[0002] This application claims priority under Chinese Patent CN2024112950210, filed on September 14, 2024. The disclosures of these prior applications are considered part of the disclosures of this application and are incorporated herein by reference in their entirety. Technical Field

[0003] This invention relates to the field of drawing machine devices, and in particular to a drawing machine. Background Technology

[0004] A drawing machine is a device used to assist in artistic creation. It fixes tools such as pens or knives on the jig of the drawing machine, and controls the tools to move along a preset trajectory through a control module to achieve drawing or carving. Existing small XY type drawing machines include a main unit, a jig structure, an X-axis structure, and a Y-axis structure. The X-axis structure has bases on both sides. The X-axis structure and the Y-axis structure are installed perpendicular to each other with the main unit as the reference. The main unit can move along the X-axis structure. The jig structure is assembled onto the Y-axis structure and can move along the Y-axis structure. The jig structure is equipped with a lifting drive motor and a lifting jig. The lifting drive motor is electrically connected to the main unit through wires to realize power supply and communication.

[0005] Existing XY-type drawing machines use a wire protection structure with a certain shape and flexible bending in the upper area between the main unit and the clamping structure. The wire is placed inside the wire protection structure, so that the wire is always above the main unit and the clamping structure when the clamping structure is away from or close to the main unit. However, the wire protection structure occupies the space above the XY-type drawing machine, so a certain height of working space needs to be reserved when the XY-type drawing machine is in operation. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing drawing machines, which require a wire protection structure to keep the wire always above the main unit and clamping structure, resulting in the need to reserve a certain height of working space for the drawing machine. The invention provides a drawing machine in which the wire between the working parts and the circuit module is designed to be retractable.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A drawing machine includes: a first guide rail bracket, a main unit, a circuit module, and a working component; the first guide rail bracket has a first guide rail and support seats constructed at both ends of the first guide rail; the main unit is slidably mounted to the first guide rail and includes: a first driver, a first transmission member mounted along the first guide rail and coupled to the first driver, a second guide rail perpendicular to the first guide rail, a second driver, and a second transmission member along the second guide rail and coupled to the second driver; the circuit module is disposed in the main unit; the working component is slidably coupled to the second guide rail and has a vertically movable working clamp and a working drive mechanism for driving the vertical movement of the working clamp, and the working component and the circuit module are electrically connected by wire; the wire is configured such that when the working component moves along the second guide rail, at least a portion remains in close contact with the surface of the second guide rail; or, the wire is configured such that when the working component moves along the second guide rail, it is in a taut state and close to or near the outer side of the surface of the second guide rail.

[0009] Compared with the prior art, the drawing machine of this utility model uses wires to electrically connect the working part and the circuit module. The wires are arranged such that when the working part moves along the second guide rail, at least a portion of the wires remain in close contact with the surface of the second guide rail, or are in a taut state and close to or near the outer side of the surface of the second guide rail. This reduces the space occupied by the wires when the drawing machine is in use. The wires between the working part and the circuit module can be retracted and extended. When the working part is close to the main unit, the wires will not affect the operation, thus eliminating the need for an additional wire protection structure.

[0010] As a way of setting up cables:

[0011] The self-retracting cable is a flexible spiral cable.

[0012] The main unit has a wire storage channel with an opening along the direction of the second guide rail; the working part and the circuit module are electrically connected by a self-retracting wire, and one end of the self-retracting wire is located inside the wire storage channel. When the working part moves along the direction of the main unit, the self-retracting wire can be stored in the wire storage channel.

[0013] The working component and the circuit module are electrically connected by a self-retracting cable, and one end of the self-retracting cable is located in the cable storage channel. When the working component moves along the direction of the main component, the self-retracting cable can be stored in the cable storage channel, so that the cable between the working component and the circuit module can be retracted and extended through the cable storage channel.

[0014] The cable storage channel is constructed on the side of the second guide rail, and the size of the cable storage channel is configured to be larger than the diameter of the cable in its stored state.

[0015] As another way to set up the cable:

[0016] The upper side of the second guide rail has a wire storage groove extending along the length direction; the working component and the circuit module are electrically connected by a sheathed wire. The sheathed wire is fixed to the wire storage groove constructed on the second guide rail at a predetermined length from the inner end of the second guide rail. The end of the sheathed wire connected to the working component is located on the side close to the outer end of the second guide rail. When the working component moves relative to the main component, the free part of the sheathed wire can be stored or pulled out along the wire storage groove.

[0017] By using sheathed wires and utilizing wire storage slots to store and release some wire segments, the sheathed wires can be self-stored and flipped up during the movement of the working parts, resulting in a simple structure and high reliability.

