DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0025] like Figures 1 to 6As shown, the present invention provides a clamping fixture, which includes a base 11, an upper die base 12 lifted and arranged on the base 11, a lower die base 13 located between the upper die base 12 and the base 11, an elastic connecting member 14 connected to the upper die base 12 and the lower die base 13, a clamping driver 15 installed on the base 11 and used to drive the lower die base 13 to approach the upper die base 12, a limiting member 16 installed on the base 11, an upper template 17 arranged on a side of the upper die base 12 close to the lower die base 13, a lower template 18 arranged on a side of the lower die base 13 close to the upper template 17, and an elastic member 19 arranged between the upper template 17 and the upper die base 12, wherein the upper die base 12 is slidably connected to the base 11 via a guide assembly 10 The lower die base 13 is slidably connected with the guide assembly 10, the lower die base 13 is provided with a pressing portion 131, the limiting member 16 is provided with a limiting groove 161, the pressing portion 131 passes through the limiting groove 161, the lower template 18 is provided with a driving surface 171, and a driving device 2 and a loading manipulator are respectively provided on both sides of the clamping fixture, the driving device 2 is used to drive the upper template 17 and the lower template 18 to rise and fall synchronously or to drive the upper template 17 and the lower template 18 to move closer or farther away, the base 11 is driven and connected with a circulating conveying device, and the circulating conveying device is used to drive the clamping fixture to move cyclically along the processing direction; in this embodiment, the clamping fixture holding the battery 7 is taken as an example for explanation.

[0026] During actual operation, the circulating conveying device drives the clamping fixture to move in a circular motion along the processing direction. When the clamping fixture moves to the loading position, the driving device 2 drives the upper template 17 and the lower template 18 to move away from each other, so that the upper template 17 and the lower template 18 are in an open state, and the pressing portion 131 moves downward in the limiting groove 161. Then the loading robot places the battery 7 between the upper template 17 and the lower template 18. At this time, the elastic connecting member 14 is stretched, and the clamping driver 15 is in a compressed state. The driving device 2 releases the driving force on the clamping fixture (the driving device 2 does not apply a driving force to the clamping fixture), and the upper mold base 12 and the lower mold base 13 are close to each other under the action of the rebound force of the elastic connecting member 14. The pressing portion 131 moves upward in the limiting groove 161 until the top wall of the limiting groove 161 contacts the pressing portion 131, so as to limit the pressing portion 131 and thus limit the moving range of the lower mold base 13, thereby ensuring the position accuracy of the upper mold base 12, the lower mold base 13 and the lower mold base 18, and also preventing the upper mold base 17 and the lower mold base 18 from clamping the battery 7 with excessive clamping force and damaging the battery 7. At the same time, the clamping driver 15 applies an upward force to the lower mold base 13, so as to always apply a force close to the upper mold base 17 to the lower mold base 18, thereby further ensuring the stability of the upper mold base 17 and the lower mold base 18 in clamping the battery 7. The lower die base 13 is limited by the limit piece 16 to ensure that the lower die base 13 is at the same height position after each reset, thereby ensuring the position accuracy and stability of the upper die base 12, the upper template 17, the lower die base 13 and the lower template 18. When there are multiple clamping jigs on the circulating conveying device, all the clamping jigs are at the same height position and state during the conveying process, all the clamping jigs are consistent, and when the bearing surface of the lower template 18 is used as the reference surface, it is ensured that the reference surfaces of all the clamping jigs are at the same horizontal plane and the reference surfaces are consistent, so as to improve the accuracy of external processing equipment in processing the battery 7 clamped by the clamping jig, and avoid processing errors and poor processing quality due to inconsistent reference surfaces. Since there are production errors when producing batteries 7, the thickness of each battery 7 is inconsistent. By arranging an elastic member 19 between the upper mold base 12 and the upper template 17, the elastic member 19 has a certain elasticity and can be compressed, which not only allows an adjustment space between the upper mold base 12 and the upper template 17, but also allows it to automatically adapt to batteries 7 of different thicknesses. It has strong practicality, good versatility and a wide range of uses. The contact between the upper template 17 and the battery 7 is also flexible, which plays a buffering and protective role for the battery 7, avoiding damage to the battery 7 due to excessive clamping force, and when the upper template 17 and the lower template 18 clamp the battery 7, the elastic member 19 can also provide a clamping force to the upper template 17, further ensuring the stability of the upper template 17 and the lower template 18 clamping the battery 7.When the clamping fixture holds the battery 7 and moves to the external processing equipment, the driving device 2 applies a downward force to the driving surface 171 of the lower template 18, so that the lower template 18 moves downward. Since the upper mold base 12 and the lower mold base 13 are connected via the elastic connecting member 14, the upper mold base 12, the upper template 17, the battery 7, the lower template 18 and the elastic connecting member 14 move downward synchronously, so that the upper template 17 and the lower template 18 clamp the battery 7 and move down to the processing position. The external processing equipment processes the clamped battery 7. The bearing surface of the lower template 18 is used as the reference surface. The driving device 2 directly drives the driving surface 171 of the lower template 18 to move downward. The driving reference surface is The working reference plane makes the height of the lower template 18 moving downward equal to the height of the battery 7 moving downward. Compared with the driving device 2 driving the upper mold base 12 to move downward and drive the lower mold base 18 to move downward, since there are multiple assembly parts (such as: upper mold base 17, elastic member 19, etc.) between the upper mold base 12 and the lower mold base 18, cumulative errors are easily generated. The downward height of the upper mold base 12 is not necessarily equal to the downward height of the battery 7, which leads to low downward accuracy of the reference plane and inconsistent reference planes. The present invention improves the positioning accuracy of the battery 7 and has high downward accuracy, ensuring that the reference planes of all clamping fixtures remain consistent, thereby improving the accuracy and quality of battery 7 processing by external processing equipment.

