Description

Technical Field

[0001] This application relates to the field of cosmetic pen detection, and particularly to a cosmetic pen detection device. Background Art

[0002] As a common cosmetic tool, an eyeliner pen usually consists of a pen barrel and a pen cap. The pulling force between the two directly affects the usability and safety of the product. Currently, in the assembly process of the pen cap and the pen barrel, it is necessary to ensure an appropriate tightness when they are combined: if the pulling force is too strong, it is difficult for users to quickly separate the pen cap from the pen barrel during use, resulting in inconvenient operation or even damage to the product structure; if the pulling force is too weak, the pen cap is likely to accidentally fall off in the non-use state, causing the pen tip to be exposed and contact external objects, resulting in pen tip contamination or contamination of other items, affecting the hygiene of the product and the user experience. However, in the existing production process, there are still technical difficulties in the quality control of the pulling force. Due to differences in the specifications, materials, and production processes of eyeliner pens, traditional detection methods are difficult to accurately adapt to the pulling characteristics of different products, and deviation in detection results is likely to occur. For example, there are subjective judgment errors in the manual testing method, and conventional mechanical detection equipment often cannot flexibly adjust the test parameters to adapt to the mechanical characteristics of different models of products, resulting in an imbalance between detection efficiency and accuracy. In addition, if the pulling force is not effectively verified in the production process, some products will enter the market due to unqualified tightness, increasing user complaints and after-sales risks and damaging the brand reputation.

[0038] The embodiments of the present application will be described in detail below.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and should not be construed as a limitation of the present application.

[0039] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present application.

[0040] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0041] In this application, unless otherwise clearly defined and limited, terms such as "installed", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] In this application, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0043] This application mainly detects the eyeliner in the makeup pen, mainly detecting the pulling force of the pen cap of the eyeliner (hereinafter referred to as the product), as well as the line shape drawn, whether it forks, and whether there is ink leakage, etc. The pulling force mentioned above refers to the force required for the pen cap to separate from the pen barrel. The line shape drawn refers to the outline of the line drawn by the eyeliner on the paper. By drawing a line on the paper to simulate the human use state, it is detected whether the drawn line meets the requirements. The forking mentioned above refers to whether the tip of the pen appears to split. The ink leakage mentioned above means that if the ink channel in the eyeliner is blocked, the ink cannot reach the tip position. Since the tip is not wetted by the ink, the original color appears, that is, the tip will appear white. If the tip appears white, it indicates that the product is unqualified, otherwise it is a qualified product.

[0044] Specifically, this application provides a makeup pen detection device. The detection device includes a turntable 100, a feeding component 200, a pulling force detection component 300, and a discharging component 400.

[0045] In one embodiment, the turntable 100 is rotatably mounted on the machine table. Multiple stations for carrying products are provided on the turntable 100. A cap clamping assembly 110 is provided on the turntable 100 at each station. The cap clamping assembly 110 rotates synchronously with the turntable 100. The feeding assembly 200 is mounted on the machine table and is located on one circumferential side of the turntable 100. The feeding assembly 200 feeds products onto the turntable 100. The pulling force detection assembly 300 is fixedly provided on one circumferential side of the turntable 100. The pulling force detection assembly 300 includes a first linear driving member 310 fixedly mounted on the machine table. A cap pulling clamping member 320 is mounted on the moving end of the first linear driving member 310. A tension sensor 330 is mounted on the machine table. A pen rod clamping member 340 is mounted on the tension sensor 330. The discharging assembly 400 is provided on one circumferential side of the turntable 100 and is used for discharging products.

[0046] Refer to Figure 1 and Figure 2 As shown, the turntable 100 is rotatably mounted on the machine table. Further, a driving device adapted thereto is mounted at the bottom of the machine table. The driving device can be composed of components such as a driving motor, a reducer, and a rotary indexer. It can be understood that the reducer can convert the high speed and low torque from the driving motor into a low speed and high torque state, and further cooperate with the rotary indexer to accurately drive different stations on the turntable 100 to rotate to a predetermined position. In order to further improve the rotation accuracy, the driving motor can be selected as a servo motor.

