Description

Technical Field

[0001] This application relates to the field of transmission mechanism technology, and in particular to a multi-directional relay transmission device and chip testing equipment. Background Technology

[0002] During the manufacturing, assembly, or testing of chip products, transmission lines are required for transportation and transfer. Taking chip testing as an example, several chips are loaded into a fixture, which is transferred between various workstations via transmission lines to transport the chips to the testing station, and then the tested chips are transferred out again.

[0003] Some equipment has its inlet and outlet points located at the same location. This is often due to requirements such as interfacing with external transmission lines or the equipment's own sealing requirements, making it unsuitable to have too many inlet and outlet points. Typically, such equipment uses a transfer transmission structure at the same location for both inlet and outlet transfer. Existing transfer transmission structures generally arrange the inlet and outlet transmission lines in parallel, one for each. This structure has a relatively simple transmission mode, limited transport efficiency, and occupies a large amount of space. Utility Model Content

[0004] One objective of this invention is to provide a multi-directional relay transmission device that can offer more transmission modes and improve transmission efficiency.

[0005] Another objective of this invention is to adapt to target devices of more sizes.

[0006] An embodiment of this utility model provides a multi-directional relay transmission device, comprising: The moving mechanism can reciprocate the target device along the first horizontal direction; The lifting motion module includes a lifting platform and a first transmission mechanism and a second transmission mechanism disposed on the lifting platform; the lifting platform can synchronously drive the first transmission mechanism and the second transmission mechanism to lift and lower, and both the first transmission mechanism and the second transmission mechanism can reciprocate to transport the target device along a second horizontal direction, which is perpendicular to the first horizontal direction. The lifting platform is used to move the first transmission mechanism and the second transmission mechanism to a first working height; or to move the first transmission mechanism and the second transmission mechanism to a second working height; The first working height is the height at which the transmission surface formed by the first transmission mechanism and the second transmission mechanism is lower than the transmission surface of the moving mechanism; The second working height is the height at which the transmission surface formed by the first transmission mechanism and the second transmission mechanism is higher than the transmission surface of the moving mechanism.

[0007] Optionally, the multi-directional transfer device further includes a limiting component, which includes two side limiting mechanisms arranged at intervals on both sides of the lifting platform along a second horizontal direction. The side limiting mechanism includes a side limiting member and a first rotation drive mechanism. The first horizontal axis extends along the first horizontal direction. The first rotation drive mechanism is used to drive the side limiting member to rotate around the first horizontal axis so that the side limiting member is in a second direction limiting state and a non-second direction limiting state. The second directional limiting state is the state in which the side limiting member and the target device are in a limiting engagement, thereby limiting the target device in the second horizontal direction; The non-second direction limiting state is the state in which the side limiting member and the target device are not limited, thereby releasing the limitation of the target device in the second horizontal direction.

[0008] Optionally, the multi-directional transfer device further includes two side supports, each of which is used to mount one of the first rotation drive mechanisms.

[0009] Optionally, a first guide roller assembly is also connected to the side bracket. The first guide roller assembly is located on the side of the side limiting member away from the lifting motion module, and the first guide roller assembly includes a plurality of first rollers arranged vertically along the axis. The plurality of first rollers together form a first channel with a width matching the width of the target device.

[0010] Optionally, the side support is further connected to a plurality of second rollers, each of which is arranged axially along the first horizontal direction and at the same height, and each of the second rollers is used to support the target device and to transport the target device along the second horizontal direction.

[0011] Optionally, the limiting component further includes a first limiting mechanism and a second limiting mechanism arranged at intervals on both sides of the moving mechanism along a first horizontal direction; The first limiting mechanism includes a first limiting member, which is used to limit and cooperate with the target device. The second limiting mechanism includes a second limiting member and a second rotation driving mechanism. The second rotation driving mechanism is used to drive the second limiting member to rotate so that the second limiting member is in a first direction limiting state and a non-first direction limiting state. The first directional limiting state is the state in which the second limiting member and the first limiting member respectively limit and cooperate with the target device, thereby restricting the target device in the first horizontal direction; The non-first direction limiting state is a state in which at least the second limiting member and the target device are not in a limiting engagement, thereby releasing the limitation of the target device in the first horizontal direction.

