Description

Technical Field

[0001] The invention relates to the technical field of clip assembly machines, and in particular to a clamp seat of stationery clip automatic assembly equipment. Background Art

[0002] Clips are commonly used clamping tools in daily life. Clips come in a variety of shapes. Most of the existing clips with relatively regular shapes are assembled using a clip assembly machine. When assembled, the clips are pushed into the clamp seat along their height direction, and then torsion springs and pins are installed between the assembled clips. By using an assembly machine to assemble, the assembly efficiency of the clips is improved. However, there are still many clips with irregular shapes, especially those with non-flat sides and outer surfaces, which cannot be assembled using a clip assembly machine.

[0003] Stationery clips are a type of clip with irregular shapes. They are generally used to clamp papers, bills, etc., and the market demand is huge. Figure 1~2 As shown, the stationery clip is formed by two hinged clips, and a torsion spring is fixed between the two clips. The clip is generally stamped from a metal sheet, and the two ends of the clip are a clamping part and a pressing part respectively. The width of the clamping part is much larger than the width of the pressing part, so that the paper can be clamped with a better clamping effect. At the same time, the clamping part is provided with an arc section protruding toward the outer surface of the clip, and the outer surface of the clip is not a plane.

[0004] Existing stationery clips are all assembled by hand. During assembly, first, two clips are assembled together, the hinge holes on the clips are aligned, and then the torsion spring is installed between the two clips. Then, the pin is inserted into the two hinge holes on one side of the two clips, the inner hole of the torsion spring, and the two hinge holes on the other side of the two clips. Finally, the end of the rivet passing through the clip is punched to deform the end of the rivet and fix it on the clip.

[0005] During the manual assembly of the stationery clip, when the torsion spring is installed between the two clips, the torsion spring itself is in a compressed state, and the two elastic arms of the torsion spring will exert a large elastic force on the two clips, causing the two clips to tend to move away from each other, making it difficult for the four hinge holes on the two clips to be on the same axis, so that the clips and pins need to be adjusted many times before they can be installed in place, which is time-consuming and labor-intensive, and the assembly efficiency is low. In addition, in order to facilitate assembly, the matching clearance between the hinge hole of the clip and the pin is generally designed to be larger, resulting in low matching accuracy of the two clips, poor matching between the clamping parts of the two clips, and affected clamping effect.

[0006] The Chinese patent No. 201721921400.1 discloses a stainless steel clip seat, the side and outer surface of the clip are both flat, and the clamping part and the pressing part have the same width, so the clip can be easily fed in a side-lying manner through a vibrating plate and a feeding device. When feeding, the side and outer surface of the clip can be used as positioning surfaces, and the feeding device can be used to easily and accurately feed the clip into the seat along the height direction of the clip for splicing, positioning, and assembly.

[0007] However, since the width of the clamping part at the lower end of the stationery clip is much larger than the width of the pressing part at the upper end of the clip, the side surface is not flat, and the outer surface of the clip is also not flat. When the clip of the stationery clip is placed on its side, the clip will fall over, so the side surface of the clip cannot be used as a positioning and support surface during the transportation and positioning of the clip of the stationery clip, so that the clip can be pushed into the clamp seat along its height direction for assembly. The above structure of the stationery clip makes it impossible to use the above stainless steel clip clamp seat to position and assemble the stationery clip, so that the stationery clip can be assembled by an assembly machine. Summary of the invention

[0008] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a clamping seat for automatic assembly equipment of stationery clips, which can feed the clips into the clamping seat along the width direction of the clips, so as to position, splice and assemble the clips.

[0009] The above technical purpose of the present invention is achieved through the following technical scheme: a clamp seat of an automatic assembly device for stationery clips, including a seat body, characterized in that: a clip seat one and a clip seat two are arranged on the seat body, and a clip placement groove is arranged on the clip seat one and the clip seat two, the clip placement groove extends along the clip width direction, and the two clip placement grooves are respectively inclined to both sides of the vertical direction, and the outer end of the clip placement groove is a clip loading entrance, the clip seat two is located on one side of the clip seat one and can be moved vertically in the clip width direction, the two clip placement grooves are arranged opposite to each other and can be assembled to form a clip assembly cavity, the upper end of the clip assembly cavity is a torsion spring loading entrance, and the pressing part extends from the torsion spring loading entrance.

