[0048] The present application mainly proposes a control method of a wire binding device, mainly applied to wire binding of a workpiece 100, and the workpiece 100 is a high-voltage controller.

[0049] The specific structure of the control method of the wire binding device will be mainly described below.

[0050] Reference Figures 1 to 8 In the embodiments of the present application, the control method of the wire binding device comprises:

[0051] An installation rack 1 is provided with a mounting position 13 configured to place a workpiece 100, and an avoiding position is provided obliquely above the mounting position 13;

[0052] A pressing driving member 2, a transmission assembly 3 and a pressing assembly are installed on the installation rack 1, and the pressing driving member 2 and the transmission assembly 3 are located below the mounting position 13;

[0053] The pressing assembly includes a connecting rod 41 and a pressing part 42 provided on the upper end of the connecting rod 41, the connecting rod 41 is in sliding connection with the installation rack 1, and the pressing part 42 is located on the upper side of the mounting position 13, so that the pressing part 42 moves to the mounting position 13 or the avoiding position with the movement of the connecting rod 41; the pressing driving member 2 is used to drive the transmission assembly 3, and the transmission assembly 3 is used to drive the connecting rod 41 to move between the mounting position 13 and the avoiding position;

[0054] A wire binding device is provided adjacent to the installation rack 1, and is used to weld one end of a metal wire to a terminal block of the workpiece 100 and the other end to a printed circuit board of the workpiece 100, so that the terminal block and the printed circuit board are electrically connected;

[0055] The control method of the wire binding device includes:

[0056] The current position of the pressing part 42 is obtained, and it is determined that the pressing part 42 is located in the avoiding position;

[0057] The workpiece 100 is placed on the mounting position 13 from top to bottom, the pressing assembly is driven by the pressing driving member 2 and the transmission assembly 3 to move obliquely downward, so that the pressing part 42 moves to the mounting position 13 and is pressed on the surface of the workpiece 100;

[0058] The wire binding device is controlled to bind the wire;

[0059] It is determined that the wire binding is completed, the pressing assembly is controlled to move obliquely upward, so that the pressing part 42 moves to the avoiding position, and the workpiece 100 is taken out from bottom to top.

[0060] Specifically, in the embodiment, the binding device can have many forms, including a mounting frame 1, a pressing driving element 2, a transmission assembly 3, a pressing assembly, and a binding device. The overall shape of the mounting frame 1 can be a rectangular body, a square body, or a cylindrical body, and is not specifically limited here. The mounting frame 1 can be formed by splicing multiple parts or can be integrally formed. In this embodiment, the mounting frame 1 is formed by splicing multiple parts. The top of the mounting frame 1 is provided with a mounting position 13 and a clearance position. The clearance position is spaced apart from the mounting position 13 and is located outside the orthogonal projection of the mounting position 13. The height of the clearance position can be higher than or flush with the mounting position 13. In this embodiment, the clearance position is higher than the mounting position 13. The mounting position 13 is used to mount a workpiece 100. The mounting position 13 can be a mounting groove or a mounting notch, and is not specifically limited here.

[0061] The pressing driving element 2, the transmission assembly 3, and the pressing assembly are all mounted on the mounting frame 1. The pressing driving element 2 and the transmission assembly 3 are both located below the mounting position 13. The type of the pressing driving element 2 can be a pneumatic cylinder, a hydraulic cylinder, or a linear motor, and is not specifically limited here. In this embodiment, the pressing driving element 2 is a pneumatic cylinder. The pressing driving element 2 is located at the bottom of the mounting frame 1, and the output shaft of the pressing driving element 2 extends vertically. The transmission assembly 3 is movably arranged on the mounting frame 1 between the pressing driving element 2 and the top of the mounting frame 1. The lower side of the transmission assembly 3 is connected to the output shaft of the pressing driving element 2, so that the pressing driving element 2 can drive the transmission assembly 3 to move up and down.