[0018] The sheathed wire is fixed to the wire storage groove by a wire pressing block. The wire storage groove is a V-shaped groove or an inverted trapezoidal groove that is constructed on the upper part of the second guide rail and connected to the upper side. The wire pressing block is constructed in a V-shape or inverted trapezoidal shape that matches the shape of the wire storage groove. The wire pressing block is inserted into the wire storage groove from the end of the second guide rail.

[0019] Furthermore, the main unit also includes a housing, with the circuit module disposed within the housing such that the circuit module is not disposed on the support base or directly on the outer surface of the main unit; or, the main unit also includes a housing, with the circuit module disposed within the housing such that the circuit module is not disposed on the support base or directly on the outer surface of the main unit, the circuit module including a control device configured to be operable from outside the housing.

[0020] Furthermore, the circuit module includes a main control circuit and a control circuit, with the main control circuit installed in the lower part of the housing and the control circuit installed in the upper part of the housing.

[0021] Furthermore, the housing includes a first housing and a second housing, which respectively cover the lower and upper parts of the main unit. The main control circuit is installed inside the first housing, and the control circuit is installed inside the second housing.

[0022] Furthermore, the main unit also includes a first substrate, a second substrate, and a main unit pulley; the first substrate is arranged on the upper side of the first guide rail and is slidably connected to the first guide rail by the main unit pulley, and the first driver is installed below the first substrate; the second substrate is connected to the upper side of the first substrate, and the second guide rail and the second driver are installed on the upper side of the second substrate; the first housing covers at least a portion of the lower part of the first substrate, and the second housing covers at least a portion of the upper part of the second substrate.

[0060] The embodiments of this utility model are described below with reference to the accompanying drawings:

[0061] See Figures 1 to 28 One embodiment of the drawing machine of this application includes: a first guide rail bracket 1, a main unit 2, a working unit 3, and one or more quick locking mechanisms 4.

[0062] The first guide rail bracket 1 has a first guide rail 1.1 and support seats 1.2 constructed at both ends of the first guide rail 1.1. The first guide rail 1.1 has first slide rails 1.11 constructed on opposite sides of the first guide rail 1.1.

[0063] The host component 2 includes: a first part 2a, a second part 2c, and a circuit module.

[0064] The first part 2a has a first substrate 2a.1, a main pulley 2a.2, a first driver 2a.3, a first transmission member 2a.4, and a first housing 2.1. The main pulley 2a.2 is mounted on the underside of the first substrate 2a.1 and configured to couple with the first slide rail 1.11; the first driver 2a.3 is mounted on the underside of the first substrate 2a.1; the first transmission member 2a.4 is mounted along the first guide rail 1.1 and coupled with the first driver 2a.3; the first part 2a is assembled to the first guide rail 1.1 via the main pulley 2a.2; the first housing 2.1 covers at least a portion of the upper parts of the first substrate 2a.1.

[0065] The second part 2c includes a second substrate 2c.1, a second guide rail 2c.2, a second driver 2c.3, a second transmission member 2c.4, and a second housing 2.2. The second guide rail 2c.2 is mounted on the upper side of the second substrate 2c.1 and configured to be perpendicular to the first guide rail 1.1. Second slide rails 2c.21 are constructed on opposite sides of the second guide rail 2c.2. The second driver 2c.3 is mounted on the upper side of the second substrate 2c.1. The second transmission member 2c.4 is arranged along the second guide rail 2c.2 and coupled to the second driver 2c.3. The second housing 2.2 covers at least a portion of the lower part of the second substrate 2c.1. The circuit module e is arranged within at least one of the first housing 2.1 and the second housing 2.2, such that the circuit module e is not arranged on the support base 1.2 or not directly arranged on the outer surface of the main unit 2.

[0066] The working component 3 includes: a working support 3.1, a working fixture 3.3, and a working drive mechanism 3.4. The working support 3.1 is coupled to the second guide rail 2c.2 via a working pulley 3.2; the working fixture 3.3 is vertically movable relative to the support 3.1; the working drive mechanism 3.4 is used to drive the working fixture 3.3 to move vertically; one or more quick locking mechanisms 4 are used to lock the second base plate 2c1 and the first base plate 2a1 after the second part 2c is installed on the upper side of the first part 2a.

[0067] In one embodiment illustrated in the accompanying drawings, a single quick-locking mechanism 4 is provided. In other embodiments, a greater number of quick-locking mechanisms 4 may be provided, such as two or three; however, a larger number will increase the time required for installation and removal.