[0047] Refer to Figure 1 、 Figure 2 and Figure 3 As shown, when it is necessary to detect the pulling force of the pen cap of the cosmetic pen, first, the feeding assembly 200 transports the product to the station of the turntable 100. As the turntable 100 rotates, the feeding assembly 200 sequentially transports the products to each station of the turntable 100. Next, as the turntable 100 rotates, the product is moved to the position of the pulling force detection assembly 300. The pulling force detection assembly 300 detects the pulling of the pen cap, preventing the required pulling force from being too large, which may cause inconvenience for the user to remove the pen cap, and also preventing the pen cap from falling off automatically due to too small required pulling force, which may contaminate the items it contacts.

[0048] Further, when it is necessary to detect the pulling force of the pen cap, first, the pen barrel of the product is clamped by the pen barrel clamping member 340. After clamping, the cap-pulling clamping member 320 is transferred to the position of the pen cap by the first linear driving member 310 and clamped thereto. Next, the first linear driving member 310 moves the pen cap clamped by the cap-pulling clamping member 320 upward until the pen cap is separated from the pen barrel. During the process of the pen cap being separated from the pen barrel, the tensile force sensor 330 will detect the force required for the pen cap to be separated from the pen barrel, so as to determine whether the product meets the required pulling force in actual use. It can be understood that the device further includes a compatible processor, a memory, etc. The force detected by the tensile force sensor 330 is compared with the standard pulling force range value pre-stored in the processor and the memory, so as to determine whether the pulling force of the product is qualified.

[0049] In one embodiment, when the first linear driving member 310 and the cap-pulling clamping member 320 cooperate to separate the pen cap from the pen barrel and detect the pulling force, the pen cap clamped by the cap-pulling clamping member 320 is clamped by the cap clamping assembly 110. At this time, the cap-pulling clamping member 320 releases the state of clamping the pen cap. Next, the pen barrel clamping member 340 also releases the state of clamping the pen barrel and returns to the initial state, waiting to detect the pulling force of the next product.

[0050] Further, after the pulling force detection is completed, other parameters of the product can be detected as needed. There is a description of the detection of other parameters of the product in the following text, which will not be elaborated in detail here. After the product detection is completed, the detected product can be unloaded through the unloading assembly 400. It can be understood that multiple unloading assemblies 400 can be installed on the turntable 100, so as to classify and unload products with different unqualified parameters, that is, classify and unload unqualified products and qualified products, so as to facilitate subsequent repair or re-production of the products.

[0051] From the above description, it can be seen that the solution proposed in this application can automatically detect the pulling force of the product, greatly improving the detection efficiency and ensuring the product quality compared with manual detection.

[0052] The loading assembly 200 includes a loading conveyor line 210 arranged on the machine table. A plurality of transfer placement grooves 220 for carrying products are arranged on the loading conveyor line 210. A first two-axis transfer module 230 is arranged on one side of the loading conveyor line 210. A rotating member 240 is installed on the moving end of the first two-axis transfer module 230. A loading clamping member 250 is installed on the rotating end of the rotating member 240.

[0053] Refer to Figure 4As shown, in order to supply products to each station on the turntable 100, first, the feeding conveyor 210 drives the products in each transfer placement groove 220 to move successively to the feeding end of the feeding gripper 250. Then, the feeding gripper 250 grips the product at its feeding end. After gripping, under the drive of the cooperation of the first and second axis transfer module 230 and the rotating part 240, the product gripped by the feeding gripper 250 is transported to the cap assembly 110 station. Specifically, after the feeding gripper 250 grips the product, the first and second axis transfer module 230 first transfers the product to the station, and then the rotating part 240 drives the feeding gripper 250 to rotate, so that the product changes from a horizontal state to a vertical state. Subsequently, the first and second axis transfer module 230 drives the product to be installed on the station again, completing the feeding process.

[0054] In one embodiment, the feeding conveyor 210 has a plurality of convex blocks evenly spaced apart, and transfer placement grooves 220 for accommodating products are provided on the convex blocks. As the feeding conveyor 210 drives the transfer placement grooves 220 on it to rotate, the products at each position are successively transferred to the feeding position of the feeding gripper 250.