[0010] Through the above technical solution, the clip seat 1 is fixed on the seat body, and during assembly, a clip can be placed into the clip seat 1 along the width direction of the clip first. Then, the clip seat 2 is moved or rotated to the side away from the clip seat 1 along the direction perpendicular to the width of the clip by the driving device. After the movement of the clip seat 2, the distance between the clip placement grooves is roughly the distance between the two clip pivot ears, so that when the second clip is installed on the clip seat 2, the pivot ear of the second clip will not interfere with the pivot ear of the first clip. When the second clip is placed on the clip seat 2 on one side of the clip seat 1 along the width direction, the clip placement groove can accurately position the second clip. The clip placement groove extends along the width direction of the clip, and the lower end of the clamping part and part of the side surface of the clip can be used as positioning surfaces to achieve the purpose of accurate positioning. The two clip placement grooves are arranged facing each other. When the clip seat second moves laterally toward the clip seat under the action of the driving device or the resetting device, the two clip placement grooves can be assembled into a complete clip assembly cavity, and the two clips are also assembled at the same time, so that the hinge holes on the two clips are in an aligned state.

[0011] The second clip seat is movably arranged so that when the clip is installed into the second clip seat along its width direction, it will not be affected by the clip already installed on the first clip seat, and can be smoothly installed into the second clip seat. At the same time, since the two clips are spliced ​​together on the side faces, there will be no interference between the pivot ears of the clips. When driving the second clip seat to move, a driving device can be set on the base, or a driving device can be set on the assembly machine, so as to drive the second clip seat to approach or move away from the first clip seat.

[0012] When the clip seat 2 moves, it can slide sideways along a straight line direction, or it can swing sideways. When swinging sideways, the clip seat 2 is fixed to the back plate through a rotating shaft, and the two clip seats are spliced ​​together by rotating.

[0013] The outer surface of the clip rests against the surface of the clip placement groove, which can limit the opening angle of the two clips, so that the hinge holes on the clips can be in an aligned state when assembled. The two clip placement grooves are inclined to both sides of the vertical direction, respectively, and a section or the entirety of the outer surface of the clip can be used as a positioning surface, so that the clip can stably lean against the clip placement groove under the action of gravity. Therefore, by limiting a part or the entirety of the outer surface of the clip, the opening angle of the upper end of the clip is determined, so that the hinge holes on the pivot ears can be accurately aligned to facilitate the insertion of the pin. A torsion spring installation port is provided on the clip assembly cavity, and the pressing portion of the clip extends from the torsion spring installation port, so that the torsion spring can be installed from the upper end of the clip assembly cavity between the two clips.

[0014] Preferably, a guide groove and a guide block which cooperate with each other for guiding are arranged between the seat body and the second clip seat.

[0015] Through the above technical solution, the setting of the guide groove and the guide block can guide and limit the moving direction of the clip seat 2, so that the clip seat 2 can accurately cooperate with the clip seat 1 during the movement, so that the two clips can be accurately assembled.

[0016] Preferably, a stopper is provided on the side surface of the second clip seat, and a spring is provided between the stopper and the second clip seat.

[0017] Through the above technical solution, the setting of the spring can keep the clamp seat 2 and the clamp seat 1 in a tight state. When the clamp seat 2 moves to the side of the clamp seat 1 and the clamp is installed, the spring 2 can push the clamp seat 2 to return to the clamp seat 1, so that the two clamps are spliced.

[0018] Preferably, the guide block is rod-shaped and is arranged on two side surfaces of the clip seat, the guide groove is arranged on the stop block, and the guide block is inserted into the guide groove.

[0019] Through the above technical solution, the setting of the guide block and the guide groove can effectively limit the sliding direction of the second clip seat, so that when the second clip seat slides, the sliding direction is more accurate, so that the two clips can be accurately assembled.

