamping cavity 23 in the U-shaped structure has two opposing surfaces forming two clamping inner walls. Figure 1 When the hammer 12 applies a hammering force to the U-shaped structure, the elastic plate 21B undergoes elastic deformation to bring the two clamping inner walls closer together, thereby clamping the mixture. After the hammer 12 removes the hammering force on the elastic plate 21B, the elastic plate 21B rebounds under its own elasticity, thereby causing the two clamping walls to move away from each other and loosening the clamping of the lead buckle formed by the hammering.

[0041] In some embodiments, combined with Figure 1 and Figure 6 The hammering assembly 10 also includes a locking structure 13 and an unlocking structure 14. The locking structure 13 is used to lock the vertical movement of the hammer body 12. That is, when the locking structure 14 locks the hammer body 12, the hammer body 12 cannot move vertically and thus cannot perform the hammering function. By setting the locking structure 13, the risk of the hammer body 12 falling accidentally can be reduced, thereby further reducing the risk of the operator's hand being injured by the hammer. The locking structure 13 is used to release the lock on the hammer body 12, so that the hammer body 12 can move vertically and thus perform the hammering function. The locking and unlocking of the hammer body 12 by the locking structure 13 and the unlocking structure 14 can be achieved in different ways. Optionally, the locking structure 13 locks the hammer body 12 through a mechanical structure, and the unlocking structure 14 releases the lock on the hammer body 12 by displacing the locking structure 13. For example, the surface of the hammer 12 has a locking groove, the depth direction of which is perpendicular to the vertical direction. The locking structure 13 is a locking block that can extend into or move out of the locking groove along its depth direction. The unlocking structure 14 is used to drive the locking block to extend into or move out of the locking groove. When the locking block is extended into the locking groove, the vertical movement of the hammer 12 is locked. When the locking block is moved out of the locking groove, the vertical movement of the hammer 12 is unlocked. Optionally, the locking structure 13 locks the hammer 12 by electromagnetic force, and the unlocking structure 14 uses an electronic control system to control the locking structure 13 to release the lock on the hammer 12. For example, the locking structure 13 is an electromagnet, and the unlocking structure 14 can control the energization and de-energization of the electromagnet. When the electromagnet is energized, the vertical movement of the hammer is locked. When the electromagnet is de-energized, the vertical movement of the hammer 12 is unlocked.

[0042] Meanwhile, the distance between the unlocking structure 14 and the hammer 12 is greater than the first threshold, and the distance between the unlocking structure 14 and the operating structure 11 is greater than the second distance threshold. This can be understood as follows: if the hammer 12 is to strike, both the operating structure 11 and the unlocking structure 14 need to be operated simultaneously. Both the operating structure 11 and the unlocking structure 14 are located far enough away from the hammer 12, and the distance between them is also far enough to prevent the operator from operating both the operating structure 11 and the unlocking structure 14 simultaneously with one hand. That is, the operator needs to operate both the operating structure 11 and the unlocking structure 14 separately with both hands so that both of the operator's hands are located far away from the hammer 12 when the hammer 12 strikes, further reducing the risk of the operator's hands being injured by the hammer. The second distance threshold can be understood as the maximum length of the palm of 95% of adult males. For example, the second distance threshold is 210 mm.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
