[0022] The following is as follows Figures 1 to 6 This invention describes an electronic pen clamping and positioning mechanism according to an embodiment of the present invention.
[0023] like Figure 1 and Figure 2As shown, an electronic pen clamping and positioning mechanism according to an embodiment of the present invention includes a carrier plate 100, a drive module 200, and a clamping module 300. At least one product placement groove 110 is formed on the upper surface of the carrier plate 100. A first groove 111 is formed at the bottom of the product placement groove 110. A magnetic element 120 is fixedly disposed within the first groove 111. The drive module 200 includes a first moving component 210 and a second moving component 220 disposed around the periphery of the carrier plate 100. The second moving component 220 is disposed at the transmission point of the first moving component 210. The moving end of the clamping module 300 includes a clamping member 310 and a transmission structure 320. One end of the transmission structure 320 is connected to the transmission end of the second moving component 220, and the other end of the transmission structure 320 is connected to the clamping member 310. The clamping member 310 is located above the product placement slot 110. The first moving component 210 is adapted to drive the second moving component 220, the transmission structure 320 and the clamping member 310 to move in the front-back direction. The second moving component 220 is adapted to drive the transmission structure 320 and the clamping member 310 to clamp or release the product to be tested in the up-down direction.
[0024] When the mechanism is in use, the clamping module 300 is located above and behind the product placement slot 110, which facilitates the placement of the product to be tested into the product placement slot 110. After the product to be tested is placed into the product placement slot 110, it is attracted by the magnetic attraction element 120 in the first groove 111 and can be placed relatively stably in the product placement slot 110. At this time, the first moving component 210 of the drive module 200 can drive the second moving component 220, the transmission structure 320 and the clamping component 310 to move in the back and forth direction. When the second moving component 220 drives the transmission structure 320 and the clamping component 310 to move down, the clamping component 310 can contact the product to be tested and cooperate with the product placement slot 110 to ensure the flatness of the product to be tested in the product placement slot 110, so that its axial or radial direction is accurately aligned with the processing reference surface, thereby improving the quality and reliability of subsequent processes.
[0025] It is understandable that, such as Figure 3 and Figure 4 As shown, the carrier plate 100 is also provided with a third groove 140. The setting of the third groove 140 can facilitate the tight fit between the carrier plate 100 and the transmission structure 320, so that the clamping member 310 can better enter the carrier plate 100 and cooperate with the product placement groove 110.
[0026] It is understandable that when the product under test is a cylindrical elongated shape (e.g., an electronic pen), the first moving component 210 can, through a preset position, drive the second moving component 220 and the clamping module 300 along the extension direction of the product under test (i.e., Figure 3The device moves and stops multiple times in the forward and backward direction. When it stops, the second moving component 220 can drive the clamping component 310 of the clamping module 300 to press down on the product to be tested. This allows the clamping component 310 of the clamping module 300 to clamp and position the product to be tested multiple times in the middle section of the product's extension direction. This ensures the flatness of the product to be tested in the product placement groove 110 and makes it accurately aligned with the processing reference surface in the axial or radial direction, thereby improving the quality and reliability of subsequent processes.
[0027] It is understood that multiple first grooves 111 can be provided, and each first groove 111 can contain a magnetic element 120. It is also understood that the first groove 111 can be a through groove. When the first groove 111 is a through groove, the carrier plate 100 is also provided with a connecting plate 150. The connecting plate 150 can cover the bottom groove opening of the first groove 111. The magnetic element 120 is disposed on the upper end face of the connecting plate 150 and located within the first groove 111. This mating design facilitates the installation and replacement of the magnetic element 120.
[0028] It is understandable that, such as Figure 3 As shown, the drive module 200 also includes a first limit sensor 230 and a second limit sensor 240 arranged front and rear. The first moving component 210 is provided with a limit member 250. Both the first limit sensor 230 and the second limit sensor 240 have slot-shaped sensing areas suitable for accommodating the limit member 250. The first moving component 210 can drive the limit member 250 to move in the front-back direction and enter the sensing area of the first limit sensor 230 or the second limit sensor 240. When the limit member 250 enters the sensing area of the first limit sensor 230 or the second limit sensor 240, the first limit sensor 230 or the second limit sensor 240 can send a signal to the host computer, thereby controlling the front-back movement of the moving end of the first moving component 210 to prevent exceeding the travel limit.
[0029] In some specific embodiments of this utility model, an inspection module 400 is also included. The inspection module 400 includes at least one set of through-beam photoelectric sensors. The transmitter of the through-beam photoelectric sensor is located on one side of the product placement slot 110, and the receiver of the through-beam photoelectric sensor is located on the other side of the product placement slot 110.
[0030] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the inspection module 400 includes two sets of through-beam photoelectric sensors. The two sets of sensors are arranged side by side along the front-to-back direction, forming two parallel detection lines above the product placement slot 110. By detecting whether the product to be tested simultaneously blocks the two detection lines, it can be determined whether it is placed flat in the product placement slot 110, ensuring that its axial or radial direction is precisely aligned with the processing reference surface.
[0031] Understandably, when the inspection module 400 includes two sets of through-beam photoelectric sensors, the clamping module 300 clamps the product to be tested between the two sets of sensors, thereby quickly ensuring the flatness of the product to be tested.