[0062] The pressing assembly comprises a connecting rod 41 and a pressing part 42 arranged on the upper end of the connecting rod 41. The connecting rod 41 is slidably connected with the mounting frame 1, and the length of the connecting rod 41 is arranged on the mounting frame 1 along the vertical direction of the mounting frame 1. Meanwhile, the pressing part 42 is located on the upper side of the mounting position 13. The sliding direction of the connecting rod 41 with the mounting frame 1 can be various, such as arranging a guide groove 14, a guide channel or a guide shaft on the mounting frame 1. For example, when the guide groove 14 is arranged on the mounting frame 1, the depth of the guide groove 14 is arranged along the vertical direction of the mounting frame 1, and the length direction of the guide groove 14 is arranged towards the mounting position 13. The connecting rod 41 is slidably arranged in the guide groove 14, so that the upper part of the connecting rod 41 can swing along the length direction of the guide groove 14, and the connecting rod 41 can move up and down along the depth direction of the guide groove 14. Thus, when the connecting rod 41 swings towards the mounting position 13 and moves downwards, the pressing part 42 can move to the mounting position 13 along with the movement of the connecting rod 41, and press the workpiece 100 located in the pressing position. When the connecting rod 41 moves upwards and swings away from the mounting position 13, the pressing part 42 moves away from the mounting position 13.

[0063] When the guide shaft is arranged on the mounting frame 1, the connecting rod 41 is provided with a sliding groove extending along the length direction of the connecting rod 41. The connecting rod 41 is arranged on the mounting frame 1 in a downward inclined manner, and the inclined direction of the connecting rod 41 is arranged towards the mounting position 13. Meanwhile, the sliding groove is slidably connected with the guide groove 14, so that the connecting rod 41 can rotate around the guide shaft and move vertically along the mounting frame 1. Since the connecting rod 41 is inclined towards the mounting position 13, the sliding groove of the connecting rod 41 and the upper and lower ends of the connecting rod 41 are not located at the same point on the orthogonal projection of the mounting position 13. When the connecting rod 41 is driven to move upwards, the connecting rod 41 rotates around the guide shaft during the upward movement. Thus, the connecting rod 41 forms a lever, the position where the sliding groove cooperates with the guide shaft forms a support point, the lower end of the connecting rod 41 forms a power arm, and the upper end of the connecting rod 41 forms a resistance arm. During the upward movement of the connecting rod 41, the distance between the guide shaft and the lower end of the connecting rod 41 becomes shorter, so that the pressing part 42 can move to the mounting position 13 and press the surface of the workpiece 100.

[0064] When the connecting rod 41 is driven to move downward, the connecting rod 41 moves downwardly and rotates around the guide shaft during the movement, so that the pressing part 42 can move to the avoiding position, and the distance between the pressing part 42 and the guide shaft gradually shortens during the movement of the pressing part 42 to the avoiding position. Thus, the workpiece 100 can be prevented from being interfered by the pressing part 42 when the workpiece 100 is placed or taken out.

[0065] When the guide channel is formed on the mounting rack 1 and extends downwardly and upwardly, the upper opening of the guide channel is adjacent to the outer edge of the mounting position 13 in the orthographic projection of the mounting position 13, and the lower opening of the guide channel is located in the mounting position 13. Thus, when the connecting rod 41 is in sliding cooperation with the guide channel and is driven to move downward, the pressing part 42 can move downward with the connecting rod 41 and press the workpiece 100 in the mounting position 13. When the connecting rod 41 moves upward, the pressing part 42 moves upwardly and enters the avoiding position. Thus, the workpiece 100 can be prevented from being interfered by the pressing part 42 when the workpiece 100 is placed in the mounting position 13 or taken out from the mounting position 13.