[0055] Exemplarily, the first and second axis transfer module 230 is composed of two linear drive cylinders, so as to be able to move in both the horizontal and vertical directions. In this embodiment, the rotating part 240 is a rotating cylinder, and the feeding gripper 250 is formed by assembling a jaw cylinder and two jaws adapted to the product.

[0056] The cap assembly 110 is provided with a first lifting drive 111 on the turntable 100. The moving end of the first lifting drive 111 is provided with a first driven block 112, and a first clamping cylinder 113 is installed on the first driven block 112.

[0057] Refer to Figure 1 、 Figure 2 And Figure 5 As shown, since the cap assembly 110 is installed on the turntable 100, the cap assembly 110 will rotate synchronously with the turntable 100. After the pen cap pulling force is detected, the first lifting drive 111 drives the first clamping cylinder 113 on the first driven block 112 to move to the position of the cap pulling gripper 320, and the first clamping cylinder 113 clamps the pen cap gripped by the cap pulling gripper 320. At the same time, the cap pulling gripper 320 releases the clamping state of the pen cap. It can be understood that at this time, the pen cap clamped by the first clamping cylinder 113 will rotate synchronously with the turntable 100.

[0058] In this embodiment, a plurality of blanking components 400 are provided at the blanking position. The blanking components 400 are used to blank out unqualified products of different descriptions and qualified products, thereby facilitating subsequent processes such as classification and repair. Specifically, the blanking component 400 includes a second two-axis transfer module 410 fixedly installed on the machine table. A second driven block 420 is installed at the moving end of the second two-axis transfer module 410. A blanking clamping member 430 is installed at the moving end of the second driven block 420. A blanking conveyor line 440 for blanking products is provided on one side of the second two-axis transfer module 410.

[0059] Refer to Figure 1 、 Figure 2 and Figure 7 As shown, first, the second two-axis transfer module 410 drives the blanking clamping member 430 to move to the blanking station. Then, the blanking clamping member 430 clamps the product. After clamping, the second two-axis transfer module 410 moves the product to the position of the blanking conveyor line 440 again. Next, the blanking conveyor line 440 releases the clamping state of the product, and then the product drops onto the blanking conveyor line 440 to achieve blanking.

[0060] Exemplarily, the structure of the second two-axis transfer module 410 is the same as that of the above-mentioned first two-axis transfer module 230, both of which are formed by assembling two linear drive cylinders, so as to be able to move in both horizontal and vertical directions.

[0061] A cap pressing component 500 is provided between the feeding component 200 and the drawing force detection component 300. The cap pressing component 500 includes a second lifting drive member 510 provided on the machine table. A third driven block 520 is provided at the moving end of the second lifting drive member 510. A pressing block 530 is installed on the third driven block 520.

[0062] Refer to Figure 1 、 Figure 2 and Figure 6 As shown, before the drawing force test is avoided, in order to accurately measure the drawing force of the pen cap, the pen cap needs to be fully installed on the pen barrel. For this reason, a cap pressing component 500 is provided between the drawing force detection component 300 and the feeding component 200 to press the pen cap, so that the pen cap is fully installed on the pen barrel, preventing the drawing force detection from failing due to the incomplete combination of the pen cap and the pen barrel of individual products. Specifically, when pressing is required, first, the second lifting drive member 510 drives the third driven block 520 to move downward, thereby driving the pressing block 530 to move downward. As the pressing block 530 moves, it will contact the pen cap. As the pressing block 530 continues to be driven downward by the second lifting drive member 510, the pen cap is pressed, so that the pen cap can be fully combined with the pen barrel before the drawing force of the pen cap is detected, thereby improving the accuracy of detecting the drawing force.