[0068] One embodiment of the first transmission member 2a.4 is a synchronous belt. For example, both ends of the first transmission member 2a.4 are fixed to the first guide rail 1.1. The first driver 2a.3 includes a motor and a first drive wheel 2a.31 connected to the motor. The first drive wheel 2a.31 is coupled to the first transmission member 2a.4. When the first driver 2a.3 drives the first drive wheel to rotate, since both ends of the first transmission member 2a.4 are fixed to the first guide rail 1.1, the first driver 2a.3 moves along the first transmission member 2a.4, thereby driving the main unit 2 to move along the first guide rail 1.1. The first transmission member 2a.4 can also be other transmission structures known in the art.

[0069] One embodiment of the second transmission member 2c.4 is a synchronous belt, specifically a recirculating belt. The second transmission member 2c.4 is coupled along the second guide rail 2c.2, bypassing a transmission wheel 2c.41 mounted on its outer end, and coupled to a second drive wheel 2c.31 of the second driver 2c.3. The working bracket 3.1 is directly or indirectly fixed to the second transmission member 2c.4. When the second driver 2c.3 operates, it drives the second transmission member 2c.4 to move the working component 3 along the second guide rail 2c.2. The second transmission member 2c.4 can also be other transmission structures known in the art.

[0070] See Figure 15 In one embodiment, the second guide rail 2c.2 is fixed to the second substrate 2c.1 by screws.

[0071] Because the drawing mechanism is constructed in two main parts, the main unit 2 has a detachable upper and lower structure. The main unit 2 includes a first housing 2.1 and a second housing 2.2. The circuit module e is arranged inside the main unit 2. The first part 2a and the second part 2c of the main unit 2 are installed and disassembled using a hand-held quick-locking mechanism 4, which is convenient and quick, while reducing packaging and transportation volume and cost. In this application, the circuit module e is arranged inside the first housing 2.1 and / or the second housing 2.2, which covers and protects it, simplifies the structure of the support base 1.2, and, together with the quick-locking mechanism 4, enables quick installation and disassembly.

[0072] See Figures 2 to 6 In some embodiments, positioning structures 2a.10 and 2c.10 are constructed between the first substrate 2a.1 and the second substrate 2c.1. Specifically, Figures 2 to 6 In the illustrated embodiment, positioning structure 2a.10 is a hole and positioning structure 2c.10 is a pin. When the first part 2a is installed onto the second part 2c, the pin 2c.10 is inserted into the corresponding hole 2a.1.

[0073] See Figures 2 to 21 In some embodiments, the first substrate 2a.1 and the second substrate 2c.1 are metallic structures, which can provide excellent structural strength and stability. Materials such as steel and aluminum alloys can also be used, or other known materials.

[0074] See Figures 2 to 16 In some embodiments, the quick-locking mechanism 4 includes: a locking rod 4.1 rotatably and axially restrictedly mounted on a second substrate 2c.1, the lower part of the locking rod 4.1 having a locking rod threaded portion 4.11, and the upper part of the locking rod 4.1 passing through the surface of the second housing 2.2; a handheld control portion 4.3 disposed on the upper part of the locking rod 4.1; and a threaded hole 4.2 constructed on the first substrate 2a.1 that mates with the locking rod threaded portion 4.11. The quick-locking mechanism 4, employing the above-described scheme, allows for direct handheld operation, offering convenience, simplicity, and speed. (See attached...) Figures 2 to 16 In the illustrated embodiment, the handheld control unit 4.3 is a knob, which may be equipped with an anti-slip structure, such as the protrusion shown in the attached figure, or an anti-slip textured structure.

[0075] See Figures 2 to 16The second substrate 2c.1 has a corresponding first control mounting hole 4.12, and the second housing 2.2 has a corresponding second control mounting hole 2.240. The locking rod 4.1 is mounted in the first control mounting hole 4.12 and the second control mounting hole 2.240, and the locking rod threaded portion 4.11 of the locking rod 4.1 protrudes from the lower side of the first control mounting hole 4.12. The handheld control portion 4.3 restricts the outer end of the locking rod 4.1 from disengaging from the second control mounting hole 2.240. When the first part 2a is locked to the second part 2c by the handheld control portion 4.3, the user rotates the handheld control portion 4.3, and the locking rod threaded portion 4.11 is screwed into the threaded hole 4.2.

[0076] In one embodiment, when the threaded portion 4.11 of the locking rod is screwed into the threaded hole 4.2, the hand-held control portion 4.3 abuts against the second part 2, such as the second housing 2.2, thereby ensuring a secure connection between the first part 2a and the second part 2c.