[0020] Preferably, it also includes a driving rod, a driving groove is provided on the guide block, and a driving inclined surface is provided on the driving rod and / or the driving groove. The driving rod can be inserted into the driving groove to drive the guide block to slide in a direction away from the clip seat.

[0021] Through the above technical solution, the driving rod can be installed on the assembly machine during use, driven by the cylinder, and inserted into or withdrawn from the driving slot. When the driving rod is inserted into the driving slot, the guide block and the second clip seat slide away from the first clip seat through the driving surface, so that there is enough installation space between the second clip seat and the first clip seat, so that the clip can be placed on the second clip seat without interference. After the clip is placed on the second clip seat, the insertion rod retracts and withdraws from the driving slot, and the second clip seat slides toward the first clip seat under the action of the spring, so that the two clips on the first clip seat and the second clip seat are spliced.

[0022] Preferably, the clip placement groove includes a limiting groove at the lower end of the clamping part, and the lower end of the clamping part is inserted into the limiting groove at the lower end of the clamping part.

[0023] Through the above technical solution, the setting of the limit groove at the lower end of the clamping part can limit the position of the lower end of the clamping part of the clip, so that the position of the clip is more accurately positioned, and the position of the clip is not easily offset during the movement of the clip seat 2. The length of the clamping part inserted into the limit groove at the lower end of the clamping part can be determined according to actual conditions, and a small part of the lower end of the clamping part can be inserted into the limit groove at the lower end of the clamping part, or most of the lower end of the clamping part can be inserted into the limit groove at the lower end of the clamping part.

[0024] Preferably, a mounting cavity is provided on the clip seat 1 and / or the clip seat 2, and a magnetic component is installed in the mounting cavity.

[0025] Through the above technical solution, most of the clips are made of iron sheets, and the magnetic piece can adsorb the iron clip, so that the clip can be better fixed in the clip placement slot. The magnetic piece can be a magnet or an electromagnet.

[0026] Preferably, the mounting cavity is located outside the pivot mounting ear of the clip.

[0027] Through the above technical solution, the installation cavity is located there, so that the magnetic part can adsorb the upper and middle part of the clip, and cooperate with the limiting groove at the lower end of the clamping part to obtain a better fixing effect, so that the clip can be stably fixed in the clip seat.

[0028] Preferably, a limiting rod is installed on the seat body or the clip seat, and the limiting rod cooperates with the inner surface of the clamping portion of the clip to limit the position.

[0029] Through the above technical solution, for a clip that is not made of iron, the position of the clip can be further limited by the limit rod, so that the clip can be placed more firmly in the clip seat. At the same time, the limit rod is arranged inside the clip clamping part, which will not interfere with the installation of the torsion spring and the pin.

[0030] The number of the limiting rods can be one, which is located at the lower end of the pivot ear of the clip, or two, which are respectively located at the inner sides of the clamping ends of the two clips, and can also be three.

[0031] Preferably, the seat body includes a back plate, which is located outside the inner end of the clip placement groove, and the clip placement groove is perpendicular to the surface of the back plate.

[0032] Through the above technical solution, the setting of the back plate makes the clip seat structure simpler, and the clip placement groove can pass through the clip seat, with the back of the back plate as the limiting surface to limit the insertion depth of the clip.

[0033] Preferably, a pin punching groove is provided on the back plate, and the pin punching groove is located outside the pin hole.

[0034] Through the above technical solution, the setting of the back plate will not affect the stamping of the pins. When the clip is assembled, the punching head can normally pass through the back plate to stamp the pins.

[0035] Preferably, the back plate is provided with an ejection hole, and the clip seat 1 and the clip seat 2 are correspondingly provided with an ejection groove, the number of the ejection holes is two, and the two ejection holes are respectively opposite to the clamping parts of the two clips.