[0063] A linear detection component 600 is arranged between the drawing detection component 300 and the blanking component 400. The linear detection component 600 includes a mounting plate 610 fixedly installed on the machine table. On one side of the mounting plate 610, a unwinding reel 621 for unwinding the paper and a winding reel 622 for winding the paper are respectively rotatably arranged. At the end of the mounting plate 610 facing the turntable 100, a second linear driving member 630 is installed. A slider 640 slidably arranged on the mounting plate 610 is installed at the moving end of the second linear driving member 630. A roller 650 is installed on the slider 640. The paper from the unwinding reel 621 passes through the roller 650 and is wound by the winding reel 622. A first vision detection member 660 is also fixedly installed on the mounting plate 610. The first vision detection member 660 is located on the path of the paper from the roller 650 to the winding reel 622. A rotation driving component 120 for driving the product to rotate is installed on the machine table at the position of the roller 650.

[0064] Refer to Figure 8 and Figure 9 As shown, in order to be able to detect whether the lines drawn during the actual use of the product can meet the requirements, in this application, the actual use situation is simulated by drawing lines on the paper. Specifically, the paper is unwound by the unwinding reel 621, and then the paper passes through the roller 650 and is wound by the winding reel 622. Further, when the product is rotated and moved to the position of the roller 650 by the turntable 100, the second linear driving member 630 drives the slider 640 and the roller 650 to move towards the turntable 100 direction. As it gradually approaches the lower roller 650, the roller 650 drives the paper to gradually contact the pen tip of the product. After the pen tip contacts the paper, the paper is wound. As the paper is wound and rotated, the pen tip will draw corresponding lines on the paper. These lines are visually detected by taking pictures with the first vision detection member 660. By comparing the lines on the paper with the pre-stored standard lines in the memory, it is determined whether the pen tip of the product is qualified; furthermore, in order to be able to detect all directions of the pen tip, the rotation driving component 120 drives the product at the station to rotate, so that lines can be drawn by different parts of the pen tip in different directions, thereby performing a full-range detection; after the detection is completed, the second linear driving member 630 drives the slider 640 and the roller 650 to return to the initial state and wait for the next product to be detected. Similarly, the winding reel 622 also stops winding and waits for the next product to be detected.

[0065] Exemplarily, the first vision detection member 660 can be composed of components such as an industrial camera and a coaxial light source. And, in order to enable the winding reel 622 to rotate and wind, a motor is installed on the mounting plate 610, and the winding reel 622 is driven to rotate by the motor to achieve winding.

[0066] A plurality of guide wheels 670 are rotatably installed on the mounting plate 610. The guide wheels 670 are used to guide the paper from the unwinding reel 621.

[0067] Please continue to refer to Figure 8 and Figure 9 As shown, since there is a certain distance between the unwinding reel 621 and the roller 650, and between the roller 650 and the winding reel 622, in order to enable the paper to move along a preset trajectory, a plurality of guide wheels 670 are installed on the mounting plate 610 to guide the paper so that it can move along the preset trajectory.

[0068] Furthermore, in order to prevent the paper from wrinkling during the movement, it is necessary to tension the paper. Specifically, a tensioning structure 690 is installed on the mounting plate 610, and the tensioning structure 690 is located on the path between the unwinding reel 621 and the roller 650. The tensioning structure 690 includes a swing arm 691 rotatably installed on the mounting plate 610. A tensioning wheel 692 is rotatably installed at the end of the swing arm 691 away from the mounting plate 610. The outer peripheral surface of the tensioning wheel 692 contacts the surface of the paper. Under the action of gravity, the tensioning wheel 692 will rotate downward with respect to the swing arm 691, thereby applying pressure to the paper, and further realizing the tensioning of the paper.

[0069] Please continue to refer to Figure 8 and Figure 9 As shown, in order to enable the paper to be smoothly wound by the winding reel 622, a winding drive assembly 680 is provided on the path between the roller 650 and the winding reel 622. The paper is conveyed to the winding reel 622 through the winding drive assembly 680, thereby reducing the force required for the winding reel 622 to wind, and enabling the winding reel 622 to quickly achieve winding. Specifically, the winding drive assembly 680 includes a first motor 681 fixedly installed on the mounting plate 610. A driving wheel 682 is installed on the rotating shaft of the first motor 681, and a driven wheel 683 is rotatably installed on the mounting plate 610 at the position of the driving wheel 682. The paper passes through the path formed by the driving wheel 682 and the driven wheel 683, and the driving wheel 682 and the driven wheel 683 are respectively in contact with two surfaces of the paper. As the first motor 681 drives the driving wheel 682 to rotate, the paper is driven to move towards the winding reel 622, thereby improving the winding efficiency of the winding reel 622.