[0066] The binding device is arranged adjacent to the mounting rack 1, so that the binding device can bind the workpiece 100 on the mounting rack 1. Before the workpiece 100 is bound, the workpiece 100 is installed in the mounting position 13. The workpiece 100 can be installed in the mounting position 13 manually or by a mechanical arm, which is not limited herein. Before the workpiece 100 is installed, the control system of the binding device acquires the current position of the pressing part 42 and determines that the pressing part 42 is in the avoiding position. The pressing part 42 can be determined to be in the avoiding position by a position sensor, a limit switch or the stroke of the connecting rod 41, which is not limited herein. After the pressing part 42 is determined to be in the avoiding position, the workpiece 100 is installed in the mounting position 13. After the workpiece 100 is installed in the mounting position 13, the workpiece 100 can be determined to be in the mounting position 13 or not. When the workpiece 100 is not determined to be in the mounting position 13, the next step can be executed by a time delay, for example, after the workpiece 100 is placed in the mounting position 13, the next step can be executed after 1 second. When the workpiece 100 is determined to be in the mounting position 13, the workpiece 100 can be determined to be in the mounting position 13 by a pressure sensor or a light sensor.

[0067] When the workpiece 100 reaches the installation position 13, the pressing assembly is driven to move downward by pressing the driving member 2 and the transmission assembly 3, so that the pressing portion 42 moves downward with the movement of the connecting rod 41 and presses the workpiece 100 in the installation position 13. When the pressing portion 42 presses the workpiece 100, the pressing force between the pressing portion 42 and the workpiece 100 can be detected or not. When the pressing force between the pressing portion 42 and the workpiece 100 is detected, a pressure sensor can be arranged on the side of the pressing portion 42 facing the workpiece 100, and the pressing position is determined by acquiring the pressure of the pressure sensor. When the pressing force between the pressing portion 42 and the workpiece 100 is not detected, the pressing position of the workpiece 100 can be confirmed by the contraction limit of the pressing driving member 2.

[0068] When the pressing portion 42 completes the pressing of the workpiece 100, the binding device is controlled to bind the wire, and after the binding device completes the binding, the completion information of the binding device is acquired. After the binding device completes the binding, the pressing assembly is driven to move obliquely upward by the pressing driving member 2 and the transmission assembly 3, and during the upward movement of the pressing assembly, the pressing portion 42 releases the pressing of the workpiece 100 and moves towards the avoiding position. When the pressing portion 42 reaches the preset position, the workpiece 100 can be taken out, and at this time, the pressing portion 42 will not interfere with the workpiece 100.

[0069] The control method of the binding device of the application is provided by arranging the installation position 13 on the top of the mounting rack 1, arranging the pressing driving member 2, the transmission assembly 3 and the pressing assembly on the mounting rack 1, and arranging the pressing driving member 2 and the transmission assembly 3 below the installation position 13, and the pressing driving member 2 is used to drive the transmission assembly 3 to move up and down. The pressing assembly includes a connecting rod 41 and a pressing portion 42, the connecting rod 41 is movably arranged on the mounting rack 1, one end of the connecting rod 41 is located on the top of the mounting rack 1, and the pressing portion 42 is arranged on the end of the connecting rod 41 located on the top of the mounting rack 1. The other end is rotationally connected with the transmission assembly 3, so that when the transmission assembly 3 moves up and down, the transmission assembly 3 can drive the connecting rod 41 to move obliquely upward, so that the pressing portion 42 can move between the installation position and the avoiding position. Therefore, before the workpiece 100 is placed in the installation position 13, the current position of the pressing portion 42 is acquired first, the workpiece 100 is placed in the installation position 13 when the pressing portion 42 is in the avoiding position, and when the workpiece 100 is taken out after the binding is completed, the pressing portion 42 moves towards the avoiding position and moves to the avoiding position when the pressing assembly is driven to move obliquely upward by the pressing driving member 2 and the transmission assembly 3. Therefore, when the workpiece 100 is taken out and placed, the workpiece will not be interfered by the pressing portion 42, and the convenience of use is improved.

[0070] It should be noted that the binding device further comprises a position sensor arranged on the top of the mounting frame 1, and the position sensor is used to detect the position of the pressing part 42; before the step of taking out the workpiece 100, the position sensor is further used to obtain the position information of the pressing part 42, and it is determined that the pressing part 42 is located in the avoiding position.