[0036] Through the above technical solution, the ejection hole is directly opposite to the clamping part. When the assembled clip needs to be ejected from the clamp seat, three ejector rods can be arranged on the assembly machine. The three ejector rods are respectively directly opposite to the two ejection holes and the pin punching groove, so as to push the pivot ears and the clamping part, thereby pushing the assembled clip out of the clamp seat. The setting of the ejection hole makes the overall force of the clip more uniform during the process of being ejected from the clamp seat, and there will be no jamming between the clip and the clamp seat, and the exit is smoother.

[0037] Preferably, two hollow grooves are provided on the back plate, and the clamping portion on one side of the pressing portion penetrates into the hollow grooves.

[0038] Through the above technical solution, the hollow groove is provided so that the side surface of the pivot ear of the clip directly contacts the surface of the back plate, thereby making the area of ​​the positioning surface between the clip and the back plate larger and obtaining a better positioning effect.

[0039] Preferably, a step groove is arranged on the outer side of the clip seat 1 and the clip seat 2, and the step groove includes a longitudinal surface 1, and the longitudinal surface 1 is in the same plane as the outer side surface of the clip pivot mounting ear.

[0040] Through the above technical solution, the setting of the step groove enables the end of the pin clamping device to be closer to the outer side of the pivot ear of the clip when the clip is assembled, thereby improving the position accuracy between the pin end and the pin hole on the pivot ear, making the pin pass through the pin hole more smoothly and less likely to get stuck.

[0041] Preferably, a limiting block is installed on the back plate, and an end of the limiting block protrudes out of the surface of the back plate and contacts with the surface of the pivot ear on the inner side of the clip in the clip seat.

[0042] With the above technical solution, when the clip is assembled, the pivoting ear of the second clip is located outside the pivoting ear of the first clip. Therefore, when the first clip is installed in the clip placement groove, an installation gap for inserting the pivoting ear of the second clip needs to be left between the pivoting ear on the inner side of the first clip and the back plate. When the back plate is not provided, the depth of the two clip placement grooves can be controlled to ensure that the pivoting ears of the two clips are not in the same plane, thereby avoiding jamming during assembly.

[0043] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting a clip seat one and a clip seat two, and making the clip seat two movably arranged, the clip can be loaded into the clip placement grooves in the clip seat one and the clip seat two along its width direction; when the clip seat two moves toward the clip seat one and collides with it, the two clips are spliced ​​together, and then the torsion spring and the pin can be installed by a clip assembly machine to realize the assembly of the clip whose side surface is not flat.

DETAILED DESCRIPTION

[0061] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0062] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0063] Embodiment 1

[0064] like Figure 3~Figure 5As shown, a clamp seat of a stationery clip assembly machine includes a seat body 1, and the seat body 1 includes a mounting portion 33 and a back plate 12. The back plate 12 is fixed to the rear side of the mounting portion 33, and the upper end of the back plate 12 protrudes from the upper surface of the mounting portion 33. When in use, the mounting portion 33 is fixed to the assembly machine by screws. A clip seat 1 2 and a clip seat 2 3 are arranged between the mounting portion 33 and the back plate 12. The clip seat 1 2 is fixed to one side of the front end of the back plate by screws. The clip seat 1 2 is fixed to the back plate 12 or the mounting portion 33. The clip seat 2 3 is located on one side of the clip seat 1 2 and can slide away from the clip seat 1 2. A clip placement groove 4 is respectively provided on the clip seat 1 2 and the clip seat 2 3, and the two clip placement grooves 4 are arranged opposite to each other and are respectively inclined to one side of the vertical plane. When the two clip placement grooves 4 are spliced ​​together, the upper ends of the two clips 27 are inclined to the left and right sides of the back plate 12 respectively. The clip placement groove 4 extends along the width direction of the clip 27, and the clip placement groove 4 is perpendicular to the surface of the back plate 12. A clip loading port 5 is provided at the front end of the clip placement groove 4. When the clip seat 1 2 and the clip seat 2 3 are assembled, the two clip placement grooves 4 are assembled to form a clip assembly cavity 6. A torsion spring loading port 7 is provided at the upper end of the clip assembly cavity 6, and the pressing portion 28 of the clip 27 extends from the torsion spring loading port 7, and the torsion spring is loaded between the pressing ends of the two clips 27 from the torsion spring loading port 7. The outer side surface of the clip 27 is in contact with a part of the surface of the clip placement groove 4, supporting and positioning the clip 27, so that the angle of inclination of the clip 27 to the outside in the vertical direction is determined, thereby ensuring that when the clip seat 1 2 and the clip seat 2 3 are assembled, the pin 31 holes of the two clips 27 can be aligned.

