Description

Technical Field

[0001] The utility model relates to a fixture, in particular to a dispensing and fixing fixture. Background Technique

[0002] During the process of battery production, the battery case and the battery cover need to be sealed with glue. After dispensing, the battery cover needs to be pressed and fixed on the battery case and left for a period of time until the glue is completely cured to ensure good sealing of the battery cover. A fixing fixture is required for use.

[0003] For example, a special fixture for battery dispensing and fixing with a publication number of CN214864930U disclosed in a Chinese patent includes: a bottom plate; a pressing plate arranged above the bottom plate, and a receiving portion for receiving the battery is formed between the pressing plate and the bottom plate; and a pressing assembly for driving the pressing plate to press down and lock, so that the pressing plate continuously presses the battery located in the receiving portion. Through the arrangement of the bottom plate, the pressing plate and the pressing assembly in the above technical solution, the battery is clamped between the bottom plate and the pressing plate and can maintain the clamping force, meeting the requirements of sufficient pressure and saving manpower, liberating the labor force, enabling the operator to do more work, saving labor costs, reducing the cost of assembling batteries for battery production enterprises, and improving the economic benefits of the enterprise; and by clamping the battery with the special fixture for battery dispensing and fixing in the above technical solution, compared with continuous manual pressing, the pressure is more uniform, and the stability and continuity are better;

[0004] Some problems are found when using the above existing special fixture for battery dispensing and fixing. First, during the dispensing process, the pressing assembly has two limit positions, and it can only clamp and process two different models and sizes of batteries, with a low application range. Second, for different models of batteries, the materials used are also different, so the clamping force needs to be changed to a certain extent, and the device cannot adjust the clamping force. Content of the Utility Model

[0005] The purpose of the utility model is to provide a dispensing and fixing fixture to solve the existing problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A dispensing and fixing fixture includes a base, and limiting slide bars are fixedly connected to positions near the two corners at the back of the upper surface of the base. A clamping plate is slidably installed on the limiting slide bars. A threaded sleeve shaft is fixedly connected to the upper surface of the clamping plate. A weight tray is sleeved on the threaded sleeve shaft. A connecting rod is arranged between the two limiting slide bars. Sleeve rings are fixedly connected to both ends of the connecting rod. The sleeve rings are slidably matched with the limiting slide bars. A pushing spring is sleeved on the limiting slide bars.

[0007] Preferably, a limit cap is fixedly connected to the upper end of the limit slide bar, and fixing holes are formed in the opposite surfaces of the two limit slide bars.

[0008] Preferably, sliding holes are formed at positions near the two rear corners inside the clamping plate. The sliding holes are in sliding fit with the limit slide bars, and a fixing nut is threadedly installed on the threaded sleeve shaft.

[0009] Preferably, a through hole is formed in the weight pan, and the through hole is matched with the threaded sleeve shaft.

[0010] Preferably, a pressing head is fixedly connected to the rear of the connecting rod.

[0011] Preferably, limiting grooves are symmetrically formed in the rear of the connecting rod. A return spring is fixedly connected in the limiting grooves. The other end of the return spring is fixedly connected with a limiting pin. The limiting pin is matched with the fixing hole. A displacement handle is fixedly connected to the limiting pin.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. By moving the connecting rod downward to drive the collar to move, after the clamping plate loses the thrust of the collar, due to gravity, it will naturally fall on the battery. Utilizing the weights of the clamping plate and the weight pan, and cooperating with the base to clamp and press the battery, the clamping plate will apply a stable downward pressure to the battery, without being affected by the changes in the height and size of the battery, and is applicable to the dispensing, fixing, pressing, and clamping of batteries of different models and sizes.

[0014] 2. By sleeving the weight pan on the threaded sleeve shaft, by increasing or decreasing the number of weight pans, the downward pressure of the clamping plate on the battery can be changed, so that the downward pressure can be reduced or increased according to the material of the battery, ensuring that the best pressing and clamping force can be achieved.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a dispensing and fixing fixture, including a base 1. At positions near the two corners at the back on the upper surface of the base 1, a limit slide bar 101 is fixedly connected. A clamping plate 2 is slidably installed on the limit slide bar 101. A threaded sleeve shaft 201 is fixedly connected to the upper surface of the clamping plate 2. A weight pan 3 is sleeved on the threaded sleeve shaft 201. A connecting rod 4 is arranged between the two limit slide bars 101. Collars 401 are fixedly connected to both ends of the connecting rod 4. The collars 401 are slidably matched with the limit slide bars 101. A pushing spring 104 is sleeved on the limit slide bar 101.