[0032] In some specific embodiments of this utility model, the transmission structure 320 includes a first connecting member 321, a fixing member 322, a second connecting member 323, and a floating member 324. The first connecting member 321 is connected to the transmission end of the second moving component 220. The fixing member 322 is provided on the lower end face of the first connecting member 321. The second connecting member 323 is provided on the fixing member 322. One end of the second connecting member 323 is movably connected to the fixing member 322, and the other end of the second connecting member 323 is fixedly connected to the floating member 324. An elastic body 325 is sleeved on the second connecting member 323. The upper end of the elastic body 325 is connected to the fixing member 322, and the lower end of the elastic body 325 is connected to the floating member 324. A clamping member 310 is connected to the lower end of the floating member 324.
[0033] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the elastic body 325 is a spring, the second connecting member 323 is a bolt, and the elastic body 325 is inserted through it. One end is fixedly connected to the floating member 324, and the other end is movably connected to the fixed member 322, so that the floating member 324 can compress or release the elastic body 325 relative to the fixed member 322 to move in the vertical direction. Therefore, when the second moving component 220 drives the pressing member 310 to press the product under test in the vertical direction, it has a certain buffering capacity and can prevent damage to the product under test.
[0034] It is understandable that, such as Figure 5 and Figure 6 As shown, a stepped groove 3221 with a through center is provided in the fixing member 322. The stepped groove 3221 can accommodate the floating member 324 and the elastic body 325, thereby making the overall mechanism more compact in the vertical direction.
[0035] It is understandable that, such as Figure 5 As shown, the fastener 322 has a stepped structure with a protruding lower end. The larger horizontal cross-section at the upper end facilitates connection with the first connector 321, while the smaller horizontal cross-section at the lower end effectively reduces structural interference and avoids collision with the carrier plate 100.
[0036] In some specific embodiments of this utility model, the carrier plate 100 has a second groove 130, which penetrates a portion of the sidewall of the product placement groove 110. For example... Figure 1 and Figure 4As shown, in this embodiment, the second groove 130 provides the operator with space to apply force, facilitating the placement of the product to be tested from the product placement slot 110. It is understood that multiple second grooves 130 can be provided without affecting the placement of the product to be tested.
[0037] In some specific embodiments of this utility model, multiple product placement slots 110 are provided. For example... Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, four product placement slots 110 are provided and arranged side by side to simultaneously hold and position multiple products to be tested. It can be understood that when there are multiple product placement slots 110, the inspection module 400 can be positioned across all product placement slots 110 to simultaneously inspect all products to be tested.
[0038] In some specific embodiments of this utility model, multiple clamping members 310 are provided, and the multiple clamping members 310 are spaced apart at the lower end of the first connecting member 321. The clamping members 310 are adapted to the product placement groove 110. For example Figure 1 As shown, in this embodiment, the number of clamping parts 310 is the same as the number of product placement slots 110, which facilitates replacement when a single clamping part 310 is damaged, reducing the maintenance cost of the mechanism.
[0039] In some specific embodiments of this utility model, the first moving component 210 includes a first cylinder lead screw slider 211 and a second cylinder lead screw slider 212 arranged side by side. The first cylinder lead screw slider 211 and the second cylinder lead screw slider 212 have the same structure, and a second moving component 220 is provided on the first cylinder lead screw slider 211 and the second cylinder lead screw slider 212.
[0040] like Figure 5 As shown, in this embodiment, the first cylinder screw slider 211 and the second cylinder screw slider 212 can drive the second moving component 220 and the pressing module 300 to move back and forth precisely and stably, so that the pressing component 310 in the pressing module 300 can reach above the part of the product to be tested that needs to be pressed.
[0041] It is understandable that the first moving component 210 may also adopt common linear drive components such as motor guide rail slider or motor lead screw slider.
[0042] In some specific embodiments of this utility model, the second moving component 220 includes a first cylinder drive component 221 and a second cylinder drive component 222. The first cylinder drive component 221 and the second cylinder drive component 222 have the same structure. The first cylinder drive component 221 is disposed on the first cylinder lead screw slider 211, and the second cylinder drive component 222 is disposed on the second cylinder lead screw slider 212. The pressing module 300 is connected to the transmission ends of the first cylinder drive component 221 and the second cylinder drive component 222.
[0043] like Figure 5 As shown, in this embodiment, the first cylinder drive component 221 and the second cylinder drive component 222 can drive the pressing module 300 to move up and down precisely and stably, so that the pressing component 310 in the pressing module 300 can press down and release the product to be tested.
[0044] It is understandable that the second moving component 220 can also be a common linear drive component such as a motor guide rail slider or a motor lead screw slider.
[0045] In some specific embodiments of this utility model, a base plate 500, a carrier plate 100, and a first moving assembly 210 are also disposed on the base plate 500. For example... Figure 1 and Figure 3 As shown, in this embodiment, the base plate 500 facilitates the formation of an integrated structure for the mechanism, making it convenient for assembly and transportation.
[0046] This utility model embodiment also discloses a testing device, including the above-mentioned electronic pen clamping and positioning mechanism.
[0047] When the device is in use, the clamping module 300 is located above and behind the product placement slot 110, which facilitates the placement of the product to be tested into the product placement slot 110. After the product to be tested is placed into the product placement slot 110, it is attracted by the magnetic attraction element 120 in the first groove 111 and can be placed relatively stably in the product placement slot 110. At this time, the first moving component 210 of the drive module 200 can drive the second moving component 220 and the clamping module 300 to move in the back and forth direction. When the second moving component 220 drives the clamping module 300 to move downward, the clamping component 310 of the clamping module 300 can contact the product to be tested and cooperate with the product placement slot 110 to ensure the flatness of the product to be tested in the product placement slot 110, so that its axial or radial direction is accurately aligned with the processing reference surface, thereby improving the quality and reliability of subsequent processes.
[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