[0071] The light sensor is arranged in the avoiding position, so that when the pressing part 42 enters the avoiding position, the light sensor can obtain the position information of the pressing part 42. In order to be safer when taking out the workpiece 100, the current position of the pressing part 42 is obtained before taking out the workpiece 100, and the workpiece 100 is taken out when it is determined that the pressing part 42 enters the avoiding position, so as to prevent the workpiece 100 from being damaged by colliding with the pressing part 42 when the workpiece 100 is taken out.

[0072] In some examples, as shown in Figure 1 and Figure 4 The binding device further comprises a pressure sensor arranged on the pressing part 42, and the pressure sensor is used to collect the pressing force of the pressing part 42 on the workpiece 100; before the step of controlling the binding device to bind, the current pressing force of the pressing part 42 on the workpiece 100 is obtained, and it is determined that the current pressing force is greater than or equal to the preset pressing force; and the binding device is controlled to bind.

[0073] The pressure sensor is arranged on the lower side of the pressing part 42, so that when the pressing part 42 presses the workpiece 100, the side of the pressure sensor away from the pressing part 42 can abut against the pressure sensor, so that the pressure sensor can collect the pressing force of the pressing part 42 on the workpiece 100. In order to avoid that the workpiece 100 moves on the mounting position 13 during the binding process, causing the workpiece 100 to be defective, the current pressing force of the pressing part 42 on the workpiece 100 is obtained before binding, and the current pressing force is compared with the preset pressing force. When the current pressing force is less than the preset pressing force, the workpiece 100 may be loose during the binding process, at which time the connecting rod 41 needs to be controlled to continue to move downward to increase the pressing force of the pressing part 42 on the workpiece 100, until the pressing force of the pressing part 42 is greater than or equal to the preset pressing force, and then the binding is performed. In this way, the pressing force of the pressing part 42 on the workpiece 100 is avoided to be insufficient, which may cause the workpiece 100 to deviate during the binding process.

[0074] In some examples, as shown in Figures 1 to 3 and Figure 5As shown, the mounting rack 1 comprises two spaced support plates and a panel 12 arranged on the upper part of the two support plates, the panel 12 is provided with a guide groove 14 and the mounting position 13, the guide groove 14 penetrates the upper and lower sides of the panel 12, the length direction of the guide groove 14 is arranged towards the mounting position 13, the guide groove 14 is in sliding fit with the connecting rod 41, so that the connecting rod 41 can move up and down in the guide groove 14 and move along the length direction of the guide groove 14;

[0075] The pressing assembly further comprises a first guide 43 and a second guide 44, the radial diameters of the first guide 43 and the second guide 44 are greater than the groove width of the guide groove 14, the first guide 43 is arranged at one end of the connecting rod 41 connected with the pressing part 42, the first guide 43 is in sliding fit with the upper side of the panel 12, so that when the transmission assembly 3 drives the connecting rod 41 to move downward, the first guide 43 abuts against the upper side of the panel 12 to guide the pressing assembly into the mounting position 13; the second guide 44 is arranged at the lower part of the connecting rod 41, the second guide 44 is in sliding fit with the lower side of the panel 12, so that when the transmission assembly 3 drives the connecting rod 41 to move upward, the second guide 44 cooperates with the lower side of the panel 12 to guide the pressing assembly to move to the avoiding position.

[0076] The mounting rack 1 comprises two spaced support plates and a panel 12 arranged on the upper part of the two support plates. The panel 12 is provided with a guide groove 14, the depth direction of the guide groove 14 penetrates the upper and lower sides of the panel 12, so that when the connecting rod 41 is arranged in the guide groove 14, the two ends of the connecting rod 41 can protrude from the upper and lower sides of the panel 12 of the guide groove 14, in order to better drive the connecting rod 41 to move up and down, the lower end of the connecting rod 41 is rotationally connected with the moving assembly. In order to enable the connecting rod 41 to drive the pressing part 42 to approach and move away from the mounting position 13, the groove length of the mounting groove needs to be arranged towards the mounting position 13, so that when the connecting rod 41 moves along the length direction of the guide groove 14, the pressing part 42 can enter the mounting position 13 or exit and move away from the mounting position 13 along with the movement of the connecting rod 41.