[0012] Optionally, both the first transmission mechanism and the second transmission mechanism include multiple axle wheel assemblies and a third rotation drive mechanism. The third rotation drive mechanism is connected to one of the axle wheel assemblies, and the axle wheel assemblies are connected to each other by a synchronous belt. Each axle wheel assembly is supported on the lifting platform.

[0013] Optionally, the lifting platform includes a platform, a guide mechanism, and a lifting mechanism for driving the platform to rise and fall; The guiding mechanism includes a fixed plate, a support plate, and a sliding assembly; the sliding assembly is located between the fixed plate and the support plate, and the support plate is connected to the table surface; The lifting mechanism includes a connecting plate and a lifting drive source for driving the connecting plate to rise and fall, and the connecting plate is connected to the support plate.

[0014] Optionally, the moving mechanism includes at least two conveyor belt assemblies and a fourth rotation drive mechanism, the fourth rotation drive mechanism being connected to one of the conveyor belt assemblies, adjacent conveyor belt assemblies being connected via a synchronous shaft, and the conveyor belt of each conveyor belt assembly being arranged around the table surface.

[0015] In particular, this application also provides a chip testing device, including the multi-directional relay transmission device described in any of the above claims.

[0016] According to a first aspect of the present invention, a transmission device with multi-directional transmission function is provided. By controlling the first transmission mechanism and the second transmission mechanism to rise and fall synchronously through a lifting platform, different transmission mechanisms can be switched to transmit the target device in different directions. When the first transmission mechanism and the second transmission mechanism are the currently effective transmission mechanisms, the feeding and discharging in the second horizontal direction can be realized, or when the moving mechanism is the currently effective transmission mechanism, the feeding and discharging in the first horizontal direction can be realized.

[0017] Furthermore, when the first and second transmission mechanisms are driven separately, reverse alternation or reverse synchronization of feeding and discharging can be achieved. Multiple transmission paths can be realized through the cooperation of the moving mechanism, the lifting platform, the first transmission mechanism, and the second transmission mechanism, thereby adapting to more transmission conditions and target device sizes.

[0018] According to a second aspect of this invention, the side limiting member and the second limiting member are configured to be rotatable, thereby creating a height that may or may not obstruct the target device, thus achieving a basic limiting function. Furthermore, this method of adjusting the height of the limiting members by rotation can create different limiting dimensions, thereby accommodating target devices of a wider range of sizes.

[0019] According to a third aspect of this utility model, the arrangement of the first guide roller group can guide and limit the target device when feeding and discharging along the second horizontal direction, and the arrangement of the second guide roller group can guide and limit the target device when feeding and discharging along the first horizontal direction. Furthermore, the arrangement of multiple first rollers, multiple second rollers, and multiple third rollers can reduce the friction force during the transmission of the target device, thereby reducing transmission resistance and noise.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the spirit of this disclosure.

[0024] It should be understood that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

The descriptions of "first," "second," etc., appearing in this application's embodiments are merely illustrative and for distinguishing the described objects; they have no order and do not indicate a specific limitation on the number in this application's embodiments, nor do they constitute any limitation on the embodiments of this application.

[0026] Figure 1 This is a schematic diagram of the structure of a multi-directional relay transmission device 100 according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of a multi-directional relay transmission device 100 (partial moving components are hidden) according to an embodiment of the present invention.

[0027] like Figure 1As shown, in one embodiment, the multi-directional transfer device 100 includes a moving mechanism 10 and a lifting motion module. The moving mechanism 10 can reciprocate to transport a target device along a first horizontal direction. The target device is the device to be transported, such as a fixture carrying a chip array, or a single target object or a target object set on a corresponding fixture, without limitation. The lifting motion module includes a lifting platform 20 and a first transmission mechanism 30 and a second transmission mechanism 40 disposed on the lifting platform 20; the lifting platform 20 can synchronously drive the first transmission mechanism 30 and the second transmission mechanism 40 to rise and fall. Both the first transmission mechanism 30 and the second transmission mechanism 40 can reciprocate to transport the target device along a second horizontal direction, which is perpendicular to the first horizontal direction. The lifting platform 20 is used to move the first transmission mechanism 30 and the second transmission mechanism 40 to a first working height, and the lifting platform 20 is also used to move the first transmission mechanism 30 and the second transmission mechanism 40 to a second working height. The first working height is the height at which the transmission surface formed by the first transmission mechanism 30 and the second transmission mechanism 40 is lower than the height of the transmission surface of the moving mechanism 10, and the second working height is the height at which the transmission surface formed by the first transmission mechanism 30 and the second transmission mechanism 40 is higher than the height of the transmission surface of the moving mechanism 10.