[0027] The present invention can automatically adapt to batteries 7 of different thicknesses and firmly clamp them through the ingenious design of the clamping fixture without damaging the batteries 7. The present invention has strong practicality, good versatility, and a wide range of uses. The driving reference plane is the working reference plane, so that the downward movement accuracy of the reference plane is high, which is beneficial to improving the accuracy and quality of the processing of the battery 7 by the external processing equipment.

[0028] In this embodiment, the driving device 2 includes a first frame 21, a pressing mechanism 22 installed on the first frame 21, and a pulling mechanism 23 installed on the first frame 21. The pressing mechanism 22 is used to press the pressing part 131 downward, and the pulling mechanism 23 is used to pull the upper mold base 12 upward.

[0029] When the clamping fixture moves to the loading position, the pressing mechanism 22 applies a downward pressing force to the pressing portion 131, so that the pressing portion 131 moves downward with the lower die base 13 and the lower mold plate 18. At the same time, the pulling mechanism 23 applies an upward pulling force to the upper die base 12 to prevent the upper die base 12 from moving downward with the lower die base 13 under the action of the elastic connecting member 14, so that the upper die base 12 and the lower die base 13 are in an open state, and the elastic connecting member 14 is stretched, so that the upper mold plate 17 and the lower mold plate 18 are in an open state. So that the loading robot can place the battery 7 between the upper template 17 and the lower template 18; when the pressing mechanism 22 releases the downward pressure on the pressing part 131, and the pulling mechanism 23 releases the upward pulling force on the upper mold base 12, the upper mold base 12 and the lower mold base 13 move closer to each other under the action of the rebound force of the elastic connecting part 14, so that the upper mold base 17 and the lower mold base 18 clamp the battery 7, and the clamping driver 15 provides an upward force to the lower mold base 13, so that the upper mold base 17 and the lower mold base 18 can firmly clamp the battery 7.

[0030] Specifically, a handle 121 is provided on the top of the upper mold base 12, and the pulling mechanism 23 includes a pulling driver 231 installed on the first frame 21 and a pulling member 232 installed on the output end of the pulling driver 231, and the pulling driver 231 is used to drive the pulling member 232 to rise and fall, and the pulling member 232 is drivingly connected to the handle 121; specifically, the pulling member 232 is provided with a resistance member 233, and the handle 121 is provided with an upper pulling groove 122, and the resistance member 233 protrudes into the upper pulling groove 122, and the pulling driver 231 is a cylinder.

[0031] When the upper mold plate 17 and the lower mold plate 18 need to be opened, the upper pull driver 231 drives the upper pull member 232 to move upward with the resisting member 233, and the resisting member 233 that moves upward contacts the inner wall of the upper pull groove 122, so that the upper mold base 12 is subjected to an upward pulling force, thereby preventing the upper mold base 12 from moving downward with the lower mold base 13, and thus allowing the upper mold plate 17 and the lower mold plate 18 to be in an open state. The resisting member 233 and the handle 121 are connected in a non-fixed manner, which is convenient for disassembly and maintenance, and facilitates the upper mold plate 17 and the lower mold plate 18 to close the mold under the action of the elastic connector 14 to clamp the battery 7.