[0077] The pressing assembly further comprises a first guide 43 and a second guide 44. The first guide 43 is arranged at one end of the connecting rod 41 connected with the pressing part 42, and is located at the lower side of the pressing part 42 and outside the guide groove 14. In order to better guide the connecting rod 41 to move along the length direction of the guide groove 14, when the transmission assembly 3 moves downward, the surface of the first guide 43 needs to be in sliding fit with the upper side of the panel 12 after the connecting rod 41 moves to a certain height. Thus, due to the inclined arrangement of the connecting rod 41, when the transmission assembly 3 moves downward, the surface of the first guide 43 is in sliding fit with the upper side of the panel 12, so that the first guide 43 can guide the connecting rod 41 to move on the guide groove 14 towards the mounting position 13, and the pressing part 42 enters the mounting position 13 along with the movement of the connecting rod 41 and presses the workpiece 100 located in the mounting position 13, so as to achieve the purpose of pressing the workpiece 100. It should be noted that in order to better press the workpiece 100, the mounting position 13 needs to be located on the panel 12, and the height of the mounting position 13 is greater than the radial diameter of the first guide 43, so as to prevent the pressing force of the pressing part 42 from being insufficient due to the excessive height of the first guide 43.

[0078] The second guide 44 is arranged at the lower end of the connecting rod 41 and is located outside the guide groove 14, and the distance between the second guide 44 and the first guide 43 needs to be greater than twice the thickness of the panel, so as to prevent the distance between the second guide 44 and the first guide 43 from being too short, causing the connecting rod to be difficult to move upward and along the length direction of the guide groove. When the transmission assembly 3 moves upward, after the connecting rod 41 moves upward to a certain height, the surface of the second guide 44 needs to be in sliding fit with the lower side of the panel 12, so that the connecting rod 41 moves along the length direction of the guide groove 14 under the action of the second guide 44 and drives the pressing part 42 to move to the avoiding position, so that the pressing part 42 can move to the avoiding position after releasing the pressing on the workpiece 100, and the workpiece 100 is avoided. Thus, when the workpiece 100 is taken and placed, the workpiece 100 is no longer interfered, and the convenience of taking and placing the workpiece 100 is improved.

[0079] In some examples, as shown in Figure 1 、 Figures 4 to 7 , the mounting position 13 is a mounting groove, the panel 12 has an avoiding groove 15, the groove width of the avoiding groove 15 is greater than the radial diameter of the first guide 43, the length direction of the guide groove 14 has a pressing section 141 and an avoiding section 142, the pressing section 141 is arranged in the recessed area of the avoiding groove 15, and the avoiding section 142 is in communication with the avoiding groove 15.

[0080] The mounting position 13 is a mounting groove, which is arranged on the upper side of the panel 12. In order to better press the workpiece 100, the upper side of the panel 12 is also provided with a clearance groove 15, which is arranged adjacent to the mounting groove, and the groove width of the clearance groove 15 is greater than the radial diameter of the first guide 43, so that the first guide 43 can enter the clearance groove 15. In the length direction of the guide groove 14, the guide groove 14 has a pressing section 141 and a clearance section 142, the pressing section 141 is arranged adjacent to the mounting groove, and the pressing section 141 is arranged in the recessed area of the clearance groove 15. The clearance section 142 is in communication with the clearance groove 15, so that when the connecting rod 41 moves from the clearance section 142 to the pressing section 141 at the upper part, the first guide 43 enters the clearance groove 15 after entering the pressing section 141, and the connecting rod 41 moves downward after the first guide enters the clearance groove 15. The connecting rod 41 moves downward during the movement, so that the pressing part 42 can better press the workpiece 100, and prevent the first guide 43 from interfering with the pressing of the workpiece 100 by the pressing part 42. When the first guide 43 exits the clearance groove 15, the connecting rod 41 moves upward and away from the mounting position 13, while driving the pressing part 42 upward and away from the mounting position 13, when the first guide 43 enters the clearance section 142, the pressing part 42 moves towards the clearance position, until the pressing part 42 enters the clearance position.