[0077] like Figure 4 , Figure 4 and Figure 16 As shown, the lower side of the handheld control part 4.3 has a first locking surface, and the upper side of the second control mounting hole 2.240 has a second locking surface. When the threaded part 4.11 of the locking rod is screwed into the threaded hole 4.2, the first locking surface presses against the second locking surface. Since the first locking surface and the second locking surface are planar, it can ensure that the first part 2a and the second part 2c are securely locked.

[0078] Specifically, the handheld control unit 4.3 has a first boss 4.31 on its lower side, and a first locking surface on its lower surface. The second control mounting hole 2.240 has a second boss on its upper side, and a second locking surface on its lower surface.

[0079] See Figures 3 to 16 A retaining ring 4.13 is installed below the first control mounting hole 4.12 on the locking rod 4.1. Specifically, the retaining ring 4.13 can be installed in the groove of the locking rod 4.1. The retaining ring 4.13 can prevent the locking rod 4.1 from disengaging from the second base plate 2c.1.

[0080] See Figure 3 and Figure 4 , Figure 15 and Figure 16 In one embodiment, the positioning structures 2a.10 and 2c.10 are pin hole structures. The height of the portion of the locking rod 4.1 located at the lower end of the snap ring 4.13 is less than the height of the pin 2c.10, so as to avoid interfering with the docking of the pin 2c.10 and the pin hole 2a.10. That is, when the first part 2a and the second part 2c are engaged, the lower end of the locking rod 4.1 does not interfere with the docking of the locking rod 4.1 and the pin hole 2a.10.

[0081] See Figures 29 to 33In another embodiment shown, the quick locking mechanism 4 includes a locking rod 4.1, the lower part of which has a locking rod threaded portion 4.11, and the locking rod 4.1 passes through the upper part of the second part 2c through the first control mounting hole 4.12 constructed on the first substrate 2a.1 and connects to the threaded hole 4.2 constructed on the first substrate 2a.1.

[0082] The second housing 2.2 has a corresponding second control mounting hole 2.240. The locking rod 4.1 also includes a locking rod head 4.3' disposed at the upper end. The locking rod head 4.3' is configured with a structure for coupling a locking / unlocking tool. When the locking rod 4.1 is connected and locked to the threaded hole 4.2 of the first base plate 2a.1, the locking rod head 4.3' acts on the second housing 2.2 to lock the first part 2a and the second part 2c. Figures 29 to 33 In the illustrated embodiment, the locking bar head 4.3' is equipped with an internal hexagonal structure, which can withstand greater torque. Of course, other existing structures, such as triangular or star-shaped structures, can also be used.

[0083] In one embodiment, the second control mounting hole 2.240 is a countersunk hole, and the locking rod head 4.3' acts on the bottom of the countersunk hole. For aesthetic purposes, a cover plate 4.1' can be configured to seal the countersunk hole.

[0084] See Figures 3 to 6 , Figures 10 to 16 The positioning structures 2a.10 and 2c.10 include at least two sets, with at least one set configured on one side of the first guide rail 1.1 and at least the other set configured on the opposite side of the first guide rail 1.1. This configuration ensures that the positioning is stable and reliable.

[0085] like Figures 3 to 6 , Figures 10 to 16 , Figures 29 to 33 In the embodiment shown, positioning structures 2a.10 and 2c.10 are respectively a pin hole disposed on the first substrate 2a.10 and a pin 2c.10 disposed on the first substrate 2a.10.

[0086] See Figures 1 to 28Because the weight of the second part 2c and the working component 3 causes the gravity of the second part 2c on the side closer to the working component 3 on the centerline of the first guide rail 1.1 to be greater than the eccentric gravity on the other side, but because at least one set of positioning structures 2a.10 and 2c.10 is configured on one side of the first guide rail 1.1 and at least another set is configured on the opposite side of the first guide rail 1.1, the eccentric gravity of the second part 2c acts laterally on the positioning structures 2a.10 and 2c.10. Therefore, the quick-locking mechanism 4 can easily and stably lock the first part 2a and the second part 2c. This application optimizes the force distribution of the quick-locking mechanism 4 by cooperating with the quick-locking mechanism 4 and the positioning structures 2a.10 and 2c.10, utilizing the positioning structures 2a.10 and 2c.10 to bear the lateral forces of the first part 2a and the second part 2c. Therefore, at least one quick-locking mechanism 4 is required to meet the connection requirements.