[0028] In this embodiment, the first transmission mechanism 30 and the second transmission mechanism 40 can be driven by a single driving source and move synchronously, or they can be driven by two separate driving sources; no limitation is made here. When the first transmission mechanism 30 and the second transmission mechanism 40 move synchronously, they can form a motion state of transmission along the second horizontal direction or transmission in the opposite direction of the second horizontal direction. When the first transmission mechanism 30 and the second transmission mechanism 40 are driven by two driving sources respectively, they can each form different transmission directions. The first transmission mechanism 30 and the second transmission mechanism 40 can form a reverse alternating motion or a reverse synchronous motion mode: In the reverse alternating motion mode, the first transmission mechanism 30 transmits the target device on one side of the second horizontal direction, and then the second transmission mechanism 40 transmits the target device on the other side of the second horizontal direction, and so on alternately; In the reverse synchronous motion mode, the first transmission mechanism 30 and the second transmission mechanism 40 can simultaneously transmit the target device to both sides of the second horizontal direction. At this time, the area of ​​the target device needs to be small so that the two target devices can be laid flat on the surface of the moving mechanism 10 along the second horizontal direction at the same time. When the lifting platform 20 drives the first transmission mechanism 30 and the second transmission mechanism 40 to move to the second working height, the two target devices can fall onto the transmission surface of the first transmission mechanism 30 and the second transmission mechanism 40 respectively, so that the first transmission mechanism 30 and the second transmission mechanism 40 can simultaneously transmit the target devices to opposite sides.

[0029] This embodiment provides a transmission device with multi-directional transmission function. The lifting platform 20 controls the first transmission mechanism 30 and the second transmission mechanism 40 to lift synchronously, thereby switching between different transport mechanisms to transport the target device in different directions. The different transport mechanisms can be understood as the first transmission mechanism 30 and the second transmission mechanism 40 as the currently effective transport mechanism, which can realize the feeding and discharging of materials in the second horizontal direction, or the moving mechanism 10 as the currently effective transport mechanism, which can realize the feeding and discharging of materials in the first horizontal direction.

[0030] Furthermore, when the first transmission mechanism 30 and the second transmission mechanism 40 are driven separately, reverse alternating feeding and discharging or reverse synchronous feeding and discharging can be achieved. That is, material can be discharged from one side in the second horizontal direction and then discharged from the other side, or material can be discharged from both sides simultaneously in the first horizontal direction. Of course, the first transmission mechanism 30 and the second transmission mechanism 40 can also be driven separately to form a motion state where the first transmission mechanism 30 and the second transmission mechanism 40 are driven synchronously. That is, multiple transmission paths can be realized through the cooperation of the moving mechanism 10, the lifting platform 20, the first transmission mechanism 30 and the second transmission mechanism 40, thereby adapting to more transmission conditions and target device sizes.

[0031] Further in one embodiment, such as Figure 1 As shown, the multi-directional transfer device 100 also includes a limiting assembly. The limiting assembly includes two side limiting mechanisms 50 arranged at intervals along the second horizontal direction and located on both sides of the lifting platform 20. The side limiting mechanism 50 includes a side limiting member 51 and a first rotation drive mechanism 52. The first rotation drive mechanism 52 is used to drive the side limiting member 51 to rotate around a first horizontal axis. The first horizontal axis extends along the first horizontal direction so that the side limiting member 51 is in a second direction limiting state and a non-second direction limiting state. The second direction limiting state is the state in which the side limiting member 51 is in a limiting engagement with the target device, thereby restricting the target device in the second horizontal direction. The non-second direction limiting state is the state in which the side limiting member 51 is not in a limiting engagement with the target device, thereby releasing the restriction of the target device in the second horizontal direction. The first rotation drive mechanism 52 of this embodiment is disposed on the side bracket 91 and includes a first cylinder 521 and a first gear and rack mechanism 522. The first cylinder 521 is used to drive the rack of the first gear and rack mechanism 522 to move along the second horizontal direction. The gear of the first gear and rack mechanism 522 is supported on the side bracket 91 by a support shaft 523, and the support shaft 523 is fixedly connected to the side limiting member 51.