[0081] In some examples, as shown in Figure 4 and Figure 7 The clearance groove 15 has a guide wall 151 adjacent to the clearance section 142, which extends from the bottom of the clearance groove 15 to the groove of the clearance groove 15 in an arc transition.

[0082] In order to make the first guide 43 more smoothly enter and exit the clearance groove 15, the clearance groove 15 has a guide wall 151, which is located on one side of the clearance groove 15 adjacent to the clearance section 142, and the guide wall 151 extends from the bottom of the guide groove 14 to the groove of the guide groove 14 in an arc transition, so that the impact of the pressing part 42 on the workpiece 100 can be reduced when the first guide 43 enters and exits the clearance groove 15.

[0083] In some examples, as shown in Figures 1 to 5 The first guide 43 is spherical; and / or,

[0084] The second guide 44 is spherical.

[0085] In order to reduce the friction between the first guide 43 and the panel 12, the first guide 43 is provided in a spherical shape as a whole, so that when the first guide 43 in the spherical shape is in abutment with the panel 12, the friction between the first guide 43 and the panel 12 can be reduced. Similarly, in order to reduce the friction between the second guide 44 and the panel 12, the second guide 44 is provided in a spherical shape as a whole, so that when the second guide 44 in the spherical shape is in abutment with the panel 12, the friction between the second guide 44 and the panel 12 can be reduced.

[0086] In some examples, as shown in Figure 8 , the length direction of the pressing part 42 and the length direction of the connecting rod 41 form an angle α, the angle α is greater than or equal to 55° and less than or equal to 70°; and / or,

[0087] The number of pressing assemblies is multiple, and multiple pressing assemblies are arranged along the circumference of the mounting position 13.

[0088] In order to better press the workpiece 100, the length direction of the pressing part 42 and the length direction of the connecting rod 41 form an angle α, the angle α is greater than 55°, and the angle α is less than 55°. When the pressing part 42 and the workpiece 100 are in contact, the contact area between the pressing part 42 and the workpiece 100 is too small, resulting in poor pressing effect. At the same time, when the angle α is less than 55°, the length of the pressing part 42 needs to be longer, causing waste of the pressing part 42. The angle α needs to be less than 70°, so as to avoid that the angle α is too large, which causes the contact area between the pressing part 42 and the workpiece 100 to be too small when pressing, resulting in poor pressing effect.

[0089] It should be noted that in order to better press the workpiece 100, the surface of the pressing part 42 pressing the workpiece 100 is parallel to the surface of the workpiece 100, so that the contact area between the pressing part 42 and the workpiece 100 can be improved. The stability of the pressed workpiece 100 is improved.

[0090] In some examples, as shown in Figure 1 , Figure 2 and Figure 5 , the transmission assembly 3 includes a transmission plate 31 and a hinge plate 32 arranged on the transmission plate 31, the transmission plate 31 is connected with the output shaft of the pressing drive 2, and the hinge plate 32 is rotationally connected with the lower end of the connecting rod 41.

[0091] In order to improve the stability of the pressed workpiece 100, the number of pressing assemblies can be multiple, and multiple pressing assemblies are arranged along the circumference of the mounting position 13, so that when the pressing parts 42 of multiple pressing assemblies press the workpiece 100, the stability of the pressed workpiece 100 can be improved.

[0092] In some examples, as shown inFigure 5 and Figure 8 As shown in

[0093] The transmission assembly 3 comprises a transmission plate 31 and a hinged disc 32 arranged on the transmission plate 31, the transmission plate 31 is connected with the output shaft of the pressing driving member 2, and the hinged disc 32 is rotationally connected with the lower end of the connecting rod 41.