[0087] See Figure 15 In one embodiment, the second guide rail 2c.2 is provided with a locking rod clearance hole 2c.20 to avoid the locking rod 4.1. The second guide rail 2c.2 is connected to the second base plate 2c.1 by a connector such as a screw 2c.2, specifically, screws 2c.2 are connected to both sides of the locking rod clearance hole 2c.20.

[0088] See Figures 3 to 20 In some embodiments, the circuit module e includes a main control circuit e1 and a control circuit e2. The main control circuit e1 is mounted in the second part 2c, and the control circuit e2 is mounted in the first part 2a. The control circuit e2 and the main control circuit e1 are connected by a wired or wireless connection. The control circuit e2 includes a control device e21 configured to be operable from outside the second housing 2.2. In other embodiments, a control device (not shown) operable from outside the first housing 2.1 may also be configured.

[0089] The main control circuit e1 is used to receive data output from the control circuit e2, receive and process data input to the drawing machine, output data to external devices, and control various components of the drawing machine.

[0090] See Figure 7 The first housing 2.1 is connected to the first substrate 2a.1 via a connector such as screw 2a.11', and the second housing 2.2 is connected to the second substrate 2c.1 via a connector such as screw 2c.11'.

[0091] In one embodiment, the control circuit e2 and the main control circuit e1 are connected by a wired plug-in connection, which facilitates connection and disassembly.

[0092] See Figures 1 to 16The first housing 2.1 has a first housing sidewall that covers the lower component of the first substrate 2a.1. The interior of the first housing sidewall is configured to receive the lower component of the first substrate 2a.1. Notches 2.11 that avoid the first guide rail 1.1 are constructed on opposite sides of the first housing sidewall along the length direction of the first guide rail 1.1.

[0093] In one embodiment, the main control circuit e1 is mounted on the first housing 2.1.

[0094] See also Figures 1 to 16 As shown, the depth of the first housing 2.1 corresponding to the position of the first driver 2a.3 is increased to make the overall space utilization of the first housing 2.1 more compact.

[0095] See Figures 1 to 16 The second housing 2.2 is constructed with a second housing sidewall covering the upper component of the second substrate 2c.1. The interior of the second housing sidewall is constructed to receive the upper component of the second substrate 2c.1. A notch 2.21 is constructed on the outer side of the second housing sidewall along the length direction of the second guide rail 2c.2 to avoid the second guide rail 2c.2.

[0096] In one embodiment, the control circuit e2 is mounted on the inner side of the top wall of the second housing 2.2.

[0097] In one embodiment, the control circuit e2 includes a control device e21, which includes a power control e211 and an on control e212 (which integrates a pause function in some embodiments). Of course, the power control e211 and the on control e212 shown in the figures include components such as buttons that are operated from outside the second housing 2.2.

[0098] like Figure 11 and Figure 13 As shown, the rear side of the second housing 2.2 has a heat dissipation hole structure 2.201 of the second part 2c. Of course, a similar heat dissipation hole structure can also be constructed on the first housing 2.1 as needed.

[0099] In some embodiments, the main control circuit e1 is provided with a data interface, which is connected to external data hardware via a data line. The corresponding first housing 2.1 is provided with a data interface clearance hole.

[0100] For the heat dissipation of the first part 2a, it can be directly achieved through the aforementioned data interface clearance hole.

[0101] See Figures 1 to 16The second housing 2.2 has a high portion 2.21' corresponding to the second driver 2c.3, and a low portion 2.22' corresponding to the upper side of the connecting end of the second guide rail 2c.2.

The second housing 2.2 adopts the above structure, the second part 2c has a compact structure, and at the same time echoes the shape of the first part 2a, making the product aesthetically pleasing.

[0102] See also Figures 1 to 16 As shown, the depth of the first housing 2.1 corresponding to the position of the first driver 2a.3 is increased to make the overall space utilization of the first housing 2.1 more compact.

[0104] One solution for self-retracting cable is a helical spring cable. When the working part 3 approaches the main body 2, the helical spring cable retracts itself and can at least partially enter the cable retraction channel 2.20' as the working part 3 approaches the main body 2. Of course, the diameter and dimensions of the cable retraction channel 2.20' must be designed to be larger than the diameter of the helical spring cable.

[0105] In other embodiments, other wires that can be spring-loaded can also be used.

[0106] See Figures 22 to 28 In some embodiments, the working component 3 further includes a connecting member 3.5 that connects to the working fixture 3.3. The connecting member 3.5 is vertically movably connected to the working support 3.1 via one or more guide rods 3.6. The working drive mechanism 3.4 includes a working motor 3.41 mounted on the working support 3.1, a rack member 3.42 slidably mounted on at least one of the guide rods, an elastic element 3.43 acting between the rack member 3.42 and the connecting member 3.5, and one or more gears 3.44 coupling the working motor 3.41 and the rack member 3.42.