[0065] like Figure 6 and Figure 7 As shown, the clip placement groove 4 includes a limiting groove 8 at the lower end of the clamping part. The cross-sectional shape of the limiting groove 8 at the lower end of the clamping part is similar to the cross-sectional shape of the lower end of the clamping part 29. When the clip 27 is loaded into the clip placement groove 4 along the width direction of the clip 27 under the action of the feeding device of the assembly machine, the lower end of the clamping part 29 is inserted into the limiting groove 8 at the lower end of the clamping part. The limiting groove 8 at the lower end of the clamping part limits the position of the lower end of the clamping part 29, so that the position of the lower end of the clip 27 in the clip placement groove 4 is more accurate, and it is not easy to shift after placement, which can better improve the accuracy of the clip 27 when it is assembled.

[0066] The clip seat 1 2 and the clip seat 2 3 are also provided with an installation cavity 9, which is located outside the joint between the outer surface of the clip 27 and the surface of the clip placement groove 4, and a magnetic member 10 is installed in the installation cavity 9, and a magnet can be used for the magnetic member 10. The installation cavity 9 and the magnet can adsorb the iron clip 27, so that the clip 27 can be effectively fixed when placed in the clip placement groove 4, and will not affect the installation of the torsion spring and the pin 31.

[0067] A guide groove 16 and a guide block 17 are provided between the seat body 1 and the clip seat 2 3. The setting of the guide block 17 and the guide groove 16 can limit the moving direction of the clip seat 2 3, so that the clip seat 2 3 can slide in a direction perpendicular to the width direction of the clip during the sliding process, so that the clips 27 on the clip seat 1 2 and the clip seat 2 3 can be accurately assembled, and it is also convenient for the clip feeding device to load the clip into the clip placement groove.

[0068] A stopper 18 is provided on one side of the clip seat 2 3, and the stopper 18 is fixed on the mounting portion 33. A spring 19 is provided between the stopper 18 and the clip seat 2 3, and the spring 19 can push the clip seat 2 3 to move in the direction of the clip seat 1 2, and make the clip seat 2 3 collide and splice with the clip seat 1 2. The guide block 17 is rod-shaped and is provided on the side of the clip seat 2 3 facing away from the clip seat 1 2. The guide groove 16 is provided on the stopper 18, and the guide groove 16 is provided along the sliding direction of the clip seat 2 3, and the guide block 17 is inserted in the guide groove 16.

[0069] At the same time Fig.11 As shown, the clamp seat also includes a driving rod 20, a driving groove 21 is provided on the guide block 17, and corresponding through holes are provided on the back plate 12 and the stopper 18, so that the driving rod 20 can be inserted into the driving groove 21. A driving inclined surface 22 is provided on the driving rod 20, and the driving inclined surface 22 faces away from the clip seat 1 2. When the driving rod 20 is inserted into the driving groove 21, the driving inclined surface 22 contacts the side of the driving groove 21 away from the clip seat 1 2, thereby pushing the clip seat 2 3 to move in a direction away from the clip seat 1 2. When the clip 27 is placed on the clip seat 2 3, the driving rod 20 retracts and exits the driving groove 21. In this process, the clip seat 2 3 is reset under the action of the spring 19, so that the clip seat 2 3 moves in the direction of the clip seat 1 2 and contacts, so that the two clips 27 are spliced.