[0094] In some examples, as shown in Figure 1 , Figure 2 and Figure 5 The mounting rack 1 comprises two spaced apart support plates and a panel 12 arranged on the upper portions of the two support plates; the transmission assembly 3 comprises a transmission plate 31, and a locking hole 33 is formed in the end of the transmission plate 31 facing the support side plate 11;

[0095] The binding device further comprises a locking assembly 5, the locking assembly 5 comprises a locking driving member 51, a mounting seat 52 and a locking rod 53, the mounting seat 52 is mounted on the side of the support plate facing the transmission plate 31, the locking driving member and the locking rod 53 are both mounted on the mounting seat 52, the locking rod 53 is movably connected with the mounting seat 52, and the extension shaft of the locking driving member is connected with the locking rod 53, so that the locking driving member can drive the locking rod 53 to cooperate with the locking hole 33 or drive the locking rod 53 to exit the locking hole 33.

[0096] The mounting rack 1 comprises two spaced apart support plates and a panel 12 arranged on the upper portions of the two support plates. The transmission assembly 3 comprises a transmission plate 31, and a locking hole 33 is formed in the end of the transmission plate 31 facing the support side plate 11, the locking hole 33 can be located at both ends of the transmission plate 31, or can be located at one end of the transmission plate 31, and the embodiment is described by taking the case where the locking hole 33 is located at both ends of the transmission plate 31.

[0097] The locking assembly 5 comprises a locking driving member 51, a mounting seat 52 and a locking rod 53. The mounting seat 52 is mounted on the side of the support plate facing the transmission plate 31. The mounting seat 52 is provided with an assembly position, and the locking driving member 51 is mounted in the assembly position. The locking driving member 51 is a locking cylinder. The mounting seat 52 is provided with a limiting hole in communication with the assembly position. One end of the locking rod 53 is connected with the output shaft of the locking cylinder through the limiting hole, and the other end is matched with the locking hole 33. In this way, after the moving assembly drives the pressing assembly to press the workpiece 100, the moving assembly can be locked by the locking assembly to prevent the moving assembly from moving up and down, causing the pressing part 42 to loosen. In order to improve the convenience of locking the moving assembly by the locking assembly, the number of locking holes 33 is multiple, and the multiple locking holes 33 are vertically arranged. When the moving assembly moves up and down, the multiple locking holes 33 are respectively opposite to the limiting hole. In this way, when locking at a certain position is needed, the end of the locking rod 53 away from the mounting seat 52 is inserted into the limiting hole.

[0098] It should be noted that the mounting seat 52 is provided with a waist-shaped hole. When the mounting seat 52 is arranged on the mounting frame 1, the waist-shaped hole extends along the vertical direction of the mounting frame 1. The support plate is provided with a fixing hole. The binding device further comprises a fastener. One end of the fastener is matched with the fixing hole through the waist-shaped hole. In this way, the relative position of the mounting seat 52 and the support plate can be adjusted to adjust the position of the locking assembly locking the moving assembly.

The guide cylinder 61 is arranged on the mounting frame 1 and located at the bottom of the mounting frame 1. The guide rod 62 is arranged in the guide cylinder 61 in an extendable manner. At the same time, the guide rod 62 is connected with the transmission assembly 3. In this way, when the pressing driving member 2 drives the transmission assembly 3 to move up and down, the guide rod 62 moves with the transmission assembly 3 and corrects the displacement of the transmission assembly 3 through the cooperation of the guide rod 62 and the guide cylinder 61. In order to further protect the pressing driving member 2, the guide assembly has two guide cylinders 61 and two guide rods 62. The two guide cylinders 61 are arranged on both sides of the pressing driving member 2, and the two guide rods 62 are connected with the transmission plate 31. In this way, through the cooperation of the two guide rods 62 and the two guide cylinders 61, the deviation of the output shaft of the pressing driving member 2 is further prevented, and the service life of the pressing driving member 2 is improved.