[0109] Refer to Figure 26 and Figure 28 , a clearance area 3.10 is configured in the middle of the work support 3.1, the work motor 3.4 and the rack member 3.42 are respectively arranged on both sides of the work support 3.1 and coupled through the clearance area 3.10.

[0110] See Figure 27 , an upper portion of the work support 3.1 is configured with a first guide rod mounting portion 3.16 for fixing upper ends of one or more guide rods 3.6, a lower end of the work support 3.1 is bent to form a second guide rod mounting portion 3.17 for fixing lower ends of one or more guide rods 3.6.

[0111] In some embodiments, the work component 3 further comprises a first work housing 3.1' and a second work housing 3.2' which are relatively joined, the first work housing 3.1' and the second work housing 3.2' are relatively arranged on both sides of the second guide rail 2c.2, and the first work housing 3.1' is configured with a work area 3.10' for the work fixture 3.3 to move.

[0112] The work fixture 3.3 may specifically include a clamping base 3.31, a pushing block 3.32, a pushing rod 3.33 and a rotating member 3.34, the clamping base 3.31 is configured with a clamping channel 3.30, the pushing block 3.32 is movably installed in the clamping channel 3.30, an inner end of the pushing rod 3.33 is rotatably connected with the pushing block 3.32 and passes through the clamping base 3.31 in threaded fit, the rotating member 3.34 is installed on an outer end of the pushing rod 3.33, the pushing rod 3.33 can adjust the relative position of the pushing block 3.32 through the rotating member 3.34 to adjust the size of the clamping channel 3.30, so as to realize clamping or loosening of a work tool, such as a drawing pen.

[0113] In some embodiments, the opposing surfaces of the push block 3.32 and the clamping channel 3.30 are constructed with a V-shaped structure to achieve clamping and positioning of any working tool.

[0114] In some embodiments, the clamp 3.31 is a closed structure, and the push block 3.32 is held in place in the clamping channel 3.30 by the protrusions 3.321 on both sides of its upper end.

[0115] In some embodiments, the support base 1.2 adopts a one-piece molded structure.

[0116] In some embodiments, the support base 1.2 is integrally injection molded.

[0117] In some embodiments, the support base 1.2 has a cavity with a lower opening (not shown in the figure), and a counterweight (not shown in the figure) is provided inside the cavity; the counterweight is fixedly connected to the support base 1.2 by tightly fitting the inner wall of the cavity, or the counterweight is fixedly connected to the support base 1.2 inside the cavity by adhesive, or the counterweight is fixedly connected to the first slide rail 1.11 by fasteners. The counterweight improves the stability of the first guide rail bracket 1.

[0118] In some embodiments, the counterweight is inserted into the cavity through the lower opening of the cavity.

[0119] In some embodiments, the support base 1.2 is formed by injection molding on the outside of the counterweight.

[0120] See Figures 1 to 28Another embodiment of the drawing machine of this application includes: a first guide rail bracket 1 having a first guide rail 1.1 and support seats 1.2 constructed at both ends of the first guide rail 1.1, and first slide rails 1.11 constructed on opposite sides of the first guide rail 1.1; a main unit 2 including: a main unit pulley 2a.2 coupled to the slide rail 1.11; a first driver 2a.3; a first transmission member 2a.4 mounted along the first guide rail 1.1 and coupled to the first driver 2a.3; and a first part 2a passing through the main unit pulley 2a. 2. Assembled onto a first guide rail 1.1; a second guide rail 2c.2 perpendicular to the first guide rail 1.1; a second driver 2c.3; a second transmission component 2c.4 coupled along the second guide rail 2c.2 and to the second driver 2c.3; a housing 200 having a wire storage channel 2.20' open along the direction of the second guide rail 2c.2; a circuit module e; a main unit 2; and a working unit 3 having: a vertically movable working clamp 3.3; and a working drive mechanism 3.4 for driving the vertical movement of the working clamp 3.3. The working unit 3 and the circuit module e are electrically connected by a self-retracting wire, and one end of the self-retracting wire is located within the wire storage channel 2.20'. When the working unit 3 moves along the direction of the main unit 2, the self-retracting wire can be stored in the wire storage channel 2.20'. Therefore, the drawing machine of this solution can reduce the volume of the filament L1 during use. The filament between the working component 3 and the circuit module e can be wound and unwound through the filament storage channel 2.20'. When the working component 3 is close to the main unit 2, the filament will not bend or tangle, thus eliminating the need for an additional filament protection structure. In some embodiments, the self-retracting filament is a spiral, and the filament storage channel 2.20' is constructed on the side of the second guide rail 2c.2. The dimensions of the filament storage channel 2.20' are configured to be larger than the diameter of the spiral coil of the self-retracting filament.