[0032] In this embodiment, the pressing mechanism 22 is provided with a lower pressing plate 221, the lower pressing plate 221 is provided with a suction hole 222, the lower mold plate 18 is embedded with a suction nozzle 3, and the lower mold base 13 is provided with an air duct 132. One end of the air duct 132 is connected with the suction nozzle 3, and the other end of the air duct 132 is exposed on the pressing surface of the pressing part 131 and is used to be connected with the suction hole 222. The suction hole 222 is connected with a vacuum extraction device.

[0033] The pressing mechanism 22 drives the lower pressing plate 221 to move downward against the pressing portion 131, so that the lower template 18 and the upper template 17 are opened. During this process, the suction hole 222 is connected to the suction nozzle 3 via the air duct 132, and the vacuum device vacuums the suction hole 222, the air duct 132 and the suction nozzle 3. When the loading robot places the battery 7 on the lower template 18, the suction nozzle 3 sucks the battery 7 tightly onto the lower template 18 to improve the stability and position accuracy of the battery 7 on the lower template 18 until the upper template 17 and the lower template 18 are molded together and clamp the battery 7. During the mold closing process, the battery 7 will not be offset to ensure the stability of the upper template 17 and the lower template 18 to clamp the battery 7.

[0034] In this embodiment, the driving device 2 includes a second frame 24, a lifting drive 25 installed on the second frame 24, and a driving plate 26 installed on the output end of the lifting drive 25. The driving plate 26 is located above the driving surface 171. The driving plate 26 is used to contact the driving surface 171. The lifting drive 25 is used to drive the driving plate 26 to approach or move away from the driving surface 171. The lifting drive 25 is a linear drive module or a cylinder.

[0035] When the clamping fixture moves to the processing position, the lifting driver 25 drives the driving plate 26 to move close to the driving surface 171 until the driving plate 26 contacts the driving surface 171 and moves downward, so that the upper mold base 12, the upper mold plate 17, the battery 7, the lower mold plate 18 and the lower mold base 13 move downward synchronously. The driving surface 171 is both the working reference surface of the lower mold plate 18 and the driving reference surface. The downward height of the driving surface 171 is consistent with the downward height of the battery 7, which improves the positioning accuracy of the downward movement of the battery 7. The downward movement accuracy is high, which ensures that the reference surfaces of all clamping fixtures remain consistent, thereby improving the accuracy and quality of external processing equipment for processing the battery 7.

[0036] In this embodiment, the elastic connecting member 14 includes a fixed seat 141 and a tension spring 142. The tension spring 142 tensions the upper die seat 12 and the lower die seat 13. The fixed seat 141 is installed on the lower die seat 13. The fixed seat 141 is provided with a accommodating cavity 143. One end of the tension spring 142 is connected to the bottom wall of the accommodating cavity 143, and the other end of the tension spring 142 is connected to the upper die seat 12. The tension spring 142 is accommodated in the accommodating cavity 143, and the tension spring 142 is covered to hide the tension spring 142, thereby improving the aesthetic appearance of the clamping fixture, and guiding and protecting the tension spring 142, ensuring that the tension spring 142 can work normally.

[0037] Specifically, there are two tension springs 142 , which are arranged in parallel and can provide sufficient clamping force to the lower template 18 and the upper template 17 .

[0038] Specifically, there are two elastic connectors 14, one end of the upper mold base 12 is connected to one end of the lower mold base 13 via an elastic connector 14, and the other end of the upper mold base 12 is connected to the other end of the lower mold base 13 via another elastic connector 14, so that the upper mold base 12 and the lower mold base 13 are evenly stressed, thereby improving the stability of clamping the battery 7.

[0039] In this embodiment, the elastic member 19 is a spring, which has a simple structure, low cost, good elasticity, long service life, and convenient maintenance and disassembly. Specifically, there are multiple elastic members 19, which are arranged in a rectangular array between the upper mold base 12 and the upper mold plate 17, so that the upper mold plate 17 is evenly stressed, ensuring the stability of clamping the battery 7.

[0040] In this embodiment, an adjusting member 162 is provided at the top of the limiting member 16, and the bottom end of the adjusting member 162 protrudes into the limiting groove 161. Specifically, the adjusting member 162 is an adjusting bolt, and the threaded end of the adjusting bolt is threadedly connected to the top of the limiting member 16, and the nut of the adjusting bolt protrudes into the limiting groove 161 and is used to contact the pressing surface of the pressing portion 131. The adjusting member 162 is screwed so that the adjusting member 162 can move up and down on the top of the limiting member 16, and the length of the adjusting member 162 protruding into the limiting groove 161 is adjusted to adjust the position of the limiting portion 131, thereby adjusting the moving stroke of the pressing portion 131 in the limiting groove 161, and the adjustment is convenient and quick.