[0070] At least one second vision detection component 700 is installed on the machine table on the circumferential side of the turntable 100, and a rotation drive assembly 120 for driving the product to rotate is provided at the position of the second vision detection component 700.

[0071] Refer to Figure 1 , Figure 2 and Figure 10As shown in the figure, in order to be able to detect whether the tip of the product is split and whether there is exposed white, at least one second vision detection component 700 is installed on the machine table. The tip of the pen is photographed by the second vision detection component 700 to achieve vision detection. The photographed photo is compared with the parameters such as the shape and color of the standard pen tip in the memory, so as to judge whether the tip of the pen is split and whether there is exposed white. If there is splitting and exposed white, it means that the tip of the product is unqualified, otherwise it is a qualified product.

[0072] In order to further detect the positions of each direction of the pen tip, the pen barrel is driven to rotate by the rotation driving component 120, so as to realize the rotation of the pen tip, and thus each part of the pen tip can be detected and identified.

[0073] In this embodiment, there are two second vision detection components 700 in total. One second vision detection component 700 detects whether the tip of the product is split, and the other second vision detection component 700 detects whether the tip has exposed white, and the detection is carried out separately.

[0074] Exemplarily, the second vision detection component 700 can be composed of components such as an industrial camera and a coaxial light source. The photographed photo is compared with the photos of qualified products pre-stored in the memory to judge whether the product is qualified.

[0075] A carrying component 101 is arranged at each station on the turntable 100. The carrying component 101 includes an installation hole 1011 penetrating through each station on the turntable 100. A bearing 1012 is installed in the installation hole 1011. A first installation sleeve 1013 is installed in the inner ring of the bearing 1012. A first accommodation hole 10131 penetrates through the center of the first installation sleeve 1013. A second installation sleeve 1014 is arranged in the first accommodation hole 10131. A second accommodation hole 10141 penetrates through the center of the second installation sleeve 1014. The second accommodation hole 10141 is used to place the product. A support ring 102 is installed on the machine table. The support ring 102 is located at each station and is used to support the product at each station.

[0076] Refer to Figure 11 and Figure 12As shown, when the product is loaded, the product can be placed in the second receiving hole 10141 in a vertical state. Since the second mounting sleeve 1014 is placed and fixed in the first receiving hole 10131 of the first mounting sleeve 1013, and the first mounting sleeve 1013 is placed in the inner ring of the bearing 1012, when the product needs to be rotated, it is only necessary to drive the first mounting sleeve 1013 to rotate, and the height of the second mounting sleeve 1014 is less than the height of the first mounting sleeve 1013, that is, the bottom of the second mounting sleeve 1014 does not exceed the first mounting sleeve 1013. 013. Furthermore, in order to prevent the product in the second accommodating hole 10141 from falling off, an annular support ring 102 is installed on the machine to support the product through the support ring 102 to prevent it from falling off the second accommodating hole 10141. In order to be able to drive the product to rotate by rotating the first mounting sleeve 1013, there may be a certain friction between the product and the inner wall of the second accommodating hole 10141, so that the second mounting sleeve 1014 can be driven to rotate by the first mounting sleeve 1013 and then the product in the second accommodating hole 10141 can be driven to rotate.

[0077] Furthermore, if the pen body of the product is of irregular shape or other shapes, the inner wall shape of the second accommodating hole 10141 should be adapted to the shape of the pen body of the product. If the pen body is a cylinder, a certain amount of rubber can be fitted inside the second accommodating hole 10141 to increase the friction between the inner wall of the second accommodating hole 10141 and the pen body of the product, so that the second mounting sleeve 1014 can be driven to rotate through the first mounting sleeve 1013 to drive the product to rotate.