[0121] See Figures 29 to 37The drawing machine of another embodiment shown includes: a first guide rail bracket 1 having a first guide rail 1.1 and support bases 1.2 constructed at both ends of the first guide rail 1.1; a main unit component 2 including: a main unit pulley 2a.2 coupled to the slide rail 1.11; a first driver 2a.3; a first transmission member 2a.4 mounted along the first guide rail 1.1 and coupled to the first driver 2a.3; a first part 2a assembled to the first guide rail 1.1 via the main unit pulley 2a.2; a second guide rail 2c.2 perpendicular to the first guide rail 1.1, the upper side of the second guide rail 2c.2 having a wire storage groove 2c.20 extending along the length direction; a second driver 2c.3; a first transmission member 2a.4 mounted along the second guide rail 2c.2 and coupled to the first driver 2a.3; and a first transmission member 2a.4 mounted along the second guide rail 2c.2 and coupled to the first driver 2a.3. The actuator 2c.3 is coupled to a second transmission component 2c.4; a circuit module e is configured in the main unit 2; and a working component 3 has: a vertically movable working clamp 3.3; and a working drive mechanism 3.4 for driving the vertical movement of the working clamp 3.3. The working component 3 and the circuit module e are electrically connected by a sheathed wire L1. The sheathed wire L1 is fixed at a predetermined length from the inner end of the second guide rail 2c.2 to a wire storage groove 2c.20 constructed in the second guide rail 2c.2. One end of the sheathed wire L1 connected to the working component 3 is located on the side close to the outer end of the second guide rail 2c.2. When the working component 3 moves relative to the main unit 2, the free part of the sheathed wire L1 can be stored or pulled out along the wire storage groove 2c.20.

[0122] The sheathed cable L1 is a cable consisting of multiple independent cores, used to power and communicate with the operating component 3, such as sensor communication.

[0123] By using sheathed wire L1 and wire storage groove 2c.20 to store and release part of the wire segment, the sheathed wire L1 can be self-stored and flipped during the movement of the working part 3. The structure is simple and highly reliable.

[0124] See Figures 34 to 37 In one embodiment, the sheathed wire L1 is fixed to the wire storage groove 2c.20 by the wire pressing block L2. The wire storage groove 2c.20 is a V-shaped groove or inverted trapezoidal groove that forms the upper part of the second guide rail 2c.2 and is connected to the upper side. The wire pressing block L2 is constructed to fit the shape of the wire storage groove 2c.20 in a V-shape or inverted trapezoidal shape. The wire pressing block L2 is inserted into the wire storage groove 2c.20 from the end of the second guide rail 2c.2.

[0125] Figures 34 to 37In the illustrated embodiment, the wire clamping block L2 is in the shape of an inverted trapezoid. A recess is provided on the lower side of the wire clamping block L2 to mate with the sheathed wire L1. The two side corners L21 of the wire clamping block L2 mate with the two side corners of the wire storage groove 2c.20 to prevent the wire clamping block L2 from vertically disengaging from the wire storage groove 2c.20. The two side corners L21 of the wire clamping block L2 can be provided with protruding edges L211, which contact the top of the two side corners of the wire storage groove 2c.20. This design reduces the contact area between the wire clamping block L2 and the wire storage groove 2c.20, facilitating installation.

[0126] The outer end of the second guide rail 2c.2 is equipped with an end component 2c.41'. After removing the end component 2c.41', the pressure block L is installed.

[0127] In some embodiments, the drive wheel 2c.41 is mounted on the end member 2c.41', which is specifically connected to the outer end of the second guide rail 2c.2 via a plug-in structure.

[0128] Since the sheathed wire L1 exerts a small axial force on the wire clamping block L2, it is only necessary for the wire clamping block L2 to have a tight fit with the wire storage groove 2c.20, and positioning can be achieved by using friction.

[0129] In some embodiments, the circuit module e is arranged within the housing 200 such that the circuit module e is not arranged on the support 1.2 or directly on the outer surface of the host component 2.

[0130] In some embodiments, the circuit module e includes a control device e21 configured to be operable from outside the housing 200.

Specifically, the main unit pulley 2a.2 can be connected to the first substrate 2a.1 via a bolt connector 2a.21.