[0032] When the first rotation drive mechanism 52 drives the side limiting member 51 to rotate to a vertical position, the side limiting member 51 can block and limit the target device on one side. When both side limiting members 51 are in a vertical position, the target device is restricted in the second horizontal direction. When the first rotation drive mechanism 52 drives the side limiting member 51 to a horizontal position, the side limiting member 51 is no longer blocking the target device, thereby releasing the restriction on the target device in the second horizontal direction.

[0033] Furthermore, the limiting assembly also includes a first limiting mechanism 70 and a second limiting mechanism 80 arranged at intervals along the first horizontal direction on both sides of the moving mechanism 10. The first limiting mechanism 70 includes a first limiting member 71, which is used to limit and cooperate with the target device. The second limiting mechanism 80 includes a second limiting member 81 and a second rotation driving mechanism 82, which is used to drive the second limiting member 81 to rotate, so that the second limiting member 81 is in a first-direction limiting state and a non-first-direction limiting state. The first-direction limiting state is when the second limiting member 81 and the first limiting member 71 are respectively limited and cooperated with the target device, thereby restricting the target device in the first horizontal direction. The non-first-direction limiting state is when at least the second limiting member 81 is not limited and cooperated with the target device, thereby releasing the restriction of the target device in the first horizontal direction. In this embodiment, the first limiting member 71 is a fixed member, fixedly installed on the front end bracket 92. In other embodiments, the first limiting member 71 can also be set as a rotating member or a lifting member to form different limiting heights. In this embodiment, the second rotation drive mechanism 82 adopts a structure similar to that of the first rotation drive mechanism 52, and will not be described again here. In other embodiments not shown, the first rotation drive mechanism 52 and the second rotation drive mechanism 82 can also be other forms of drive structures, such as a motor, a combination of a motor and a reduction mechanism, etc., and are not limited here.

[0034] The limiting principle of the second limiting mechanism 80 is similar to that of the side limiting mechanism 50, and will not be described in detail here.

[0035] In actual operation, when the target device is moved from the outside by the moving mechanism 10 toward the first limiting mechanism 70, both side limiting members 51 are in a vertical state, thus restricting the position of the target device in the second horizontal direction. When the target device moves to the target position, the second limiting member 81 rotates to a vertical state to restrict the target device between the first limiting member 71 and the second limiting member 81, that is, restricting the position of the target device in the first horizontal direction. When it is necessary to move the target device in the second horizontal direction for discharge, the lifting platform 20 drives the first transmission mechanism 30 and the second transmission mechanism 40 to rise to the second working height, and then controls one side limiting member 51 to rotate to a horizontal state. The first transmission mechanism 30 and the second transmission mechanism 40 then drive the target device to discharge along the second horizontal direction. Of course, when the target device enters from one side of the second horizontal direction of the multi-directional transfer transmission device 100, the process of transmission in the first horizontal direction is the reverse of the above process, and the principle is similar, so it will not be described again here.

[0036] In this embodiment, the side limiting member 51 and the second limiting member 81 are configured to be rotatable, thereby allowing for a height that may or may not obstruct the target device, achieving a basic limiting function for different transportation conditions of the target device. Furthermore, this method of adjusting the height of the limiting members by rotation can create different limiting dimensions (for example, the distance between the two side limiting members 51 varies at different rotation angles), thus accommodating target devices of more sizes.

[0037] In one embodiment, the side limiting member 51, the first limiting member 71, and the second limiting member 81 are all configured as elongated strips to adapt to the edge dimensions of the target device, thereby stably stopping the target device.

[0038] In another embodiment, such as Figure 1As shown, a first guide roller assembly is also connected to the side bracket 91. The first guide roller assembly is located on the side of the side limiting member 51 away from the lifting motion module, and includes multiple first rollers 61 arranged vertically along the axis. The multiple first rollers 61 together form a first channel with a width matching the width of the target device. In this embodiment, the number of first rollers 61 is 2, and the two first rollers 61 are arranged at intervals along the first horizontal direction, forming the aforementioned first channel between them. In other embodiments not shown, the number of first rollers 61 can be more, for example, two rows of first roller assemblies arranged along the first horizontal direction, each row of first roller assemblies including at least 2 first rollers 61. In this way, when the target device enters or exits the lifting motion module along the second horizontal direction, the target device can pass through the first channel. A multiple second roller 62 is also connected to the side bracket 91, and the axis of each second roller 62 is arranged along the first horizontal direction and at the same height. Each second roller 62 is used to support the target device and to move the target device along the second horizontal direction. Furthermore, the side bracket 91 is also provided with a second guide roller assembly. The second guide roller assembly is located on the side of the second limiting member 81 away from the lifting motion module, and includes multiple third rollers 63 arranged vertically along the axis. The multiple third rollers 63 together form a second channel with a width matching the length of the target device. Like the first guide roller assembly, the second guide roller assembly may include at least two third rollers 63, which will not be described in detail here. In this way, when the target device enters or exits the lifting motion module along the first horizontal direction, the target device can pass through the second channel.