[0041] In this embodiment, the number of the upper templates 17 is multiple, and the multiple upper templates 17 are arranged opposite to the lower template 18. The multiple upper templates 17 are arranged horizontally, so that multiple batteries 7 can be clamped at one time, which improves the efficiency of clamping the batteries 7. When the thickness of each battery 7 is different, since the multiple upper templates 17 are independent of each other and do not affect each other, each upper template 17 can automatically adapt to the thickness of the corresponding battery 7 under the action of the elastic member 19. Preferably, the number of the upper templates 17 is two, so as to achieve a one-to-two effect and improve the efficiency of clamping the battery 7.

[0042] Specifically, the number of the limiting members 16 and the number of the pressing portions 131 are both plural, and the limiting members 16 , the pressing portions 131 and the upper mold plate 17 are arranged in a one-to-one correspondence, so that the force on the lower mold base 13 is uniform, thereby improving the stability of clamping the battery 7 .

[0043] In this embodiment, the clamping driver 15 includes a guide seat 151, a guide cylinder 152, a compression spring 153 and a locking piece 154. The bottom end of the guide seat 151 is mounted on the base 11. The top of the guide seat 151 is provided with a guide hole 155. The top of the guide cylinder 152 is connected to the lower mold seat 13. The bottom end of the guide cylinder 152 protrudes into the guide hole 155. One end of the compression spring 153 abuts against the bottom wall of the guide hole 155, and the other end of the compression spring 153 abuts against the inner wall of the guide cylinder 152. The guide cylinder 152 is sleeved outside the compression spring 153. The locking piece 154 is used to limit the guide cylinder 152 on the guide seat 151 to prevent the guide cylinder 152 from detaching from the guide seat 151. The compression spring 153 provides an upward elastic force to the lower die base 13 via the guide cylinder 152, so that the lower die base 13, the lower mold plate 18, the battery 7, the upper mold plate 17, and the upper die base 12 can be automatically reset synchronously, and also provide a clamping force to the lower die base 13. The compression spring 153 is accommodated between the guide base 151 and the guide cylinder 152, which not only protects the compression spring 153, but also guides the compression spring 153 to prevent the compression spring 153 from bending and deforming and failing to work normally. The guide cylinder 152 is guided by the guide hole 155, which improves the stability of the lower die base 13 in lifting and lowering.

[0044] In order to further improve the stability of the lower die base 13 during lifting and lowering, the lower die base 13 is also slidably connected to the base 11 via the guide assembly 10 .

[0045] In this embodiment, the upper die seat 12 is connected to the upper die plate 17 via a positioning guide 4, and the positioning guide 4 includes a nut portion 41, a guide column portion 42 and a threaded portion 43 connected in sequence, the threaded portion 43 is threadedly connected to the upper die plate 17, the guide column portion 42 is slidably connected to the upper die seat 12, and the nut portion 41 is used to abut against the top surface of the upper die seat 12 to limit the upper die plate 17. The positioning guide 4 of this structural design not only realizes the connection between the upper die seat 12 and the upper die plate 17, but also enables the upper die plate 17 to move relative to the upper die seat 12, so that the upper die plate 17 can automatically adapt to the thickness of the battery 7 under the action of the elastic member 19 to achieve automatic adjustment.

[0046] Specifically, a gasket 5 is arranged between the nut portion 41 and the top surface of the upper mold base 12. The upper mold base 12 is embedded with a sliding sleeve that is slidably connected to the guide column portion 42. The sliding sleeve is arranged outside the guide column portion 42 and is slidably connected to the sliding sleeve through the guide column portion 42. The friction resistance is small, which improves the stability of the upper mold plate 17 moving relative to the upper mold base 12.

[0047] Specifically, the guide assembly 10 includes a guide rod 101, a guide sleeve 102 and a limit cover 103. The top of the guide rod 101 is mounted on the upper mold base 12, the guide sleeve 102 is mounted on the base 11, the guide rod 101 is slidably connected to the guide sleeve 102, and the limit cover 103 is mounted on the bottom of the guide rod 101. The limit cover 103 is located below the base 11. Specifically, there are four guide assemblies 10, and the four guide assemblies 10 are arranged in a rectangular array. The guide rod 101 is slidably connected to the guide sleeve 102, which improves the stability of the upper mold base 12 in lifting and lowering, and the limit cover 103 is used to contact the bottom surface of the base 11 to limit the maximum upward position of the upper mold base 12, prevent the upper mold base 12 from being separated from the base 11, and ensure the stability of the upper mold plate 17 and the lower mold plate 18 clamping the battery 7.

[0048] All technical features in this embodiment can be freely combined according to actual needs.

[0049] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