[0134] In some embodiments, the main control circuit e1 is configured with a clearance notch e10 corresponding to the first driver 2a.3.

[0135] See Figure 9 and Figure 23 It also includes a reset detection component k1 for detecting the reset of the working component 3. The reset detection component k1 is configured in the host component 2. When the working component 3 approaches the host component 2, the reset detection component k1 is triggered, enabling the circuit module e to obtain the position information of the working component 3. Figure 9 and Figure 23 In the illustrated embodiment, the reset detection component k1 is mounted on the first substrate 2a.1. The reset detection component k1 is a micro switch and is equipped with a contact k11. The first housing 2.1 is configured with a trigger clearance port k10 corresponding to the contact k11. The second working housing 3.2' (or the first working housing 3.1') of the working component 3 is configured with a trigger protrusion 3.21'. When the working component 3 approaches the host component 2, the trigger protrusion 3.21 presses against the contact k11 from the trigger clearance port k10 to trigger the reset detection component k1.

[0136] See Figure 23 , Figure 27 and Figure 28 The working component 3 is equipped with a detection component k3 for detecting the position of the working fixture 3.3. When the working fixture 3.3 moves upward to a preset height, the detection component k3 is triggered, enabling the circuit module e to obtain the position information of the working fixture 3.3. (See attached...) Figure 23 , Figure 27 and Figure 28 In the embodiment shown, the trigger detection component k3 is mounted on the working support 3.1, and the connecting member 3.5 is equipped with a trigger part 3.5'. When the working fixture 3.3 moves upward to a preset height, the trigger part 3.5' triggers the detection component k3. The detection component k3 is an existing detection component, such as a micro switch.

[0137] See Figure 17 and Figure 19The first part 2a is equipped with a position detection component k2 for detecting its position information. One of the support bases 1.2 is constructed with a trigger part k22 for triggering the detection component k2. When the detection component k2 is moved and comes into contact with it, the trigger part k22 is triggered, enabling the circuit module e to obtain the position information of the first part 2a. One embodiment of the detection component k2 is a micro switch, which is equipped with a contact k21 that is triggered by the trigger part k22.

[0138] See Figure 1 , Figure 20 and Figure 21 In one embodiment of the first guide rail bracket 1, two support seats 1.2 have positioning recesses 1.20 on opposite sides to fit the two ends of the first guide rail 1.1. Each support seat 1.2 has one or more connecting holes 1.24 communicating with the positioning recesses 1.20. Screws 1.23 pass through the connecting holes 1.24 from the outside and connect to threaded holes at the ends of the first guide rail 1.1, thus fixing the first guide rail 1.1 to the support seats 1.2. In some embodiments, the support seats 1.2 have mounting recesses on their outer sides, and the one or more connecting holes 1.24 are located in the mounting recesses. A decorative cover 1.22 is also provided to cover the mounting recesses. This design improves the aesthetics of the first guide rail bracket 1.

The system comprises: a guide rail 1.1 and a second guide rail 2c.2 perpendicular to it; a second driver 2c.3 mounted on the second substrate 2c.1; a second transmission member 2c.4 coupled along the second guide rail 2c.2 and to the second driver 2c.3; a circuit module e arranged on the main unit 2 such that the circuit module e is not arranged on the support base 1.2; a working unit 3 having: a working bracket 3.1 coupled to the second guide rail 2c.2 via a working pulley 3.2; a working clamp 3.3 vertically movable relative to the bracket 3.1; a working drive mechanism 3.4 for driving the working clamp 3.3 vertically; and one or more quick locking mechanisms 4 for locking the second substrate 2c1 and the first substrate 2a1 after the second part 2c is mounted on the upper side of the first part 2a.

[0156] The quick-locking mechanism 44 includes a locking rod 4.1. The lower part of the locking rod 4.1 has a locking rod threaded portion 4.11. The locking rod 4.1 passes through the first control mounting hole 4.12 constructed in the first substrate 2a.1 from the upper part of the second part 2c and connects with the threaded hole 4.2 constructed in the first substrate 2a.1. The locking rod 4.1 acts on the second guide rail 2c.2 or the second substrate 2c.1, such as a positioning limiting structure of the locking rod 4.1, such as a boss with a diameter larger than the head or other parts of the locking rod 4.1. When the locking rod threaded portion 4.11 of the locking rod 4.1 locks into the threaded hole 4.2 of the first substrate 2a.1, the limiting structure of the locking rod 4.1 abuts against the edge of the corresponding hole in the second guide rail 2c.2 or the second substrate 2c.1, thereby locking the first part 2a and the second part 2c.