[0070] A pin punching groove 13 is provided on the back plate 12, and the pin punching groove 13 is located outside the pin 31 hole of the clip 27. When it is necessary to punch the end of the pin 31 inserted into the clip 27, a punch can be inserted from the pin punching groove 13 to punch the end of the pin 31. At the same time, a step groove 24 is provided on the upper part of the outer end of the clip seat 1 2 and the clip seat 2 3, and the clamping part 29 is located below the step groove 24 after the clip 27 is installed. The step groove 24 includes a longitudinal surface 1 25, and the longitudinal surface 1 25 is basically in the same plane as the outer side surface of the pivot ear 30 of the clip 27. This arrangement allows the end of the pin clamping device on the assembly machine to be closer to the pivot ear 30 of the clip 27, so that the pin clamping device can more accurately insert the pin 31 into the pin 31 hole of the clip 27.

[0071] The back plate 12 is also provided with two hollow grooves 23, and the clamping portion 29 on the inner side of the pressing portion 28 penetrates into the hollow grooves 23, so that the surface of the pivoting ear 30 on the inner side of the clip 27 can abut against the surface of the back plate 12. Compared with using the side of the clamping portion 29 as the abutting surface, this arrangement can obtain a larger contact area, thereby achieving a better positioning effect. Since the clip seat 23 is slidably arranged, the hollow groove 23 corresponding to the clip 27 on the clip seat 23 also expands along the sliding direction of the clip seat 23, so that the clamping portion 29 of the clip 27 on the clip seat 23 can always penetrate into the hollow groove 23.

[0072] A limit block 26 is installed on the back plate 12, and the outer end of the limit block 26 protrudes from the surface of the back plate 12. When a clip 27 is placed in the clip seat 12, the surface of the pivoting ear 30 of the clip 27 contacts the end surface of the limit block 26, thereby leaving a certain space between the pivoting ear 30 of the clip 27 and the back plate 12. During the assembly of the clip, the two pivoting ears 30 of one clip 27 are located inside the pivoting ear 30 of another clip 27. During assembly, the clip 27 with the pivoting ear 30 located inside is generally placed on the clip seat first, and then the other clip 27 is placed. The setting of the limit block 26 prevents the pivot ear 30 of the first clip 27 from directly fitting against the surface of the back plate 12, leaving a certain space between the two, so that after the pivot ear 30 of the second clip 27 is fitted and positioned against the surface of the back plate 12, when it moves toward the first clip 27, the pivot ear 30 of the second clip 27 can be inserted between the pivot ear 30 of the first clip 27 and the back plate 12, thereby realizing the splicing of the two clips 27.

[0073] In addition, the back plate 12 is also provided with ejection holes 14 for ejecting the assembled clip from the clip assembly cavity 6. There are two ejection holes 14, which are located outside the clip placement groove 4 and face the clamping portion 29 of the clip 27. The ejection holes 14 partially overlap with the hollow groove 23. The clip seat 1 2 and the clip seat 2 3 are provided with ejection grooves 15 corresponding to the ejection holes 14. The two ejection holes 14 and the pin punching groove 13 are arranged in a herringbone shape. When the assembled clip is ejected, three ejector rods pass through the pin punching groove 13 and the ejection holes 14, face the pivot ears 30 of the clip 27 and the end faces of the clamping portions 29 of the two clips 27, and thus push the clip out of the clip assembly cavity 6. The ejection holes 14 and the pin punching groove 13 are arranged in this way, so that the force on the clip is more uniform when it is pushed out, and the pushing process is smoother and less likely to get stuck.

[0074] Embodiment 2

[0075] like Figures 12 to 16As shown, the difference between the second embodiment and the first embodiment is that the clip seat 1 2 and the clip seat 2 3 in the second embodiment are not provided with the installation cavity 9, but the limiting rods 11 are installed on the back plate 12, and the number of the limiting rods 11 is three, and the three limiting rods 11 are arranged in a herringbone shape. The three limiting rods 11 are all located on the inner side of the clip 27, wherein the uppermost limiting rod 11 abuts against the lower end of the pivoting ear 30 of the clip 27, and the two limiting rods 11 below limit the inner side surfaces of the clamping parts 29 of the two clips 27 respectively.