[0039] In this embodiment, the first guide roller group can guide and limit the target device when feeding and discharging in the second horizontal direction, and the second guide roller group can guide and limit the target device when feeding and discharging in the first horizontal direction. Furthermore, the arrangement of multiple first rollers 61, multiple second rollers 62 and multiple third rollers 63 can reduce the friction during the transmission of the target device and reduce the transmission resistance.

[0040] Figure 3 This is a schematic diagram of the structure of a multi-directional transfer device 100 according to an embodiment of the present invention at the lifting platform 20. In one embodiment, as... Figure 3As shown, the lifting platform 20 includes a platform 21, a guide mechanism 22, and a lifting mechanism 23 for driving the platform 21 to rise and fall. The guide mechanism 22 includes a fixed plate 221, a support plate 222, and a sliding assembly 223. The fixed end of the sliding assembly 223 is fixedly connected to the fixed plate 221. One end of the support plate 222 is connected to the platform 21, and the other end of the support plate 222 is connected to the sliding end of the sliding assembly 223. The lifting mechanism 23 includes a connecting plate 231 and a lifting drive source 232 for driving the connecting plate 231 to rise and fall. The connecting plate 231 is connected to the support plate 222. The lifting drive source 232 can be a motor, cylinder, hydraulic lifting rod, or other components, and is not limited here. Furthermore, the fixed plate 221 is provided with limit holes 224, and the two ends of the connecting plate 231 pass through the two limit holes 224 on the two fixed plates and are fixedly connected to the support plates 222 on both sides; during the process of the lifting mechanism 23 driving the platform 21 to rise and fall, the connecting plate 231 can reciprocate within the limit holes 224, thereby achieving the limitation of the lifting height of the platform 21.

[0041] Furthermore, such as Figure 2 As shown, both the first transmission mechanism 30 and the second transmission mechanism 40 include multiple axle wheel assemblies 31 and a third rotation drive mechanism 32. The third rotation drive mechanism 32 is driveably connected to one axle wheel assembly 31. Each axle wheel assembly 31 is connected to the others via a synchronous belt 33, and each axle wheel assembly 31 is supported on the platform 21. In this embodiment, each axle wheel assembly 31 of the first transmission mechanism 30 and the second transmission mechanism 40 rotates synchronously. Here, the axle wheel assembly 31 refers to a component including a rotating shaft 311 and third rollers 312 fixedly disposed at both ends of the rotating shaft 311. Adjacent rotating shafts 311 are connected to each other via synchronous belts 33 to achieve synchronous rotation. In this embodiment, the third rotation drive mechanism 32 includes a motor 321 and a belt transmission mechanism 322. One end of the belt transmission mechanism 322 is connected to the motor 321, and the other end is connected to a rotating shaft 311, so that the rotating shaft 311 is driven to rotate through the transmission cooperation of the motor 321 and the belt transmission mechanism 322.

[0042] Furthermore, the moving mechanism 10 includes at least two conveyor belt assemblies 11 and a fourth rotary drive mechanism 12 for driving the movement of the conveyor belt assemblies 11. Adjacent conveyor belt assemblies 11 are connected by a synchronous shaft 13. Each conveyor belt assembly 11 includes two pulleys and a conveyor belt wound around the two pulleys. The conveyor belt is arranged around the platform 21, meaning that the conveyor belt has a portion above the platform 21 and a portion below the platform 21. In this embodiment, the fourth rotary drive mechanism 12 also employs a motor and belt transmission mechanism drive structure, which will not be described in detail here. Of course, in other embodiments not shown, the third rotary drive mechanism 32 and the fourth rotary drive mechanism 12 can also be other structures, such as commonly used rotary drive structures like motors and gear assemblies, which are not limited here.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