[0078] In order to achieve a fixed connection between the second mounting sleeve 1014 and the first mounting sleeve 1013 bracket, an internal thread can be set inside the first accommodating hole 10131, and an external thread can be set on the outer surface of the second mounting sleeve 1014, so as to achieve fixation by threaded connection, thereby enabling force transmission.

[0079] It is understandable that the provision of the bearing 1012 in the mounting hole 1011 enables the first mounting sleeve 1013 to rotate under force, thereby reducing the friction between the first mounting sleeve 1013 and the inner wall of the mounting hole 1011 .

[0080] See also Figure 11 and Figure 13As shown in the figure, in order to fixedly connect the support ring 102 to the machine table, a plurality of support components 103 are provided at the bottom of the support ring 102 to fix the support ring 102 in place. Specifically, the support component 103 includes a support column 1031 provided on the machine table. An avoidance groove 10311 is formed in the circumferential surface of the support component 103 along the vertical direction, and the avoidance groove 10311 extends to the central position of the support column 1031. One side of the support column 1031 abuts against the support ring 102, and one end of the support column 1031 away from the support ring 102 abuts against the machine table. A fixing rod 1032 is arranged in the avoidance groove 10311. The fixing rod 1032 passes through the tabletop of the machine table and the boss on the circumferential surface of the support ring 102. Finally, nuts 1033 at both ends of the fixing rod 1032 are used to fasten the boss on the circumferential surface of the support ring 102 and fasten the fixing rod 1032 to the machine table.

[0081] It can be understood that by forming an avoidance groove 10311 in the circumferential surface of the support column 1031 along the vertical direction, that is, the fixing rod 1032 only needs to be arranged in the avoidance groove 10311 from the side, so as to facilitate the connection between the two, and there is no need to pass through the avoidance groove 10311 in the vertical direction, greatly improving the installation efficiency.

[0082] The rotation drive assembly 120 includes a second motor 121 fixedly installed on the machine table. A transmission shaft 122 is installed at the rotating end of the second motor 121, and a transmission wheel 123 is fixedly arranged on the outer circumference of the end of the transmission shaft 122.

[0083] Refer to Figure 8 、 Figure 9 and Figure 10 As shown in the figure, in order to drive the product to rotate, a second motor 121 is installed on the machine table. The second motor 121 drives the transmission wheel 123 at the end of the transmission shaft 122. The transmission wheel 123 contacts the first mounting sleeve 1013, so as to realize the transmission of the rotational force to drive the first mounting sleeve 1013 to rotate, and then drive the product to rotate, so as to meet the multi-directional detection of the product.

[0084] It can be understood that the transmission wheel 123 can be made of rubber. Due to the deformable characteristic of the rubber material, when the turntable 100 drives the first mounting sleeve 1013 to rotate to the position of the transmission wheel 123, the transmission wheel 123 deforms to a certain extent and abuts against the first mounting sleeve 1013, and the force is transmitted under the action of friction.

[0085] In this embodiment, when the product is between the blanking component 400 and the second vision detection component 700, that is, after the product is detected by the second vision detection component 700, the clamping cap component 110 drives the first clamping cylinder 113 to move to place or install the pen cap clamped by the first clamping cylinder 113 on the pen barrel, so that the pen cap returns to the pen barrel again. Moreover, a cap pressing component 500 is also provided between the blanking component 400 and the second vision detection component 700. The cap pressing component 500 presses the pen cap located on the pen barrel again, so that the pen cap and the pen barrel are fitted and installed again. It should be noted that the pressing operation can only be performed by the cap pressing component 500 when there is a pen cap on the pen barrel.

[0086] In this embodiment, the cap pulling and clamping member 320, the pen barrel clamping member 340, the feeding clamping member 250, the first clamping cylinder 113 and the blanking clamping member 430 described above are all jaw cylinders. Clamping blocks are installed at both clamping ends of the jaw cylinder, and grooves adapted to the shape of the product are formed on the clamping blocks. The two clamping blocks are combined to clamp the product.