[0022] In this implementation manner, the pushing spring 104 can provide a certain thrust for the collar 401. The collar 401 driven by the thrust will drive the clamping plate 2 to move upward, so that the clamping plate 2 is in a suspended state. A sufficient gap is left between the base 1 and the clamping plate 2 to place the battery. Moving the connecting rod 4 downward will drive the collar 401 to move, and the collar 401 will compress the pushing spring 104. After the clamping plate 2 loses the pushing support of the collar 401, the clamping plate 2 will move downward to contact the upper surface of the placed battery, so as to clamp the battery by its own weight and the weight of the weight pan 3. Thus, the clamping plate 2 will apply a stable downward pressure to the battery, without being affected by the changes in the height and size of the battery, and is applicable to the dispensing and fixing pressing of batteries of different models and sizes. By increasing or decreasing the number of weight pans 3, the downward pressure of the clamping plate 2 on the battery can be changed, so that the downward pressing force can be reduced or increased according to the material of the battery to ensure that the best pressure clamping force can be achieved.

[0023] Among them, in order to achieve the purpose of fixing the weight tray 3, the following technical solution is adopted in this device: A limit cap 102 is fixedly connected to the upper end of the limit slide bar 101. Fixing holes 103 are provided on the opposite surfaces of the two limit slide bars 101. Slide holes 203 are provided at positions near the two rear corners inside the clamping plate 2. The slide holes 203 are slidably matched with the limit slide bars 101. A fixing nut 202 is threadedly installed on the threaded sleeve shaft 201. A through hole is provided in the weight tray 3, and the through hole is mutually matched with the threaded sleeve shaft 201.

[0024] By the sliding fit between the slide holes 203 and the limit slide bars 101, the clamping plate 2 is slidably installed on the limit slide bars 101. The limit cap 102 is used to limit the moving stroke of the clamping plate 2 to prevent the clamping plate 2 from moving out of the limit slide bars 101. The weight tray 3 is placed on the threaded sleeve shaft 201 through the provided through hole. By adjusting the number of weight trays 3, the weight tray 3 can be fixed on the threaded sleeve shaft 201 by using the fixing nut 202.

[0025] Among them, in order to achieve the purpose of fixing the position of the collar 401, the following technical solution is adopted in this device: A pressing head 402 is fixedly connected to the rear of the connecting rod 4. Limit grooves 5 are symmetrically provided on the rear surface of the connecting rod 4. A return spring 501 is fixedly connected inside the limit grooves 5. The other end of the return spring 501 is fixedly connected to a limit pin 502. The limit pin 502 is mutually matched with the fixing hole 103. A displacement handle 503 is fixedly connected to the limit pin 502.

[0026] The pressing head 402 facilitates pressing the connecting rod 4 to move downward. The return spring 501 can provide a certain thrust for the limit pin 502. The limit pin 502 will move out under the thrust and insert into the fixing hole 103, thereby clamping the collar 401 on the limit cap 102, so that the collar 401 is separated from the clamping plate 2, avoiding continuously providing thrust to the clamping plate 2 through the collar 401. The displacement handle 503 can drive the limit pin 502 to move, so that the limit pin 502 moves out of the fixing hole 103.

[0027] The working principle and usage process of the present utility model: When in use, the device needs to be placed in a suitable position. The battery to be pressed is placed between the base 1 and the clamping plate 2. Press the pressing head 402 to drive the connecting rod 4 to move downward. The downward movement of the connecting rod 4 will drive the collar 401 to move downward. The downward movement of the collar 401 will compress the pushing spring 104. When the limit pin 502 is inserted into the fixing hole 103, the pressing head 402 can be released. After the clamping plate 2 loses the support of the collar 401, due to gravity, it will naturally fall on the battery. By using the weights of the clamping plate 2 and the weight tray 3, and cooperating with the base 1, the battery is clamped and pressed. After a certain period of time, when the glue is cured, move the displacement handle 503 to drive the limit pin 502 to move out of the fixing hole 103. At this time, the pushing spring 104 will drive the collar 401 to reset upward, thereby pushing the clamping plate 2 to move upward to release the pressing on the battery, and the battery can be easily removed.

[0028] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
